This function gets the screen position of a point in the world. This is useful for attaching 2D gui elements to parts of the world (e.g. players) or detecting if a point is on the screen (though it does not check if it is actually visible, you should use processLineOfSight for that).

Syntax 

​float, ​float, ​float getScreenFromWorldPosition ( ​float x, ​float y, ​float z, [ ​float edgeTolerance = 0.0, ​bool relative = true ] )
Required arguments
  • x: A float value indicating the x position in the world.
  • y: A float value indicating the y position in the world.
  • z: A float value indicating the z position in the world.
Optional arguments

Note: when using optional arguments, you might need to supply all arguments before the one you wish to use.

  • edgeTolerance (default: 0.0): A float value indicating the distance the position can be off screen before the function returns false. Note: it's clamped down on both axies to the size of screen at the given axis*10
  • relative (default: true): A boolean value that indicates if edgeTolerance is in pixels [false], or relative to the screen size [true].

Returns

Returns two x , y floats indicating the screen position and float distance between screen and given position if successful, false otherwise.

  • float: x
  • float: y
  • float: z

Code Examples

This example add a '3d' text at coordinates 0, 0, 0 (center of map).

addEventHandler ( "onClientRender", root,
function ( )
  if ( getDistanceBetweenPoints3D ( 0, 0, 3, getElementPosition ( localPlayer ) ) ) < 50 then
    local coords = { getScreenFromWorldPosition ( 0, 0, 3 ) }
    if coords[1] and coords[2] then
      dxDrawText ( "Hello !", coords[1], coords[2], coords[1], coords[2], tocolor(255,255,255), 1, "default-bold" )
    end
  end
end )
