It wont because the world is one big .X file, with the ball within it, hence no collision...

Good news everyone! I really am THAT good...

http://www.nuclearglory.com have a very nice Dll that deals with this and adds sliding collision. It works with DB 1.13, DBP 3.1 and DBP 4

Hmmm.... so any suggestion if I wanna develop an indoor FPS like Quake without using BSP (as I heard BSP was very buggy). Do I create all the objects in the world like walls, crates, rocks, trees, etc., each of them in an individual .X file, and then position each of them manually using POSITION OBJECT? Wouldn't it be very messy when I need to position each these objects manually everytime the world is loaded?

How about collision detection against the world? Do I perform collision detection with EVERY objects in the world everytime the player makes a move? Wouldn't it be very inefficient?

Any good suggestion on this?? Thanks!

Well, from my test of having an object inside a city (one big .X file), I found that having one big .X file doesn't work (collision wise) - each part that you want detectable has to be a seperate .X object, and positioned seperately.

Usually I would suggest using separate parts and detcting collisions with all of them, but the Dll I mentioned allows you to build a whole level from and *.x and just detct collision with that.

Toady - It basically just detects collision with the object as a whole, but it can return the position and angle of the collision

So, unfortunately for cities etc, it will have to be split into several .X files....

Not necessarily - you could build a whole city and just slide collision of it, then place invisible boxes around each building or whatever to tell if a person is at that building - it would obviously dependwhat kind of game you were making

Kangaroo2, the DLL that you mentioned looks cool. But I couldn't find it. Can you give me a direct link to it? Thanks a lot!

Kangaroo2: Cheers mate but it was a joint effort With Matthew DeWalt, Administrator of the NuclearGlory Facility (mucho kudos). Kudos also to the many fine members of this board and the RGT who helped, particularly with the C++ code, and not least MrTAToad himself

I'm planning an updated release of the library in due course but not until my game gets finished (it's been like over a year in the making!)
