Thanks buddy, I will test your suggestion
Thanks for the catch, I replicated the same situation you mentioned and in fact the Robot X stays outside of the screen, laughing and trying to shoot.
This happens because this character walks in a straight line only. Due to the distance, he will try to shoot but since certain projectiles are removed when outside of the screen, if players or cpu partners keep the same position at the screen edge, he will enter into a shoot/laugh loop.
Based on your image, Abadede is trying to chase him, causing the loop. In situations like that at the cpu partner mode, I suggest using the "call" button, this way you can stop the cpu partner attacks temporarily.
I will improve the Robot X behaviours to avoid this kind of situation.
