| /** |
| * Block proxy for all real block implementations. |
| * |
| * All of our blocks are implemented as "sub-blocks" of this block, i.e. they |
| * are instances of this block with differing metadata. This way we only need a |
| * single block ID to represent 15 blocks. |
| * |
| * This means this block contains barely any logic, it only forwards calls to |
| * the underlying sub block, based on the metadata. The only actual logic done |
| * in here is: |
| * - block rotation, if the block has a rotatable tile entity. In that case all |
| * sides are also translated into local coordinate space for the sub block |
| * (i.e. "up" will always be up relative to the block itself. So if it's |
| * rotated up may actually be west). |
| * - Component network logic for adding / removing blocks from the component |
| * network when they are placed / removed. |
