Hi, topic sounds simpler than it is. When I click right and hold the mouse pressed a panel opens:  Now, depending on the mouse position, an area on this panel should be selected. Even if the mouse is not on the panel but in the top cone, the left cone, the bottom cone or the right cone. When I release the right mouse button the appropriate weapon should be selected. Does anybody know a nice algorithm to map the mouse position to a panel area? Thanks!

Alternatively, use two HNFs...

maybe, but dont hate me if its total bullshit just writting my thoughts, maybe you lay a invisible image over the whole screen and fill them with 4 diffent colors as cones. Then maybe its possible to detect over which of the colors the mouse is moving?! Similar to colormap for terrains...but different. Again, maybe its total crap what i say...

The way you propose needs memory for 4 more images instead of a 2 line vector calculation as proposed by bart. But thank you for thinking
