Quest System: Review and modify quest.js and NPCS.js #49

Closed maxcurrent420 closed 10 months ago

maxcurrent420 commented 10 months ago

Please review quest.js and NPCs.js and make sure the code fully implements at least one type of basic quest, and works properly with the rest of the game.

I want the game to conform to the goals in the Readme.md and Project Roadmap, allowing a monster breeding game with quests enabled. I want the quests to involve using the monsters that have been bred, such as having them search for something or vanquish baddies, when assigned by a village elder NPC for example.

Potential solution

To implement the basic quest system and ensure it works with the rest of the game, we need to integrate the quest mechanics into the existing game structure. This involves updating the Monster class to participate in quests, refining the Quest class to handle quest logic, and ensuring that NPCs can assign quests. We also need to ensure that the battling system can be triggered from a quest context and that the breeding system produces monsters with relevant traits for quests.

Code

// File: monster.js
class Monster {
  // ... existing properties and methods ...

  // Add quest-related properties and methods
  questStatus = 'idle'; // Possible values: 'idle', 'active', 'completed'
  currentQuest = null;

  startQuest(quest) {
    this.questStatus = 'active';
    this.currentQuest = quest;
    // Additional logic to handle quest start
  }

  updateQuestProgress(progress) {
    if (this.questStatus === 'active' && this.currentQuest) {
      // Update quest progress here
      // If quest is completed, update questStatus to 'completed'
    }
  }

  completeQuest() {
    if (this.questStatus === 'completed' && this.currentQuest) {
      // Reward the monster or player for completing the quest
      this.questStatus = 'idle';
      this.currentQuest = null;
    }
  }

  searchForItems() {
    if (this.questStatus === 'active' && this.currentQuest) {
      // Implement item search logic based on monster's attributes and quest requirements
    }
  }

  // Additional methods for quest-related activities can be added here
}

// File: components/quest.js
export class Quest {
  // ... existing properties and methods ...

  // Revised constructor and methods
  constructor(name, difficulty, rewards, tasks = []) {
    this.name = name;
    this.difficulty = difficulty;
    this.rewards = rewards;
    this.tasks = tasks;
    this.isActive = false;
    this.isCompleted = false;
  }

  startQuest() {
    this.isActive = true;
    // Logic to start the quest
  }

  updateProgress(taskId, progress) {
    // Logic to update task progress
  }

  checkCompletion() {
    // Logic to check if all tasks are completed
  }

  completeQuest() {
    this.isCompleted = true;
    // Logic to complete the quest and give rewards
  }
}

// File: screens/battling.js
import QuestSystem from '../quest/QuestSystem.js'; // Import the quest system

class Battle {
  // ... existing properties and methods ...

  // Add quest system to the constructor
  constructor(playerInventory, questSystem) {
    this.playerInventory = playerInventory;
    this.questSystem = questSystem;
  }

  fight(monster, item, questId) {
    // Battle logic and quest progress update
  }
}

// File: components/NPC.js
import { Quest } from './quest.js';

export class NPC {
  // ... existing properties and methods ...

  // Methods to create and offer quests
  createQuest(name, description, objectives, reward) {
    // Logic to create a new quest
  }

  offerQuests(player) {
    // Logic to offer quests to the player
  }

  startQuest(quest, player) {
    // Logic to start a quest and assign it to the player
  }
}

// File: gamedata.js
// Define game data structures for quests, NPCs, and monsters
class Quest {
  // ... constructor and properties ...
}

const questObjectives = {
  // ... quest objectives ...
};

class NPC {
  // ... constructor and properties ...
}

class Monster {
  // ... constructor and properties ...
}

const questLog = {
  // ... quest log structure ...
};

// Export structures for use in other parts of the game
module.exports = {
  Quest,
  NPC,
  Monster,
  questLog,
  questObjectives,
};

// File: breeder.js
import Monster from './monster.js'; 

// Breed monsters with quest-related traits and abilities
export function breedMonsters(monster1, monster2) {
  // ... breeding logic ...
}

// Functions to inherit and mutate traits and abilities
function inheritTraits(parent1, parent2) {
  // ... logic for traits ...
}

function inheritAbilities(parent1, parent2) {
  // ... logic for abilities ...
}

// ... other functions ...

Files used for this task:

Changes on monster.js To extend the `Monster` class to include functionality for participating in quests, we need to consider what attributes and methods a monster would need for such activities. Since the quests can involve searching for items or vanquishing enemies, we might want to add attributes that relate to quest participation, such as a `questStatus` to track whether the monster is on a quest, and methods to engage in quest-related activities. Here's a practical proposal for extending the `Monster` class: 1. Add a `questStatus` attribute to track the monster's current quest status. 2. Add a `currentQuest` attribute to store information about the quest the monster is on. 3. Implement methods for starting a quest, updating quest progress, and completing a quest. 4. Add a method for searching for items, which could involve a random chance to find an item based on the monster's attributes. 5. Add a method for battling as part of a quest, which could use the existing battle mechanics. Here's how the updated `Monster` class might look: ```javascript // Monster class class Monster { constructor(name, health, attack, defense, types) { this.name = name; this.health = health; this.attack = attack; this.defense = defense; this.types = types; this.questStatus = 'idle'; // Possible values: 'idle', 'active', 'completed' this.currentQuest = null; } // Battle mechanics takeDamage(damage) { this.health -= damage; } attackEnemy(enemy) { let damage = this.attack - enemy.defense; enemy.takeDamage(damage); } // Quest mechanics startQuest(quest) { this.questStatus = 'active'; this.currentQuest = quest; } updateQuestProgress(progress) { if (this.questStatus === 'active' && this.currentQuest) { // Update quest progress here // If quest is completed, update questStatus to 'completed' } } completeQuest() { if (this.questStatus === 'completed' && this.currentQuest) { // Reward the monster or player for completing the quest this.questStatus = 'idle'; this.currentQuest = null; } } searchForItems() { if (this.questStatus === 'active' && this.currentQuest) { // Implement item search logic based on monster's attributes and quest requirements } } // Additional methods for quest-related activities can be added here } // Monster type definitions const types = { PLANT: 'Plant', FIRE: 'Fire', WATER: 'Water' } // Export Monster class export default Monster; export { types }; ``` This updated `Monster` class now has the basic structure to participate in quests. The actual implementation of `updateQuestProgress` and `searchForItems` would need to be fleshed out based on the specific game mechanics and quest requirements.
Changes on components/quest.js The `quest.js` file contains the `Quest` class, which is fundamental for implementing the quest system in the game. However, there are several issues and improvements that need to be addressed: 1. **Constructor Typo and Redundancy**: The constructor has a typo and redundant assignments to `this.tasks`. It should only assign each property once. 2. **Tasks and Rewards**: The `tasks` parameter should be an array of objects that define specific tasks to be completed as part of the quest. The `rewards` should also be an object or array that defines what the player will receive upon completing the quest. 3. **Start and Complete Methods**: The `startQuest` and `completeQuest` methods need to be fleshed out. They should include logic for what happens when a quest starts (e.g., updating the game state to reflect that the quest is active) and what happens when a quest is completed (e.g., updating the game state, giving rewards to the player). 4. **Tracking Progress**: There should be a way to track the progress of the quest. This could be done by adding a property to the `Quest` class that keeps track of the current state of each task. 5. **Integration with Monsters**: Since quests will involve using monsters, there needs to be a way to link monsters to quests. This could be through a method in the `Quest` class that allows a monster to be assigned to a task. Here's a revised version of the `Quest` class with these points in mind: ```javascript // components/quest.js export class Quest { constructor(name, difficulty, rewards, tasks = []) { this.name = name; this.difficulty = difficulty; this.rewards = rewards; this.tasks = tasks; // Should be an array of task objects this.isActive = false; // Track if the quest is active this.isCompleted = false; // Track if the quest is completed } startQuest() { // Update game state to reflect that the quest is active this.isActive = true; console.log('Starting the quest: ' + this.name); console.log('Tasks to complete: ', this.tasks); // Additional logic to assign monsters to tasks, if necessary } updateProgress(taskId, progress) { // Update the progress of a specific task const task = this.tasks.find(t => t.id === taskId); if (task) { task.progress = progress; // Check if all tasks are completed this.checkCompletion(); } } checkCompletion() { // Check if all tasks are completed const allTasksCompleted = this.tasks.every(task => task.progress === 'completed'); if (allTasksCompleted) { this.completeQuest(); } } completeQuest() { // Update game state to reflect that the quest is completed this.isCompleted = true; console.log('Completing the quest: ' + this.name); console.log('Claiming rewards: ', this.rewards); // Logic to give rewards to the player } } ``` This revised `Quest` class now includes methods for starting a quest, updating progress, checking for completion, and completing the quest. It also tracks whether the quest is active or completed. The next step would be to integrate this class with the rest of the game, ensuring that quests can be assigned to monsters and that rewards are properly given to the player.
Changes on screens/battling.js To ensure that the battling system can be triggered from a quest context and that quest progress is updated upon completion of a battle, we need to modify `screens/battling.js` to integrate with the quest system. Here's a practical proposal for how to solve this task: 1. **Integrate Quest Progress Tracking:** - Import the quest system module to track the progress of the quest. - Add a method to update the quest status after a battle is completed. 2. **Battle Outcome Logic:** - Implement logic to determine the outcome of the battle (win/lose). - Based on the outcome, update the quest progress (e.g., if the quest was to defeat a certain monster, mark it as completed). 3. **Battle Trigger from Quest:** - Allow a battle to be initiated as part of a quest, which means passing the relevant quest details to the `Battle` class. 4. **Error Handling and Validation:** - Ensure that the item used in the battle is validated before the fight begins. - Handle cases where the battle cannot be initiated due to quest conditions not being met. Here's an example of how the code might be modified: ```javascript import { Inventory, Item } from '../inventory.js'; import QuestSystem from '../quest/QuestSystem.js'; // Import the quest system class Battle { constructor(playerInventory, questSystem) { this.playerInventory = playerInventory; this.questSystem = questSystem; // Add the quest system to the constructor } fight(monster, item, questId) { if (!this.playerInventory.items.includes(item)) { throw new Error('Item not in inventory'); } this.playerInventory.useItem(item); // Logic for fighting the monster goes here // For example, let's say the outcome is determined by a simple random chance for now const outcome = Math.random() > 0.5 ? 'win' : 'lose'; if (outcome === 'win') { // Update the quest progress if the battle was part of a quest if (questId) { this.questSystem.completeQuestStep(questId, monster); } // Additional logic for winning the battle } else { // Logic for losing the battle } } } export default Battle; ``` In this example, we've added a `questSystem` parameter to the `Battle` class constructor and a `questId` parameter to the `fight` method. This allows the battle to be associated with a specific quest. After the battle, the quest system is updated based on the outcome. Please note that the actual implementation of the quest system and the battle outcome logic will depend on the rest of your game's codebase. The `QuestSystem` class and its `completeQuestStep` method are placeholders for whatever actual quest tracking implementation you have in your game.
Changes on components/NPC.js To modify the `NPC` class to include the ability for the village elder to assign quests to the player, we need to ensure that the `NPC` class can create a quest and assign it to the player. Here's a practical proposal to implement this functionality: 1. Add a method to the `NPC` class that allows the creation of a quest. This method should be able to define the quest's objectives, rewards, and any other relevant details. 2. Ensure that the `startQuest` method properly initializes the quest and assigns it to the player. This may involve updating the player's quest log or active quests. 3. Add a method to check if the player's monsters meet the requirements for a quest. This could involve checking the monsters' levels, types, or other attributes. 4. Implement a dialogue system that allows the NPC to communicate with the player about available quests, quest progress, and completion. Here's an example of how the `NPC` class could be updated: ```javascript import { Quest } from './quest.js'; export class NPC { constructor(name, role, dialogue) { this.name = name; this.role = role; this.dialogue = dialogue; this.availableQuests = []; // Store available quests for this NPC } createQuest(name, description, objectives, reward) { const newQuest = new Quest(name, description, objectives, reward); this.availableQuests.push(newQuest); } offerQuests(player) { // Communicate with the player and offer available quests this.availableQuests.forEach(quest => { if (player.meetsQuestRequirements(quest)) { // Offer the quest to the player console.log(`${this.name}: ${quest.description}`); // The player can then accept the quest, which would call startQuest } }); } startQuest(quest, player) { if (quest instanceof Quest && this.availableQuests.includes(quest)) { quest.startQuest(); player.acceptQuest(quest); // Assuming the player has a method to accept quests this.availableQuests = this.availableQuests.filter(q => q !== quest); // Remove the quest from available quests } } sellItem(item, player) { if (player.coins >= item.cost) { player.coins -= item.cost; player.inventory.push(item); } } } ``` In this example, the `NPC` class now has the ability to create quests and offer them to the player. The `offerQuests` method would be used to communicate available quests to the player, and the `startQuest` method has been updated to also remove the quest from the available quests once it's started. Please note that this is a high-level proposal and assumes the existence of certain methods and properties on the `Quest` and `Player` classes, such as `meetsQuestRequirements` and `acceptQuest`. These would need to be implemented in their respective classes to fully support the quest system.
Changes on gamedata.js Since the `gamedata.js` file is currently empty, we need to create a structure that will hold all the necessary data for the game, including the new quest mechanics. Here's a practical proposal for implementing the quest-related data within `gamedata.js`: 1. Define the Quest Data Structure: - Create a `Quest` class or object structure that includes properties such as `id`, `title`, `description`, `objective`, `reward`, `status`, and any other relevant information. - Define different types of objectives, such as `searchForItem` or `vanquishEnemies`, and what data they need (e.g., item to search for, enemy type, and count). 2. Define the NPC Data Structure: - Since NPCs will be assigning quests, include a list of available quests for each NPC, particularly the village elder. 3. Define the Monster Data Structure: - Ensure that monsters have properties that can affect quest outcomes, such as `strength`, `speed`, `intelligence`, etc. 4. Create a Quest Log: - Implement a quest log that keeps track of all active, completed, and available quests for the player. 5. Define Rewards and Progress Tracking: - Determine how rewards are structured and how quest progress is tracked and updated. 6. Integrate with Other Game Systems: - Ensure that the quest data is accessible and modifiable by other components of the game, such as `monster.js`, `breeder.js`, and `battling.js`. Here's a basic example of how the `gamedata.js` file might start to take shape: ```javascript // Quest structure class Quest { constructor(id, title, description, objective, reward, status = 'available') { this.id = id; this.title = title; this.description = description; this.objective = objective; // This could be an object itself, depending on complexity this.reward = reward; this.status = status; // e.g., 'available', 'active', 'completed' } } // Sample quest objectives const questObjectives = { searchForItem: (item, quantity) => ({ type: 'searchForItem', item, quantity }), vanquishEnemies: (enemyType, count) => ({ type: 'vanquishEnemies', enemyType, count }), }; // NPC structure class NPC { constructor(id, name, quests = []) { this.id = id; this.name = name; this.quests = quests; } } // Monster structure (simplified) class Monster { constructor(id, name, traits) { this.id = id; this.name = name; this.traits = traits; // e.g., { strength: 10, speed: 5, intelligence: 7 } } } // Quest log const questLog = { activeQuests: [], completedQuests: [], availableQuests: [], }; // Example of adding a quest to an NPC const villageElder = new NPC(1, 'Village Elder'); const findHerbsQuest = new Quest( 1, 'Find Healing Herbs', 'Collect 10 healing herbs for the village apothecary.', questObjectives.searchForItem('Healing Herb', 10), { experience: 100, items: ['Potion'] } ); villageElder.quests.push(findHerbsQuest); // Export structures for use in other parts of the game module.exports = { Quest, NPC, Monster, questLog, questObjectives, }; ``` This is a starting point for `gamedata.js`. As development progresses, you'll need to refine these structures, add methods for manipulating the data, and ensure that they integrate seamlessly with the rest of the game's codebase.
Changes on breeder.js To ensure that the breeding system in `breeder.js` can produce monsters with the traits and abilities necessary for completing quests, we need to consider the following modifications: 1. **Trait and Ability Inheritance**: The current breeding system only considers health, attack, and types. We need to extend this to include traits and abilities that could be relevant for quests. For example, if a quest requires a monster to search for items, it might need a 'search' ability or a 'keen sense' trait. 2. **Quest-Specific Traits**: Introduce new traits or abilities that are specifically designed for quest activities, such as 'tracking', 'stealth', or 'strength'. These should be inheritable and possibly subject to mutation during breeding. 3. **Balancing**: Ensure that the breeding system maintains balance in the game. Introducing powerful quest-related traits and abilities should not make the monsters overpowered for other aspects of the game, such as battling. 4. **Mutation Rate and Range**: Adjust the mutation rate and range for health and attack, and introduce mutation possibilities for the new traits and abilities. This will add variety and unpredictability to the breeding process, making it more engaging. 5. **Cooldown Management**: Consider whether the cooldown for breeding should be adjusted based on the complexity of the traits and abilities being inherited. More complex or powerful traits might warrant a longer cooldown period. 6. **Feedback to Players**: Provide feedback to players on the outcome of the breeding process, including any new traits and abilities the offspring has inherited. This will help players make informed decisions about which monsters to breed for specific quests. Here's a practical proposal for the `breeder.js` file, incorporating some of these ideas: ```javascript // Import Monster class import Monster from './monster.js'; // Breed cooldown timer let lastBreedTime = 0; const breedCooldown = 30; // seconds // Breed monsters export function breedMonsters(monster1, monster2) { // Enforce cooldown const now = new Date().getTime(); if (now - lastBreedTime < breedCooldown*1000) { console.log('Breeding too fast! Please wait.'); return; } // Inherit primary type from parent 1 let type1 = monster1.types[0]; // Secondary type from parent 2 let type2 = monster2.types[Math.floor(Math.random() * monster2.types.length)]; // Generate random mutations for health and attack let healthMutation = Math.floor(Math.random() * 20) - 10; let attackMutation = Math.floor(Math.random() * 20) - 10; // Inherit and mutate traits and abilities for quests let inheritedTraits = inheritTraits(monster1, monster2); let inheritedAbilities = inheritAbilities(monster1, monster2); // Create child monster let child = new Monster( generateName(monster1, monster2), (monster1.health + monster2.health) / 2 + healthMutation, (monster1.attack + monster2.attack) / 2 + attackMutation, [type1, type2], // inherit types inheritedTraits, inheritedAbilities ); // Set cooldown lastBreedTime = now; // Return child return child; } // Function to inherit and possibly mutate traits function inheritTraits(parent1, parent2) { // Logic to combine and mutate traits from both parents // ... return combinedTraits; } // Function to inherit and possibly mutate abilities function inheritAbilities(parent1, parent2) { // Logic to combine and mutate abilities from both parents // ... return combinedAbilities; } // Other functions... ``` In this proposal, I've added placeholders for `inheritTraits` and `inheritAbilities` functions, which would need to be implemented to handle the logic of combining and mutating traits and abilities from both parents. The actual implementation would depend on the structure of the `Monster` class and how traits and abilities are represented within it. This proposal aims to extend the breeding system to support the quest mechanics as described in the task. Further refinement and testing would be necessary to ensure that the system is balanced and integrates well with the rest of the game.
