Keeping track of Direction (after Rotation)

I'm fairly new to 3d (infact you might have seen my noob questions before) and I'm having trouble with keeping track of an entities direction/visible face.

Picture this. An object is flying through space, it rotates:
90 degrees along it's X axis
90 degrees along it's Z axis
90 degrees along it's Y axis
and finally...
-90 degrees along it's Z axis

Now the object is actually back facing where it started, however, the counters I've used to track rotations are not (X = 90, Y = 90, Z = 0). My dilema is knowing which way my ship is facing in space.

Does Blitz have an obvious feature for this that I'm unaware of?

I hope you understand what I'm talking about!

It's best not to try and track entity positions/rotations with variables like you might do in 2D -- just rotate it however much you need, then call EntityPitch/Yaw/Roll () to get its current rotation... same for X/Y/Z. You could of course read EntityX/Pitch/Whatever into a variable if you need to do some calculations on it afterwards.

Thanks! One of those 3d things eh?
