So I have a world that consists of a floor plane and a bunch of smaller planes that lie perpendicular to it, I need to determine if the user has touched the screen space of the floor or of a building and if a building which building(buildings are smaller perpendicular planes)…
the screen coordinates are mapped out x increasing from 0 to + left to right and y 0 to + top to bottom
How would I go about implementing this in java?
Thanks,
