GetTileFracAtPosition() public method

Gets the tile coordinate at position. This can be used to obtain tile or color data explicitly from layers The fractional value returned is the fraction into the current tile Returns true if the position is within the tilemap bounds
public GetTileFracAtPosition ( Vector3 position, float &x, float &y ) : bool
