Hello everybody! I'm totally new to Soya3d (and to 3d programming... it's always been good ole 2d graphics for me up till now), and I'm wondering about three things:
The (probobaly) easy one: For things like selection of multiple units, it'd be nice to draw a 2d rectangle on the screen. Is there a way to do this, short of some horrible abuses of the widget system? Something like "drawPixel(x, y, color)"? The probobaly harder one: For some purposes, it might be nice to highlight a portion of the ground (think about the "unit selection" rings on the ground around a selected unit or highlighting the area that will be occupied by a building on the ground). The only idea I have been able to come up with was a directional light source that would shine at the area, or something really really sick involving a slightly elevated copy of the terrain with a mostly transparent texture. Both ways feel like they are very definitely not what one should do. The third thing: I can get the mouse coords translated to 3d coords, but I have to supply a z coordinate. I haven't been able to find anything similiar where I can supply the y coordinate. Do I really have to get the 3d coords for 2 different z values, and calculate the 3d coords for a given y value from that? I'd be really thankful for any pointers concerning any of these three things. Thanks a lot in advance, -Wojtek
