Erratic Mob Chasing/Attacking Behavior

I’ve encountered a serious problem with my custom mob’s movement as it attempts to chase and attack its target:

• The model spins and jolts around during movement, making it struggle to catch up to a fleeing target
• The mob sometimes seems unable to deal damage to its target, even if it is right on top of it - it may or may not succeed in dealing damage after a delay

• Here is a clip demonstrating the problem: https://youtu.be/lHNZEsFEn9U?si=M4RWVaH-06JKx1kH

  I suspect that this may have something to do with the mob’s hitbox, as that has been giving me a bit of grief as well due to MCreator only allowing cuboid hitboxes (separate thread asking about that here: https://mcreator.net/forum/107909/custom-entity-hitboxes-length-and-width)

  If anyone has any ideas regarding how to fix this, I would be very grateful to hear them. Manually editing the code is an option as I am working with friends familiar with Java, I would just need to know what files to edit and where to find them.
