I am trying to make a mod that revamps pre-existing hostile mobs in minecraft. I want to make zombies spawn in hordes and change some of the base stats, however I can not find any tutorial that really covers this. I can program Java just fine but all the libraries and necessary files confuse me. I am using forge and intelliJ to make this mod. Any help would be appreciated.

This sounds like a datapack imo. To change the weights for zombies, you can apply a biome modifier. As for hanging the base stats, you can apply the values using the EntityJoinLevelEvent event.

If it is not too much of a bother, can you point me to some resources that better explain those two concepts, biome modifiers and EntityJoinLevelEvent. Thank you for the advice!

 

We have docs on biome modifiers; however, EntityJoinLevelEvent only has the javadocs on the class itself. The basic concept is that it allows you to set values on the entity before it spawns into the world.

@SubscribeEvent

public static void zombieHealth(EntityJoinLevelEvent event)
{
if(event.getEntity() instanceof Zombie zombie)
{
zombie.setHealth(50);
}
}

 

this is the code im trying to use to set the zombies health to 50 from 20. It does not work. I have another event, livinghurtevent, that tells me the mobs health everytime i hit it and it works. I just cant get the zombie health part to work. Also as a test i wanted to add a part in the current event that would send a chat message that a zombie spawned and with what health it had. How would i fix this?

ctrl+click on setHealth

this worked. thank you all for your help!
