I'm trying to setup simple bounding box collisions with 4 directional movement. I have a sprite with a bounding box on it, the sprite moves around the screen in 4 directions. I want to setup a series of box's on the screen that the sprite bounding box can collide against. That part is easy enough, but I want the sprite to slide against the edge of the box its colliding with. So if the sprite collides with the box from the side I want the sprite to still be able to move vertically. Any one have any psuedo/code to share?
Thanks

First, if this is 2D then theres no boxes but squares.

So, really, doing a calculation in one more dimension that you need, is not very wise


The sliding is part of the collision response and not the detection. I recommend you to read about collision response and start your own sliding response, if you get stucked then post the problem and we'll join forces to help you solve it.

I believe its better if you understand the entire process before!.

If you find it too hard, I will post an example of custom 2D collision with sliding response, if it makes anyone happy that is. But you should try first.

When I said box I meant a 2D box/square (Not used to 3D terminology). Time for a google crawl for rigid body physics and that glorious stuff!

I think a box is not the same as a square... I know what you meant but It's just that it's wrong. For example when people saids "I need a couple of ..." Well a couple means 2 but they'll grab more than 2, They refer as a "bunch" but the world COUPLE means 2... Same thing in this case almost, box, square.. none are the same.

And yes, "google will provide"

Aha Success! Simple enough really no need for real physics in my situation at least. Thanks Captain "dagcrack" Pedantic anyway for the offer
