In my game have 2 actions, Roll (Dodge) and Attack, and if i interupt Roll animation, with attack, i cant play Roll Animation. Who knows why this happend
It depends on your implementation. Can you attach screenshots?
I found a solution to the problem, from Play montage from on Interrapped you need to output to Do Once, But I have one more question how to make the animation impossible to interrupt
put a branch before animation, connect True output to animation, then assign a bool to it, and set it to true or false whenever you want to block or unblock the animation.
