I'm trying to create a wand that when right clicked will give a potion effect to the entity the player is looking at. But for some reason the effect is not applied Here's the code i'm using right now package com.mw.items; import com.mw.MW; import com.mw.core.MWTabs; import com.mw.utils.EnumWands; import com.mw.utils.Utils; import net.minecraft.entity.Entity; import net.minecraft.entity.EntityLiving; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.init.MobEffects; import net.minecraft.init.SoundEvents; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.potion.Potion; import net.minecraft.potion.PotionEffect; import net.minecraft.util.ActionResult; import net.minecraft.util.EnumHand; import net.minecraft.util.SoundCategory; import net.minecraft.world.World; public class ItemWand extends Item{ private EnumWands type; public ItemWand(EnumWands typeIn) { this.setCreativeTab(MWTabs.TOOLS); this.maxStackSize = 1; this.setMaxDamage(256); this.type = typeIn; } @Override public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn) { if(!worldIn.isRemote) { if(this.type == EnumWands.CORRUPTER || this.type == EnumWands.HEALER) { Entity pointed = Utils.getLookingEntity(); if(pointed != null && pointed instanceof EntityLiving) { Potion potion; int effect = MW.RANDOM.nextInt(5); if(this.type == EnumWands.CORRUPTER) { switch(effect) { case 0: default: potion = MobEffects.POISON; break; case 1: potion = MobEffects.BLINDNESS; break; case 2: potion = MobEffects.LEVITATION; break; case 3: potion = MobEffects.SLOWNESS; break; case 4: potion = MobEffects.WEAKNESS; break; } worldIn.playSound((EntityPlayer)null, playerIn.posX, playerIn.posY, playerIn.posZ, SoundEvents.ENTITY_ENDERMITE_AMBIENT, SoundCategory.NEUTRAL, 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F)); } else { switch(effect) { case 0: default: potion = MobEffects.REGENERATION; break; case 1: potion = MobEffects.RESISTANCE; break; case 2: potion = MobEffects.ABSORPTION; break; case 3: potion = MobEffects.INSTANT_HEALTH; break; case 4: potion = MobEffects.STRENGTH; break; } worldIn.playSound((EntityPlayer)null, playerIn.posX, playerIn.posY, playerIn.posZ, SoundEvents.ENTITY_PLAYER_LEVELUP, SoundCategory.NEUTRAL, 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F)); } ((EntityLiving)pointed).addPotionEffect(new PotionEffect(potion, 30 * 20)); ItemStack itemstack = playerIn.getHeldItem(handIn); if (!playerIn.capabilities.isCreativeMode) { itemstack.damageItem(1, playerIn); } Utils.setCooldown(playerIn, this, 3); } } } return super.onItemRightClick(worldIn, playerIn, handIn); } } I'm sure the code got called because the wand goes in cooldown and the sound is played, it's just the effect doesn't apply to the mob (and both effect and entity are corrects). How can i fix this?

I made a custom chest but the rendering is giving some gltiches. First of all the chest is not rendering though the tileentity is registered. This is the TileEntityCode package com.mw.entities.tileentity; import com.mw.blocks.BlockChestMW; import com.mw.utils.EnumDimensions; import net.minecraft.block.Block; import net.minecraft.block.BlockChest; import net.minecraft.tileentity.TileEntity; import net.minecraft.tileentity.TileEntityChest; import net.minecraft.util.EnumFacing; import net.minecraft.util.math.BlockPos; public class TileEntityChestCorrupted extends TileEntityChest{ /** * Get the name of this object.

Also i've noticed that if i place a vanilla chest near my chest the vanilla chest is also rendered as invisible. How can i fix this?

If you don't care about the generated one but only the placed one you can catch the onBlockPlaced event and set your block instead of vanilla one (like i do with my custom flower pot)

In my mod i have a block that is a custom fire, wich class is just this public class BlockFireMW extends BlockFire{ public BlockFireMW() { super(); } } Nothing special. But in game i got 2 main problems. The first is that i can't break it. If i click on it to "break" or ignite, it will break the block underneath instead of just ignite the fire (like vanilla fire does). The second one is that an entity walking on this fire will not burn or get damage. So how can i fix those since in the main class i didn't found anything related to this?

I solved this looking at the EntityEnderPearl class and basically adding this functon to my entity class public void onUpdate() { EntityLivingBase entitylivingbase = this.getThrower(); if (entitylivingbase != null && entitylivingbase instanceof EntityPlayer && !entitylivingbase.isEntityAlive()) { this.setDead(); } else { super.onUpdate(); } } Hope that works too for you

*facepalm* Forgot to add that method to the entity class. I don't know how but in 1.10 that works too without the onUpdate method BTW is fixed now, thank you for your help

How can i check that?

Yes the Entity is registered and it does stay alive becaus on impact it cause an explosion. Is created server side like Ender Pearls public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn) { ItemStack itemstack = playerIn.getHeldItem(handIn); if (!playerIn.capabilities.isCreativeMode) { itemstack.shrink(1); } worldIn.playSound((EntityPlayer)null, playerIn.posX, playerIn.posY, playerIn.posZ, SoundEvents.ENTITY_PLAYER_HURT_ON_FIRE, SoundCategory.NEUTRAL, 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F)); Utils.setCooldown(playerIn, this, 2); if (!worldIn.isRemote) { EntityGranade entitygranade = new EntityGranade(worldIn, playerIn); entitygranade.setHeadingFromThrower(playerIn, playerIn.rotationPitch, playerIn.rotationYaw, 0.0F, 1.5F, 1.0F); worldIn.spawnEntity(entitygranade); } playerIn.addStat(StatList.getObjectUseStats(this)); return new ActionResult<ItemStack>(EnumActionResult.SUCCESS, itemstack); } The RenderSnowball class i noticed that sometimes is called (using a breakpoint in that class) and sometimes is not, but i don't understand why this happen

As by title, i have an entity that acts like a snowball (so it's throwable) but is not rendering when fired. This is how i register the rendering in my client proxy RenderingRegistry.registerEntityRenderingHandler(EntityGranade.class, new EntityGranadeFactory()); //The Entity Class public class EntityGranade extends EntityThrowable { private EntityLivingBase thrower; public EntityGranade(World worldIn) { super(worldIn); } public EntityGranade(World worldIn, EntityLivingBase throwerIn) { super(worldIn, throwerIn); this.thrower = throwerIn; } @SideOnly(Side.CLIENT) public EntityGranade(World worldIn, double x, double y, double z) { super(worldIn, x, y, z); } protected void onImpact(RayTraceResult result) { if(this.getThrower() != null && this.getThrower() instanceof EntityPlayerMP) { EntityPlayerMP player = (EntityPlayerMP)this.getThrower(); if(player.connection.getNetworkManager().isChannelOpen() && player.world == this.world) { EntityTNTPrimed tnt = new EntityTNTPrimed(player.world); tnt.world.createExplosion(tnt, this.posX, this.posY, this.posZ, 2.0F, true); } } this.setDead(); } } //The Factory Class public class EntityGranadeFactory implements IRenderFactory<EntityGranade>{ @Override public Render<? super EntityGranade> createRenderFor(RenderManager manager) { return new RenderSnowball<EntityGranade>(manager, MWItems.GRANADE, Minecraft.getMinecraft().getRenderItem()); } } I have other things registerd like this (like custom TNT) and they all works as well, is just this that is not rendering. So why this happen and how can be fixed?

I created a custom biome extended from the HIlls Biome. When i register this biome i don't add it to the villages biomes, but for some reason villages still spawns in my biome. How can i avoid this? This is the code for the biome package com.mw.world.biome; import java.util.Iterator; import java.util.Random; import com.mw.MW; import com.mw.core.MWBlocks; import com.mw.world.gen.feature.WorldGenVolcano; import net.minecraft.entity.monster.EntityMagmaCube; import net.minecraft.entity.monster.EntityPolarBear; import net.minecraft.entity.monster.EntitySkeleton; import net.minecraft.entity.monster.EntityStray; import net.minecraft.init.Biomes; import net.minecraft.init.Blocks; import net.minecraft.util.math.BlockPos; import net.minecraft.world.World; import net.minecraft.world.biome.Biome; import net.minecraft.world.biome.BiomeHills; import net.minecraft.world.chunk.ChunkPrimer; import net.minecraft.world.gen.feature.WorldGenIceSpike; import net.minecraft.world.gen.feature.WorldGenLakes; import net.minecraftforge.common.BiomeManager.BiomeType; public class BiomeVolcano extends BiomeHills{ private WorldGenLakes LAKES = new WorldGenLakes(Blocks.LAVA); public BiomeVolcano() { super(BiomeHills.Type.NORMAL, new BiomeProperties("Volcano").setTemperature(10.0F).setBaseHeight(1.0F).setHeightVariation(0.1F)); this.topBlock = Blocks.COAL_BLOCK.getDefaultState(); this.fillerBlock = MWBlocks.LAVA_ROCK.getDefaultState(); this.spawnableCreatureList.clear(); this.spawnableMonsterList.add(new Biome.SpawnListEntry(EntityMagmaCube.class, 10, 1, 4)); } @Override public int getSkyColorByTemp(float currentTemperature) { return 0xFF0000; } @Override public void decorate(World worldIn, Random rand, BlockPos pos) { super.decorate(worldIn, rand, pos); if(net.minecraftforge.event.terraingen.TerrainGen.decorate(worldIn, rand, pos, net.minecraftforge.event.terraingen.DecorateBiomeEvent.Decorate.EventType.LAKE_WATER)) if (rand.nextInt(5) == 0) { int i = rand.nextInt(16) + 8; int j = rand.nextInt(16) + 8; BlockPos blockpos = worldIn.getHeight(pos.add(i, 0, j)).up(); LAKES.generate(worldIn, rand, blockpos); } if (rand.nextInt(2) == 0) { int i = rand.nextInt(16) + 8; int j = rand.nextInt(16) + 8; BlockPos blockpos = worldIn.getHeight(pos.add(i, 0, j)).up(); new WorldGenVolcano().generate(worldIn, rand, blockpos); } } public void genTerrainBlocks(World worldIn, Random rand, ChunkPrimer chunkPrimerIn, int x, int z, double noiseVal) { this.generateBiomeTerrain(worldIn, rand, chunkPrimerIn, x, z, noiseVal); } } And this is how i register it public static Biome VOLCANO; VOLCANO = new BiomeVolcano(); VOLCANO.setRegistryName("volcano"); //In the registration event event.getRegistry().register(VOLCANO); //In the registration event BiomeManager.addBiome(BiomeType.DESERT, new BiomeManager.BiomeEntry(VOLCANO, 5));

If you want to override a vanilla loot table you can also make your own loot table (wich is a copy of the vanilla one + the items of your mod) and then in that event set your loot table as the table of the event. For example, i do this to override the vanilla mineshaft chest loot table. I create my own mineshaft chest loot table by doing this public static ResourceLocation CHESTS_ABANDONED_MINESHAFT; CHESTS_ABANDONED_MINESHAFT = LootTableList.register(new ResourceLocation(MW.MODID, "abandoned_mineshaft")); and i call this from the init method in main mod file. This will assume that in your assets folder you have a folder called "loot_tables" and inside that folder you have the loot table you're looking for (in this case "abandoned_mineshaft"). That will be the replaced loot table (so the game will load this instead of the vanilla one). For example look at this loot table { "pools": [ { "name": "abandoned_mineshaft_1", "rolls": 1, "entries": [ { "type": "item", "entryName": "golden_apple", "name": "minecraft:golden_apple", "weight": 20 }, { "type": "item", "entryName": "enchanted_golden_apple", "name": "minecraft:golden_apple", "weight": 1, "functions": [ { "function": "set_data", "data": 1 } ] }, { "type": "item", "name": "minecraft:name_tag", "weight": 30 }, { "type": "item", "name": "minecraft:book", "weight": 10, "functions": [ { "function": "enchant_randomly" } ] }, { "type": "item", "name": "minecraft:iron_pickaxe", "weight": 5 }, { "type": "item", "name": "mw:ruby", "weight": 20, "functions": [ { "function": "set_count", "count": { "min": 1, "max": 4 } } ] }, { "type": "item", "name": "mw:sapphire", "weight": 20, "functions": [ { "function": "set_count", "count": { "min": 1, "max": 4 } } ] }, { "type": "empty", "weight": 5 } ] }, { "name": "abandoned_mineshaft_2", "rolls": { "min": 2, "max": 4 }, "entries": [ { "type": "item", "name": "minecraft:iron_ingot", "functions": [ { "function": "set_count", "count": { "min": 1, "max": 5 } } ], "weight": 10 }, { "type": "item", "name": "minecraft:gold_ingot", "functions": [ { "function": "set_count", "count": { "min": 1, "max": 3 } } ], "weight": 5 }, { "type": "item", "name": "minecraft:redstone", "functions": [ { "function": "set_count", "count": { "min": 4, "max": 9 } } ], "weight": 5 }, { "type": "item", "name": "minecraft:dye", "functions": [ { "function": "set_data", "data": 4 }, { "function": "set_count", "count": { "min": 4, "max": 9 } } ], "weight": 5 }, { "type": "item", "name": "minecraft:diamond", "functions": [ { "function": "set_count", "count": { "min": 1, "max": 2 } } ], "weight": 3 }, { "type": "item", "name": "minecraft:coal", "functions": [ { "function": "set_count", "count": { "min": 3, "max": 8 } } ], "weight": 10 }, { "type": "item", "name": "minecraft:bread", "functions": [ { "function": "set_count", "count": { "min": 1, "max": 3 } } ], "weight": 15 }, { "type": "item", "name": "minecraft:melon_seeds", "functions": [ { "function": "set_count", "count": { "min": 2, "max": 4 } } ], "weight": 10 }, { "type": "item", "name": "minecraft:pumpkin_seeds", "functions": [ { "function": "set_count", "count": { "min": 2, "max": 4 } } ], "weight": 10 }, { "type": "item", "name": "minecraft:beetroot_seeds", "functions": [ { "function": "set_count", "count": { "min": 2, "max": 4 } } ], "weight": 10 } ] }, { "name": "abandoned_mineshaft_3", "rolls": 3, "entries": [ { "type": "item", "name": "minecraft:rail", "functions": [ { "function": "set_count", "count": { "min": 4, "max": 8 } } ], "weight": 20 }, { "type": "item", "name": "minecraft:golden_rail", "functions": [ { "function": "set_count", "count": { "min": 1, "max": 4 } } ], "weight": 5 }, { "type": "item", "name": "minecraft:detector_rail", "functions": [ { "function": "set_count", "count": { "min": 1, "max": 4 } } ], "weight": 5 }, { "type": "item", "name": "minecraft:activator_rail", "functions": [ { "function": "set_count", "count": { "min": 1, "max": 4 } } ], "weight": 5 }, { "type": "item", "name": "minecraft:torch", "functions": [ { "function": "set_count", "count": { "min": 1, "max": 16 } } ], "weight": 15 } ] } ] } This is the vanilla abandoned_mineshaft loot table plus some rolls for my mod items, so in game in mineshafts i can find mod items too in chests. Finally, to load this table instead of the vanilla one you'll have to catch the LootTableLoadEvent and set the table to your own table. public void onLootTableLoad(LootTableLoadEvent event) { if(event.getName().equals(LootTableList.CHESTS_ABANDONED_MINESHAFT)) { event.setTable(event.getLootTableManager().getLootTableFromLocation(MWLootTables.CHESTS_ABANDONED_MINESHAFT)); } } In game, when you'll open a mineshaft chest it will load your loot table (the one showed up) instead of the vanilla one and so yuour mod items will have a chance to be in that cehst. Hope this is clear :)

That's unfortunate, i hope there will be a way to specify the Recipe Book tab too soon for any block/item that is not in the vanilla creative tabs

Thank you. Infact having this file { "type": "minecraft:crafting_shaped", "pattern": [ "AAA", "ASA", "AAA" ], "key": { "S": { "item": "mw:ruby" }, "A": { "item": "minecraft:stone", "data": 0 } }, "result": { "item": "mw:ruby_ore", "data": 0 } } Now the recipe work. But i've noticed is not going in the proper tab on the recipe book. For example, this recipe refers to a building block, how can i display it in that tab and not only in the "all recipes" tab?

Ok, so if a block has a variant but you don't want to use a specific one you still need to specify it? That means, if the block has 10 variants, that you have to specify 10 recipes changing the data value every time?

Woops. By the way that comma was not the problem, i removed that but the recipe is still not working. I guess i must register it before but can't figure out how

Yes, i said "modid" to be generic, but the actual path is assets/mw/recipes (since mw is my mod id). Other things like blocks and items works as well so i guess is not a wrong folder path

I have this json recipe in assets/modid/recipes folder { "type": "minecraft:crafting_shaped", "pattern": [ "AAA", "ASA", "AAA" ], "key": { "S": { "item": "mw:ruby" }, "A": [ { "item": "minecraft:stone", }, ] }, "result": { "item": "mw:ruby_ore", "data": 0 } } But in game is not working, so i guess i have to register it. So how can i register a crafting recipe in 1.12? :)

Ok, i get it But there is at least a way to get the mod id of the dimension's mod? So i can make that string by my own?

Pretty self explaining: how can i get the dimension name based on the provider or the id? I know that doing getDimensionType().getName() i can have something like "Overworld", but what i want is something like "minecraft:overworld" or "somemod:dimension" (if is a dimension from a mod). How can i do that?

I have a GUI with some buttons in it, and when i click those buttons i want the gui to change appearance (basically some buttons will be replaced with others). How can i do so that the gui automatically refresh without closing it and reopening it to see the changes? Also i've noticed that the gui repaint itself when i resize the window, doing something like this How can i made so the gui doesn't do this every time i resize?

So i should just send a message (via SimpleNetworkWrapper) to the client with all the necessary informations (taken from the server) and inside the message decide if open the Gui or not?
