OpenCity(6)

✨ OpenCity(6) ✨ — the manual page for opencity, bestie 💖

okay so this is the manual for OpenCity, which lives in section 6 of the manual (the games one, obviously 🎮). It's The 3D city simulator game and it's giving main character energy fr fr. Sit down, grab a strawberry 🍓, and let's get into it.

🌸 NAME 🌸

opencity — a 3D city simulator game 👑

✨ SYNOPSIS ✨

opencity [-fs | --full-screen] [-glv | --gl-version] [-dd | --data-dir
newDataPath] [-cd | --conf-dir newConfigPath] [-na | --no-audio]
[--generator-height-map heightMapPicture | (--generator-seed seed
[--generator-map MAP-TYPE] [--generator-water WATER-TYPE]
[--generator-map-shape MAP-SHAPE-TYPE] [--generator-tree-density
TREE-DENSITY-TYPE])]

like, that's the whole vibe of how you launch it 🚀

💅 DESCRIPTION 💅

This manual page documents opencity command. That's it. That's the description. Iconic brevity, no notes 🎀

---

🦋 OPTIONS 🦋

• -fs | --fullscreen — turns on fullscreen mode, so the city fills your whole screen 🌈
• -glv | --gl-version — shows you the info about which OpenGL implementation is currently available on your machine, and then it dips, it quits, bye 👋
• -dd | --data-dir newDataPath — points OpenCity at a new path for its data. Example, because examples slay:

--data-dir /home/foo/bar/share/opencity/

• -cd | --conf-dir newConfigPath — points OpenCity at a new path for its configuration. Another example, you're welcome:

--conf-dir /home/foo/bar/etc/opencity/

• -na | --no-audio — disables the audio system entirely. silent mode, no cap 🤫
• --generator-height-map heightMapPicture — loads a gray-level picture as a height map (PNG, okay, PNG specifically 🖼️). Here's the tea: the water level is gray level 128, and each map level is one gray level. Which is exactly why the whole picture looks like it's sitting in a medium gray — because there's only a minor difference between the pixels. You can draw the height-map yourself or generate it from any map sources. The interesting data for this work is the DEM satellite data 🛰️. And lowkey the map generator in OpenCity will crop the picture if it's too big, so don't stress about sizing.
• --generator-seed seed — the seed is the random integer seed used by the map generator 🎲
• --generator-map MAP-TYPE — MAP-TYPE: 0=plain (default), 1=hill, 2=mountain ⛰️
• --generator-water WATER-TYPE — WATER-TYPE: 0=dry, 1=lake (default), 2=coast 🌊
• --generator-map-shape MAP-SHAPE-TYPE — MAP-SHAPE-TYPE: 0=none (default), 1=island, 2=volcano, 3=crater 🌋
• --generator-tree-density TREE-DENSITY-TYPE — TREE-DENSITY-TYPE: 0=sparse (default), 1=normal, 2=dense 🌳
