About this mod Author’s original text

Rival Isles

Rival Isles is a small PvP-style test arena island for How to Fish and the reference/test map for HTF Map Loader.

Its main purpose is to demonstrate that custom islands can be distributed as completely separate packages and discovered automatically by HTF Map Loader.

Requirements

  • HTF Map Loader 0.2.8
  • BepInEx 5 / Mono
  • How to Fish

Use Install with Mod Manager. Required dependencies are declared by this package.

Map configuration

Map ID: rival_isles

Display name: Rival Isles

Bundle: rival_isles

Unity scene: HTFE_Island9

Author: Rompedev

Placement: automatic

Radar color: #FF4FA3

The Unity scene is still named HTFE_Island9 internally because that is the scene embedded in the current AssetBundle. This does not affect the public package/map name.

The map declares:

PlayerSpawnPoint

BoatSpawnPoint

as its runtime spawn markers.

Wildlife is disabled for this test arena.

HTF Map Loader 0.2.8 discovers it automatically.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.
