Retrieving a variable from a my script and storing it in FSM variable

[DerDicke]

I wrote this to retrieve a variable from my script and store it in FSM variable. It seems to work like a charm, but i would like to know if there might be issues or if there is a better way to do it.

Code: [Select]

#if PLAYMAKER
using HutongGames.PlayMaker;
using HutongGames.PlayMakerEditor;

namespace MagicAI
{
    [ActionCategory(ActionCategory.ScriptControl)]
    [HutongGames.PlayMaker.Tooltip("Gets the GameObj from AI's Blackboard and sets it as variable in FSM. AI must be parent to this FSM")]
    public class GetMagicAIGameObjFromBlackboard : FsmStateAction
    {

        [HutongGames.PlayMaker.Tooltip("Variable to set to variable from MagicAI Blackboard")]
        //public FsmVariable variableToSet;
        public FsmVar variableToSet;
        public string keyInBlackboard;
        private NamedVariable targetVariable;

        public override void OnEnter()
        {
            base.OnEnter();

            AI ai = FindAI();
            if (ai)
            {
                Blackboard bb= ai.GetComponent<Blackboard>();
                if (bb == null)
                {
                    Debug.LogWarning("MagicAI: Play Maker: No Blackboard found! FSM is " + this.Fsm.Name);
                }
                else
                {
                    GameObject go = bb.Get(keyInBlackboard);
                    if (go == null)
                    {
                        Debug.LogWarning("MagicAI: Play Maker: GameObj '" + keyInBlackboard + "'retrieved from to Blackboard is null! FSM is " + this.Fsm.Name);
                    }
                    else
                    {
                        targetVariable = Fsm.Variables.GetVariable(variableToSet.variableName);
                        variableToSet.Type = targetVariable.VariableType;
                        variableToSet.gameObjectValue = go;
                        variableToSet.ApplyValueTo(targetVariable);
                    }


                }
            }

            Finish();
        }


        AI FindAI()
        {
            AI ai = this.Fsm.GameObject.GetComponentInParent<AI>();
            if (ai) return ai;
            Debug.LogWarning("MagicAI: Play Maker: No AI on parent found on " + this.Fsm.Name);

            return null;
         }


    }
}
