I need help making a MonsterEntity hold an item (netherite_axe)

Thank you!

You should be able to use MobEntity#setItemStackToSlot

Oh, cool thanks. I'll try it out!

Doesn't work for some reason? I put it in my entity java class, and it's not rendering

 

help please

@Override
public void setItemStackToSlot(EquipmentSlotType slotIn, ItemStack stack) {
    this.setItemStackToSlot(EquipmentSlotType.MAINHAND, netherite_axe);
}

You are overriding the method, you need to call it.

You can do that in MobEntity#onInitialSpawn

Solved thanks
