3D Wall Collision Detection ?

[mastermax]

Hi;

Today, I started making a simple FPS like 3D game engine using flash 10's features. You can see it: http://www.swfcabin.com/open/1249505478 (use arrow keys to move)

But, as you can see; there is no collision detection. How can I make a collision detection as good as http://alternativaplatform.com/swf/d...t/flatfp10.swf ? Which technique can I use?

Thanks.

Well if you have the equations of the planes of the 3D world you generated, then you can simply shoot a ray into the world in the direction that you are moving. Then you can make the ray the length of how far you want to be from the wall before stopping your movement. You can then plug it into a ray to plane intersection formula and when a parameter s is less than 1 and greater than 0, then you have run into that wall.

For this method, google ray to plane intersection.

Or you can use a bounding box and see if the faces intersect with the box or not. A lot like finding if faces are in a viewing frustrum or not.
