if anyone wants to know, i figured out finally how to use it. You have to covert the mouse coords back into the format like you get from WorldToScreen My messy functions below seem to work (x/y are the mouse pos) px = (((float)x)/(0.5f*ScreenWidth))-1; py = (-1.0)*((((float)y)/(0.5f*ScreenHeight))-1);

All i can find is a huge index which is a bit difficult to use when your looking for specific things. > > Thanks,Tom > -- > > > _______________________________________________ > To unsubscribe, edit your list preferences, or view the list archives, please visit: > http://list.valvesoftware.com/mailman/listinfo/hlcoders > _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
