After switch form html5 to native collisions are not working

How to fix that?

The only difference between HTML5 and native collision handlers is on the pixel-perfect collision detection, if you are using this condition in HTML5 (Sprite >> Collision) try to switch to mask collision in native (All objects >> Collision), this way they will have the same handling.

If it isn’t your problem, we could take a look (event’s screenshot, example project) :slight_smile:

ok they are working but only when i compile them, in preview they don’t work.
