Make a block two blocks high.

[Raycoms]

I have a custom scarecrow which has a collission box which is two blocks high.

But most entities think my block is just one high and get stuck in it.

Is there a fix for this?

There is a method in Block that allows you to edit the collision boxes. Look at BlockCactus for an example.

[Draco18s]

Please don't use

BlockContainer 

or

ITileEntityProvider

All you need to do is override

hasTileEntity

and

getTileEntity

supplied by the Block class.

[Raycoms]

Even if this is 1.8.9 code and I have a custom GUI and an inventory in the block?

 

(getTileEntity doesn't work).

 

Also @Animefan8888 the cactus didn't help me a lot since it has various blocks.

[Draco18s]

Even if this is 1.8.9 code and I have a custom GUI and an inventory in the block?

 

I believe so.  Any reason you haven't updated to 1.9.4 or 1.10.2?

[Raycoms]

Our mod is pretty big and will need some time to update.

[Animefan8888]

Also @Animefan8888 the cactus didn't help me a lot since it has various blocks.

Mainly the getCollisionBoundingBox(...), getSelectedBoundingBox(...), isFullCube(...), abd isOpaqueCube (...).

[Raycoms]

I added all this but entities still try to path over it. (Minecraft entities as well as custom entities)

 

@Override
    public void setBlockBoundsBasedOnState(IBlockAccess worldIn, BlockPos pos)
    {
        setBlockBounds((float)START_COLLISION, (float)BOTTOM_COLLISION, (float)START_COLLISION, (float)END_COLLISION, (float)HEIGHT_COLLISION, (float)END_COLLISION);
    }

    @Override
    public AxisAlignedBB getCollisionBoundingBox(World worldIn, BlockPos pos, IBlockState state)
    {
        this.setBlockBoundsBasedOnState(worldIn, pos);
        this.maxY = 2D;
        return super.getCollisionBoundingBox(worldIn, pos, state);
    }

    @Override
    public boolean isFullCube()
    {
        return false;
    }

 

and that is basically what walls etc do as well.

[Animefan8888]

Override isPassable().

[Raycoms]

Just did: Still not working.

 

    @Override
    public boolean isPassable(IBlockAccess worldIn, BlockPos pos)
    {
        return false;
    }

[Animefan8888]

Just did: Still not working.

 

    @Override
    public boolean isPassable(IBlockAccess worldIn, BlockPos pos)
    {
        return false;
    }

Just to make this easier make a private static AxisAlignedBB with the size you want and return that in getCollisionBoundingBox(...)

[Raycoms]

When I do this he stops rendering the scarecrow and I am able to pass through it.

(I still see the bounding box thoe)

 

 

    private static final double BOTTOM_COLLISION = 0.0;

    /**
     * Start of the collision box at x and z.
     */
    private static final double START_COLLISION = 0.1;

    /**
     * End of the collision box.
     */
    private static final double END_COLLISION = 0.9;

    /**
     * Height of the collision box.
     */
    private static final double HEIGHT_COLLISION = 2.5;

    private static AxisAlignedBB boundingBox = new AxisAlignedBB(START_COLLISION, BOTTOM_COLLISION, START_COLLISION, END_COLLISION, HEIGHT_COLLISION, END_COLLISION);

[Raycoms]

Edited it a bit and it renders now correctly, but still.

All the entities get stuck in it.

 

    @Override
    public AxisAlignedBB getCollisionBoundingBox(World worldIn, BlockPos pos, IBlockState state)
    {
        this.setBlockBoundsBasedOnState(worldIn, pos);
        this.maxY = 2D;
        return new AxisAlignedBB(pos.getX() - START_COLLISION, pos.getY() - BOTTOM_COLLISION, pos.getZ() - START_COLLISION, pos.getX() + END_COLLISION, pos.getY() + HEIGHT_COLLISION,pos.getZ() + END_COLLISION);
    }

[Draco18s]

Minecraft does not really like blocks larger than 1x1x1.  The fence with it's 1.5 high bounding box is pretty much the maximum that Minecraft will treat correctly.

 

I've not tested bounding boxes larger than that, but I suspect that if it's giving you trouble, that is why.  You need to use a second technical block, the way Beds work.

[jabelar]

One reason I believe that Minecraft wisely limits both the block and entity bounding boxes is to aid path-finding (i.e. the logic to let entities move around avoiding blocks). Path-finding gets exponentially more difficult (more buggy and lower performance) if you allow arbitrary size and shape of the bounding boxes of either.

[jeffryfisher]

You need to use a second technical block, the way Beds work.

Also look at how doors stand 2-high, rotate both halves when right-clicked, and can be broken by hitting either top or bottom.
