There should be two (if not more) solutions to your problem.

1. You could use the commands mousey() and mousex(). Like this for example:


You need to make something happen when the mouse is clicked. I don't know what exactly you want, Is it - In 2D or 3D? What appears - an Object? a Sprite? an Image? a Bitmap?

2. You could make use somehow of the screen commands, such as the position of the mouse on the screen, or make an object be the mouse, or whatever. I really haven't used this command set much, I just know it exists and may be helpful.

I hope this helps

steve c,

In addition, look up topics on the internet about vector math.

Im quite new to 3d, but I have a simple idea that COULD work.
Just make a super long sulyner that points wherever your pointing. It could either be transparent (not sure if there is 'transparent' in 3d) or it could be hiding behind the mouse. if you click and the sylinder is touching the object you want something happens.
Again this is just an idea.

THAT is the problem. How can you determine where the cylinder is in 3D space?

The only thing I could ever do is calculating the distance with the mouse...
