[1.17.x] How to make a block that can become indestructible when I apply some powder on it ?


Recommended Posts


I'm a newbie in the Minecraft modding but I know the Java's basics. I use Intellij IDEA. The mod is intended for 1.17.x

I'm making a sort of Aether Mod (in order to train). Currently, I am creating a block which can become indestructible when I apply some Luminite powder (a new crystal transformed into powder). This block is called Urzil and it will be used in the dungeon where it is, by default, indestructible.

My question is how should I proceed to code that ? Should I look the Redstone-Lamp-Block JavaClass and "copy" the code or should I search through the tons of Minecraft code until I find the good method per example ?

I have created an abstract JavaClass called "ChargeableBlocks"  (in a folder named "Common") which contains the Urzil feature. As a matter of fact, I planned to create other ones for more dungeons. Then, I will place the UrzilClass in the same folder

I watched some video (TurtyWurty and Kaupenjoe) but I understand nothing that can help me.

The part of ChargeableBlock's JavaClass below is obviously incomplete. I haven't coded the Luminite Powder yet.

If someone can help (or correct) me please. I'm lost




package fr.vat.mymod.common.block;

import net.minecraft.core.BlockPos;
import net.minecraft.world.InteractionHand;
import net.minecraft.world.InteractionResult;
import net.minecraft.world.entity.player.Player;
import net.minecraft.world.level.Level;
import net.minecraft.world.level.block.Block;
import net.minecraft.world.level.block.state.BlockBehaviour;
import net.minecraft.world.level.block.state.BlockState;
import net.minecraft.world.level.block.state.StateDefinition;
import net.minecraft.world.level.block.state.properties.BooleanProperty;
import net.minecraft.world.phys.BlockHitResult;

public abstract class ChargeableBlocks extends Block {
    public static final BooleanProperty CHARGED = BooleanProperty.create("charged");

    public ChargeableBlocks(BlockBehaviour.Properties properties) {
        this.registerDefaultState(this.defaultBlockState().setValue(CHARGED, Boolean.valueOf(false)));

    protected void createBlockStateDefinition(StateDefinition.Builder<Block, BlockState> pBuilder) {

    public InteractionResult use(BlockState pState, Level pLevel, BlockPos pPos, Player pPlayer, InteractionHand pHand, BlockHitResult pHit) 	{

    • That's what's so odd. Because I shift-clicked to get the file path & it literally is the same exact thing: (copy + pasted from folder) "C:\Program Files\Java\jdk-17\bin\javaw.exe"
    • updated a few mods and now my pack won't load https://paste.ee/p/0sUrp
    • I have installed Forge 1000 times and in different versions, but every time I enter a server or world, it loads the entire square and then it says ''Saving world''. After that, Minecraft closes and the launcher opens with a window displaying error code ''-1''. I don't even have any mods installed, it doesn't let me join any world or server. I contacted Minecraft support, and they told me to talk to you. I hope you can help me with this issue, I'm waiting for your response.
    • I'm trying to make a Event that is fired if a Player is swimming. Here is the Event Class: public class PlayerSwimEvent extends PlayerEvent { public PlayerSwimEvent(Player player) { super(player); } } Here is the Hooks (similar to ForgeHooks Class) that has Methods for the Events: public class EventHooks { public static void onPlayerSwim(Player player) { MinecraftForge.EVENT_BUS.post(new PlayerSwimEvent(player)); } } And here is the Mixin Class: @Mixin(value = Player.class) public class MixinPlayerSwimEvent { @Inject(method = "isSwimming", at = @At("HEAD")) public boolean isSwimming(CallbackInfoReturnable<Boolean> cir) { Player player = null; if (!player.getAbilities().flying && !player.isSpectator()) { EventHooks.onPlayerSwim(player); } return cir.getReturnValue(); } } My Issue is now that I don't get it to work because of the missing Parameter Player. Can someone help with this?
