How do I change animation to a bullet object?

Hi.

I'm trying to make an explosion to a bullet whenever it hits with a wall (Solid Tilemap in my case).

I really don't understand why but the bullet never changes animation. I can do everything I want. Stop timescale, disable, etc etc but it jut won't change animation.

Is this supposed to be this way on C2? Or am I doing something wrong?

Only event not showing is the turret spawning bullet, nothing important.

Tried with collision, overlapping, overlapping offset. None works for the animation but they do for everything else.

Found out something weird... I used a set frame before the animation and I set frame 5 (my animatio only has 4 frames for default and 3 for the explosion one). Don't know why, but now it displays the animation.

If I set the frame to an existing frame, it doesnt work. I have to make up a fake frame in order to work.

Someone could explain this?

Why so difficult? Why use 'wait'?
