Frame Block
Frame blocks allow for more than one block to be moved by a single pusher/puller. This is done by attaching a frame block to the coloured side of a pusher/puller, then attaching any non-entity block to the other available transparent sides.
A side that's transparent indicates that it's in an 'open' state that lets other blocks stick and move with it.
A 'closed' side will cause any block attached to that side of the frame to not be moved by the pusher/puller. This allows frame blocks to drag certain blocks and slide past others. However, attaching a closed side to the coloured side of a pusher/puller will still allow the frame to be moved.
Also note that putting the open side of one frame block to the closed side of another will result in the closed side sticking to the open side, causing them to move together unless there is an obstruction.
The 'open/closed' settings are preserved when the block is broken, allowing you to place it somewhere else without needing to calibrate each side again.
Right click on a side with the wrench to toggle an open or closed state.
A Wrench Hammer lets you open/close 5x5 frame blocks at once.
