This seems like it should be straightforward. I have a campfire block, and I want players to take damage when they run into it. I copied this code directly from BlockCactus, but it doesn't work. Instead of taking damage, the player auto-jumps on top of the block.

 

    protected static final AxisAlignedBB CACTUS_COLLISION_AABB = new AxisAlignedBB(0.0625D, 0.0D, 0.0625D, 0.9375D, 0.9375D, 0.9375D);
    protected static final AxisAlignedBB CACTUS_AABB = new AxisAlignedBB(0.0625D, 0.0D, 0.0625D, 0.9375D, 1.0D, 0.9375D);

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

    @SideOnly(Side.CLIENT)
    public AxisAlignedBB getSelectedBoundingBox(IBlockState state, World worldIn, BlockPos pos)
    {
        return CACTUS_AABB.offset(pos);
    }

	@Override
    public void onEntityCollidedWithBlock(World worldIn, BlockPos pos, IBlockState state, Entity entityIn)
    {
        entityIn.attackEntityFrom(DamageSource.cactus, 1.0F);
    }

 

I saw a comment somewhere about using addCollisionBoxToList, so I played around with that a little. I didn't get anywhere with that. What do I need to do here?

Make the block shorter than 1 block tall.

You need to override Block#isFullCube to return false. This will stop players being pushed out of the block and stop them suffocating in the block.

I am using the AxisAlignedBB measurements shown in my original post. I copied them directly from BlockCactus.

I am already doing this. Sorry, I didn't include it in my original post.

I am such an idiot. I was testing in creative mode.
