I assume you have to override getBoundingBox in Block

There's also getCollisionBoxes or something like that, that returns a list.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

By looking at BlockStairs and going "might this method be involved somehow?" I found:

 

collisionRayTrace

i have been using a custom ray trace from previous version,  maybe it's changes.   But , it seems only the Entity  ignores the collision boxes

    @Nullable
    public RayTraceResult collisionRayTrace(IBlockState blockState, World worldIn, BlockPos pos, Vec3d start, Vec3d end)
    {
        List<RayTraceResult> list = Lists.<RayTraceResult>newArrayList();

        for (AxisAlignedBB axisalignedbb : getCollisionBoxList(this.getActualState(blockState, worldIn, pos)))
        {
            list.add(this.rayTrace(pos, start, end, axisalignedbb));
        }

        RayTraceResult raytraceresult1 = null;
        double d1 = 0.0D;

        for (RayTraceResult raytraceresult : list)
        {
            if (raytraceresult != null)
            {
                double d0 = raytraceresult.hitVec.squareDistanceTo(end);

                if (d0 > d1)
                {
                    raytraceresult1 = raytraceresult;
                    d1 = d0;
                }
            }
        }

        return raytraceresult1;

There was a change :

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

 

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

 

I should have caught this while updating from 10.

 

USE THE @Override!
