Hi all,

I'm pretty new to Dark GDK and am finding it's pretty nice...

...however, I'm having a problem with dbPickScreen() and can't seem to find a solution.

In the main loop, I have the following:



Basically, I'm using an isometric camera (overhead) and trying to determine where in the 3D World my mouse cursor is at so I can "drag" an object around the world on the X, Z axes.

It seems that dbPickScreen() isn't giving me any vector coords relative to the camera...all I get is 0, 0, 0.

Thanks for the help in advance!

As it turns out the problem was with dbSetCameraRange()

Apparently there is an issue with dbPickScreen() when you use dbSetCameraRange().

Only if the near range is 0 and/or the far range is incredibly high.

After dealing with this one I posted a page at the Wiki since there wasn't one available for dbPickScreen().
