[Custom Decision Script] Get Target Current Health %

[cursedereaper]

Hey,

I wrote the custome decision "Get current Targets Health" which could be used to switch into a more agressive state like less blocking and more attacking if the target has little Health. And this Thread is only to share this with everyone.
I hope you like it.

using UnityEngine;

namespace Invector.vCharacterController.AI.FSMBehaviour
{
   public class AICheckTargetHealth : vStateDecision
   {
       public override string defaultName
       {
           get
           {
               return "Check Target Health";
           }
       }

       public enum vCheckValue
       {
           Equals, Less, Greater, NoEqual
       }

       public vCheckValue checkValue = vCheckValue.NoEqual;
       public float value;

       public override bool Decide(vIFSMBehaviourController fsmBehaviour)
       {
           return CheckValue(fsmBehaviour);
       }

       protected virtual bool CheckValue(vIFSMBehaviourController fsmBehaviour)
       {
           if (fsmBehaviour == null) return false;

           float health = fsmBehaviour.aiController.currentTarget.currentHealth;

           switch (checkValue)
           {
               case vCheckValue.Equals:
                   return health == value;
               case vCheckValue.Less:
                   return health < value;
               case vCheckValue.Greater:
                   return health > value;
               case vCheckValue.NoEqual:
                   return health != value;
           }

           return false;
       }
   }
}

I also want to include the get current target Stamina as well because it could be something one could use to switch into a more agressiv behavior or that an Enemy with low ammo will only shoot a target with low stamina (or throw a granate on an target with low stamina via trigger events).

And a small note: It is quite easy to write the decision that only refer to parts from invector scripts (PS: I'm actually an Artist XD). I still have problems to include bools of script my programmer made.

Thank you, cursedereaper, this is something I always use since I originally saw this post.

If it makes sense, it could be nice to consider putting these decisions into the next FSM AI update (v1.2) Invector.

I believe there's currently only the option to check the AI controller's own health.

This could be nice for dynamically changing game difficulty (if the player is injured, shoot less at the player), making blind AI that 'smells'/detects injured characters (zombies/monsters), or friendly AI that heals a character if their health is low.

Awesome, thanks for sharing!
