Ok, How do I check if the mouse coordinates are within a certain one of the segments on the picture above?

If you want to find the angle from the mouse to the screen centre, it's:
ATan2((GraphicsHeight()/2)-MouseY(),(GraphicsWidth()/2)-MouseX())

Can someone give me a quick explanation of what values the Sin,Cos,Tan,ASin,ACos,ATan,ATan2 return.

sector=Floor(ATan2(MouseX()-GraphicsWidth()/2,GraphicsHeight()/2-MouseY())/45)

Sector is 1 through 8, as shown:

\ 3|2 /
4 \|/ 1
5 /|\ 8
/ 6|7 \

Kip I'll work on this tomorrow. Solving stuff like this interests me.

Right off hand, number each triangle 1 through 8.

Or just use my intriangle function in the code archives
