Unit Selection

Hi all,
Is there a command that tells where a 3D model is being displayed on the screen? I will use this for selecting and commanding units in an RTS game.

It is CameraProject. It converts a x/y/z coordinate to the x/y coordinates on screen.
Use: "cameraproject camera, x, y, z", then read projectedx(), projectedy()

camera = CreateCamera()
; This must be set for all entities you want to be pickable
EntityPickMode myentity, 2
.
.
.
; these are in your main loop
if MouseHit(1) = 1
  CameraPick(camera, MouseX(), MouseY())
  PickedEnt = PickedEntity()
  if PicketEnt = myentity
    ; do what ever you want to do
  end if
End IF
.
.
.


I hope this help...

Thanks guys; I'll try this out.

If PickEnt = myentity


Is "myentity" a entity that was loaded before the "camera = CreateCamera()"? If so can "myentity" be a entity (variable) in a type?


Moraldi(Posted 2006) [#6]
As far as I know yes it can be a field of a type

Okay. Thanks for your help Moraldi.
