Routine for any collisions

[gnasen]

Hi folks,

I read very often that something like a collision routine is missing, so I decided to write my own. I hope it is as easy to use as I tried to make it.
There are 3 testprograms (with source) and a documentation in the package.

Features:
-create any polygons as hitbox
-move and rotate hitboxes
-very fast check if hitboxes collide
-easy to use with pb like syntax
-linux and windows compatible, 64bit not checked yet
-create hitbox out of a sprite

Little, good readable example with awesome graphics:

I improved the speed of the collision checks and got a speedboost of 50% on different collisions and more then 600% if there is no collision between some triangles (which are part of every hitbox).

Have fun. Would be happy about some further testing. And maybe some Feedback

Danke

Very nice!

I just tested without trying to understand the code for now, don't have time ATM.

But thank you very much for sharing it, I certainly will look into it.

added a requested function to create a hitbox out of a sprite. So its very easy to create hitboxes.

col_import(sprite,transcolor,gridsize)

transcolor is the not solid area, gridsize the "scan resolution".

Have fun

Looks interesting! Will try it with my particle system.

It might be a bit of a long shot, but does anyone still have this? I don't think it's on RSBasic.de.

I do. I am not quite sure if I have the latest version though. The link in the first post was a zip and mine is a rar.

I looked over the code and updated it to PureBasic v5.72 so it is runnable and changed variables from .l to .i for example. I also increased the readability a little with some added returns and spaces. I finished it all up by zipping it and placing it on DropBox.

Here's the link. It will be available for a while though I may eventually remove the link to it.

I do.

Thank you!
