Pair: setCursorPosition

This function gets the current position of the mouse cursor. Note that for performance reasons, the world position returned is always 300 units away. If you want the exact world point (similar to onClientClick), use processLineOfSight between the camera position and the world x/y/z result of this function. (See example below)

Syntax

float|false, float, float, float, float getCursorPosition ( )

Returns

  • float|false: cursorX
  • float: cursorY
  • float: worldX
  • float: worldY
  • float: worldZ

Returns 5 values: cursorX, cursorY, worldX, worldY, worldZ. The first two values are the 2D relative screen coordinates of the cursor. The last 3 values are the 3D world map coordinates that the cursor points at. If the cursor isn't showing, returns false as the first value.

Code Examples

This example prints your cursors current world coordinates and relative screen coordinates to chatbox after using /cursorpos command.

function cursorInfo()
    -- is the cursor showing?
    if isCursorShowing() then
        -- get the cursor postion
        local screenx, screeny, worldx, worldy, worldz = getCursorPosition()


        -- make the accuracy of floats 4 decimals and print to chatbox
        outputChatBox( string.format( "Cursor screen position (relative): X=%.4f Y=%.4f", screenx, screeny ) )
        outputChatBox( string.format( "Cursor world position: X=%.4f Y=%.4f Z=%.4f", worldx, worldy, worldz ) )
    else
        outputChatBox( "Your cursor is not showing." )
    end
end
addCommandHandler( "cursorpos", cursorInfo )

This (untested) example uses processLineOfSight to calculate the exact world location: Warning, this script causes high CPU usage!

addEventHandler( "onClientRender", root,
    function()
        -- is cursor showing?
        if isCursorShowing() then
            -- get cursor position
            local screenx, screeny, worldx, worldy, worldz = getCursorPosition()


            -- get our camera matrix/position
            local px, py, pz = getCameraMatrix()


            -- calculate the exact distance between cursor and camera
            local hit, x, y, z, elementHit = processLineOfSight ( px, py, pz, worldx, worldy, worldz )


            -- draw the distance on screen
            dxDrawText( "Cursor at X:" .. x .. " Y:" .. y .. " Z:" ..  z, 200, 200 )


            -- if we got a collision detected and a valid element, draw it as well
            if hit and elementHit then
                dxDrawText( "Hit element " .. getElementType(elementHit), 200, 220 )
            end
        end
    end
)
