You setup collision for object 1 BEFORE you made the object. Same goes for object 2.

Programming? Not my Forte. But THAT is!

i know i figured that part out but what would be the best way to have a player stop moving when colliding with something in the level?

Well you can look at the Sliding Collision Demo included in Sparky's Collision. I know a lot of people say this, but it's true. I've implemented that code in my own game, and it works beautifully. (Now I gotta get the AI working )

Study the code till you get the gist of it, then try your luck at implementing it.

Ive been using two functions to handle collision. one to load the object and the other from the sliding demo



The collision code has been made more user friendly(its still the sliding demo but i changed a few things here and there).Just pass int the object's ID that you want to collide with the level. Also my groups are the same as in the demo.

dont forget to declare: (if i let out any there still in the demo)



NOTE* i also removed the movement handling from the function and im not sure if you can just add it back in but its worth a shot

a common C++ mistake .
In you declaration you have

it should be


if you don't see the difference , it is that you declared the function with a lowercase 'c' and defined it with a capital one 'C' . so change either one of the c's and that should do it.

PS: in the void Collision, where it references dbObjectPositionX,Y,Z() you should pass in 'iID' instead of '1' . That way you wont run into problems later when you want to use it on another object

in your level setup , you have your map and player in the same group so when it checks for collision between the two, it doesn't happen. so change it to this

did you change the SC_SetupObject(2,0,2) -> SC_SetupObject(2,2,2);

also you may want to try SC_SetupComplexObject(2,2,2);

SC_SetupComplexObject(2,2,2); sort of works but now the player just slides off the level even if the collision function isnt being used and the X coordinate isnt being updated it stays the same the level is just a flat plane

try using a sphere instead of a cube(just a long shot), or it may be that your using a .3DS which i've never used. the code itself works fine for me.
