Known Issues

  • The interface in general is not great, but is getting better.
  • Various ships are implemented but don't have real graphics, so they just show a little "rock" instead where the ship graphic would be. You can still see the ship icon and whatnot just fine.
  • Most ship shot types use the same graphics right now.
  • Only some of the sound effects are in, and only a couple of music tracks.
  • Balance needs a lot of attention, with your help.
  • There is a tutorial, but it's new, and we're not sure how comprehensive you'll find it.
  • The lobby is still very small, and a work in progress.
  • Multiplayer may have some issues at the moment, although we need more testers on that.

Version 0.700

(Not yet released -- we're still working on it!)

  • IMPORTANT NOTE: contrary to our normal practice (even in alpha/beta), we've broken all old savegames with this version. Just too much AI-state data moving from "one set for the whole world" in the Core implementation to "for each faction that needs it" in the moddable External side, etc.
    • We obviously won't do this kind of breaking change after release, per our normal approach with AIWC.
  • Added some options to the Start Game lobby to allow waves with homogenous or varied composition, and to select the amount of advanced warning you get for a wave.
  • Fix a bug where Maze, D18Swirl and D18DensityMap weren't displaying the correct map type in the Save/Load screens
  • Right-clicking a build menu item or build queue item now acts like alt+left-click:reduces the amount of that unit queued.
    • Thanks to Kahuna for suggesting.
  • Fixed a longstanding bug that generally prevented the showing of health bars for guardians/etc in many circumstances.
  • First pass at descriptions for all in-game units. Cursory, possibly incorrect and needs flavour, but it's something at least.
  • Completely redid how the intra-squad formations were set up, so that now it's both more efficient, and more importantly more correct.
    • There no longer seem to be any cases where ships in a squad are spawning on top of another ship within the same squad, and if they do it will now throw a warning error.
    • Additionally, if a formation is too small for the number of ships that the game says should be in it, then it will now throw errors rather than just stacking the ships on top of one another.
  • Fixed a bug where the Warden Fleet could attack one of "your" planets if it is an AI planet you conquered after the Wardens "set sail", so to speak.

  • Additional visual enhancements (iterative improvements: things are better but not perfect)
    • The number of ships in a squad should now more accurately reflect a squad's health
    • When a ship takes lethal damage it now changes to a "Dying" graphical state instead of using particle effects.
    • Ships start burning the same visual frame that a shot hits the target, not the frame afterwards. It makes things feel snappier.
    • When a squad is reinforced, the reinforcing ships use a cool "Warping In" effect
    • When you first move your view to a planet, damaged squads should now have the correct number of ships
    • Lightning and Flak AOE effects are in use by the appropriate units
    • When a structure is under construction, use an "Under Construction" visual effect for it. The effect is either Green for "normal construction" or Yellow for "blocked construction". Construction is blocked if you have paused construction or are out of metal
  • The game now displays, in fiery animated letters, "YOU LOSE," then on another line, more slowly, "HUMANITY HAS PERISHED," when you lose the game.
  • Massively improved the visuals of the ship on the main menu. Come on, it's the first thing people see. ;)
  • Major update to the starfield backgrounds!
    • Remember those awesome ones that we were showing off during the kickstarter and for a while after that? Well, Badger did as well. ;) Those have returned.
    • We took them out, previously, because we had a variety of complaints from players who were saying that they were too bright and were distracting from the main combat. But that sentiment isn't unanimous by any stretch, and these backgrounds look COOL.
    • Our plan is to make it so that players can exclude the sort of backgrounds they don't like (ones that are too bland, or ones that are too bright) for in-game purposes.
    • Meanwhile, we've updated which ones can show up on the main menu, and in the galaxy map, and these should be ones that are pleasing to everyone in terms of being more varied and more thematically appropriate for those parts of the game.
  • You can now select the style of planet backgrounds you want: All of them (default), just the "fancy bright" (old style) ones, or just the "dim" (more recent) ones.
    • This is a per-client setting, so you can have different BG visuals for a planet per player if players choose different values from those settings.
    • Note that these settings only take effect when creating a new game or loading a savegame or joining a multiplayer game, so changing these in the settings menu while already playing won't change anything.
  • The "Burning And Dying" effect has actually be transformed into a full, GPU-only explosion effect where vertices are offset over time based on the direction of their normal, and a "burn ramp" effect makes emissive textures come in white, then very bright, then fading a bit more.
    • Translation: EXPLOSIONS WITHOUT PARTICLE EFFECTS. :D
    • Basically what this does is make the battles way more epic, but without having the expensive (in CPU AND GPU time) particle engine get involved.
    • This is actually barely any more expensive on your GPU or CPU than having the ships just disappear at death, and it's actually slightly more efficient than our first "burning and dying" effect, which was itself very efficient. So... yeah. Go team explosion. :)
  • Bloom, ah... finds a way.
    • Right. So bloom, which we've added and removed and tweaked a million times, is now back... but in a very weak and subtle way.
    • This style of bloom finally avoids the pitfalls we were seeing before, but it is what lets the emissive ramp of the new "burning and dying explosions" actually look like explosions where there is none.
    • The result is super effective, and we can actually make a variety of different death "explosions" of differing intensities, colors, and whatever else we want, based on the type of ship, building, who owns the ship... anything we want.
    • It's SO effective, in fact, that we might ditch our literal particles altogether, in favor of performance. This also tends to look a lot better, since it is by definition exactly the size of the ship or structure that is exploding, unlike the true particle effects.
  • In fact, we've now taken the "burning and dying" to the next level after all.
    • The ships and structures no longer throw off particles on death at all -- not shuriken particles like they used to, anyway.
    • Instead, it now has burning and dying effects that can be defined per ship type, rather than globally. There are different colors (slightly) for the last ship in a squad compared to all the others, and structures have a different pattern of disintegration.

Major Camera Improvements

  • Added a major new type of camera, which is now the default, and which has two modes: Basic Strategic and No-Pan Strategic.
    • The Basic Strategic one works... well, basically like you would expect it to, based on AI War Classic.
      • It fixes a lot of the fiddliness of the Angled and Top-Down cameras previously available in this game.
      • Because this is from a third party, however, unfortunately this has to remain closed-source, unlike the other cameras.
    • This camera also now introduces two new hotkeys: R and F, for tilting itself up and down.
    • Since the camera is able to zoom in MUCH further than before, and has great tilt and pan and rotation controls, the free-look mode is not implemented on it.
      • Using this camera you can actually zoom down inside a squad of bombers and pan through them easily, etc. You can actually see the ships up close in general! Yet it's not fiddly to get from that extreme zoom to the other extreme of zoom, seeing the entire planet.
    • In general the zoom is very graduated so that you have more degrees of zoom as you get further in, and additionally the edge scrolling, WASD-scrolling, and middle-mouse-to-pan scrolling all work more smoothly at each zoom level.
    • On the no-pan variant, the middle mouse button being held down instead takes you into a "tilt and rotate" mode.
    • The rotation in this camera is based around a "turntable" concept for where you are pointing your cursor (or where the focal point of the camera is, anyway). This is different from the "tripod" style rotation that was there before in the other cameras (and is still there in them -- you are free to use any of our cameras, still).
    • Finally the camera feels like a friend rather than a foe! ;)
  • Previously when you were in free-look mode and then came out of it, the rotation of your camera would be all messed up in the Angled and Top Down camera modes. Fixed.
  • Fixed some general jerikiness that happened on occasion in our camera movement in particular; it was present in our old camera code as well, but more easily noticeable in our free-look camera code and our new camera that is part of this release. The jerkiness was also affecting some other random things, like fade-ins and a few timers. It was not affecting ship movement, however.
    • So what was up? Well, we were using Time.deltaTime, which normally is fine... except in a game where there are garbage collection calls every so often, you'll get very harsh spikes that are noticeable in animated stuff, particularly camera movement. We're talking about the difference of 100ms or so, but it's still substantial enough to feel really off.
    • Fortunately Unity provides a built-in Time.smoothDeltaTime, which automatically smooths those out so that we don't even have to do any of the hard work ourselves. We've now switched everything over to using that.
    • Incidentally, it wasn't just the garbage collector that was throwing this for a loop -- since our underlying simulation runs at a lower framerate than the visual part of the simulation, some frames are definitely longer than others. That was leading to micro-stutters that were irritating but possibly below the level where you'd be able to pinpoint what was bugging you.
    • All fixed now, at any rate, near as we can tell!
  • The game now supports separate speed adjustment multipliers for "fast mode" for cameras panning, rotating, and zooming on the galaxy map and in the planet view. There was no purpose in having a fast mode for tilt, because that's a pretty fast and definitely cosmetic thing anyhow.

Larger Planet Gravity Wells!

  • The radius of each planet's "play area" has been doubled, moving AIW2 much closer to AIWC in spatial scale.
  • The xml data relating to distances has been reworked:
    • Rather than one constant for the radius of a grav well and a variety of multipliers based on that (seconds for ship to cross grav well, what % of the radius a short-range-weapon has, etc), there's now constants for:
      • Grav well radius.
      • Base unit radius.
        • These used to be constants for every unit; these are now happily all multipliers, making broad adjustment much easier as well as avoiding raw distance units existing in multiple xml folders.
      • Base shield radius.
      • Base weapon range.
      • Base AOE radius.
      • Base ship speed.
      • Base shot speed.

AI Difficulty Levels

  • AI Difficulty is now selectable in the lobby, ranging from diff 1 (AI strength budget-to-fight-you is about 20% of normal) to diff 5 (the default, normal budget) to diff 10 (AI strength budget-to-fight-you is about 1000% of normal).
    • Lower difficulty is somewhat "dumber" with its units, specifically it waits longer before considering retreating during an attack (i.e. how long your turrets get to shooting-gallery a wave that's not strong enough to threaten you) and it waits longer before sending waiting threat off to join the Hunter Fleet.
    • Higher difficulty waits less time for both of those things.
    • The old core-dll definition of difficulty has been removed, replaced by a definition in the external (moddable) code.
  • AIP is now tracked per-AI-faction, and has been moved almost entirely from Core to External (moddable). The remaining core fields that store AIP numbers (how much AIP on death, etc) only have effect because External uses them.
  • The AI Warden Fleet and Hunter Fleet now have their own difficulty settings.
    • The Warden Fleet's population cap is now based on that setting and the base income of the Sentinels faction.
    • The Warden Fleet now starts with a certain difficulty-based % of its population cap already filled, so it can oppose your attacks earlier (it still starts at the AI homeworld so you have a little breathing room).
    • The Hunter Fleet, on difficulty 6 or above, now starts with some strength. That strength is based on the base income of the Sentinels faction and the Hunter Fleet's difficulty setting.
