MIMESIS - BetterJump

🛟 Need help or found a bug? Get support at support.doodesch.de/betterjump.

Makes jumping in Mimesis actually useful - the stock jump is near-useless for getting around, so BetterJump retunes it (stronger configurable jump plus a brief forced-airborne window) to clear gaps and obstacles reliably.

Features

• Retunes your local player's jump so it is actually useful for map traversal (the default jump is near-useless).
• Configurable upward jump velocity (default 4.8 units/second) - raise it for higher, stronger jumps.
• Configurable "force unground" window after takeoff that keeps you airborne briefly so the game does not instantly re-detect the ground, improving jump responsiveness (default 0.08s).
• Applies to each modded player's own avatar and only triggers from the ground. Jump rules follow the lobby host.
• Single Enabled toggle to switch the mod on/off without uninstalling, plus an optional DebugLogs switch for troubleshooting.
• Uses your normal jump key - no input rebinding.

Requirements

BetterJump reads private jump and ground state through MimicAPI and will not function without it. Installing through a mod manager pulls in MimicAPI (NeoMimicry-MimicAPI-0.3.0) and MelonLoader automatically.

For Nexus, install MimicAPI 0.4.2 separately. Keep one Mods/MimicAPI.dll; the mod archive does not include it. Thunderstore resolves its existing MimicAPI dependency through the mod manager.

Installation

• Recommended: install with a Thunderstore mod manager (r2modman or Gale). It installs MelonLoader and MimicAPI for you - just click Install.
• Manual:
  1. Install MelonLoader 0.7.3+ into MIMESIS.
  2. Place both BetterJump.dll and MimicAPI.dll into MIMESIS/Mods/.
  3. Launch the game once to generate the configuration file at UserData/MelonPreferences.cfg.

Configuration

Stored in UserData/MelonPreferences.cfg under the BetterJump category.

Each Steam lobby uses a snapshot of the host's Enabled, JumpVelocity, ForceUngroundTime and AirGravityScale settings. Clients use that snapshot without overwriting their saved configuration. DebugLogs stays local. If the host does not have BetterJump, clients use vanilla jump behavior. Change the host configuration before creating the next lobby.

Usage

There is no keybind - just use your normal in-game jump input. BetterJump hooks the game's jump and ground-check logic, so jumping simply feels stronger and more responsive.

• Raise JumpVelocity for higher jumps; adjust ForceUngroundTime if jumps feel cut short.
• Set jump rules in the host configuration before creating the lobby.
• Effects apply only to your own avatar.

Changelog

All notable changes to BetterJump are documented in this file. The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[1.5.7] - 2026-10-11

• Jump rules use the host's settings for each Steam lobby; debug logging stays local and saved client configuration is preserved.
• Clients use vanilla jumping if the host does not have BetterJump. Jump state resets when effective host settings change.

[1.5.6] - 2026-10-11

• Built against MIMESIS 0.3.2. Jump settings are unchanged.

[1.5.4] - 2026-09-04

Changed

• The mod is built against MIMESIS 0.3.1 and tested in a running game on that build. Jump behaviour does not change.

[1.5.3] - 2026-06-22

Fixed

• The mod's Harmony patches were applied twice (MelonLoader auto-applies them, and the mod also called PatchAll() itself), so every jump patch ran twice. The redundant call was removed; patches now apply exactly once.

[1.5.2] - 2026-06-17

Fixed

• The Nexus file description now uses BBCode so the changelog renders cleanly there (it previously showed raw Markdown). No gameplay changes compared to 1.5.1.

[1.5.1] - 2026-06-17

Changed

• Started maintaining a full changelog that is now published on GitHub, Thunderstore and Nexus. No gameplay changes compared to 1.5.0.

[1.5.0] - 2026-06-17

Fixed

• Jumping works again after the Mimesis 0.3.0 update: a jump actually changes your height once more. The game's new ground handling was cancelling the upward impulse the instant you left the ground.
• You can no longer re-trigger a jump in mid-air to climb upwards. A jump is only re-armed after you have actually landed.

Added

• New AirGravityScale preference for tunable airtime. Reduced gravity during the rise gives a floaty, higher arc that blends back to normal gravity near the apex (so there is no hovering at the top), while the descent keeps normal gravity for crisp landings.

Changed

• Tuned jump defaults: JumpVelocity 4.8, AirGravityScale 0.7.

[1.4.0] - 2026-06-15

Fixed

• Compatibility with the Mimesis 0.3.0 game update (updated the MimicAPI reference for the new game build).

Changed

• Refreshed the README and project documentation.

[1.3.0] - 2025-11-15

Added

• MimicAPI integration. Jump internals are now accessed through MimicAPI's reflection helpers for better compatibility across game updates.
• Optional debug-logging preference for troubleshooting jump behaviour.

[1.2.0] - 2025-11-15

Fixed

• Release packaging and Thunderstore upload fixes; the post-build step now only runs on Windows.

[1.1.0] - 2025-11-15

Added

• Automated build-and-release pipeline and Thunderstore packaging.

[1.0.0] - 2025-11-15

Added

• Initial release. Makes jumping in Mimesis actually useful so you can navigate the maps.
