that little snippit was suggested by spoike. i threw it in for completeness.

The pich angle (_x) is inverted in the .v_angle field, which is why it must be multiplied by -1 when using .angles instead of .v_angle and vice versa. At least, that's what happens with the view angles in the engine code.

All QC fields are always present in all entities, so .v_angle is also present in all entities. But the engine only sets its value on client entities, because client entities are the only ones that have a viewport. On all other entities, its value is initialized as '0 0 0' and the engine never changes it by itself, so you could use it for other things.

Oh, I guess I know the problem. You're not using that code on the monsters, you're only using it on the player(s). The thing is, the player can still look around while he's dead, which means that his .v_angle can change after he's been killed.

The tpnl in your code seems to be a typo.

Now I'm sure of what's going on.

The problem is that the X, Y and Z angles in the QC code are a single transformation. To do it correctly, the model's vertices would have to be transformed twice: First by translating them around the rotation's angles, and then by translating their positions from a plane to another.

However, Quake doesn't support that. So, when you align the model to the plane, you lose its actual orientation's angles.

Maybe a way to hack around this is to use two entities for the corpses.
Don't set any model on the first entity, and set the model on the second entity instead.
Also, set the second entity to MOVETYPE_FOLLOW, and set the first entity as its owner.
Now you should be able to do the plane calculations on the second entity, the rotation calculations on the first entity, and the engine should do the transformations correctly... depending on how the MOVETYPE_FOLLOW extension was implemented.
