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 also realized I never posted the full class so here it is. package com.github.erce312.informatikacraft.entities; import com.github.erce312.informatikacraft.init.InformatikacraftEntities; import com.github.erce312.informatikacraft.init.InformatikacraftItems;

I have tried to to that but had a lot of issues with aiArrowAttack and aiAttackOnCollide being set to private in the AbstractSkeletonEntity class. I've tried to rewrite them like this in my code private final RangedBowAttackGoal<AbstractSkeletonEntity> aiArrowAttack = new RangedBowAttackGoal<>(this, 1.0D, 20, 15.0F); private final MeleeAttackGoal aiAttackOnCollide = new MeleeAttackGoal(this, 1.2D, false) { public void resetTask() { super.resetTask(); Reaper.this.setAggroed(false); } public void startExecuting() { super.startExecuting(); Reaper.this.setAggroed(true); } }; and then override the setAttackGoal @Override public void setCombatTask() { if (this.world != null && !this.world.isRemote) { this.goalSelector.removeGoal(this.aiAttackOnCollide); this.goalSelector.removeGoal(this.aiArrowAttack); ItemStack itemstack = this.getHeldItem(ProjectileHelper.getHandWith(this, InformatikacraftItems.amethyst_bow)); if (itemstack.getItem() instanceof net.minecraft.item.BowItem) { int i = 20; if (this.world.getDifficulty() != Difficulty.HARD) { i = 40; } this.aiArrowAttack.setAttackCooldown(i); this.goalSelector.addGoal(4, this.aiArrowAttack); } else { this.goalSelector.addGoal(4, this.aiAttackOnCollide); } } } But the mob wouldn't spawn now.

So I have made a custom skeleton and a custom bow item, however when I give it to the custom skeleton he doesn't use it. Here is my 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.

https://github.com/erec312/informatikacraft

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.
