Retrieve the rotation of elements. Only clientside before 1.0.4

Syntax

float float float getElementRotation ( element theElement [, string rotOrder = "default" ] )

Required Arguments

  • theElement: The element whose rotation will be retrieved

Optional Arguments

  • rotOrder: A string representing the rotation order desired when returning the euler angles. If omitted, default value is "default". Allowed values are:
    • "default": default MTA behavior prior to 1.1, where rotation order depends on element type
    • "ZXY": rotation about the Z axis (up), then about the resulting X axis (right) and finally about the resulting Y axis (front). This is the default rotation order for objects
    • "ZYX": rotation about the Z axis (up), then about the resulting Y axis (front), and finally about the resulting X axis (right). This is the default rotation order for vehicles

The default rotation order for peds/players is Z-Y-X (clientside) and -Z-Y-X (serverside) but those rotation orders (set using "default" on peds) can not be used manually on other element types since they only exist due to historical and backward compatibility reasons. Specifying a rotation order other than "default" allows the same angles to later be uniformly used on several elements without having to consider their type.

Returns

  • rx, ry, rz: 3 floats representing the Euler rotation angles on the axis X, Y and Z (with the rotation order depending on the rotOrder argument) if element exists and is a valid element, false if it's invalid.

Example

If a player points at a player element with a gun, its rotation will appear in the chat box.
