I have a NullPointerException but I don’t know where

[TokiiWalkie]

Hello, I am rpetty new in minecraft mod developpment, and I have plenty of errors. I’m trying to develop a block that increments or reduce its PLATFORM_NUMBER integer value.

 

All was right until I had the last function (when there’s a click , it increments or reduces a value), and when I try to launch my game, it crashes.

 

Here’s my code :

 

public class PlatformIndicatorBlock extends Block {

    public  final IntegerProperty PLATFORM_NUMBER = IntegerProperty.create("number", 0, 20);

    public PlatformIndicatorBlock() {
        super(AbstractBlock.Properties.create(Material.CLAY, MaterialColor.LIGHT_BLUE)
                .hardnessAndResistance(2f, 6f)
                .harvestTool(ToolType.PICKAXE)
                .harvestLevel(1)
                .sound(SoundType.STONE));

        this.setDefaultState(this.getDefaultState().with(PLATFORM_NUMBER, 0));
    }

  // I tried to add @Nullable there, but it makes nothing
  
    @Override
    protected void fillStateContainer(@Nullable StateContainer.Builder<Block, BlockState> builder) {
        builder.add(BlockStateProperties.HORIZONTAL_FACING, PLATFORM_NUMBER);
    }

    @Override
    public BlockState getStateForPlacement(BlockItemUseContext ctx) {
        return (BlockState) this.getDefaultState().with(BlockStateProperties.HORIZONTAL_FACING, ctx.getPlacementHorizontalFacing().getOpposite());
    }

    @Override
    public void onBlockClicked(BlockState state, World worldIn, BlockPos pos, PlayerEntity player) {
        if (player.isSneaking()) {

            if (state.get(PLATFORM_NUMBER) == 0) {
                return;
            } else {
                worldIn.setBlockState(pos, state.with(PLATFORM_NUMBER, state.get(PLATFORM_NUMBER) - 1));
            }
        } else {

            if (state.get(PLATFORM_NUMBER) == 0) {
                return;
            } else {
                worldIn.setBlockState(pos, state.with(PLATFORM_NUMBER, state.get(PLATFORM_NUMBER) + 1));
            }
        }
    }
}

 

Here’s my stacktrace :

      I don’t add the second crash report, because it basically says that my block is not registered, but it is not registered because of this error, so I think when this problem will be recovered it will be ok

 

So thank you

Line 28 of PlatformIndicatorBlock.

 

[TokiiWalkie]

Maybe can you help me solving this issue please? It’s been a few days I’m on it, and I cannot solve it

this.setDefaultState(this.getDefaultState().with(PLATFORM_NUMBER, 0));

you will set the default state and inside you will get the default state?

use:

this.setDefaultState(this.stateContainer.getBaseState().with(PLATFORM_NUMBER, 0));

I think that's your mistake but I'm not sure because I don't know if it's line 28

[TokiiWalkie]

no it still does not work

[TokiiWalkie]

Here is my code, I have done what Luis said, but nothing. I have also changed "AbstractBlock.Properties" to "Block.Properties", since I’m extending Block and not AbstractBlock.

 

package fr.twlk.therailwaysproject.content.blocks;

import net.minecraft.block.AbstractBlock;
import net.minecraft.block.Block;
import net.minecraft.block.BlockState;
import net.minecraft.block.SoundType;
import net.minecraft.block.material.Material;
import net.minecraft.block.material.MaterialColor;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.item.BlockItemUseContext;
import net.minecraft.state.IntegerProperty;
import net.minecraft.state.Property;
import net.minecraft.state.StateContainer;
import net.minecraft.state.properties.BlockStateProperties;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.util.Direction;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.IBlockReader;
import net.minecraft.world.World;
import net.minecraftforge.common.ToolType;

import javax.annotation.Nullable;

public class PlatformIndicatorBlock extends Block {

    public  final IntegerProperty PLATFORM_NUMBER = IntegerProperty.create("number", 0, 20);

    public PlatformIndicatorBlock() {
      // Line 29  
      super(Block.Properties.create(Material.CLAY, MaterialColor.LIGHT_BLUE)
                .hardnessAndResistance(2f, 6f)
                .harvestTool(ToolType.PICKAXE)
                .harvestLevel(1)
                .sound(SoundType.STONE));

        this.setDefaultState(this.stateContainer.getBaseState().with(PLATFORM_NUMBER, 0));
    }

    @Override
    protected void fillStateContainer(@Nullable StateContainer.Builder<Block, BlockState> builder) {
	// Line 40
      builder.add(PLATFORM_NUMBER, BlockStateProperties.HORIZONTAL_FACING);
    }

    @Override
    public BlockState getStateForPlacement(BlockItemUseContext ctx) {
        return (BlockState) this.getDefaultState().with(BlockStateProperties.HORIZONTAL_FACING, ctx.getPlacementHorizontalFacing().getOpposite());
    }

    @Override
    public void onBlockClicked(BlockState state, World worldIn, BlockPos pos, PlayerEntity player) {
        if (player.isSneaking()) {
            if (state.get(PLATFORM_NUMBER) == 0) {
                return;
            } else {
                worldIn.setBlockState(pos, state.with(PLATFORM_NUMBER, state.get(PLATFORM_NUMBER) - 1));
            }
        } else {
            if (state.get(PLATFORM_NUMBER) == 0) {
                return;
            } else {
                worldIn.setBlockState(pos, state.with(PLATFORM_NUMBER, state.get(PLATFORM_NUMBER) + 1));
            }
        }
    }
}

 

The crash report is the same

store the facing in a field and add it to setDefaultState

beacuse you add it to stateContainer but you never set the base facing so minecraft dont know how to set the block

this is the last mistake that it could be and that I find in your code

 

i try to create your block in my mod and see if it works

[TokiiWalkie]

So it does not crash anymore, so thank you

A last question : When I click on the block, I cannot interract with it, so do I need to add a tileentity?

Typing mistake

use onBlockActivated instead of onBlockClicked
