Heya,

So I'm creating a mob (Tuff Golem) that can stack on top of one another, and am using the mount/dismount mechanic as the way to do it.  Everything is working fine, except for the hitbox.  If the bottom entity moves under a block that the stacked entities will be inside of, they suffocate and die.

To combat this, I'm going to try to increase and decrease the hitbox of the bottom-most Tuff Golem accordingly depending on how many Tuff Golems are stacked on top of it.

I have these two methods to get the bottom-most Tuff Golem, and the number of Tuff Golems stacked on it:

// Recursively loop through whichever tuff Golem is selected, and return the lowest one.
public TuffGolemEntity getLowestTuffGolem(TuffGolemEntity tuffGolem) {
  if (!tuffGolem.isPassenger()) {
    return tuffGolem;
  } else {
    return (TuffGolemEntity) getLowestTuffGolem(tuffGolem).getVehicle();
  }
}

// Recursively loop through each Tuff Golem above the selected one until the top one is reached.
public int getNumOfTuffGolemsAbove(TuffGolemEntity tuffGolem, int i) {
  if (!tuffGolem.isVehicle()) {
    return i;
  } else {
    return getNumOfTuffGolemsAbove((TuffGolemEntity) Objects.requireNonNull(tuffGolem.getPassengers()), i + 1);
  }
}

I'm not quite sure if there's a method to get or change an Entity's hitbox, but if there is, I would appreciate a point in that direction.

Alternatively, if there's a better way to approach this, I'd also love to hear about it!

I appreciate any help!

Sorry for the late reply, it took me a bit to figure it out fully but I got it thanks to your reference.  Thanks again, warjort.
