BIP-1: Daily PVP

[SotaTek-AnNguyen]

Abstract

One element that was missing in the Bunicorn Game and many other P2E games is the competitive element between player vs. player. This missing factor attracts only the ones that play for profit instead of winning in the actual gameplay while it is the main revenue stream of traditional games. Bunicorn's PvP Arena will be our next attempt to fill in the missing piece. We will also share how we shape the future of the Bunicorn Metaverse with the creation of Buniland NFTs and change the way players and the platform owner earns revenue.

As the first step towards building the Buniland metaverse, we will start building some places in the Buniland that correspond to different features of the game. The PvP Arena are buildings in the Buniland to host the fights between player vs player and will be able to generate revenue from the fights. The first PvP mode is Daily PvP. Below is a draft of how it’s going to be implemented.

Goals

• To create a new playing mode that focuses more on the gaming experience with complex strategies in addition to the normal PvE/Dungeon battles.
• To create a top-ranking leaderboard to encourage the competitiveness between player-vs-player.
• PvP will be divided by tiers so that even low-level Trainers or Bunicorn can have their own ranking leaderboard.

Specifications

New terminologies

Pair & Tier

• Each 1 pair includes 1 Trainer and 1 Bunicorn
• The tier of a pair is determined by the level of Trainers and the star of Bunicorn, such as:
  • Level 1-10 Trainer & 1-star Bunicorn
  • Level 1-10 Trainer & 2-star Bunicorn
  • …
  • Level 1-10 Trainer & 5-star Bunicorn
  • ...
  • Level 41-50 Trainer & 1-star Bunicorn
  • ...
  • Level 41-50 Trainer & 5-star Bunicorn

Team

• To join PvP battle, each user needs to register their team, each team has a maximum of 4 pairs at the same tier
• Each Trainer/Bunicorn cannot be in 2 pairs at the same time
• Each pair cannot be in 2 teams at the same time
• Team & pair will be registered on-chain via smart contracts. All the Trainers/Bunicorns in a team cannot be transferred or sold in the market.
• Un-registering a team will make them transferable again but their PvP ranking & rewards will be canceled.
• Each player can form multiple teams in different tiers, but only maximum 1 team per tier.

Match-making

• We use the ELO/MMR to rank the teams
• Players can have multiple PvP fights per day. After one fight, they’ll need to wait for at least 15 minutes to start another PvP fight.
• To start a PvP fight, a player will pick 1 pair in his team to fight with a pair in another team below or above 10 ranks in the same tier.
• The selected team and pair of the opponent is determined randomly. Thus, if a team has 4 pairs in 4 elements, it would be difficult to have elemental advantages for the one who starts the fight.

Ranking PVP modes

• All users are free to join the daily PvP. However, it is possible to join it with some BUR for those who are confident with his army and strategies and want to earn some extra money through random PvP fights.
• If you fight with a free player, only the battle result, ELO and ranking are recorded.
• If you fight with another player that both of you decided to use BUR, you can earn a fixed amount of BUR per victory, and a commission is paid to the Arena.

Duel challenge

• One user can pay some fee to challenge a team ranked higher than him directly. If he wins, the ELO and rank will be swapped.
• Each player can only challenge 1 time per hour.
• The fee of duel challenges will be the revenue of the Arena.

Spar

After the daily PvP ranking is introduced, we will start working on other types of PvP such as fighting PvP as a team/guild or directly challenging someone and bet for the result as below:

• User A submits a challenge request to user B with some basic pair information and an amount of BUR.
• User B rejects or accepts the challenge with the same amount of BUR.
• When both A & B are ready without knowing the full team formation of the opponent, the fight starts. Some BUR comes to the winner, the rest go to the Arena.

Honor point

• Apart from ELO/MMR, each team will have another point called Honor. In the beginning, the honor is 0.
• After each PvP battle, the winner will receive 10 Honor and half of the Honor point of the opponent. The defeated team’s Honor will be reset to zero.
• Honor is a special stat that increases the chance to meet enemies at dungeons and increases the baseline reward in normal PvE.

Rankings

• The system will update the ranking in 0:00-1:00 UTC every day. PVP will be disable during this period.

Arena NFT

• There will be a special NFT for each tier called Arena NFT that will be awarded to the top 1 PvP players daily.
• After one day, all revenue from direct challenges or paid fights from all Arenas in Buniland will be collected. A portion of it will come to the game treasury while the rest will be given to the owner of the Arena NFTs.
• Higher tier Arena will receive higher rewards.

Battle & Gameplay

Unlike the PvE mode, this new feature uses a more complicated method that takes into account Bunicorn attributes, Trainers, items,... The ultimate goal is to have a fair and competitive battle where no one has absolute power to constantly rule the Arena. In the first version, the Trainers are at the same level on each tier, so the battle result almost only depends on the Bunicorn.

Attributes

• Each Bunicorn will have 4 different attributes:
  • Attack (Damage) = Fire
  • Vitality (HP) = Earth
  • Agility (Speed) = Air
  • Regeneration = Water / 2
• The attribute has same element as bunicorn's element will be boost by 20% (to be adjusted)
• Apart from the elemental attributes of the Bunicorn, it also has neutral & bonus attributes that they gained through enhancing. Besides, each Bunicorn will be given an additional base attribute depending on its star (these are just example, the actual numbers will be calculated & finalized later):
  • 1-star: 100
  • 2-star: 200
  • 3-star: 300
  • 4-star: 600
  • 5-star: 1000
• There may be some fixed base elemental attributes, this is also under calculation and will be revealed soon.
• Players can distribute these neutral, bonus and base attributes to one of the 4 Attack, Vitality, Agility or Regeneration based on their own strategies. For example:
  • User has a 4-star Bunicorn with +300 Fire, +290 Neutral, +200 Bonus Attribute. By default, he has +300 attack & 600+200+290=1090 neutral points.
  • He can decide to distribute these 1090 neutral points to:
  • 500 vitality + 500 agility + 90 regeneration + 300 attack
  • 300 vitality + 600 agility + 0 regeneration + 490 attack
  • or any other distribution based on his strategy..
• All players can adjust to the settings to distribute their neutral points in advance or the system will distribute randomly to create different strategies from time to time and avoid being exploited from repetitive fights.

Auras

• Aura is an item to support Bunicorns in battle. It will be activated in the Preparation Phase (which will be described below). Each player will have 4 default auras (also subject to be adjusted after calculation):
  • Increase all attributes of his Bunicorn by 10%
  • Decrease all attributes of the enemy’s Bunicorn by 10%
  • Increase the HP of his Bunicorn by 25%
  • Increase the ATK attribute of his Bunicorn by 25%
• Player can choose maximum 2 (can be adjusted too) auras to be used for his battle.
• The default aura will be permanent, but there will be other auras which is consumable (you can use only once).
• There will also be more auras with more different effects, can be collected from PVE and Dungeons. Player can trade the auras as other items on the market.

Spells

• Spell is another item to support Bunicorn in battle. It will be activated during Action Phase (will be described below)
• Spell is consumable and can be collected via PVE and Dungeons, and of courses tradable as any other items.
• Some example effects of spell:
  • Shield: block one opponent's attack
  • Pierce: attack through opponent's shield
  • Dodge: Reduce taken damage from enemy by 80%
  • Berserk: increase damage of bunicorn by 30%
  • Poison: deal 100 damage to opponent after every 200 time units
  • etc..

Equipments

• Will be revealed in the next version (can see #3)

Battle

• The first version of battle will includes 3 main phases:
  • Preparation phase: activate the aura for the both sides
  • Action phase: bunicorns will attack each other, will described more detailed below
  • End phase: battle will be concluded if one of bunicorn's HP is 0 or below. If battle is timed out but both bunicorns still alive, the one with more HP will win the fight.
• Element advantage is still effective in pvp battle

Battle action phase

• Action phase is designed as an active time battle, and running fully autonomously.
• The unit of time in battle is called tick. When the action phase is started, a timer will be triggered as well.
• Both bunicorn will take their move during action phase, until one is down or a certain units of time is passed.

Bunicorn's move

• Bunicorn can take a move everytime a certain number of ticks is passed, which is equal to 1,000,000 / {agility}
  • For example: agility = 500 → bunicorn will perform its move every 2000 ticks.
  • The bunicorn with great agility may take multiple moves before the opponent can. For example:
  • Bunicorn A has agility = 500 → can perform move every 2000 ticks
  • Bunicorn B has agility = 150 → can perform move every 6667 ticks
  • So in the battle, bunicorn A will take 3 moves first (at 2000, 4000, 6000 ticks), then bunicorn B can perform its move (at 6667 ticks).
  • If 2 bunicorns have the same agility, the order of move will be selected randomly.
• When a bunicorn is performing its move, there're several states come in sequence:
  • First is the regenerating state: increase bunicorn's current HP to a value equal to regeneration (water) attribute. The HP of bunicorn cannot exceed max HP (earth) attribute.
  • Second is the attack spell activation state: the attack spell of this bunicorn (if any) can be activated.
  • Third is the defense state of opponent: the defense spell of the opponent (if any) can be activated.
  • Third is the attack state: bunicorn perform the attack to the opponent. If the attack is successful, the opponent's HP will be decreased and amount equal to the bunicorn's damage. The advantage of element is still effective in the pvp battle.
• The moves will happen continuously until a bunicorn's HP is reduced to 0 or battle is timed out. Tentatively the duration is 20,000 ticks (can be adjusted later).

Spell setup

• As described in bunicorn's move section, there're 2 main types of spells: attack spell & defense spell, which can be activated in the corresponding state of bunicorn.
• Player can setup the trigger condition of spells to achieve the strategy, for example:
  • Attack: activate pierce if my damage is greater than opponent's current HP
  • Defense: activate shield if my HP is less than opponent's damage
  • etc..

First of all, I cannot understand the arena NFT for 1st per tier system. Why do you put the abnormal reward? If then, Who wanna upgrade their tier?? everyone will try to get lower tier.

Second things, What the mean of The defeated team’s Honor will be reset to zero? One defeat means I can lose all of chance to dungeon and reward baseline?? That indicates 1st team only get the reward from pvp.

You do not need to make the complicate rules of pvp system, just give high rewards if they have enough strong power.

[SotaTek-AnNguyen]

hi @Hyeongsun , thanks for your questions. Let me elaborate them.

First of all, I cannot understand the arena NFT for 1st per tier system. Why do you put the abnormal reward? If then, Who wanna upgrade their tier?? everyone will try to get lower tier.

The low tiers have a lot more players than the high ones, so the competitiveness is actually more intense. Plus the high tiers got more shares & rewards, so people will be encouraged to climb rank on the high tiers.

Second things, What the mean of The defeated team’s Honor will be reset to zero? One defeat means I can lose all of chance to dungeon and reward baseline?? That indicates 1st team only get the reward from pvp.

The honor point is just the bonus. This means:

• If you get the high honor points, you will have a better reward baseline.
• If you don't have any honor point, the reward baseline is just same as current formula. There's no penalty here, and of course lose all of chance to dungeon and reward baseline is not a real scenario.

You do not need to make the complicate rules of pvp system, just give high rewards if they have enough strong power.

Thank you for the opinion, this is actually done in PVE system. For PVP, we want to introduce a system that players can really play and enjoy the game, and consume the items which are produced by PVE and dungeons.

Hope it answers your concerns.

I am also against "The defeated team’s Honor will be reset to zero". This is so futile that it lowers motivation and makes Honor Points to be considered meaningless. I hope it can be used as a more valuable and motivating function. Thank you.

I agree, maybe its good if they deduct only 5 points and not zero. Having a zero rule is a bit scary to some players, they will become hesitant to participate. Especially if they don't trust their own team.

[October89Falls]

I'm a bit confuse about the "unit of time or ticks" and how agility affects it, kindly explained it in a more simple way?

If you don't participate, you have no honor. But you can try and get some of them for free, so why do you hesitate? Please keep in mind honor is just bonus point, zero-honor doesn't mean a penalty to players.

[Chubby-Chocobo]

I'm a bit confuse about the "unit of time or ticks" and how agility affects it, kindly explained it in a more simple way?

You can imagine tick is second. The agility means number of moves your bunicorn can perform in 1,000,000 seconds (this number can be adjusted later). For example we have a scenario:

• Bunicorn A has 500 agility → it can perform a move every 2000 seconds
• Bunicorn B has 200 agility → it can perform a move every 5000 seconds
• When the battle start, the timer will count from 0 second.
  • At 2000th second, the bunicorn A will perform a move
  • At 4000th second, the bunicorn A continue perform another move
  • At 5000th second, the bunicorn B can perform its first move

Hope that example is clear enough.

I don't understand the phrase below. Would you be more specific? "The selected team and pair of the opponent is determined randomly. Thus, if a team has 4 pairs in 4 elements, it would be difficult to have elemental advantages for the one who starts the fight."

[SotaTek-AnNguyen]

I don't understand the phrase below. Would you be more specific? "The selected team and pair of the opponent is determined randomly. Thus, if a team has 4 pairs in 4 elements, it would be difficult to have elemental advantages for the one who starts the fight."

Let's say you have ELO 2000, then when you seek an opponent for a pvp match, the system will choose through the steps:

• Select a random player who has ELO from 1950 to 2050.
• If that player's team has more than 1 pair, then the pair will also be selected randomly.

This random match-making system will prevent players from selecting the weak opponent for a sure-win match. Duel challenge is a special mode that help you specify a particular player to battle, but you can only use it with a higher rank opponent.

[trivia218]

Is there a plan to integrate wagering/betting into the PVP system? Not just the internal betting between both parties but where outsiders or bystanders can also bet on their match.

[MIN4447]

Being able to make up to four pairs means that if you play pvp in one pair, how do you fight when you meet two to four pairs of teams? How many times do you fight in optimal conditions?

[MIN4447]

I wish this system would be added. In pvp ranking mode, when you fight a higher ranker than yourself, you can randomly get 1.3 to 2 times the burr by walking the burr.

The reward may be burr and scroll.

If you lose, the betting burr will disappear.

What's important here is that we need a betting system. Don't forget that bnx has grown into a betting system and honest operation.

First of all, i think this gameplay can work well, it looks complex enough to add some depth to the strategies required by each player, while simple enough so that anybody can understand it once they try it out for a bit.

However, while the competitive nature of players can make them do some irrational decisions, most of the time the players will factor the expected returns or rewards while making an investment in order to be more competitive. As such, i think it's important to evaluate how to give proper value and incentives to the players so that they are willing to spend on this new feature. Overall, I think arena pvp should be THE most rewarding event on the bunicorn universe. As such, i think once Hunters Inc "breeding" system comes to play, its revenue should be shared with the arena, and not made into a "company". Breeding will be the main source of income FROM the players to the game, but to give it value, you need to ensure that this income is going back to the players. Land owners and other type of passive income investors revenue should come from generating materials on their lands, fees from crafting equipments on the foundry, spells and all kind of items that will aid in the arena. This places active investors (the players) in the primary role, where there are higher risks and higher rewards to be made, while passive investors (land owners) have an auxiliary role, where they get a more fixed type of income.

Below I state some rough ideas that I believe could improve the current reward system to make it more enticing, while forcing people to be active and willing to spend resources in order to increase their chances at getting rewards:

1- In this scenario, i think the rewards being given only to the top 1 player of each tier makes it so that a lot of people, restricted by their budget, will opt to not participate in the pvp. I suggest to consider reducing the amount of tiers (for example, a lvl 50 trainer with a 1 or 2 star doesn’t make much sense), but increasing the number of winners per tier. I also suggest to make this number of winners be variable. For example, at the end of the day, a random number between 30 and 50 is chosen, so that the top 30-50 players in each tier are rewarded with part of the arena's revenue. Since the players will not know the exact rankings that are being rewarded, they will need to make decisions and take risks if they want to increase their chances of being chosen, which will lead to more people opting to burn BUR.

2- Secondly, the fact that people can burn BUR to challenge a higher ranking player, and take their spot, doesn't sound too appealing. With these, anybody can simply watch people struggling to climb the ladder and then go and challenge a higher ranking minutes away from the daily ranking closing. Some mechanism that takes into account the amount of battles won, the enemies rankings or the amount of time the player is able to stay in a certain rank could be used to incentivice people to actively take part in the pvp feature and give the more active players a higher chance to get rewards. Also, even if you burn BUR, you should only be allowed to challenge someone that's not too far away from you on the ranking, that way you can't just jump out of nowhere to the top 10.

3- Finally, i think the honor system could be made with a similar mechanism stated above, so that people can only earn honor and not lose it. It could be given only in battles that involve BUR (or at least be higher in these). While honor can't be lost by losing, the factor by which honor affects rewards and dungeons could be relative to the mean of the honor between all the players, so that while you can't lose honor, your bonus becomes smaller if you don't fight to get more (other alternative would be to make it so you need to get at least 1 win every x amount of time in order to keep your honor). This way, honor acts as an incentive for people that can't get on the rankings to still participate and even use some BUR in the fights.

[Chubby-Chocobo]

Is there a plan to integrate wagering/betting into the PVP system? Not just the internal betting between both parties but where outsiders or bystanders can also bet on their match.

Yes. There was a plan for everyone to bet on the spar show matches like that, and also bet on the winner of the tournament.

[Chubby-Chocobo]

Being able to make up to four pairs means that if you play pvp in one pair, how do you fight when you meet two to four pairs of teams? How many times do you fight in optimal conditions?

Even your opponent has 4 pairs, you'll still fight with other 1 pair only, which will be selected randomly. If your team have only 1 pair, for example Fire trainer + bunicorn, another player can abuse by always using Water pair to play against you and take advantage. That's why you may want to setup other pairs with different element.

[Chubby-Chocobo]

I wish this system would be added. In pvp ranking mode, when you fight a higher ranker than yourself, you can randomly get 1.3 to 2 times the burr by walking the burr.

The reward may be burr and scroll.

If you lose, the betting burr will disappear.

What's important here is that we need a betting system. Don't forget that bnx has grown into a betting system and honest operation.

Thank you, we'll consider this and announce the rule in the upcoming updates.

Overall, I think arena pvp should be THE most rewarding event on the bunicorn universe. As such, i think once Hunters Inc "breeding" system comes to play, its revenue should be shared with the arena, and not made into a "company". Breeding will be the main source of income FROM the players to the game, but to give it value, you need to ensure that this income is going back to the players. Land owners and other type of passive income investors revenue should come from generating materials on their lands, fees from crafting equipments on the foundry, spells and all kind of items that will aid in the arena. This places active investors (the players) in the primary role, where there are higher risks and higher rewards to be made, while passive investors (land owners) have an auxiliary role, where they get a more fixed type of income.

We surely will let the income go back to the players. But sharing Hunters Inc's revenue with pvp arena is still under consideration. We have plan for a lot of other roles in Buni universe, and revenue from Hunter Inc should go to its owners/stakeholders, that's more natural - like the example of land owner you mentioned.

1- In this scenario, i think the rewards being given only to the top 1 player of each tier makes it so that a lot of people, restricted by their budget, will opt to not participate in the pvp. I suggest to consider reducing the amount of tiers (for example, a lvl 50 trainer with a 1 or 2 star doesn’t make much sense), but increasing the number of winners per tier.

Since the players will not know the exact rankings that are being rewarded, they will need to make decisions and take risks if they want to increase their chances of being chosen, which will lead to more people opting to burn BUR.

This is daily pvp, and there's no entrance fee so budget is not the problem. We'll consider your suggestion for reward system of PVP Tournament, which is proposed in #2

2- Secondly, the fact that people can burn BUR to challenge a higher ranking player, and take their spot, doesn't sound too appealing. With these, anybody can simply watch people struggling to climb the ladder and then go and challenge a higher ranking minutes away from the daily ranking closing. Some mechanism that takes into account the amount of battles won, the enemies rankings or the amount of time the player is able to stay in a certain rank could be used to incentivice people to actively take part in the pvp feature and give the more active players a higher chance to get rewards. Also, even if you burn BUR, you should only be allowed to challenge someone that's not too far away from you on the ranking, that way you can't just jump out of nowhere to the top 10.

We use the Chess' ELO system, it should be efficient enough to reflect the actual performance of players. Challenge mode is just an extra mode to increase the difficulty of keeping the 1st position. Totally agree with you should only be allowed to challenge someone that's not too far away from you on the ranking, this is exact thing we'll do.

3- Finally, i think the honor system could be made with a similar mechanism stated above, so that people can only earn honor and not lose it. It could be given only in battles that involve BUR (or at least be higher in these). While honor can't be lost by losing, the factor by which honor affects rewards and dungeons could be relative to the mean of the honor between all the players, so that while you can't lose honor, your bonus becomes smaller if you don't fight to get more (other alternative would be to make it so you need to get at least 1 win every x amount of time in order to keep your honor). This way, honor acts as an incentive for people that can't get on the rankings to still participate and even use some BUR in the fights.

If honor always increases for all people, but the bonus is calculated relatively to the sum across all players, the scenario like this will happens:

• today I have 100 honor point, which is equal to average, and I get 10% bonus reward in PVE
• tomorrow I have 200 honor point, but other players got 500 points in average, then my bonus is only 5%
• next week I have 1000 honor point, while the average is 10000 now, my bonus is 1% IMHO it doesn't make sense.

I feel people are too sensitive with the lost word. Honor is just a bonus you can get in a total free playing mode (daily pvp). If you pay attention and have a strategy, you can get the bonus, otherwise there's no harm. Why are you always afraid of losing honor point?

Btw, we'll bring all of these ideas to the team and discuss more carefully. Thank you for very supportive & constructive comment @gammaJPG

[gammaJPG]

This is daily pvp, and there's no entrance fee so budget is not the problem.

On this regard, when i say they are restricted by budget, i mean they don't have enough to upgrade their team to be competitive enough to even have a chance. If they don't have a chance to be top 1, and that's the only way they get rewards from the arena, then they will just not play, even if the entrance is free. If only the 10 people per rank that might have a chance to get that rank 1 spot are playing, then there's not much point to make this arena feature on the first place, which goes to my second point, the honor system:

If honor always increases for all people, but the bonus is calculated relatively to the sum across all players, the scenario like this will happens:

• today I have 100 honor point, which is equal to average, and I get 10% bonus reward in PVE
• tomorrow I have 200 honor point, but other players got 500 points in average, then my bonus is only 5%
• next week I have 1000 honor point, while the average is 10000 now, my bonus is 1% IMHO it doesn't make sense.

I feel people are too sensitive with the lost word. Honor is just a bonus you can get in a total free playing mode (daily pvp). If you pay attention and have a strategy, you can get the bonus, otherwise there's no harm. Why are you always afraid of losing honor point?

Yes, there is no harm in losing something that only acts as a bonus, but if the chances of losing it are too high, then the bonus is too weak to be a motivational factor for people to play the arena. In my opinion, the honor system, as you proposed it, doesn't change anything, so it doens't matter whether it's implemented or not. Instead, i'm trying to envision honor as something that people try to constantly gain, in order to increase their potential gains. That way, even if the people can't get direct rewards from the arena, they will get indirect rewards from increased pve and dungeon rewards.

I forgot to mention that for the honor relative to the mean system to work, honor would need to be reset every x amount of time (every week maybe), otherwise new players will be too left behind. That said, im not sure why you say it doesn't make sense, it simply means that people that are more active and do pvp are more likely to get a bigger bonus, this incentivices people to play the pvp frequently and to improve to get more wins. It doesn't need to work this way though, but what's important is that there is at least 1 kind of reward for the people that play arena and perform good, otherwise a lot of the items such as auras/skills/equipment will lose their value and they will not have a relevant place in the economy.

Regarding Hunter Inc, I might have made a mistake. I was thinking of new players getting their bunis there, when in fact only existing players can get bunis from it, and then they can sell them on the marketplace. So the most important and stable source of income is not Hunter Inc, but the Marketplace . So Hunter Inc could still be made into players ownership, as long as the marketplace remains public (although there could be some interesting interactions, like treasury bonds the players can purchase).
