Here is some code to modify spawn properties of zombiefied piglin's to spawn with armor and effects, I want to add it to make them angry at the players off spawn. I currently have code for this, but it does not work. any alternatives?
PigZombie zombifiedpiglin = (PigZombie) event.getEntity();
zombifiedpiglin.getEquipment().setHelmet(new ItemStack(Material.DIAMOND_HELMET));
zombifiedpiglin.getEquipment().setChestplate(new ItemStack(Material.DIAMOND_CHESTPLATE));
zombifiedpiglin.getEquipment().setLeggings(new ItemStack(Material.DIAMOND_LEGGINGS));
zombifiedpiglin.getEquipment().setBoots(new ItemStack(Material.DIAMOND_BOOTS));
zombifiedpiglin.addPotionEffect(new PotionEffect(PotionEffectType.DAMAGE_RESISTANCE, 999999999, 2));
zombifiedpiglin.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 999999999, 5));
zombifiedpiglin.setAngry(true);
};```
