[1.15.2] Prevent Block Placement [SOLVED]

[Tikaji]

How do I go about preventing a block placement from happening on block activation? I currently have a block that has overridden onBlockActivated and it works as expected, however the block that is in the players hand is placed for a split second and then is removed, which then causes my itemstack to be decreased (I'm making the assumption that this is the default behavior of placing a block). I also looked at the EntityPlaceEvent and tried cancelling it, but I still got the same behavior. I would like to prevent that split second block placement and stack decrease.

Here is the onBlockActivated if it helps.

Spoiler

@Override
    public ActionResultType onBlockActivated(BlockState state, World worldIn, BlockPos pos,
        PlayerEntity player, Hand handIn, BlockRayTraceResult hit) {
        if (!worldIn.isRemote()) {
            ItemStack stack = player.getHeldItem(handIn);

            if (stack.isEmpty() && player.isSneaking()) {
                TileEntity tileEntity = worldIn.getTileEntity(pos);
                if (tileEntity instanceof SieveTile) {
                    SieveTile sieveTile = (SieveTile) tileEntity;
                    sieveTile.removeMesh(true);
                    return ActionResultType.SUCCESS;
                }
            }

            if (stack.getItem() instanceof MeshItem) {
                TileEntity tileEntity = worldIn.getTileEntity(pos);
                if (tileEntity instanceof SieveTile) {
                    SieveTile sieveTile = (SieveTile) tileEntity;
                    sieveTile.insertMesh(stack);
                    return ActionResultType.SUCCESS;
                }
            }

            if(stack.getItem() instanceof BlockItem) {
                BlockItem blockItem = (BlockItem)stack.getItem();
                if(SieveDrops.isBlockSiftable(blockItem.getBlock())) {
                    TileEntity tileEntity = worldIn.getTileEntity(pos);
                    if(tileEntity instanceof SieveTile) {
                        SieveTile sieveTile = (SieveTile)tileEntity;
                        sieveTile.insertSiftableBlock(stack);
                        return ActionResultType.SUCCESS;
                    }
                }
            }
        }
        return ActionResultType.PASS;
    }

 

 

In addition, I know that there are four ActionResultTypes, when exactly should each of those types be returned? I notice that I get a slightly different behavior based on which type I return.

Return something other than PASS? Pass means "I didn't do anything."

Check the other values and return the obviously correct one.

I do return something other than PASS. PASS is the default return if none of the cases are met.

Ah, I see. Perfect. Thanks that did it.
