HU/getCursorPosition
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 worldX/Y/Z result of this function. (See example below)

Visszatérési érték
Returns 5 values: cursorX, cursorY, worldX, worldY, worldZ. The first two values are the 2D relative screen coordinates of the cursor: cursorX goes from 0 (left side of the screen) to 1 (right side), cursorY goes from 0 (top) to 1 (bottom). The 3 values that follow are the 3D world map coordinates that the cursor points at. If the cursor isn't showing, returns false as the first value.

Példa
This example prints your cursors current world coordinates and relative screen coordinates to chatbox after typing cursorpos.
function cursorInfo()
if isCursorShowing() then -- if the cursor is showing
local screenx, screeny, worldx, worldy, worldz = getCursorPosition()
outputChatBox( string.format( "Cursor screen position (relative): X=%.4f Y=%.4f", screenx, screeny ) ) -- make the accuracy of floats 4 decimals
outputChatBox( string.format( "Cursor world position: X=%.4f Y=%.4f Z=%.4f", worldx, worldy, worldz ) ) -- make the accuracy of floats 4 decimals accurate
else
outputChatBox( "Your cursor is not showing." )
end
end
addCommandHandler( "cursorpos", cursorInfo )
This (untested) example uses processLineOfSight to calculate the exact world location:
Warning, using the script down there will cause high CPU usage.

if hit then
