[1.16]How to hide the block's CollisionBoundingBox in 1.16?

Recommended Posts

In 12.2, there was a method can be Override to high the block's CollisionBoundingBox

@Override
public AxisAlignedBB getCollisionBoundingBox(IBlockState blockState, World worldIn, BlockPos pos) {
    return Block.NULL_AABB;
}

 

But I can't find this method in Blocks anymore in 1.16,so how can I hide the block's CollisionBoundingBox in 1.16?

You can either return an empty VoxelShape in getShape or cancel DrawHighlightEvent.HighlightBlock if you want the block to keep its collision.

sorry about that I a noob modder, I don't know how to cancel an event, I try to write it like this but it doesn't work

    @SubscribeEvent
    public static void lookToBlock(DrawHighlightEvent.HighlightBlock event){
        event.setCanceled(true);
    }

What should I do to cancel it?

looks good. is the event called?
how do you register the event listener

Well....here is code...

    @Mod.EventBusSubscriber()
    public static class MyStaticClientOnlyEventHandler {
     @SubscribeEvent
         public static void lookToBlock(DrawHighlightEvent.HighlightBlock event){
             event.setCanceled(true);
         }
    }

The problem is seems I canceled all highlightevent in the world. Is it possible to only cancel my mod's block's highlight?

I'm not sure, but I think you need to include your Mod ID here

would be useful but shouldn't be the problem
And I have no idea where you can get the world for it, because you only get a BlockRayTraceResult from the event and this does not contain a world
Edit: you can get a ClientWorld from the WorldRenderer so you can use World#getBlockState to check whether the block at that point is your block

If only there was some documentation...

https://mcforge.readthedocs.io/en/1.16.x/events/intro/

 

That said, middangeardim, I'm not sure why you're going about doing this with events when the "method to override" path is available to you and all you need to do is return an empty VoxelShape instead of a null one.

solution for the world is you can get it from Minecraft (Minecraft#getInstance().level)
your event should work, I cannot reproduce your error after trying something

Unfortunatly, I'm designing a cropblock. If I return an empty VoxelShape, then how can I break it?(I can't even touch it?😂)

There are different methods in the block class that return a VoxelShape (getInteractionShape, getCollisionShape, getRenderShape, getShape, ...).
you should use getRenderShape but I'm not sure (test)

actually there is only one method about shape in #Block

"makeCuboidShape" and I think it doesn't help🤔

the getRenderShape means I have to change the block into a TileEntity Block

no, you have to overwrite the method in your Block class

But I already Override the getShape method in the class because the cropsblock need it

    public VoxelShape getShape(BlockState state, IBlockReader worldIn, BlockPos pos, ISelectionContext context) {
        return SHAPES[state.get(this.getAgeProperty())];
    }

Is it possible to override another method to get the shape again? All I want is cancel the highlight, not to change the shape of the cropsblock(My brain totally mess up😱)

 

here is the whole code in the class

public class original_pumpkin_cropblock extends CropsBlock {
    private static final VoxelShape[] SHAPES = new VoxelShape[]{Block.makeCuboidShape(5.0D, 0.0D, 5.0D, 10.0D, 4.0D, 10.0D),
                                                                Block.makeCuboidShape(6.0D, 0.0D, 6.0D, 11.0D, 7.0D, 11.0D),
                                                                Block.makeCuboidShape(6.0D, 0.0D, 6.0D, 11.0D, 9.0D, 11.0D),
                                                                Block.makeCuboidShape(3.0D, 0.0D, 3.0D, 13.0D, 9.0D, 13.0D),
                                                                Block.makeCuboidShape(3.0D, 0.0D, 3.0D, 13.0D, 9.0D, 13.0D),
                                                                Block.makeCuboidShape(3.0D, 0.0D, 3.0D, 13.0D, 9.0D, 13.0D),
                                                                Block.makeCuboidShape(0.0D, 0.0D, 0.0D, 16.0D, 12.0D, 16.0D),
                                                                Block.makeCuboidShape(0.0D, 0.0D, 0.0D, 16.0D, 12.0D, 16.0D)};

    public original_pumpkin_cropblock() {
        super(AbstractBlock.Properties.create(Material.PLANTS).doesNotBlockMovement().tickRandomly().zeroHardnessAndResistance().sound(SoundType.CROP));
    }

    @Override
    protected IItemProvider getSeedsItem() {
        return ItemRegistry.originalPumpkinSeed.get();
    }

    public VoxelShape getShape(BlockState state, IBlockReader worldIn, BlockPos pos, ISelectionContext context) {
        return SHAPES[state.get(this.getAgeProperty())];
    }

    @Override
    protected int getBonemealAgeIncrease(World worldIn) {
        return MathHelper.nextInt(worldIn.rand, 1, 2);
    }
}

So I think you should use the event because if you overwrite getShape in the block class you can no longer interact with it
