Oh yeah, that's work! I have missed "minecraft::" on the documentation. and for the modid, it's a private mod for my server so the conflicts are minimal but that's a good tip, Thanks !

Ok, so i found the solution after some test, i leave the code here if someone wants him if(itemStack.getItem().equals(ModItems.WULFENITE_HELMET) && !player.inventory.armorInventory.get(1).isEmpty() && !player.inventory.armorInventory.get(2).isEmpty() && !player.inventory.armorInventory.get(0).isEmpty()) // CHECK IF FULL ARMOR PUT ON THE PLAYER { if(player.inventory.armorInventory.get(1).getItem().equals(ModItems.WULFENITE_LEGGINGS) && player.inventory.armorInventory.get(2).getItem().equals(ModItems.WULFENITE_CHESTPLATE) && player.inventory.armorInventory.get(0).getItem().equals(ModItems.WULFENITE_BOOTS)) // CHECK IF BOOTS LEGGINGS AND CHESTPLATE IS YOURS { player.addPotionEffect(new PotionEffect(MobEffects.FIRE_RESISTANCE, 20, 0)); } }

Ok so i change : entitylivingbase.addPotionEffect(new PotionEffect(Potion.getPotionById(16), 20, 0)); with this entitylivingbase.addPotionEffect(new PotionEffect(MobEffects.NIGHT_VISION, 5, 1)); there is no error in my code but when i put my "Wulfenite Helmet" I have no effects given to me I think the helmet check on the "EntityEquipmentSlot.HEAD" doesn't work public void onArmorTick(World world, EntityLivingBase entitylivingbase, ItemStack itemStack) { ItemStack helmet = entitylivingbase.getItemStackFromSlot(EntityEquipmentSlot.HEAD); if(helmet.getItem() == ModItems.WULFENITE_HELMET) { entitylivingbase.addPotionEffect(new PotionEffect(MobEffects.NIGHT_VISION, 5, 1)); } }

I do this but it doesn't work public void onArmorTick(World world, EntityLivingBase entitylivingbase, ItemStack itemStack) { ItemStack helmet = entitylivingbase.getItemStackFromSlot(EntityEquipmentSlot.HEAD); if(helmet.getItem() == ModItems.WULFENITE_HELMET) { entitylivingbase.addPotionEffect(new PotionEffect(Potion.getPotionById(16), 20, 0)); } } I tried to search on the internet, but i only found a little piece of code I didn't know how i can do this, i have no more idea

Hello! I tried to add an effect when i wear my armor so i try some line of codes: @Override public void onArmorTick(World world, EntityPlayer player, ItemStack item) { if(player.inventory.armorItemInSlot(0) != null && player.inventory.armorItemInSlot(1) != null && player.inventory.armorItemInSlot(2) != null && player.inventory.armorItemInSlot(3) != null) { if(player.inventory.armorItemInSlot(0).getItem() == ModItems.WULFENITE_BOOTS && player.inventory.armorItemInSlot(1).getItem() == ModItems.WULFENITE_LEGGINGS && player.inventory.armorItemInSlot(2).getItem() == ModItems.WULFENITE_CHESTPLATE && player.inventory.armorItemInSlot(3).getItem() == ModItems.WULFENITE_HELMET) { player.addPotionEffect(new PotionEffect(Potion.getPotionById(16), 20, 0)); } } } Or @Override public void onArmorTick(World world, EntityPlayer player, ItemStack itemStack) { if (player.inventory.armorItemInSlot(3) != null && player.inventory.armorItemInSlot(3).getItem() == ModItems.WULFENITE_HELMET && player.inventory.armorItemInSlot(2) != null && player.inventory.armorItemInSlot(2).getItem() == ModItems.WULFENITE_CHESTPLATE && player.inventory.armorItemInSlot(1) != null && player.inventory.armorItemInSlot(1).getItem() == ModItems.WULFENITE_LEGGINGS && player.inventory.armorItemInSlot(0) != null && player.inventory.armorItemInSlot(0).getItem() == ModItems.WULFENITE_BOOTS) { player.addPotionEffect(new PotionEffect(MobEffects.WATER_BREATHING, 40, 4, false, false)); } } They work perfectly in Solo, but when i join my SpongeForge server 1.12.2 with my mod, and i wear my armor i get disconnect with the message "Internal Server Error" In the console, there's this error: net.minecraft.util.ReportedException: Ticking player at net.minecraft.entity.player.EntityPlayerMP.func_71127_g(EntityPlayerMP.java:459) ~[oq.class:?] at net.minecraft.network.NetHandlerPlayServer.redirect$onPlayerTick$zjb000(NetHandlerPlayServer.java:2056) ~[pa.class:?] at net.minecraft.network.NetHandlerPlayServer.func_73660_a(NetHandlerPlayServer.java:173) ~[pa.class:?] at net.minecraftforge.fml.common.network.handshake.NetworkDispatcher$1.func_73660_a(NetworkDispatcher.java:209) ~[NetworkDispatcher$1.class:?] at net.minecraft.network.NetworkManager.func_74428_b(NetworkManager.java:285) ~[gw.class:?] at net.minecraft.network.NetworkSystem.func_151269_c(NetworkSystem.java:180) [oz.class:?] at net.minecraft.server.MinecraftServer.func_71190_q(MinecraftServer.java:790) [MinecraftServer.class:?] at net.minecraft.server.dedicated.DedicatedServer.func_71190_q(DedicatedServer.java:397) [nz.class:?] at net.minecraft.server.MinecraftServer.func_71217_p(MinecraftServer.java:668) [MinecraftServer.class:?] at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:526) [MinecraftServer.class:?] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_212] Caused by: java.lang.NoSuchMethodError: net.minecraft.entity.player.InventoryPlayer.func_70440_f(I)Lnet/minecraft/item/ItemStack; at fr.mrsawz.sawzmod.items.armor.ArmorBase.onArmorTick(ArmorBase.java:71) ~[ArmorBase.class:?] at net.minecraft.entity.player.InventoryPlayer.func_70429_k(InventoryPlayer.java:371) ~[aec.class:?] at net.minecraft.entity.player.EntityPlayer.func_70636_d(EntityPlayer.java:511) ~[aed.class:?] at net.minecraft.entity.EntityLivingBase.func_70071_h_(EntityLivingBase.java:2179) ~[vp.class:?] at net.minecraft.entity.player.EntityPlayer.func_70071_h_(EntityPlayer.java:234) ~[aed.class:?] at net.minecraft.entity.player.EntityPlayerMP.func_71127_g(EntityPlayerMP.java:382) ~[oq.class:?] ... 10 more [11:08:16]: [NetHandlerPlayServer] MrSawZ lost connection: Internal server error I don't know why and i didn't found any pieces of information on the internet.
