[1.15.2] Override function for all entities


Recommended Posts

I've a custom version of the Entity.handleWaterMovement in a custom entity for testing, and is working on that entity. Now, I want that all entities in game(or maybe just LivingEntity) use this new function instead of the vanilla version. For my custom entities a very bad solution is to copy-paste that code, but for vanilla... 

Is there a way?


The code aim to enable water movement to a custom fluid checking for its tag. The rest of the functioon is unalterated for the moment.

public boolean handleWaterMovement() {
        ResourceLocation customFluidTag = new ResourceLocation(MyMod.MOD_ID, "cust_fluid");
        if (this.getRidingEntity() instanceof BoatEntity) {
            this.inWater = false;
        } else if (this.handleFluidAcceleration(FluidTags.WATER) || this.handleFluidAcceleration(FluidTags.getCollection().getOrCreate(customFluidTag))) {
            if (!this.inWater && !this.firstUpdate) {
            this.fallDistance = 0.0F;
            this.inWater = true;
        } else {
            this.inWater = false;
        return this.inWater;

I'm assuming that you don't want to add your custom fluid to the vanilla "water" Tag, then?

(i.e. like this https://github.com/TheGreyGhost/MinecraftByExample/tree/master/src/main/java/minecraftbyexample/mbe35_recipes)


If not - I don't think there is an easy way, no.


I don't have experience with this recently but the two key words that might be worth searching for are




They will let you overwrite parts of the vanilla Entity::handleWaterMovement code.  It's a bit arcane and can be rather brittle but might be your only choice.

    • I want to download Forge 1.20.6, but when I press download, it redirects me to Adfocus and does not provide any download. I have never encountered such a problem when I downloaded Forge 1.18.2 at least 12 months ago.
    • did you find any solutions? i have the same problem and also that mahito doesnt transform
    • Here's a simple example to solve this particular issue: public class ModArmorMaterials { public static final DeferredRegister<ArmorMaterial> ARMORS = DeferredRegister.create(Registries.ARMOR_MATERIAL, MyModName.MOD_ID); public static final RegistryObject<ArmorMaterial> COPPER = registerArmor("copper", Util.make(new EnumMap<>(ArmorItem.Type.class), enumMap -> { enumMap.put(ArmorItem.Type.BOOTS, 1); enumMap.put(ArmorItem.Type.LEGGINGS, 4); enumMap.put(ArmorItem.Type.CHESTPLATE, 5); enumMap.put(ArmorItem.Type.HELMET, 2); enumMap.put(ArmorItem.Type.BODY, 4); }), 12, SoundEvents.ARMOR_EQUIP_IRON, 0.0F, 0.0F, () -> Ingredient.of(Items.COPPER_INGOT)); private static RegistryObject<ArmorMaterial> registerArmor(String pGroup, EnumMap<ArmorItem.Type, Integer> pEnumMap, int pEnchantmentValue, Holder<SoundEvent> pEquipSound, float pToughness, float pKnockbackResistance, Supplier<Ingredient> pRepairIngredient) { List<ArmorMaterial.Layer> pLayerList = List.of(new ArmorMaterial.Layer(new ResourceLocation(pGroup))); return registerArmor(pGroup, pEnumMap, pEnchantmentValue, pEquipSound, pToughness, pKnockbackResistance, pRepairIngredient, pLayerList); } private static RegistryObject<ArmorMaterial> registerArmor( String pGroup, EnumMap<ArmorItem.Type, Integer> pEnumMap, int pEnchantmentValue, Holder<SoundEvent> pEquipSound, float pToughness, float pKnockbackResistance, Supplier<Ingredient> pRepairIngredient, List<ArmorMaterial.Layer> pLayerList) { return ARMORS.register(pGroup, () -> new ArmorMaterial(pEnumMap, pEnchantmentValue, pEquipSound, pRepairIngredient, pLayerList, pToughness, pKnockbackResistance)); } public static void register(IEventBus eventBus) { ARMORS.register(eventBus); } } Essentially, the TierSortingRegistry has been removed and so you now need to set up your own DeferredRegister. Please see the minecraftforge GitHub for more information; I found this solution through their issues (https://github.com/MinecraftForge/MinecraftForge/issues/9961)
    • How did I even leave that in there? I’ll try it in a bit, that very well could be it.
