UE3 - UDK Attempting to get a team system set up for custom AI and Projectiles

[LeviGratton]

Our game is an attempt to make a sort of player vs computer, team vs team tower defense. Each side, one player, one AI, has a series of pawns on paths that are meant to kill each other.

Each side can also spawn towers that fire projectiles.

Our current problem is that everything can kill everything from the same actor factories. We're trying to figure out a way to create a team system for the AI to not kill each other on one team, but kill everyone else on the other team through both projectiles and melee combat.

Does anyone have any advice, tutorials, videos, or sample scripts?

This is a first year college game project, so assume we're all at the rank of beginner please.

It's really hard to say without any specifics. I think you must already know this, so if this is too basic, upload some code and we'll see what needs to change... But at the most general level you'll need to have two things:

1. In whatever class your soldiers or whatever are, add a variable that stores what team they're on. Set that variable when the soldier gets created.

2. In whatever function selects a target, check to see whether that actor is on the same team. It might look something like this:

if(target.team != myteam) attack(target); else selectNewTarget();

@LeviGratton: Which classes you're extending?

To clarify some information.

We've set up triggers in front of each tower, and when a bot enters the trigger it activates a spawn projectile that damages any bot that enters the trigger, regardless of team.

so we're trying to make one set of spawned bots on one team immune to their own team's spawned projectiles. We have custom projectile scripts

Is there a way to make our custom bots immune to either the projectile type or a damage type

class CookieRocket extends UTProjectile;

simulated function PostBeginPlay()
{
	// force ambient sound if not vehicle game mode
	bImportantAmbientSound = !WorldInfo.bDropDetail;
	Super.PostBeginPlay();
}

The best place to do it it's function ReduceDamage in YourGameInfo or TakeDamage In YourPawn. Do the check on TeamIndex by calling OnSameTeam, but you need to override ScriptGetTeamNum in each - YourPawn and YourProjectile, because native code is looking for information about TeamInfo (which you should use instead of messing with coustom team info system...).
