You haven't actually *checked* for collision. You need to check by using SC_ObjectCollision() or using RayCasting. Personally, I would add gravity and make the player "fall" until the player's object and the world object collide and then stop decreasing the Y value of the player. Unfortunately this would have problems with walls. For that, use SC_SphereSlide() from the player's old position to his new one and then use the SC_GetStaticCollision functions to slide the player along the wall.

Hope it helps!

Like this:



I've noticed at the end of the main loop you are updating object 3 twice per frame - there is no need, update object 10 (the player) but not the level because the level isn't moving (it doesn't need to be updated if it doesnt move)

Note: there is a much better way of doing it with ray casts but you have to rewrite a lot of your code to implement that and I don't know how it works.

Wait, you compile the *exact* code included with the library, and it doesn't work? Or are you copying and pasting the code into your current project?

I have the same problem as you with animations, when I updated my files from the site, then no animations played. I had to copy my files from my computer over, and then it worked. If it's allowed, then I could send you my DarkGDK folder because I don't know why the update breaks animations!

Furthermore, try instead setting your objects up like this:



Instead of box collision, that is polygonal collision. Change "OBJECTID" to the ID of your player and level.
