0.8.2, Baby

Why, hello there. It’s been a little bit, hasn’t it? Well, we have quite the update for you! Well, not just you, but also our playtesters, who have been waiting very patiently for another update. There’s quite a bit, so let’s get right into it!

A Tip of the Hat to You

Momentum Mod will be featured in the Tip of the Hats 2019 Charity Marathon, taking place from October 11-13. We’re very excited to have some of the best surfers (and maybe even jumpers) show off the game, and all for a good cause! You can find more information on their website: https://tipofthehats.org. The surf and jump segments will take place on the last two days, but be sure to check out the entire event and help benefit Camp One Step!

I Surf In Your General Direction

In honor of the event, we will be adding 19 new surf maps, and keeping one classic:

  1. surf_cyberwave
  2. surf_be_gentle
  3. surf_facility
  4. surf_hob
  5. surf_timewarp
  6. surf_innokia
  7. surf_valpect
  8. surf_sippysip
  9. surf_mudkip
  10. surf_torque2
  11. surf_progress
  12. surf_delight
  13. surf_symbiosis
  14. surf_exile
  15. surf_drift
  16. surf_artifex
  17. surf_fortum
  18. surf_unreal_njv
  19. surf_interceptor
  20. surf_lt_omnific

These will be replacing the other surf maps for the time being, but we will add back the original maps after the event!

Rocket Jump Like Nobody’s Watching

Yes, you read that right. Thanks to the efforts of Larry and ILDPRUT, Momentum Mod now has an initial implementation of Rocket Jumping ready to be brutally nit-picked apart tested thoroughly by our playtesters.

It’s just a first implementation, so: there’s only one map (jump_summer), we’re still using HL2 assets for sounds, particles and models, and we currently only support the soldier loadout. It’s also prone to have many, many bugs, but should be good to go by 1.0.0. There will be more maps and features coming in future updates!

What’s Up, Doc?

Introducing our brand new documentation website: https://docs.momentum-mod.org

This has been something that I have personally wanted since learning about GitHub pages. The documentation site serves as a reference to Momentum-specific entities, console commands and vars, as well as several guides related to the game. Some of the guides already on the site will help you with things such as using the zoning tools and creating surf ramps. It’s a work-in-progress, and as such, some articles may be (and some definitely are) placeholders. But, the site is entirely open source, and we would love all the help we can get with documenting the game!

Rotten Apples

Just a note to our around 4 or so Mac playtesters (and potential future Mac players), we will be planning to drop MacOSX support by 1.0.0. As you may (or may not) know, MacOSX Catalina (v10.15+) drops support for 32 bit applications. Unfortunately, Momentum has to be 32 bit as we aren’t a licensed Source Engine game and therefore can’t compile a 64 bit engine ourselves. Valve also seems to not care about future OSX support for Source 1 mods. So, we have no choice but to drop support for the platform entirely. We will continue to offer OSX builds in the meantime, however, we cannot ensure that Apple will allow users (or developers) to stay on v10.14 or below in the future, nor would we encourage users to purposefully miss out on security updates to their device in order to play the game. Hence by 1.0.0, unless other circumstances arise, we will be launching the public release with only Windows and Linux officially supported.
