Hi, A picture of my quadgame is atached. I need a kind of hitdetection for knowing where the player want's to set the next stone. I copied for testing the code of Sven but it doesn't work in the right way... As shown in the PickDepth or PickSquare example I added some hitrecord names to each grey square on the picture. When you click on the window, the same code like in the examples is executed. Except of the ortho2D call after the pickMatrix... I do not exactly know, what I have to fill there.. I tried it in the following way: justifyCamera :: GamePackage -> IO () justifyCamera gp = do let C {cp = camPers, cla=camLook} = gpGetCam gp (a,r,n,f) = camPers (e,c,u) = camLook -- matrixMode $= Projection -- loadIdentity GLU.perspective a r n f -- matrixMode $= Modelview 0 -- loadIdentity GLU.lookAt e c u I just commented out the change of the matrixMode. But that isn't right.. I have hits anywhere in the space but not on the planes :( Any good ideas? Or is there a good tutorial except of the gluSpec? My problem is that I don't understand how it should work in all details. Best regards Patrick
