Probably not very helpful, I'm new to this, but couldn't you just set all y values to -y (because the y-axis is inverted in 2-d), and get rid of all z values?

Lookup the commands

object screen x
and
object screen y

they return the screen coords of an object on screen

What i'm trying to get the 2d coordinates from is a particles. Because i want to use it as an explosion effect in my 2d tank game.
I dont think i can use the OBJECT SCREEN X or OBJECT SCREEN Y with a particles

Yes, you will not be able to use the object screen x() and object screen y() commands since they do not reference particles.

Why not then make a dummy object that is invisible and just position it at the particles position. Then you can call the object screen x() and object screen y() of the dummy object.
