1.12 problem with collision boxes and obj models

[blinky000]

Basically  , can you have  collision boxes on a obj model block?  what worked on a json model dosn't seem to be working I.

Oh, and the collision boxes are there,  i test by shooting arrows,   the player just seems to be hitting a full block.

I assume you have to override getBoundingBox in Block

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

[blinky000]

yes to both.     like i said arrow will hit/pass  the collision box correctly  it's just the player that won't

[blinky000]

the player only reacts to to Bounding Box

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

 

collisionRayTrace

[blinky000]

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!
