it happen after the swift3 update some of my levels is like my player falling down from the ground tile .
its like my 1player has no physics body and in some level its ok?
and when i copy past coins its don’t display on the screen .
Well a copy and paste issue with the Scene Editor won’t be an issue with the kit, thats something with Xcode. And I’ve seen glitches like that before, where sometimes its just best to drag in a new SKSpriteNode and copy and paste from that (instead of nodes from other scene files).
Feel free to turn physics boundaries on and take a video-capture of whats happening. Might tell me more than describing it.
