Hello,
I have a Scene running this way:
[[CCDirector sharedDirector] runWithScene: [LoadingScene scene]];

where scene is:
```
+(id) scene
{
	// 'scene' is an autorelease object.
	CCScene *scene = [CCScene node];

	// 'layer' is an autorelease object.
	LoadingScene *layer = [LoadingScene node];

	// add layer as a child to scene
	[scene addChild: layer];

	// return the scene
	return scene;
}
```
But when I do
[[CCDirector sharedDirector] replaceScene:[MainMenuScene scene]];

I get this error:
*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSMutableArray replaceObjectAtIndex:withObject:]: index 4294967295 beyond bounds for empty array'

Can anyone help me please?

Use runWithScene only the 1st time. it is the "bootstrap" scene. Don't call runWithScene again.
Use replaceScene to replace an already running scene.
You can also use pushScene

That is what is happening. For the first scene (LoadingScene) I use runWithScene and for the nextScene I use replaceScene. I don't use pushScene to save memory but if I use it it gives-me the same error.

Reonarudo,

Looks like you are calling replace scene in the init of that first scene. Maybe try calling your replace scene from onEnter of your LoadingScene.

Thank you very much!

That solved it.

Mark, thanks very much for your post. I couldn't figure out why my loading scene wasn't appearing between two other scenes and by creating and replacing the last scene in my loading scene onEnter function, it worked.

I actually didn't have a forum account but signed up just to thank you!
