DamageType

Registering new DamageTypes

public class MyDamageTypes {
    public static final DeferredRegistry<DamageType> DAMAGE_TYPES = DeferredRegistry.create(Registries.DAMAGE_TYPES, "plugin_id");
    
    public static final Holder<DamageType> MY_TYPE = DAMAGE_TYPES.register("my_type", id -> DamageType.builder(id)
            .damageEffect(DamageEffect)
            .exhaustion(1)
            .damageScaling(DamageScaling)
            .deathMessageType(DeathMessageType)
            .build());
}

Next in you Bootstrap class apply the registry:

public class MyBootstrap implements PluginBootstrap {
    @Override
    public void bootstrap(BootstrapContext ctx) {
        MyDamageTypes.DAMAGE_TYPES.apply();
    }
}

Now when you want to use it in, for example LivingEntity#damage, use one of the following methods to get the DamageSource:

MyDamageTypes.MY_TYPE.withCause(Entity)
MyDamageTypes.MY_TYPE.withDirect(Entity)
MyDamageTypes.MY_TYPE.withLocation(Location)
