Ok, I wrote this simple program to see if I could even detect collision using sparky's collision. I need some help.

+ Code Snippet

#include "DarkGDK.h"
#include "SC_Collision.h"

void DarkGDK ( void )
{
	dbSetDisplayMode( 800,600,32 );

	dbMakeObjectCylinder( 1,10 );
	dbColorObject( 1,dbRGB(200,0,0) );

	SC_Start( );

	dbMakeObjectBox (2, 10, 10, 10);
	dbPositionObject (2, 0, 0, 50);
	SC_SetupObject (2, 0, 0);


	//dbAutoCamOff( );
	//dbPositionCamera( 0,0,-30 );

	

	//setup the object for collision
	SC_SetupObject( 1,0,0 );


	int collide = 0;

	while ( LoopGDK( ) )
	{

		if (dbUpKey() == 1)
		{
			dbPositionObject (1, dbObjectPositionX(1), dbObjectPositionY(1), dbObjectPositionZ(1) + 1);
		}

		collide = SC_ObjectCollision (1, 2);

		if (collide > 0)
		{
			dbText ( dbScreenWidth()/2, dbScreenHeight()/2, "COLLISION!!!");
		}


		dbSync( );
	}
}

Even though the two objects collide it doesn't say "collision!".

Any help is appreciated.

I dont think your updating your objects.
SC_Update(1);
SC_Update(2);
Sprakys needs to know if the objects have moved.

SC_DrawObjectBounds(int obj);
Is a handy function when things are not going right with collision.
