Server and clientfloat getDistanceBetweenPoints2D ( float x1, float y1, float x2, float y2 )
Required Arguments
- x1: The X position of the first point
- y1: The Y position of the first point
- x2: The X position of the second point
- y2: The Y position of the second point
Returns
Returns a float containing the 2D distance between the two points. Returns false if invalid parameters are passed.
