Make (animated) sprite invisible?

[Napoleon]

I can change the z-axis to somewhere behind the 2D scene. But what is the proper way to do this?

I have a projectile and it hits something, so I disable it's collision and want it to become invisible while the explosion sfx is playing. After that it is automatically destroyed.

You're just mixing behaviours here - the explosion should really be separate to the projectile, but if  you really want to do it this way you can disable the renderer on the object.

You are right. It's bad design. I should use a separate object for the explosion and clean up the projectile.
