This function is not supported in earlier versions.

Applies the reverse of the Transform object's transformation to the given 2D position.

This effectively converts the given position from the local coordinate space of the Transform into global coordinates.

One use of this method can be to convert a screen-space mouse position into global world coordinates, if the given Transform has transformations applied that are used for a camera system in-game.

Function

Synopsis

globalX, globalY = Transform:inverseTransformPoint( localX, localY )

Arguments

number localX
The x component of the position with the transform applied.
number localY
The y component of the position with the transform applied.

Returns

number globalX
The x component of the position in global coordinates.
number globalY
The y component of the position in global coordinates.
