Any chance you could implement billboards that are non-players, that keep their location on the floor relative to the camera? I've been tinkering with it some, but can't figure it out.
Also: how might I go about normalizing depth? I usually use depth=room_height-y, but the object doesn't draw with the shader when using that depth sorting method.
God, it's been so long since I touched this but it should be possible. I'll have to look into the code again to tell you how to calculate the relative coordinates of a billboard object so that you can place it accurately.
As for depth, it should be relative to the calculated y coordinate of an object but I didn't implement it because I struggled with it myself. Should I figure it out, I could get back to you.
I have make a quick tutorial on how to make billboards using the code already included in the shader code examples. It's pretty easy, actually.

Normalizing depth might be a bit harder but what you could do is pass the calculated height from the draw event into a defined variable and then set that in the end step event. Tell me if that works.
