tehAon’s Zipline – Ride a Cable Between Buildings

- **Powered ziplines.** Wire a generator, battery bank, solar bank or switch into any mast or wall anchor
with the wire tool, in either click order, and every cable in that line is powered. On a powered cable,
holding forward runs a motor: 12 m/s toward the end you face, uphill or down, no stamina, hands on the
T-handle. Past motor speed on a steep drop, gravity carries you as before. The ride prompt says
`[powered]`, and the wire tool's label on a mast says whether it has power.
- Each mast and anchor draws 5 W and passes the rest down the line (the fence post it is built on draws the
same), so a weak source can leave the far end dead. A switch turns a whole line on and off.
- Wiring power into a mast in the middle of a line re-hangs the cables above it so the line runs from the
powered mast — nothing is cut. A line that already has a power source refuses a second one.
- Linking a cable onto a powered mast never cuts its power: the link is turned round, or refused, the
same way a link that would cut another cable already was.
- Power still never flows OUT of a zipline, and the spool still only links masts.
- New settings `MotorSpeed` (12) and `MotorAccel` (8).
- **Longer spans: the spool reaches 512 blocks** (was 64). A cable whose far mast is out of view is still
drawn (by the near mast) and still ridable, and is redrawn properly when the far mast loads. The server
now keeps each mast's parent position current so clients can see a cable's far end at any distance,
which also repairs worlds saved with older versions on load.
- **Carry the line.** Click a mast, travel to the next one however far (up to the spool's reach), and click
it: when the first mast is out of view the server links the two from its own power graph, which holds every
mast loaded or not, with the same rules as linking up close (turned round rather than cutting a cable,
refused when both masts already hang from something, eight cables per mast, never a loop, claims respected).
- **Link from where …

- **Ziplines in the world.** A new world strings a few ziplines between rooftops in some of its towns, for
you to come across: an Old Zipline Mast on a tall building, a cable down to a lower roof nearby. Every line
is checked before it is built by riding it offline, with the ride's own curve, body and gravity against the
POIs' real blocks and the ground: let go at the top and you roll to the bottom mast without touching
anything. Nothing new to place or craft; the mod is still needed on the server and every client.
- **Forest only, by default.** Lines are a bonus for the early game: by the time you leave the forest you can
build your own. `WorldLineBiomes` says where they may go and, optionally, how many per biome:
`pine_forest` (default), `pine_forest:20,burnt_forest:5`, or `all`. Both buildings must be in an allowed biome.
- Rare on purpose: every forest town (four or more POIs together) with room for a line gets one or two — two
where two fit — one line per building, no two crossing, at most 40 on the map. 30–128 m long, dropping no steeper than 35°. On a
6 km test map: 6 forest lines in the 4 forest towns with room for one (18 lines in 9 of 16 towns with every biome allowed at a 50% town chance). Settings: `WorldLines` (on), `WorldLineBiomes`, `WorldLineTownChance`,
`WorldLinesPerTown`, `WorldLinesMax`, `WorldLineMinLength`, `WorldLineMaxLength`, `WorldLineMaxSlope`,
`WorldLineMinRoof` — set them on the server before the world is made.
- The plan is made once per save, when the world first starts, and written to `zipline-worldlines.xml` in the
save folder; a mast is put up when its chunk is first made. Adding the mod to an existing save only builds
lines over ground nobody has been to yet.
- World masts can't be picked up (every town would be a free stack of masts); a wrench salvages them. They are
put back when a quest resets their POI (a reset clears the roof) or a chunk is regenerated, never after a
player breaks one.
- Traders' compounds, street tiles and P…

Cruise, boost, optional rider collision, and a server's settings that actually reach its riders.
- Cruise: on a powered cable, forward starts the motor and it keeps running when you let go, toward the end you were facing, until you brake, jump or arrive. MotorCruise turns it off.
- Boost: hold sprint with the motor running for 24 m/s, paid in stamina. BoostSpeed, BoostAccel, BoostStamina.
- Optional rider collision for servers: RiderCollision stop (stop behind whoever is ahead) or drop (knocked off). Default is still pass: riders ride through each other as before.
- The rules of the ride are now the server's: speeds, motor, boost, cruise, rider collision and sag are sent to every player who joins, and again after zl set or zl reload. Before, each player rode by their own file.
- zipline.xml ships in the mod folder with every setting, its default and what it does; your changes go in zipline.local.xml beside it.
- Fast riding checks for blocks every half metre, so boost cannot carry you through a wall.
- Optional speed readout for tuning: zlc readout on shows how fast you ride and whether it is the motor, boost, hauling or gravity. Off by default.
- New zlc console command: the same questions as zl, asked of your own game (on a server zl answers for the server, which never rides).
- A MotorSpeed above MaxSpeed now counts (the motor was held to gravity's top speed).
- Boost works with Sprint Lock set to toggle or autorun: a tap turns it on, another turns it off.
- Masts and wall anchors lose the wheel the cable never ran over: the cable now ends in a thimble and shackle on a swivelling lug, as a real zipline is tied off. Same attach point; saves unaffected.
- Update the server and every client together: an older Zipline on either side will not connect to 0.5.0.

- No more kick from a server that doesn't run Zipline. 0.5.0 asked the server for its ride settings as soon as you spawned, and a server without the mod can't read that request, so joining one with Zipline installed threw you off. Zipline now checks the server has it before asking for anything, and on a server that doesn't it just does nothing.

- Works on game 3.3. Game 3.3 changed how the game hands a held item to the code that uses it. On 3.3 that made 0.5.1 throw an error every frame you held the wire tool, with a spool or with plain vanilla wire, so nothing could be wired at all while Zipline was installed. Zipline now reads those values in a way that works on every game version from 3.0.0 to 3.3.0, from one download.
- If a later game update moves them again, Zipline says so in the log and switches itself off instead of breaking the wire tool.
- Nothing else changed: cables, settings and saves are untouched. Server and clients can update in any order.
