Collision box for AS3 + papervision3d + jiglib

I'm trying t开发者_运维问答o recreate the "tutorial" explained on the site below. It's 5 dices bouncing around on the scene. But i'm stuck at the very beginning :)

papervision3d-jiglib-dice-demo

My problem is the bounding box. I want to create a box with a floor and 4 walls based on the size of the stage. I can get it the right size using zoom/focus on the camera. But the problem is the dices go through it.

How can i build 4 walls and make sure a dice doesnt go through it when i apply forces to it?

I tried the solution in the following source, but somehow the dices keep going through :(

Anybody knows how to do it? Or a better way to keep the dices on screen?

I solved the problem. Just to share with others who want to try the same:

• Set camera zoom = 2
• Set camera focus = distance / zoom

• // now the scene width and height match the actual size of the stage.

• add the planes for all sides and make sure you make the segments smaller then the dice size. (EG: dice size = 30; stage width = 300; segments = stage width/ dice size = 10).

• make sure you ceil the results because segments require int
• Ofcourse you can make it larger, but then it will be harder to render.

• I made the height of the planes a little smaller then twice the dice size to make sure they never get on top of eachother.

• And finally add a ceiling by placing another plane with small segments on top of the other planes
