I have a friend who wants to make a mod that places blocks beneath your feet

[20ChenM]

I have a friend who wants to make a mod that places blocks beneath your feet but his code has errors. I do not know how to help him since i am new to 1.15.2 modding so I am coming to the forums asking for help.

 

 

 

His Code:

 

Locate class:

import net.minecraft.block.Block;

import net.minecraft.block.BlockState;

import net.minecraft.block.Blocks;

import net.minecraft.block.material.Material;

import net.minecraft.client.Minecraft;

import net.minecraft.entity.LivingEntity;

import net.minecraft.fluid.IFluidState;

import net.minecraft.util.math.BlockPos;

import net.minecraft.entity.Entity;

import net.minecraft.entity.player.*;

import net.minecraft.item.Item;

import net.minecraft.world.World;

import net.minecraftforge.fml.RegistryObject;

import net.minecraftforge.registries.DeferredRegister;

import net.minecraftforge.registries.ForgeRegistries;

 

public class Locate {

   public void isAirBelow(BlockPos pos)

   {

       EntityPlayer player = event.player;

       BlockPos posBelow = player.getPosition().down();

       BlockState blockStateBelow = player.world.getBlockState(posBelow);

       Block below = blockStateBelow.getBlock();

 

       if(below.equals(Material.AIR)) {

           world.setBlock(blockStateBelow, Blocks.COBBLESTONE);

       }

   }

}

 

main class:

 

import java.util.stream.Collectors;

 

// The value here should match an entry in the META-INF/mods.toml file

@Mod("Scaffold")

public class Scaffold

{

   // Directly reference a log4j logger.

   private static final Logger LOGGER = LogManager.getLogger();

 

   public Scaffold() {

       // Register the setup method for modloading

       FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);

       FMLJavaModLoadingContext.get().getModEventBus().addListener(this::doClientStuff);

 

       // Register ourselves for server and other game events we are interested in

       MinecraftForge.EVENT_BUS.register(this);

   }

 

   private void setup(final FMLCommonSetupEvent event)

   {

       // some preinit code

       LOGGER.info("HELLO FROM PREINIT");

       LOGGER.info("DIRT BLOCK >> {}", Blocks.DIRT.getRegistryName());

   }

 

   private void doClientStuff(final FMLClientSetupEvent event) {

       // do something that can only be done on the client

       LOGGER.info("Got game settings {}", event.getMinecraftSupplier().get().gameSettings);

   }

}

There is no event parameter. Also, please tell your friend to open a thread post of his own so we do not need to go through a middleman.

 

Setting a block beneath the player's feet would probably need to be handled in a PlayerTickEvent. However, doing this probably isn't a good idea as it will cause a bunch of lag and make it impossible to go down.

are you trying to develop scaffold hacks lol

More like that method (and that class!) are never referenced anywhere else.

You can do this by the Event: LivingEntity.LivingJumpEvent

Example:

@SubscribeEvent
public static void onJump(LivingEvent.LivingJumpEvent event) {
    LivingEntity player = event.getEntityLiving();
    World world = player.getEntityWorld();
    world.setBlockState(player.getPosition().add(0, 0, 0), YOUR_BLOCK.get().getDefaultState());
}

and it has to be in a class where you make your Events.

For this put this just above your class:

@Mod.EventBusSubscriber(modid = your_mod_id, bus = Mod.EventBusSubscriber.Bus.FORGE, value = Dist.CLIENT)

 

EDIT:if you want to have cobblestone replace YOUR_BLOCK with Blocks.COBBLESTONE

           and your_mod_ id with "Scaffold"

Or with the LivingTickEvent:

@SubscribeEvent
public static void onJump(TickEvent.PlayerTickEvent event){
    if (event.player.world.getBlockState(event.player.getPosition().add(0, -1, 0)) == Blocks.AIR.getDefaultState()){
        event.player.world.setBlockState(event.player.getPosition().add(0, -1, 0), Blocks.COBBLESTONE.getDefaultState());
    }
}

Please tell me if it worked.

Mod id can not be capitalized.

    World world = player.getEntityWorld();
    world.setBlockState(player.getPosition().add(0, 0, 0), YOUR_BLOCK.get().getDefaultState());
}

LivingJumpEvent is triggered whenever a living entity jump, and that includes livings like sheep, chickens, zombies..etc.

the default bus of annotation @Mod.EventBusSubscriber is forge already, and it should not be done only on client side.
