About this mod Author’s original text

BoplGooSwap

Four new abilities for Bopl Battle. They appear at the end of the ability menu, which scrolls to fit them.

Everyone in a match must have the same mod and version installed (Bopl Battle is deterministic, so a mismatch will desync the game).

Abilities

| Ability | What it does |

| --- | --- |

| Grapple Goo | Lob a slimeball with the Grenade's throw animation (hold, release to throw). The first platform it touches gets a puddle of goo in your colour. Anyone walking on it, including you, moves at 35% speed. The goo never dries up; it only goes away with its platform. It also drags down projectiles passing through it, and when a grenade or mine explodes near goo, slimeballs fly out and the goo sprays onto the surfaces around the blast. Same cooldown as the Grenade. |

| Swap Shot | An instant shot along your aim. You trade places with the first thing it hits: players, grenades, arrows, blades, rocks, ability orbs, anything with a physics body. Platforms stop it, water makes it skip off the surface, and it passes through black holes. Cooldown 9 s. |

| Mirror | A forcefield around you for 3 s. Anything that flies into it has its velocity reversed (grenades, arrows, rocks, mines, fireballs, airborne slimes), and beams reflect off it like they do off water. Your own beams and throws leave through it. Cooldown 12 s. |

| Wall | A tall wall rises out of the platform in front of you, cast like the Spike. It is a real platform: you can stand on it and walk around it, and it cannot be pushed. It stays until you place another wall, or until the platform under it is gone. Cooldown 8 s. |

Installation

Install with a mod manager (r2modman, Gale or the app), which also installs BepInEx for you.

Manual install: install BepInEx 5 into the game folder, then put BoplGooSwap.dll in BepInEx/plugins.

Notes

  • All values are fixed in the mod (there is no config) so every player runs identical numbers.
  • To play vanilla again, disable the mod in your mod manager.
  • Found a bug? The log at BepInEx/LogOutput.log lists what the mod did and is the most useful thing to include in a report.

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.

Dependencies

Install these first, or the mod will not work:
