Targetable Abilities
Custom abilities can be made targetable by implementing the IAbilityTargetable interface. You can determine the target of the special ability (for example, the closest agent), and a special ability indicator will be displayed over it. Then you'll be able to access the determined target through the CurrentTarget property.
Making abilities targetable
Just implement the IAbilityTargetable interface in your ability's class:
/MyAwesomeProject/MyTargetableAbility.cs
public class MyTargetableAbility : CustomAbility, IAbilityTargetable{ public PlayfieldObject FindTarget() { /* ... */ }}FindTarget determines the closest (or the most compatible/applicable) target, that the ability can be used on right now. If the ability cannot be used right now, you should return null. Then, you can use CurrentTarget in any of the methods:
/MyAwesomeProject/MyTargetableAbility.cs
public override void OnPressed() { if (CurrentTarget is null) { gc.audioHandler.Play(Owner, "CantDo"); return; } /* ... */ }Examples
