iTween Paths : Element with the same key already exists in the dictionary
I have a menu which is a duplicate of my main game scene with a flythrough camera.
I have a main game scene where I have several objects which follow iTweenPaths.
I have a duplicate of this scene, just without the player, with a camera flythrough for the main menu.
When the menu scene loads the game scene I get the following:
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/Plugins/iTweenPath.cs:17)
I understand the error, keys are unique and the paths are already added within the menu scene but I don't know how to correct it?
Change blah.Add(key, value) to blah[key] = value;
The former throws an exception when adding a duplicate key, while the latter doesn't.
Have you tried the most recent iTweenPath from my blog? If so can you send me a project that I can take a look at?
I added these lines before line 17 and I no longer get that error, Im moving the path nodes around in my script, and the changes were not taking effect when I loaded the scene, then left, and loaded the scene again. The 2 lines below are a quick fix, pixelplacement maybe you want to look into this?
if(paths.ContainsKey(pathName.ToLower())) paths.Clear();
paths.Add(pathName.ToLower(), this);
Mike 3 has it right in general terms above.
The actual change to iTweenPath.cs that I made is:
void OnEnable(){
if(!paths.ContainsKey(pathName)){
//paths.Add(pathName.ToLower(), this);
paths[pathName.ToLower()] = this; // updated from answers.unity3d.com/questions/49137
}
}
As you can see I commented out the original line and added the replacement line: paths[pathName.ToLower()] = this;
This fix works my situation when I was instantiating the same prefab from a spawn point multiple times. Hope this makes it easier for all.

Seems like this issue is still around in iTween. Thank you for a great and easy solution!
Oh my god thanks guys so much for the easy fix.... Much appreciated...
