Well this program is trying to create a cube where the mouse is, but I want it to not create it if there is another cube right where that one is, and right now there is a few problems:
1) When a cube is created it is not created right where the mouse is
2) I don't know how to center the mouse in the middle of the screen
3) I was trying to use "<>" to say if it is not equal too, and that doesn't work

+ Code Snippet

dbSyncOn();
dbSyncRate(60);
int x = 1;

//Loop
    while( LoopGDK ( ) ) {
	int mousex = dbMouseX();
	int mousez = dbMouseZ();
	int mousey = dbMouseY();
	if (dbKeyState(57) == 1)
	{
		int objx = dbObjectPositionX(x);
		int objy = dbObjectPositionY(x);
		x++;
		if (objx <> newx) {
		if (objy <> newy) {
		dbMakeObjectCube(x,20);
		dbPositionObject(x,mousex,mousey,0);
		dbWait(50);
		int newx = dbObjectPositionX(x);
		int newy = dbObjectPositionY(x);
		}
		}
	}
	dbPositionCamera(0,mousex,mousey,mousez-100);
	dbText(0,0,dbStr(int(x)));


	dbSync();
    }
}

Always program as if the person maintaining your program is a psychopath that knows where you live

1) You have to position the cube with 3D world coordinates, but you are using dbMouseX() and dbMouseY(), which just return the 2D mouse coordinates on the screen.

2) You can try:

+ Code Snippet

dbPositionMouse( dbScreenWidth() / 2, dbScreenHeight() / 2 );

This will position the mouse cursor at the center of the screen.

3) The C++ expression for not equal is !=. Example:

+ Code Snippet

if ( a != b ) dbPrint( "a is not equal to b." );

Now the plot thickens, the fps decreases, and the awesomeness goes through the roof.

That's not going to work, you need to use the PickScreen commands in order to get the 3d coordinates of the mouse, the Mouse coordinates just give you the screen coordinates basically. you can use this function I use in pretty much every program, it's not perfect but it works.

+ Code Snippet

void mouseConvert()
{
	double pickVector =0;
	float xHit =0; 
	float zHit=0;
	float yHit=0;
	 dbPickScreen ( dbMouseX(), dbMouseY(),1200 ) ;
	 xHit = dbGetPickVectorX() + dbCameraPositionX(); //Pick the x and z location on 3d terrain of mouse location
	 zHit = dbGetPickVectorZ() + dbCameraPositionZ();//-dbCameraPositionY();
	  yHit = dbGetPickVectorY() + dbCameraPositionY();//-dbCameraPositionY();
	mm3dX=xHit;
	mm3dZ=zHit;
	mm3dY=yHit;
}

I tried this (Im leaving the no creating a cube where another one is out of it) but I get a undeclared variable error and the mouse does not stay at the center of the screen.
mm3dX=xHit;
mm3dZ=zHit;
mm3dY=yHit;.

+ Code Snippet

void DarkGDK ( void ) {


dbSyncOn();
dbSyncRate(60);
int x = 1;

//Loop
    while( LoopGDK ( ) ) {
	int mousex = dbMouseX();
	int mousez = dbMouseZ();
	int mousey = dbMouseY();
	if (dbKeyState(57) == 1)
	dbPositionMouse( dbScreenWidth() / 2, dbScreenHeight() / 2 );
	{
		dbMakeObjectCube(x,20);
		dbPositionObject(x,mousex,mousey,0);
		dbWait(100);
	}
	dbPositionCamera(0,mousex,mousey,mousez-100);
	dbText(0,0,dbStr(int(x)));


	dbSync();
    }
}

void mouseConvert()
{
	double pickVector =0;

Try this, there are some modifications you have to make in order to get it to work, and you wanna position the cube at mm3dx not mousex

Sorry its not working as easy as I think it should. For one, put the function at the top of the program and it should work

Hey,

As far as I know, you need to get the 3d vectors of your mouse position, and then create a cube there, you could check if there would be collision there where the last cube is placed, then it wouldnt create there the cube. But it would in another place where collision is 0.

Greets,
