This is a block that loads chunks. There is a limit on the number of chunks each non-op player can load in SMP, and each chunk loader can load an adjustable area.
Right clicking opens this GUI. If you are op (or in singleplayer) or the owner of the chunkloader, you can change the size of the loaded area without breaking and replacing it (which would make you the owner).
The green button expands the area loaded by this chunkloader by one chunk, and the red button shrinks it by one chunk.
As you can see, there is a limit on the number of chunks that each player may force to be loaded. In singleplayer, or if the owner of the chunkloader is an op, there is no limit.
Pressing F9 shows loaded chunks, as with the Teleport Tether, however the format of this display is quite different.
It displays four things.
First, you can see a blue or orange box around all chunk loader blocks, even through walls. This is useful if you bury your chunkloaders and forget where they are, or if somebody tries to cause lag on SMP.
Blue boxes indicate chunkloaders you own, while orange boxes indicate chunkloaders owned by someone else. Orange boxes are only visible in singleplayer, to ops, or if they have been enabled in the server config (chunkloader.hideOtherPlayersLoadersInF9=false).
For the rest of this section, a “visible chunk” means a chunk that is being kept loaded by a chunk loader you can see with a blue or orange box; if you can’t tell a chunk loader is there, you can’t tell which chunks it is keeping loaded.
Second, a translucent blue border will be drawn around the chunk you are standing in, if it is visible. This border cannot be seen through walls, and helps to see whether your machines are all in the same chunk.
Third, a green line will be drawn in each corner of each visible chunk.
Fourth, a translucent red square will be drawn above your head height, in each visible chunk. It will be drawn once for each chunk loader ? that is, if two or more visible chunk loaders are keeping the same chunk loaded (and thus the chunk is counting multiple times towards your limit) the red square will appear darker.
This *is* visible through walls and ceilings, so that you can see it indoors.
If you set chunkloader.useFuel=true in immibis.cfg, anchors will require fuel to run. Anchors without fuel will be treated as if they don’t exist ? so they won’t appear in F9 or contribute to your quota. (This also means you can set them to a larger area than you’re allowed, and it won’t be reset until you put fuel in)
If you set chunkloader.allowFuelPiping=true in immibis.cfg, then automation mods (such as Buildcraft pipes, RedPower 2 tubes and ComputerCraft turtles) will be allowed to insert fuel into anchors. If it is set to false (which is the default), they will be blocked (using ISidedInventory).
The available fuels and value of each fuel is configurable in immibis.cfg. This is mainly intended for server admins.
The amount of fuel used is scaled by the number of chunks, so a 3×3 loader will use 9 times as much fuel as a 1×1 loader.
