I want to make the bed has no collision when player wears a set of armor, so I extended `BedBlock` in my new `Block` class and overrided the method `Block#getCollisionShape` as below:

 

public class VanishingBedBlock extends BedBlock {
    public VanishingBedBlock(BedBlock block) {
        super(block.getColor(), Properties.from(block));
    }

    @Override
    public VoxelShape getCollisionShape(BlockState state, IBlockReader worldIn, BlockPos pos, ISelectionContext context) {
        Entity entity = context.getEntity();
        if(entity instanceof LivingEntity) {
            if(/*check item somehow*/) {
                return VoxelShapes.empty();
            }
        }
        return super.getCollisionShape(state, worldIn, pos, context);
    }
}

 

However, when I place the bed in Minecraft, there is only the outline of the bed when I'm not wearing the armor. The bed just goes invisible.

I'm quite sure it is the problem of this class since cancelling the overriding doesn't give any problem at all.

 

What should I do?

That's because beds are usually renderered through a TER. You need to create a TER by default for it tor render, or just change the render type to block to support it. Nothing to do with what you said.

Ok so I have no idea about what a TER is and does "change the render type" means overriding Block#getRenderType or something?

 

Edit: I just figured out what is TER. Sorry for that. So what do I do to create a TER?

Are you trying to make this work for vanilla bed or just for your custom bed? If you are trying to cancel the collision with vanilla bed thats not what Override is for. Look here for TER reference: https://mcforge.readthedocs.io/en/latest/tileentities/tesr/

Or just look at the vanilla bed block and BedTileEntityRenderer class to get and idea
