Hi Everyone,
Just a simple addition to allow for watching a boolean change from another fsm. Very handy to avoid storing duplicate information across fsm.
// (c) Copyright HutongGames, LLC 2010-2011. All rights reserved.

// this is a combination of BoolChanged and GetFsmBool since I don't want the extras steps required otherwise.
// I also don't feel like saving a variable for every single check from other fsm, I want to avoid redundance sometimes.
using UnityEngine;
namespace HutongGames.PlayMaker.Actions
{
[ActionCategory(ActionCategory.Logic)]
[Tooltip("Tests if the value of a Bool variable from another FSM has changed. Use this to send an event on change")]
public class FsmBoolChanged : FsmStateAction
{
[RequiredField]
public FsmOwnerDefault gameObject;
[UIHint(UIHint.FsmName)]
[Tooltip("Optional name of FSM on Game Object")]
public FsmString fsmName;
[RequiredField]
[UIHint(UIHint.FsmBool)]
public FsmString variableName;
public FsmEvent isTrue;
public FsmEvent isFalse;
bool currentValue;
bool previousValue;
GameObject goLastFrame;
PlayMakerFSM fsm;
public override void Reset()
{
gameObject = null;
fsmName = "";
isTrue = null;
isFalse = null;
}
public override void OnEnter()
{
DoGetFsmBool();
previousValue = currentValue;
}
public override void OnUpdate()
{
DoGetFsmBool();
if (currentValue != previousValue)
{
if (currentValue){
Fsm.Event(isTrue);
}else{
Fsm.Event(isFalse);
}
}
}
void DoGetFsmBool()
{
GameObject go = Fsm.GetOwnerDefaultTarget(gameObject);
if (go == null) return;
// only get the fsm component if go has changed
if (go != goLastFrame)
{
goLastFrame = go;
fsm = ActionHelpers.GetGameObjectFsm(go, fsmName.Value);
}
if (fsm == null) return;
FsmBool fsmBool = fsm.FsmVariables.GetFsmBool(variableName.Value);
if (fsmBool == null) return;
currentValue = fsmBool.Value;
}
}
}
Bye,
Jean
