love.graphics.transformPoint
Converts the given 2D position from global coordinates into screen-space.

This effectively applies the current graphics transformations to the given position. A similar Transform:transformPoint method exists for Transform objects.
screenX, screenY = love.graphics.transformPoint( globalX, globalY )
globalX number The x component of the position in global coordinates.
globalY number The y component of the position in global coordinates.
screenX number The x component of the position with graphics transformations applied.
screenY number The y component of the position with graphics transformations applied.
