Can I detect when an EntityItem is stopped using motionX, Y, Z?

to answer your question -- yes you can.  simply test if motionX, motionY, AND motionZ are all == 0.  If 0, the entity is truly stopped.

 

The long answer...they are adjustment vectors from the current position.

 

So, if entity is at X = 1.42, and motion X = -0.12, then after the next update tick, the entities position would be X=1.30.  If motionX was +0.12, the entity would be instead at X=1.54.

 

testing for exact zero for 'stopped' can be misleading...some of those numbers can be very small but non-zero, and the entity would appear stopped for all intents and purposes.  It might be better to test for sqrt(mx*mx+my*my+mz*mz)<=0.002 to see if the entity is just moving really really slow, and might as well be stopped
