falling through ground

chrsmys

I am having trouble with the collision because sometimes on the ground just in random places my character falls through... Does anyone have any ideas?

how are you controlling the character? Constraining to touch perhaps?

I've noticed similar hit-miss behavior with the collision system, any ideas anyone?

I've notices gapping too. Reducing the complexity of the ground/walls may help (i.e. bigger/longer pieces instead of multiple little blocks). Also, ensuring the pieces are aligned properly is a good idea (I've seen some sloppy walling/flooring on a few test projects). It could be you haven't implemented the concept of wall/floor the best it could be (there are some demo projects that seem pretty solid so take a peek at those). Also, if using round collision regions for any walls/floors (i.e. a row of barrels, gears, etc.), you will probably want some overlap or switch back to square/rectangular collision regions if they don't really move/roll anywhere.

Just some thoughts without seeing any examples of your particular issue.

i've seen this a few times, make sure the 2 actors are set to collide, you could try playing with the restitution, the other thing i noticed was if my invisible barrier walls were over lapping. i.e. take your 480 x 320 screen, i had walls around the 4 sides of that, where i overlapped the walls in the corners, if you hit them the actor would pass through. I then left about 1mm gap between the walls so the actor could not fit through it and that also stopped the actor going through the walls

I had this problem too, like beefy said, check and make sure your actors are both set to collide including your wall

Also, if there's gravity in a scene, make sure the ground or wall actor can't fall , and that it's set to non-moveable
