How do I "instantiate" a path with iTween?

Questions & Answers

I’m building a towerdefence where I instantiate lots of npc that follow a same path, but then I get the following error when I instantiate the second npc:

    ArgumentException: An element with the same key already exists in the dictionary.
System.Collections.Generic.Dictionary`2[System.String,iTweenPath].Add (System.String key, .iTweenPath value)
iTweenPath.OnEnable () (at Assets/Pixelplacement/iTweenPath/iTweenPath.cs:39)
UnityEngine.Object:Instantiate(Object)
script_01_BeachTutorial:AddEnemy(GameObject, Vector3, String, Single) (at Assets/Scripts/Controls/Levels/script_01_BeachTutorial.cs:70)
script_01_BeachTutorial:Update() (at Assets/Scripts/Controls/Levels/script_01_BeachTutorial.cs:36)

And this is what I’m using to instantiate a new enemy:

void AddEnemy(GameObject EnemyType, Vector3 EnemyPosition, string PathToFollow, float PathTime)
	{
		
		GameObject Enemy = (GameObject)Instantiate(EnemyType);
		script_EnemyWaypointer Script = Enemy.GetComponent<script_EnemyWaypointer>();
		
		Enemy.transform.position = EnemyPosition;
		
		Script.PathToFollow = PathToFollow;
		Script.PathTime = PathTime;
		Script.UseTimeAndIgnoreSpeed = true;
		Script.WayPointTween();
	}

ps: Sorry about the bold, it’s just highlight text from code :slight_smile:

Thanks in advance ^^

SOLVED

It is caused by a bug in the iTweenPath.cs code (Thanks to NCarter)

LOCATION:

line 37: CORRECT VERSION

void OnEnable()
{
    string lowerPathName = pathName.ToLower();
    if (!paths.ContainsKey(lowerPathName))
    {
        paths.Add(lowerPathName, this);
	}
}

But do be careful. If you have two or more paths with the same name active the OnComplete will only be called once.
