Activating Gravity "bug"

In my game, the user can place pieces and then hit start, which activates gravity. If the user places a piece right on top of the ground or object, the piece goes down into the ground a little bit then pops back up. If the ground is only say 5px thick, the piece will actually go through it, which is not supposed to happen. Is there any way to fix this? If you need more description, I can probably post a video.

For any fast-moving object, you’ll probably want to set the “isBullet” property to true, which forces continuous collision detection (so it will be able to detect collisions at their actual positions, rather than going to far). [import]uid: 9371 topic_id: 3938 reply_id: 11986[/import]

Thanks, dweezil! I’ll try that once I get back to a mac. [import]uid: 8782 topic_id: 3938 reply_id: 11988[/import]

It still doesn’t work, surprisingly. I’ll post a video here if I get some time. Anyone have any other ideas? [import]uid: 8782 topic_id: 3938 reply_id: 12037[/import]

don’t let them place the piece there then! [import]uid: 6645 topic_id: 3938 reply_id: 12123[/import]
