Seems to work with new AxisAlignedBB(0,0,0,0,0,0) will tell you if crashes again

So I just managed to set up the breakpoints. Seems like I've done something wrong before. But still The Entity is only set dead when I reload the world. All other conditions than entityplayer==null seem to be false all the time. I'll appreciate any help. (Code is in my older posts) Also the Entity starts after a short time at its startposition with its new movement speed.

My Problem is I don't find anything about where the BoundingBox of the MultiPart is located

Thanks but how it binds the MUltiParts to the ModelParts My Code (AI is only for testing I'm working on a better one): package com.cruelar.cruelars_triforcemod.entities.boss; import com.cruelar.cruelars_triforcemod.Cruelars_Triforcemod_Core;

Hi guys, I'm working on a Entity, Stone Talus from The Legend of Zelda: Breath of the Wild, which don't take any damage of getting hit except at an ore deposit located on his back. I thought about a second hitbox as a weak spot located at the deposit, but I've no Code yet for the weak spot, because I don't know how to start, but I'll look if I find a way to start, so maybe I can give the code soon.

Look at this: Which forge version do you use?

@Animefan8888 and @diesieben07 I'm feeling we're close to the solution but I need your help as I don't know enough about this stuff yet.

I found something that might give a hint to the core of the problem: I'm calling shoot in the constructor and in the readSpawnData() If I remove it in the constructor the Entity can't move. If I remove it in readSpawnData() the behavior doesn't change I noticed it by reading the output of shoot() when I Right click to shoot: A minor thing would be that I want to have a chain or at least a line between the entity and the item and don't know how to do that.

which forge version have you installed? What says the quote about the log and the Forge version? diesieben007 was faster ?

I made some changes to improve its behavior. But Still it dies after a certain amount of time that static. Also it then still respawns with the same motion speed as the moment it died.

So why it doesn't works? Also setting the motion to o doesn't works. Is this also a problem with sides.

As the title says I want to replace the Renderer for the Player to add CustomArmorModels if an Item implementing IBauble out of Baubles API is worn. This is not about how to code the Renderer. I only need to know what I need to replace the Vanilla Renderer. But help on coding the Renderer/LayerBaubles in a clean way is appreciated.

As far as I know the recommended version is the latest version already tested completely so should be always stable, while latest version is the latest version with the latest bugfixes but also with possible yet undetected bugs. Usually you should use the recommended version.

clawshot_head.setDead(); What does this do? It references a new Entity just created in this method, not yet spawned in the world, and sets it to be dead. What it should do is gets the entity from the nbt and set that entity to be dead. Ok, I should give more details about that: The Entity is spawned correctly. Check. It lives a certain time. Check. (Not exactly what I want it to do but I should already know how to fix that) Then it dies (NOT by Right clicking again). Check And Respawns at its original spawnPos and moves again. But you're right about the error in the code,will fix that.

I've wrote a method to find the Entity Code package com.cruelar.cruelars_triforcemod.items; import com.cruelar.cruelars_triforcemod.Cruelars_Triforcemod_Core; import com.cruelar.cruelars_triforcemod.entities.projectiles.Clawshot_Head; import com.cruelar.cruelars_triforcemod.inventory.cruelars_triforcemod; import net.minecraft.client.renderer.block.model.ModelResourceLocation; import net.minecraft.entity.Entity; import net.minecraft.entity.EntityLivingBase; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.IItemPropertyGetter; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.nbt.NBTTagCompound; import net.minecraft.util.ActionResult; import net.minecraft.util.EnumActionResult; import net.minecraft.util.EnumHand; import net.minecraft.util.ResourceLocation; import net.minecraft.world.World; import net.minecraftforge.client.model.ModelLoader; import net.minecraftforge.fml.relauncher.Side; import net.minecraftforge.fml.relauncher.SideOnly; import javax.annotation.Nullable; import java.util.List; import java.util.Objects; import java.util.UUID; public class Clawshot_TP extends Item { public Clawshot_TP(){ this.setCreativeTab(cruelars_triforcemod.CRUELARS_TRIFORCEMOD); this.setRegistryName("clawshot_tp"); this.setUnlocalizedName(Cruelars_Triforcemod_Core.MODID+".clawshot_tp"); this.addPropertyOverride(new ResourceLocation("cast"), new IItemPropertyGetter() { @SideOnly(Side.CLIENT) public float apply(ItemStack p_apply_1_, @Nullable World p_apply_2_, @Nullable EntityLivingBase p_apply_3_) { if (p_apply_3_ == null) { return 0.0F; } else { boolean lvt_4_1_ = p_apply_3_.getHeldItemMainhand() == p_apply_1_; boolean lvt_5_1_ = p_apply_3_.getHeldItemOffhand() == p_apply_1_; if (p_apply_3_.getHeldItemMainhand().getItem() instanceof Clawshot_TP) { lvt_5_1_ = false; } return (lvt_4_1_ || lvt_5_1_) && p_apply_3_ instanceof EntityPlayer && ((EntityPlayer)p_apply_3_).fishEntity != null ? 1.0F : 0.0F; } } }); } @Override public ActionResult<ItemStack> onItemRightClick(World world, EntityPlayer entityPlayer,EnumHand enumHand) { ItemStack itemStack = entityPlayer.getHeldItem(enumHand); Clawshot_Head clawshot_head = new Clawshot_Head(world, entityPlayer); if (!world.isRemote) { if (!this.getTagCompoundSafe(itemStack).hasKey("shot") || !this.getTagCompoundSafe(itemStack).getBoolean("shot") || this.getEntityByUUID(Objects.requireNonNull(this.getTagCompoundSafe(itemStack).getUniqueId("head")),world,itemStack).isDead) { world.spawnEntity(clawshot_head); this.getTagCompoundSafe(itemStack).setBoolean("shot",true); this.getTagCompoundSafe(itemStack).setUniqueId("head",clawshot_head.getUniqueID()); } else { clawshot_head.setDead(); this.getTagCompoundSafe(itemStack).setBoolean("shot",false); } } return new ActionResult(EnumActionResult.SUCCESS,itemStack); } @SideOnly(Side.CLIENT) public void initModel(){ ModelLoader.setCustomModelResourceLocation(this, 0, new ModelResourceLocation(Objects.requireNonNull(getRegistryName()), "inventory")); } private NBTTagCompound getTagCompoundSafe(ItemStack stack) { NBTTagCompound tagCompound = stack.getTagCompound(); if (tagCompound == null) { tagCompound = new NBTTagCompound(); stack.setTagCompound(tagCompound); } return tagCompound; } public Entity getEntityByUUID(UUID entityUUID, World worldIn, ItemStack itemStack){ int lenght =worldIn.getLoadedEntityList().size(); List<Entity> loadedEntityList= worldIn.getLoadedEntityList(); Entity foundEntity = null; for (int i = 0;i<lenght;i++){ if (loadedEntityList.get(i).getUniqueID()==entityUUID){ foundEntity = loadedEntityList.get(i); } } return foundEntity; } } Error: Still the Entity respawns after being setDead. What am I missing?

I feel pretty dumb to ask but how get I an Entity by its UUID as world only has the method getPlayerEntitiesByUUID()

I know that I also try that but for big Problems like that I often start with Vanilla code that works quite similar like in this case the FishingRod and FishHook similar to my Clawshot and its head to get the theory. BTW: How would I add a signature to my posts?
