/ the wizard has created a very simple 3D project that uses Dark GDK
// it can be used as a starting point in making your own 3D games

// whenever using Dark GDK you must ensure you include the header file
#include "DarkGDK.h"
#include "SC_Collision.h"

// the main entry point for the application is this function
void DarkGDK ( void )
{
	// in this application we are going to create some 3D objects
	// and position them on screen

	// when starting a Dark GDK program it is useful to set global
	// application properties, we begin by turning the sync rate on,
	// this means we control when the screen is updated, we also set
	// the maximum rate to 60 which means the maximum frame rate will
	// be set at 60 frames per second

	// This has to be ran before any of the psarky commands are used
	SC_Start();

	// some varibles I used for the program
	float fMouseX;
	float fMouseY;
	int iButtonID;
	int iSpriteCollision;

	// standard
	dbSyncOn   ( );
	dbSyncRate ( 60 );

	// set our random seed to a value from the timer, this will help
	// to ensure each time we run our program the random values appear
	// more random
	dbRandomize ( dbTimer ( ) );
