Zeds hostile to AI problem

[f3cuk]

Okay so i'm currently testing the Testbranch and i noticed a problem with making Zeds hostile to AI. Not only is the AI attacking Zombies now, it's also attacking stuff like player bases.

Im guessing CIVILLIAN is used for more then just the zombies. Removed it for now.

From another ai script

// Create the Centers for AI
ZFM_GROUP_EAST = createCenter east;
ZFM_GROUP_WEST = createCenter west;
ZFM_GROUP_CIVILIAN = createCenter civilian;
ZFM_GROUP_RESISTANCE = createCenter resistance; // Vive Le Resistance!

// unfriendly AI bandits
EAST setFriend [WEST, 0];
EAST setFriend [RESISTANCE, 0];

// Players
WEST setFriend [EAST, 0];
WEST setFriend [RESISTANCE, 0];

// friendly AI
RESISTANCE setFriend [EAST, 0];
RESISTANCE setFriend [WEST, 0];

Ehm that does nothing with zombies i think (not sure). Just create a few different groups to make stuff more complicated :P

[nerdalertdk]

friendly AI can be used for the Hero missions maybe ?

[f3cuk]

Not sure, but i think ARMA 2 allows for a total of 4 sides.

WEST [BLUFOR] = Used for all player EAST [OPFOR] = Used for all AI CIVILIAN = Used for all zeds and inanimate mission editor placed objects and i think Headless Clients RESISTANCE = Not sure if this one is used right now

We could switch hero units into the resistance slot so we can set different global settings like type of stance. Right now AI is very aggressive and shoots on sight. We could change that to only return fire with Hero missions. Which i think might even be a better method cause we dont have to worry about heroes gone rogue and killing their own kind cause they will return fire. Saves us a lot of time and trouble on that part.

Furthermore "real" bandits are probably always aggressive and wont trust anyone. So its not bad that they kill on sight.

When it testing i noticed the AI did not attack the spawned in barracks etc. Maybe its got to do with spawn order, i spawned in the tanktraps after the AI, now trying to spawn them in before, they might not treat them hostile then.

I think we need to find another way to make them hostile towards eachother. Don't believe we can make it work like this.

[nerdalertdk]

Think hero missions are doable if we can move the AI behavior to the mission it self

Hero = combat mode "white" Bandit = combat mode "red"

Agree. Seems like the way to do it. Will start working on this when 2.0.0 is released.

Vehicles (objects) have also a faction/side, most of them should be civillian. Units created as agents are always civillian.

I do it like DZAI, i reduce rating for Zombies in range of the AI-units on client side (of owner side), that works great to let the AI attack the Zombies.

[f3cuk]

How does this reducing of rating work actually? Have you got some code examples?

[rockeumel]

i use a publicvariableeventhandler, compiled in the mission:

"RHAI_changeRating" addPublicVariableEventHandler { _targets = (_this select 1) select 0; _rating = (_this select 1) select 1; { if (local _x) then { if(rating _x > _rating) then { _x addRating _rating; }; }; } forEach _targets; };

and then run on serverside a while loop per group every 15 seconds, that looks for zombies in a 100m range around the AI, and call:

_unitsAlive = {alive _x} count (units _this);

while {_unitsAlive > 0} do {
    _nearEntities = (leader _this) nearEntities ["zZombie_Base",_range];
    {
        if (local _x) then {
            if(rating _x > -30000) then {
                _x addrating -30000;
            };
        } else {
            RHAI_changeRating = [[_x],(-30000)];
            (owner _x) publicVariableClient "RHAI_changeRating";
        };
    } foreach _nearEntities;
    sleep 15;
    _unitsAlive = {alive _x} count (units _this);
};

[f3cuk]

That is actually pretty smart. Didnt know there was something like addrating in ARMA :) Thanks for the example!

credits goes to buttface maker of the DZAI

i used something like that by myself, but it is realy effective if you set the rating on the owner side of the zombie, the ai react faster against zombies

[nerdalertdk]

can we add bicycle in there ? _nearEntities = (leader _this) nearEntities ["zZombie_Base","Bicycle",_range];

AI don't detect Bicycle by default.

[rockeumel]

you shouldn't set ratings for player, that could result in bad effects

[nerdalertdk]

technicel its not a player ;)

but right now you can bicycle past all AI since the bicycle is "invisble" to them

[rockeumel]

Hmm, i spawned 2 different bikes on my server and drive by AI, and they shot me realy quick
