Adding collision boxes

[blinky000]

I added

}

    public void addCollisionBoxToList(IBlockState state, World worldIn, BlockPos pos, AxisAlignedBB entityBox, List<AxisAlignedBB> collidingBoxes, @Nullable Entity entityIn)
    {

         System.out.println("---------------------------------------here");

}
      

 

to my custom block, but the method is never called.  Using the debugger , i saw when a stair block is placed, that method is called.  what am i missing?

I copied that method from BlockStairs, it had no Override.  There is no method in the Block.class of that type, there is :

 

@Override
    protected static void addCollisionBoxToList(BlockPos pos, AxisAlignedBB entityBox, List<AxisAlignedBB> collidingBoxes, @Nullable AxisAlignedBB blockBox)

 

I get ther error:

The method addCollisionBoxToList(BlockPos, AxisAlignedBB, List<AxisAlignedBB>, AxisAlignedBB) of type YobBlockArrowLoopTop must override or implement a supertype method

[Draco18s]

You can't override static methods.

[blinky000]

Then im back where i started.  I want to have multiple collision boxes.  I can find nothing in Block to override.  looking at BlockStairs hasn't helped

i don't know where to add to the collision list

[Draco18s]

You mean the non-static method just above it that invokes the static one?

addCollisionBoxToList?

[blinky000]

I tried that also, gave the the same error on Override

[Draco18s]

That's funny.

[blinky000]

Wow, i just did your test, worked fine, what have i done to the custom block?

[blinky000]

It's a bad import somewhere

BAD import com.sun.xml.internal.stream.Entity;

 

 

GOOD import net.minecraft.entity.Entity;
