currently I have something like this

package me.jestem.mixin;

import net.minecraft.core.BlockPos;
import net.minecraft.server.MinecraftServer;
import net.minecraft.world.entity.player.Player;
import net.minecraft.world.level.Level;
import net.minecraft.world.level.block.state.BlockState;
import org.spongepowered.asm.mixin.Mixin;
import org.spongepowered.asm.mixin.injection.At;
import org.spongepowered.asm.mixin.injection.Inject;

@Mixin(MinecraftServer.class)
public class TrappedChestBlockMixin {
    @Inject(method = "onUse", at = @At("HEAD"))
    private void onOpen(BlockState state, BlockPos pos, Level level, Player player) {
        // This code is injected into the start of MinecraftServer.loadLevel()V
    }
}

but the onUse doesn't exist, or am I doing something wrong?

There's an event for block use, UseBlockCallback

Well you're also targeting MinecraftServer.class

#

In a mixin called TrappedChestBlockMixin, so I don't assume you intended to target MinecraftServer

oh, and another thing - How can I get the items in the chest?

@Override
    public void onInitialize() {

        UseBlockCallback.EVENT.register((player, world, hand, hitResult) -> {
            BlockPos pos = hitResult.getBlockPos();
            if (world.getBlockState(pos).getBlock() instanceof TrappedChestBlock trappedChestBlock) {
                if(trappedChestBlock.???){
                    world.explode(null, pos.getX() + 0.5, pos.getY() + 0.5, pos.getZ() + 0.5,
                            4.0f, Level.ExplosionInteraction.TNT);
                    return InteractionResult.SUCCESS;
                }
            }
            return InteractionResult.PASS;
        });

        LOGGER.info("Hello Fabric world!");
    }

I tried looking at TrappedChestBlock.class but didn't find anything, same with ChestBlock.class and only getItems() in ChestBlockEntity.class but I have no idea what to do

You need to get the block entity from the level at the same position

I'm pretty new to modding and java in general, how do I do this?
