I hope you will like it (and understand it, because im dutch and my english isnt perfect).

Too bad its still under construction, but it already covers the basics of the 3D space/grid, 3D movement, Collision Basics, Box Collision and Sphere/Distance Collision.

Here's a link:

The tutorial is full of examples and images when its finished.
Im too tired to work further (I was hoping to get it finished today, but everybody in my town is sleeping right now .. my eyes are hurting)

Normally I would offer hosting to you. Unfortunately I am not currently in a position to make that offer.

There is an optimization you could make to part of your code. The distance check you have as:



Could also be written as:



Which essentially removes the square root function altogether.

dude, great tutorial (i actually learned something from it! (which says a lot, since i already knew more than half of it.)(i'll have to remember that bit about ellipsoid collision))(i have a tendency to over-use parentheses) you're dutch?! understanding the tutorial wasn't a problem--your english is better than mine, and i've been speaking it my whole life! congrats, my friend

@nuclear glory Thanks anyway. Btw, thanks for your optimalization. I can use it with the normal distance check too (remove sqrt() and replace distance# with distance#*distance#)

@muscles (ik ben nederlands ja ) I'm dutch and believe me, my english is far from perfect
