Damage Modification

Hello,
I am writing a simple damage modification plugin, and I have 2 questions. How do I determine the item in hand of a non-player living entity (i.e. a zombie)? Additionally, how do I modify the health of every livingentity in a world?

 

@Jakesully123456 Living entites have this method:
https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/LivingEntity.html#getEquipment()
This will return an EntityEquipment:
https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/EntityEquipment.html

From there you can call getItemInHand(), just like with players.

 

@I Al Istannen
Thanks, now my second question, how do I change the default health value for a certain type of mob?
For example, I want all creepers to have 80HP.

 

@Jakesully123456
https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Damageable.html#setMaxHealth(double)
The setMaxHealth(double amount) should work. However, you may need to heal the entity, because there their current health may stay the same.

 

@I Al Istannen
No, that just sets the max health, not their actual health
@Jakesully123456
Cast the entity to a Damageable and set their Health using .setHealth() and their max health using .setMaxHealth();.

 

@Zombie_Striker @I Al Istannen
That is not the issue. I know how to set the health, I need a method to ensure that all mobs are given the appropriate health value. Can I set it on mob spawn, should I schedule. Repeating event to constantly set all entities per world to have more health? I need a method to ensure all mobs are at the modified health value.

 

@Jakesully123456 I know that there is an event for mob spawns, so just use that event, and then used the methods mentioned above to set their health the way you want to.

 

@Jakesully123456

Code:

public void onEnable(){
for(World wo: getServer().getWorlds()){
for(Entity e : wo.getEntities()){
// set health
}
}
}

 

@Zombie_Striker You do know, that most certainly (except reloads) no chunks will be loaded at the onEnable()? Afaik this won't do anything then.

@Jakesully123456
You would have to either check with the spawn event or the ChunkLoad event. But again, at the moment the ChunkLoad event is called, no entites are in the chunk. I had that iussue before. You would need to wait a tick before scanning the chunk from the chunkLoadEvent.

ChunkLoadEvent: https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/world/ChunkLoadEvent.html
CreatureSpawnEvent: https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/entity/CreatureSpawnEvent.html
And you need to set the max health before, read this: https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Damageable.html#setHealth(double)
and after that set the health.

 

Any other ways to do it?

 

Delete the world, put your plugin and create a new one .

 

@MaTaMoR_ that, for many reasons is not possible. I'll manage it through chunk load events.
