GetScreenFromWorldPosition
Jump to navigation
Jump to search
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 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. For more information on optional arguments, see optional arguments.
- edgeTolerance: 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: 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.

Client-side ScriptThis 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 )
