Crash using latest
Edit: I found the solution - I had two tweens set up to run on the same object (opening and closing a menu) and hadn’t implemented a check to see whether one had finished before trying to run the other. (Knew it would be a dumb mistake!) That left me with two tweens trying to access the same AitAux object at once which crashed the program.
Ok, this is probably a newbie mistake somewhere, but I’m getting constant crashes trying to use the latest iTween on Unreal 4.15 to tween a vector2D to change a UMG widget slot size. I’m working entirely in Blueprint for this widget but the project is mixed BP and code.
The issue is that I can set up the Blueprint, have everything working nicely, and then when I close and re-open the BP I get an Access Violation crash pointing at iTween.cpp line 88:
aux = (AiTAux*)(GetWorldLocal()->SpawnActor<AiTAux>(AiTAux::StaticClass(), params));
I recreated the BP and it looks like this:
Can anyone point out where I’m going wrong?
