If you want to get a chance to access the latest and greatest version of Momentum Mod, including the map selector, you can now sign up for Playtest from our Steam page!

In the meantime, you can still check out the older 0.8.7 build of the game, with the following caveats:

1. This does not work with our website.
2. Runs will not submit or show up on our leaderboards.
3. Map selection doesn't work (and is even hidden in this build).
4. Multiplayer (lobbies, SRCDS, etc) does not work.
5. If these limitations are too much, consider helping out to get a key for the most up-to-date build, or patiently wait for 1.0.0.

To install, download the respective .zip for your platform. Extract somewhere. Read the README.txt to learn how to boot the game.

You can find maps, help, and more on our Discord server.

Hopefully this holds people over until 1.0.0!

0.6.2

You Got a Purdy Map

• Saul Rennison's Dynamic RTT Shadows - More accurate shadows cast by world lights
• Brian Charles' Parallax-Corrected Cubemaps - More accurate reflections for cubemaps on world geometry

(Both of these can be found in live examples in the triggertests map!)

Small Features Added

• Disabled inputs - The keypress HUD element now shows disabled keys set by triggers
• Invalid run start - A sound now plays if the run cannot be started (will be expanded upon)

• mom_speedometer_colorize 2 - New colorization method suggested by Acta
• mom_stage_tele - Teleport to the start of a specific stage number (1 = start)
• showRuler - Shows a menu to measure distance in-game (in units)
• sv_gravity - Allow players to change gravity in-game
• sv_tickrate - In-game changes force a reload, allowing replays of different tickrate to be played

RIP Tim, You Shall Be Missed

• .tim files are completely removed, in favor of reading replay files

(This means all replays prior to this update will be ignored due to a new format)

Edit 15/08/2016: Updated zip filename with the correct versioning

0.4.0 had some prominent bugs that were found merely hours after release, so 0.4.7 is set to fix them.

0.4.7

• Changelog Introduced
  • The version update panel now includes a changelog for the newer version.
• Spectator UI Updated
  • Now includes toggled mouse control upon pressing your +duck bind
  • Added a red X that stops the replay and respawns the player (similar to MapFinished)
• Added StartupVids.txt to override Valve's startup vid
• Bugfixes
  • Fixed scroll detection
    • Scrolls of all force are detected now, player should jump properly (sorry about that, scrollers!)
  • Replays
    • Fixed crash with replays not unloading properly
    • Fixed potential crash with replays ending
    • Fixed velocity setting to a value that was too high (due to teleports)
    • Fixed potential "roaming" spec mode if replay was finished
  • Ending player movement actually approaches 0 now (player will stop in end trigger)
  • Fixed width of settings panel labels
  • Mapfinished panel resets to page 0 properly

The development team has been hard at work on the biggest update yet: pre-alpha 0.4.0.

This update is split into four sections: replays, comparisons, accurate timer, and map finished UI screen.

• Replay System
  • Automatically records replays for every run
  • Small, lightweight file (28 bytes / tick)
  • Truncates the recording to the first two seconds before the run started to show prestrafe only
  • Supports all stats that were displayed during the real run
  • Allows playback of ghosts with options for 15 different display models and customizable colors (see mom_replay_* commands for more details)
• Comparisons Panel
  • Compare your current run against your PB
  • Compare against any run stats; all, some or none
• Precise Timer
  • Times accurate to 6 decimal places (however, we currently only display 3 decimal places)
  • The only timer for surf or bhop that is more accurate than the interval per tick
  • Read about how it works here
• Map Finished Screen
  • Mouse controls for watching the replay of the run you just finished
  • Pages for stats in every zone, not just overall
  • Shows both XY and XYZ velocity (controlled by mom_speedometer_hvel currently)
• Other changes
  • Added Source Shader Editor
  • Added both XY and XYZ velocities to run stats
  • Player's velocity is now slowed down when they finish a map to allow them to see the map finished screen
  • Crosshair is off by default
  • +left and +right are now bindable from Options->Keyboard
  • JUMP indicator in key press display no longer flashes when the player uses the scroll wheel to jump
  • Credits can now go faster if +attack is pressed
  • DIsabled demo interpolation, which fixes demo stuttering bug, but makes demos lag. Demos will work properly if you turn off client interpolation (cl_interp 0) but this breaks other things
  • point_servercommand entities are disabled by default
  • sv_gravity is development-only (sorry)
  • Player FOV setting now works properly through fov_desired
  • Changed mom_generate_zon_file to mom_zone_generate

0.3.0-prealpha is a large update to the look and feel of Momentum. Release notes:

• Completely overhauled UI
  • Velocity is can now be colorized based on acceleration (togglable, on by default)
  • Added strafe sync numerical display and visual bar (also colorized)
  • Added keypress display with jump and strafe counter
  • Added dialog showing statistics after you complete a run
  • Added support to save run statistics per-stage as well as overall, which will be expanded upon in future updates
  • Added time splits for stages
• Changed main menu
  • Font has changed
  • Custom settings panel for all of the new momentum-specific settings
  • Changed colors of all panels in the menu to align more with Momentum's color scheme and aesthetic.
• Overhauled start zones
  • Start zones on bhop/kz maps limit your speed so you are encouraged to get a good edge when prestrafing out of the zone
  • Start zones on surf maps do not limit your speed unless you bhop inside the start zone.

A version check is now done on game startup to let the player know if a newer version is avalable

EDIT: FIXED FOLDER HIERARCHY

Remember that the current version of the mod is pre-alpha which means that it works, but it lacks a lot of features.

Description of the added feature:

• Scroll game mode added, with CS:S stamina system.
• maps with the kz_ prefix will automatically use the scroll gamemode.

Initial release on GitHub. From now on, every merged pull request that adds a considerable feature will have its own release.

Remember that the current version of the mod is pre-alpha which means that it works, but it lacks a lot of features.

Description of the added feature:

• Blocks doors and buttons from moving so speed is not lost but keeps teleporting the player if they stand on the platform for too long.
