i would say repairRate but blockland appears to ignore that datablock parameter
It does seem to ignore it, but %player.setRepairRate works.
Also, do you want it to immediately start regenerating or start after you haven't been damaged for a set amount of time?
I've pretty much finished everything you requested. I just need to fix the UVs on the model, make the rotate animation, and do the leaf rustling sound. Since you can't crouch, I made it so that when you push the crouch button you turn into the color of your paint can, for better blending in(transparency from transparent paint colors isn't inherited). I also made it so that you snap to the brick grid when you push the sit button.
