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