Hello everyone.
I’m making an FPS game and I recently added the function in the game that allows the player to switch between weapons. But I keep getting one weird problem that I can’t seem to solve… When I switch to the next weapon I disable the current weapon GameObject and I enable the new one, but the problem is that if I switch to the new weapon while the animation is currently playing (e.g. ‘Attack’ animation or ‘Ready’ animation) I get weird position / rotation problems… I thinks it’s a bug in unity, but I’m not sure… I included the gif file of the problem and I also provided the weapon switch script.
Can someone help me with this? Any help is really appreciated! 
Thank you!
