Ziplines: build two posts, run a rope between them and ride it, hanging from your axe.

What is in it

The Zipline Post is in the hammer menu (Misc). Build one, build another (a line can be kilometres long), press E on the first and then on the other, and a rope runs between them.
A line only runs downhill: press E on the higher post to ride. You hook your axe over the rope and hang from its handle with both hands, feet dangling. Without an axe (or with the setting off) you hang from a wooden triangle instead.
You are lifted to the rope and slide along it, faster downhill and faster on longer lines, the view widening and the wind rising, and are eased down at the far end. Press jump to let go. Shift+E on a post takes its line down.
A line has to be rideable: it must fall enough, your feet must clear the ground all the way and nothing may stand in the way; if not, it says why.
The lines are saved with the world (each post keeps its partner's place, so the far end need not be loaded), and others see you glide.

Everyone in the world needs it installed (the post is a building piece: a game without the mod deletes it when its area loads). Restart after installing.

Known clashes

Ziplines by Einherjer: both work side by side, each with its own posts and ropes.

👥 Multiplayer

Who needs it: Everyone, and the host above all: a game without the mod deletes the pieces when their area loads. Restart after installing or updating them.

A line is saved on both posts, so it comes back with the world. Running or taking down a line needs ward permission at both posts; anyone can ride.

The host decides: line length and slope, speeds, and whether you need an axe. While you play on their world their values replace yours (your file isn't changed); a host without the mod leaves everyone their own.

⚙️ Settings

In BepInEx/config/com.quad.ziplines.cfg, made the first time the game runs with the mod. r2modman and Thunderstore Mod Manager edit it under Config editor.

Lines

Setting	Default	What it does
`MaxLength`	`12000`	The longest a zipline can be (metres). A line remembers where its other end is, so the far post does not have to be loaded: the world around you loads as you ride. In multiplayer the server's value applies.
`MinSlope`	`0.005`	How much a line must fall to be ridden, as a part of its length (0.005 is 5 m in every 1000). A line only runs downhill, from its higher post to its lower. In multiplayer the server's value applies.

Riding

Setting	Default	What it does
`LongLinesFaster`	`true`	The longer the line, the faster you go (up to eight times), so a line of kilometres takes minutes, not an hour. You slow down for the last stretch either way. In multiplayer the server's value applies.
`TopSpeed`	`24`	How fast you go downhill at the most (metres per second). In multiplayer the server's value applies.
`MinSpeed`	`5`	How fast you go on the flat or uphill at the least (metres per second). In multiplayer the server's value applies.
`HangBelowRope`	`2.5`	How far below the rope your feet hang (metres): your arms reach up to the handle, so this is about your height plus a little.
`NeedAnAxe`	`true`	You hook an axe over the rope and hang from its handle, so you need one with you to ride. Off, you hang from a wooden triangle instead. In multiplayer the server's value applies.
`SpeedPercent`	`50`	How fast the whole ride is, as a percent of the standard speed (50 is half as fast, 200 twice). In multiplayer the server's value applies.
`WindVolume`	`0.12`	How loud the wind is at full speed (0 to 1).
`WideView`	`true`	The view widens as you speed up, for the feel of it.
`WindSound`	`true`	The sound of the wind, rising with your speed.

🤖 Made with AI

Made with the help of Claude (Anthropic), with Claude Code: designed, written and checked together, and tried in the game.

📜 Recent changes

0.2.3 A clearer page: what it does, who needs it in multiplayer, how it gets on with other mods, and where to report a bug. The game itself is unchanged.
0.2.2 Its test command for Claude Tools (zip ...) follows the game's cheat rule: spawning, removing and riding test lines and tp work only in single player, for the host or with devcommands; status, posts and hover still work for everyone.
0.2.1 A new id, com.quad.ziplines (it was com.dhack.ziplines): your settings move over by themselves the first time it starts, and the old settings file is kept as a backup. Restart the game after this update. If an old copy is still installed beside it, this one stands down and says which file to delete, so the two never both run. The DLL now says it was made with AI, as Thunderstore asks. The log says so when Einherjer's Ziplines, a different mod with the same name, is installed too.
