Well my game doesn't really crash, the entity just doesn't spawn and this is the output in the console. Sorry for using the wrong expression.

I have tried to to that but had a lot of issues with aiArrowAttack and aiAttackOnCollide being set to private in the AbstractSkeletonEntity class.

Yes the class extends the AbstractSkeletonEntity.public class Reaper extends AbstractSkeletonEntity { public Reaper(EntityType<? extends AbstractSkeletonEntity> type, World wotldIn) { super((EntityType<? extends SkeletonEntity>) InformatikacraftEntities.REAPER, wotldIn); } @Override protected void setEquipmentBasedOnDifficulty(DifficultyInstance difficulty) { super.setEquipmentBasedOnDifficulty(difficulty); this.setItemStackToSlot(EquipmentSlotType.MAINHAND, new ItemStack(InformatikacraftItems.amethyst_bow)); } @Override protected SoundEvent getStepSound() { return null; } }

I've made a custom skeleton entity and given him a custom bow but he doesn't shoot/use it. The skeleton just melee attacks me. I've tried to override the setCombatTask and attackEntityWithRangedAttack. @Override public void setCombatTask() { this.getHeldItem(ProjectileHelper.getHandWith(this, InformatikacraftItems.amethyst_bow)); super.setCombatTask(); } @Override public void attackEntityWithRangedAttack(LivingEntity target, float distanceFactor) { ItemStack itemstack = this.findAmmo(this.getHeldItem(ProjectileHelper.getHandWith(this, InformatikacraftItems.amethyst_bow))); super.attackEntityWithRangedAttack(target, distanceFactor); } InformatikacraftItems.amethyst_bow = new BowItem(new Item.Properties().defaultMaxDamage(1000).group(ItemGroup.TOOLS)).setRegistryName(location("amethyst_bow")), I've also checked if my custom bow is an instance of BowItem, which it is. try { BufferedWriter BR = new BufferedWriter(new FileWriter("C:\\Users\\erikp\\Documents\\test.txt")); if(InformatikacraftItems.amethyst_bow instanceof BowItem) BR.write("true"); else BR.write("false"); BR.flush(); BR.close(); }catch(Exception e) { }

Thank you all

https://github.com/erec312/informatikacraft. Ok I have changed it. Thank you for your patience.

I've tried to extend AbstarctSkeletonEntity insted of SkeletonEntity and also to give him a vanilla item. But in both cases the entity isn't holding the item.

Could you post your code ?

Yes the code is being called Reaper.setEquipmentBasedOnDifficulty(DifficultyInstance) line: 24 This is the stack from the debugger.

package com.github.erce312.informatikacraft.entities; import com.github.erce312.informatikacraft.init.InformatikacraftEntities; import com.github.erce312.informatikacraft.init.InformatikacraftItems; import net.minecraft.entity.EntityType; import net.minecraft.entity.monster.SkeletonEntity; import net.minecraft.inventory.EquipmentSlotType; import net.minecraft.item.ItemStack; import net.minecraft.world.DifficultyInstance; import net.minecraft.world.World; public class Reaper extends SkeletonEntity { @SuppressWarnings("unchecked") public Reaper(EntityType<? extends SkeletonEntity> type, World wotldIn) { super((EntityType<? extends SkeletonEntity>) InformatikacraftEntities.REAPER, wotldIn); } @Override protected void setEquipmentBasedOnDifficulty(DifficultyInstance difficulty) { super.setEquipmentBasedOnDifficulty(difficulty); this.setItemStackToSlot(EquipmentSlotType.MAINHAND, new ItemStack(InformatikacraftItems.amethyst_bow)); } }

The skeletons aren't holding the custom bow, nor using it when attacking.

I've tried to Override the setEquipmentBasedOnDifficult, but haven't got it to work this way. Thanks for the quick reply. @Override protected void setEquipmentBasedOnDifficulty(DifficultyInstance difficulty) { super.setEquipmentBasedOnDifficulty(difficulty); this.setItemStackToSlot(EquipmentSlotType.MAINHAND, new ItemStack(InformatikacraftItems.amethyst_bow));

I've been trying to make a custom mob that extends SkeletonEntity. However when I spawn him he isn't wearing a bow. I would like him to carry a custom bow which I have already created. I am new to the @Overrirde so I am asking for help.

Right, so I am a little late. I had the same issue. Just copy the vanilla bow .json file and replace the name of the bow and modid. Then you need to create separate item .json's for all the stages of a bow being pulled. It's important than in the parent line you set the item as bow. Then once you make the textures for all stages it should work. "parent": "item/bow" The vanilla bow .json { "parent": "item/generated", "textures": { "layer0": "item/bow" }, "display": { "thirdperson_righthand": { "rotation": [ -80, 260, -40 ], "translation": [ -1, -2, 2.5 ], "scale": [ 0.9, 0.9, 0.9 ] }, "thirdperson_lefthand": { "rotation": [ -80, -280, 40 ], "translation": [ -1, -2, 2.5 ], "scale": [ 0.9, 0.9, 0.9 ] }, "firstperson_righthand": { "rotation": [ 0, -90, 25 ], "translation": [ 1.13, 3.2, 1.13], "scale": [ 0.68, 0.68, 0.68 ] }, "firstperson_lefthand": { "rotation": [ 0, 90, -25 ], "translation": [ 1.13, 3.2, 1.13], "scale": [ 0.68, 0.68, 0.68 ] } }, "overrides": [ { "predicate": { "pulling": 1 }, "model": "item/bow_pulling_0" }, { "predicate": { "pulling": 1, "pull": 0.65 }, "model": "item/bow_pulling_1" }, { "predicate": { "pulling": 1, "pull": 0.9 }, "model": "item/bow_pulling_2" } ] }

I've been working on a new entity and the spawn egg shows up, however when I spawn it the texture is missing (black and purple). I can't figure out why. I've followed youtube tutorial. I would appreciate a little help.
