Ok , I understand why... I'm using classes like the following to organize my entites, they are all inner classes of the EntityTypesInit public static final class AlbinoCow { public static final String registryName = "albino_cow"; public static final RegistryObject<EntityType<AlbinoCowEntity>> registryObject = EntityTypesInit.ENTITY_TYPES.register( registryName, () -> EntityType.Builder.create(AlbinoCowEntity::new, EntityClassification.CREATURE) .size(EntityType.COW.getWidth(), EntityType.COW.getHeight()) .build(new ResourceLocation(EarthtojavamobsMod.MOD_ID, registryName).toString()) ); public static final int eggPrimaryColor = 0xdecac3; public static final int eggSecondaryColor = 0xf0a590; public static final String[] spawnBiomes = BiomeSpawnHelper.getBiomesListFromBiomes(BiomeSpawnHelper.PLAINS, BiomeSpawnHelper.MOUNTAINS, BiomeSpawnHelper.GRAVELLY_MOUNTAINS); } They are called when register the spawn in biomes for each entity, but a projectile have no spawn and never been called, so it could be the problem. I think I've to find another way to organize them. Thank you so much.

ENTITY_TYPES is the register where I have all the entities. public class EntityTypesInit { public static final DeferredRegister<EntityType<?>> ENTITY_TYPES = new DeferredRegister<>(ForgeRegistries.ENTITIES, EarthtojavamobsMod.MOD_ID); ... public static final class MelonSeedProjectile { public static final String registryName = "melon_seed_projectile"; public static final RegistryObject<EntityType<MelonSeedProjectileEntity>> registryObject = ENTITY_TYPES.register( registryName, () -> EntityType.Builder.<MelonSeedProjectileEntity>create(MelonSeedProjectileEntity::new, EntityClassification.MISC) .size(0.25F, 0.25F) .build(new ResourceLocation(EarthtojavamobsMod.MOD_ID, registryName).toString()) ); } ... } Is called from the mod constructor @Mod(EarthtojavamobsMod.MOD_ID) public class EarthtojavamobsMod { public static final String MOD_ID = "earthtojavamobs"; public EarthtojavamobsMod() { final ModLoadingContext modLoadingContext = ModLoadingContext.get(); final IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus(); FluidInit.FLUIDS.register(modEventBus); BlockInit.BLOCKS.register(modEventBus); EntityTypesInit.ENTITY_TYPES.register(modEventBus); // <--- CALLED HERE ItemInit.ITEMS.register(modEventBus); RecipesInit.RECIPES.register(modEventBus); modEventBus.register(this); modEventBus.addListener(this::setup); modLoadingContext.registerConfig(ModConfig.Type.CLIENT, ConfigHolder.CLIENT_SPEC); modLoadingContext.registerConfig(ModConfig.Type.SERVER, ConfigHolder.SERVER_SPEC); modLoadingContext.registerConfig(ModConfig.Type.COMMON, ConfigHolder.COMMON_SPEC); } ... }

Any solution? I really can't see what I'm doing wrong.

Hi~ Here again with another stupid problem... This time I'm trying to register a new projectile following how the Snowball is make. I'm registering the entity like any other entity in the project but this one throw this error. Whats wrong this time?

Oh ok, thank you for the info.

I want to change texture of a mob (derived from IronGolemEntity) if it is attacking. I supposed that attackTarget contain the current target LivingEntity of my mob, so I was checking on the renderer if the entity.getAttackTarget() != null . The problem is the value is always null. I was supposing the NearestAttackableTargetGoal would fill the value in ... public void startExecuting() { this.goalOwner.setAttackTarget(this.nearestTarget); super.startExecuting(); } ... Is me wrong? There is another way?

More tests. Any entity inside the fluid SOURCE block have this bug. Removing the water tag don't trigger this issue, but entity act like if the block is air. Using a lead is possible to move out of the mud entities if far enough to force pull it. I don't really know where to look or what to do more...

After some test. The entity is unablento swim when is on the source block. Look like it can't find a path to wherever it want to go and start spinning. If the block is not a source, so is a flowing fluid, the entity is able to swim and go out of the fluid. It can be some bad configuration of the block? But the various parts look fine to me.

Update. The pigs spin also when they are not tempted. When tempted they spin if the player is far more than ~3 blocks else they just look. The spin issue is found only when they are in the Mud fluid. The mud is a normal fluid with some settings about tick rate and density and is tagged as minecraft:water and earthtojavamobs:mud, the MudFlowingFluidBlock extends a FlowingFluidBlock with the only change on lava interaction. Here the fluid code: FluidInit.java EDIT: Look like they are unable to swim in the custom fluid...

Anyone, any idea?

Changing priority do nothing. I've already did tests on priority. Also, the GoToMudGoal not execute while inside mud. public boolean shouldExecute() { return !this.muddy_pig.isInMud() && super.shouldExecute(); } And yes, the isInMud flag work properly or the texture would not change accordingly.

My little muddy pig love mud so much he don't care if I show him a juicy carrot. So, instead of going out of the mud and follow me, he spin on the spot. I've spent last hour reading all the various goal, trying to find some incompatibility, or some pathfinding issue. I've seen there was a similar bug in 1.14.x and 1.15.1, can it be related? Or I simply messed up the entity goals? The code of the entity is long, here the link to the github repo: https://github.com/Slexom/earth2java/blob/1.2.2/src/main/java/net/slexom/earthtojavamobs/entity/MuddyPigEntity.java

Before making changes on how register things on the mod I was using the constructor without the supplier. Now I'm using the supplier and inside the constructor code there is this.fluid = null; . That's what generate the error. Close or delete this if you want.

Can't understand why I get a NullPointerException. The line 59 mentioned in the crash report is the first if statement. I've used .getOrCreate() just to avoid the null value .get() could return. This isn't the only check of this type around the mod and the others work fine. Code CrashReport

A little bit exaggerated for half line of code. I'll put my fluid back on the water tag and fix what broke(fog color, lava interaction, etc.). Thank you for your reply.
