Hi all, Im new here.
Im followed the “Hello animation tutorial” with a model that I created, but its giving me an error when I add a listener to the control
here is the line code:
[java]control.addListener(this);[/java]
The code is practically the same of “Hello Animation”. Could anyone tell me what it must be?
Here is the error:
SEVERE: Uncaught exception thrown in Thread[LWJGL Renderer Thread,5,main]
