Recable

This code here makes it so that cobblestone instead drops stone if they are wearing the specific pickaxe, however I have found out there's a glitch with this, when a creeper explodes (and the explosion hits the cobblestone) it crashes the game, does anyone know how to fix this? @SubscribeEvent public void addBlockDrop1(HarvestDropsEvent event) { if (event.state.getBlock() == Blocks.cobblestone) { ItemStack holding = event.harvester.inventory.getStackInSlot(event.harvester.inventory.currentItem); if (holding != null && holding.getItem() instanceof FirePickaxe) { event.drops.clear(); event.drops.add(new ItemStack(Blocks.stone)); } } } Here's my crash log:

Okay thanks.

I guess so, but what about the ctrl key? Because I wanted multiple events, one for right click, one for shift + right click, and one for ctrl + right click?

Yeah and if they change their sneak key to C for example? Jesus.

How do I make it so that inside the onItemRightClick method, you must press, for example, CTRL and right click for the event to happen? I use this code to change blocks that are placed down into another block: @Override public boolean onBlockActivated(World worldIn, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumFacing side, float hitX, float hitY, float hitZ) { if (Keyboard.isKeyDown(Keyboard.KEY_RSHIFT) || Keyboard.isKeyDown(Keyboard.KEY_LSHIFT)) { worldIn.setBlockState(pos, ModBlocks.AdjustableLightBlockStage1.getDefaultState()); return super.onBlockActivated(worldIn, pos, state, playerIn, side, hitX, hitY, hitZ); } else if (Keyboard.isKeyDown(Keyboard.KEY_RCONTROL) || Keyboard.isKeyDown(Keyboard.KEY_LCONTROL)){ worldIn.setBlockState(pos, ModBlocks.AdjustableLightBlockFull.getDefaultState()); return super.onBlockActivated(worldIn, pos, state, playerIn, side, hitX, hitY, hitZ); } else { return false; } } This works well but I can't seem to get this code: if (Keyboard.isKeyDown(Keyboard.KEY_RSHIFT) || Keyboard.isKeyDown(Keyboard.KEY_LSHIFT)) { To work inside the onItemRightClick method..? How would I get this to work?

How would I make a timer? For example I right click my sword using the onItemRightClick method it then gives me strength 3 for 5 seconds, now how would I make it so this effect won't activate again even when right clicked for 15 seconds?

Oh I see thanks.

Does anyone know how I would switch an item to another item on right click? So like I wanted to make a twin type of sword so that one sword is more offensive (giving a strength potion effect) and one being more defensive (giving a resistance potion effect) however I know how to do all of the potion effects (I think) and how to create the swords, but what would I do to switch the sword you're currently using with it's other half in the same hot bar slot you had the other sword in?

Anyone can help??

So far I've made my TnT classes, both the blocks and the entity, using the java code that is, and so for I have it exploding correctly and I can change the radius of the explosion and fuse timer too, so that's perfect, however the texture won't work, and when I light it, it just goes invisible and still blows up after the correct amount of seconds. Here is my Blocks class: package com.TestMod.mod.blocks; import com.TestMod.mod.ModGlobal; import com.TestMod.mod.nukes.ModTestBlockTnt; import net.minecraft.block.Block; import net.minecraft.block.material.Material; import net.minecraftforge.fml.common.registry.GameRegistry; public class ModBlocks { public static Block TestBlockTnt; public static void initBlocks() { GameRegistry.registerBlock(TestBlockTnt = new ModTestBlockTnt("TestBlockTnt", Material.grass, 0, 0), "TestBlockTnt"); } } Here is my Block Rendering Class: package com.TestMod.mod.render; import com.TestMod.mod.MODGlobal; import com.TestMod.mod.blocks.ModBlocks; import com.TestMod.mod.init.ModBlocks; import com.TestMod.mod.ores.MODOres; import net.minecraft.block.Block; import net.minecraft.client.Minecraft; import net.minecraft.client.resources.model.ModelResourceLocation; import net.minecraft.item.Item; import net.minecraftforge.fml.common.registry.GameRegistry; public class MODBlockRender { public static void registerBlockRender() { regBlock(ModBlocks.TestBlockTnt); } public static void regBlock(Block block) { Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(Item.getItemFromBlock(block), 0, new ModelResourceLocation(MODGlobal.MOD_ID + ":" + block.getUnlocalizedName().substring(5), "inventory")); } } Here is my Client Proxy: package com.TestMod.mod.proxy; import com.TestMod.mod.blocks.ModBlock; import com.TestMod.mod.blocks.ModBlocks; import com.TestMod.mod.init.ModBlocks; import net.minecraft.client.resources.model.ModelBakery; import net.minecraft.client.resources.model.ModelResourceLocation; import net.minecraft.item.Item; import net.minecraft.util.ResourceLocation; import net.minecraftforge.client.model.ModelLoader; import net.minecraftforge.fml.common.event.FMLInitializationEvent; import net.minecraftforge.fml.common.event.FMLPostInitializationEvent; import net.minecraftforge.fml.common.event.FMLPreInitializationEvent; public class ClientProxy extends CommonProxy { public void preInit(FMLPreInitializationEvent preEvent) { super.preInit(preEvent); } public void init(FMLInitializationEvent event) { super.init(event); ModBlockRender.registerBlockRender(); ; ModBlocks.registerRenders(); } @Override public void registerModelBakery() { //Gears ModelBakery.registerItemVariants(Item.getItemFromBlock(ModBlocks.TestBlockTnt), new ResourceLocation ("mod:TestBlockTnt_top")); ModelBakery.registerItemVariants(Item.getItemFromBlock(ModBlocks.TestBlockTnt), new ResourceLocation ("mod:TestBlockTnt_bottom")); ModelBakery.registerItemVariants(Item.getItemFromBlock(ModBlocks.TestBlockTnt), new ResourceLocation ("mod:TestBlockTnt_side")); } public void postInit(FMLPostInitializationEvent postEvent) { super.postInit(postEvent); } } Here is my Blockstate json (Named: ' TestBlockTnt.json '): Here is my Block json (Named: ' TestBlockTnt.json '): Here is my Item json (Named: ' TestBlockTnt.json '):

Random random = new Random(); int Chance = random.nextInt(11) + 1; if (Chance == 1) { //Stuff Here } How would I make the above code be: "If chance is equal to 5, to 7 do this." For example I want to set a range of numbers like if the number is from 5 to 8 then do this, how would that be in code wise?

Okay thanks but with the list, what would I do to make it the item, the quantity and also the chance of getting that single item? For example: Diamonds, 1 (amount), (20% chance of dropping) Bread, 5 (amount), 50% (chance of dropping) Redstone, 3-7 (amount), 30% (chance of dropping)

Why not? It works with what I need, please tell me what the problem is?

Thanks for your help, I used a HarvestDropsEvent instead because I already knew how to use that, I just readjusted it to my needs.

What would be a good example of a list I need then? And what would I return?

@Override public List<ItemStack> getDrops(IBlockAccess world, BlockPos pos, IBlockState state, int fortune) { Random random = new Random(); int Chance = random.nextInt(4); if (Chance == 1) { return (List<ItemStack>) Items.arrow; } else if (Chance == 2) { return (List<ItemStack>) Items.apple; } else{ return null; } } Okay I did this now but how do I add the drop quantity for each individual item, and also is my current code correct?

I should have said this first but I tried using quantityDropped and if I put it to 7, it drops 7 different items rather than 7 diamonds?

This code makes it drop different item depending on the random number generated, which is half of what I want, the other half would be making the item it drops be more than if it's stack size is more than one, for example when it drops a diamond I want it to drop 1-5 diamonds and not just one diamond? public Item getItemDropped(IBlockState state, Random random, int fortune) { int Chance = random.nextInt(7) + 1; if (Chance == 1) { return Items.bread; } else if (Chance == 2) { return Items.gold_ingot; } else if (Chance == 3) { return Items.ender_pearl; } else if (Chance == 4) { return Items.diamond; } else if (Chance == 5) { return Items.blaze_rod; } else if (Chance == 6) { return Item.getItemFromBlock(ModBlocks.adjustable_light_block_full); } else if (Chance == 7) { return Item.getItemFromBlock(ModBlocks.ancient_brick_block); } else { return null; } }
