Cobalt v121 Alpha Change Log

June 27th, 2013, Cobalt, Updates & Patches

For windows users wanting to update from v120 to v121, you will need to download a new switcheroo.exe and place it in your Cobalt folder, or reinstall directly using the installer. Download the Mac installer here.

To everyone with opengl32.dll problems: Download and install: Openal

To everyone with random engine crashes, make sure you have removed any old openal32.dll in your cobalt folder, and reinstall: Openal

Long time, no see! We have mentioned over the last couple of posts that we are working on the Adventure component of the game. This update will not contain the adventure we built so far since we want to make a good first impression, but it will contain all the improvements, features, tiles, actors and what have you that we have been adding and tweaking for it. So while we have put several months of development into this update, this update does not yet contain the main part of those efforts. The main purpose of this update is:

  • Stability and fixing crashes and optimizations.
  • First real test of mac support!
  • Improvements to editors and lots of new content for mappers including the tile lighting systems!
  • Marking the return of more regular updates.

Since this alpha will be the first with Mac / OS X support, please report any problems you encounter specifically on that platform to us!

Change Log


  • Adjusted melee attack forces. If damage is done, less counter force is excerted on yourself.
  • The first item in each slot are rendered on actors when not in hand.
  • Added ninja animations
  • Adjusted a bunch of maps.
  • Talking to actors! (related to adventure)
  • Peaceful actions (related to adventure)
  • Relations (related to adventure)
  • Compare item stats
  • Compare upgrade stats
  • If you time the roll to start just when the bullet hits, you will do a reflect instead of a deflect. Reflects are better in the way that they return the bullet to where it came from, and you dont get moved or affected or slowed by the hit.
  • Slightly less aimspeed bonus in rolling
  • Reworked and tweaked plasma
  • Enhanced railgun sounds and effects
  • Tweaked railgun bullet speeds closer to the higher ones.
  • Improved and streamlined ai with regards to destination logic
  • Tile color brush in editor. (press . and ,)
  • Certain tiles (among them the light bulbs in editor) now give off tile-corner affecting light.
  • Ctrl click a tile to flood fill.
  • More placement options to respect already placed tiles, and also to respect the physical layer (press 1 in editor)
  • Possible to set grid and angle snap to raycast mode which find the closest wall and sticks to that.
  • Glass jar tiles
  • New actor: Brain, spawned from metalfaces if the game mode allows it, can fly around with a small jetpack, carry small items
  • Items now have a size parameter. Brains can only use items such as matter prototype and slugger cobra, while shrooms and birds and such small actors can use items up to grenade launchers and such but not the largest ones such as rail vanquishers and plasma cannon.
  • Beam gun adapted to work with bullet time and slightly modified
  • Heat/Cold mechanic changed. It used to work by making your heat restoration become delays on each hit. Now you have a “peak heat” and an “average heat”. Peak heat is what kills you and is what is affected by attacks and fires. Peak heat and average heat move towards each other, and average heat in turn moves towards the environment temperature (map weather). This means that being heated if not fatal will still raise your average temperature for a while, making the peak heat restore slower.
  • Shield is now split into 3 different shield belts with lots of upgrades each.
  • New Save&Compile, will pre-generate the map previews and save them inside the file. This is also done automatically if save© to menu is used.
  • Maps have their previews pre-generated and saved into the file.
  • Metalfaces can use the emergency action: Eject their brain upon death! Controllable from the game mode settings (default off for all except adventure) and actor spawn modifiers.
  • Checkpoints now work slightly differently. If you have a respawn cell (now called emergency cell), your brain actor will be teleported back to the checkpoint and the metalface will be rebuilt. If you do not have that, you can still walk back and rebuilt yourself for a cost. If you have an ally you can have the ally “rescue” you by purchasing the rescue service at the checkpoint which will teleport and rebuilt your friend. If your brain actor dies, you are dead, except if you have an ally that can carry your brain to a checkpoint and revive it for a cost.
  • Improved swimming
  • Space theme can now specify a different gravity
  • Tweaked slugger weapon fire rate and damage to be between the old and the new.
  • If outside of weapon range in the air, and using aim (duck/sneak), you will tweak your aim slightly up and down depending on your movement.
  • Added more radio stations, fixed so that radio channels don’t reset, added the radio jingles the current ones.
  • Improved dance logic and added automatic starting of dance if game detects a bpm to your actions while listening to music from a radio.
  • New Item: Sabre Egg.
  • Game now has a rather slight falling damage. You can still fall 10 screens without dying, but you will get hurt. Falling 2 screens is fairly harmless.
  • Stunning small enemies now only occurs while rolling onto them
  • Predator can now bite.
  • Buy/Sell Shops (adventure related)
  • Buy/Sell information (adventure related)
  • Bots pick colors too.
  • Ninja has a strong melee attack.
  • Space jellyfish now drop healing sparks when they die.
  • Power station tiles and power system improved. Now there are two special power stations which each require a special plug. (CTP remains unchanged). Lights, shops, locks, batteries and wire-system sockets can be powered using either a battery, power station or simply by not picking anything. Things are powered by default! Power can also be changed with triggers.
  • Doors have an on used action which is called when they are opened.
  • All things lockable have an on unlocked action which is called when they are unlocked.
  • Radiation! Currently caused by radioactive green blobs and radioactive fluids.
  • New Icon!


  • Fixed crash on safest gate…
  • Solved a resolution bug that made the game crash at certain low resolutions
  • Corrected map names
  • Fixed shader related assignment bug
  • Removed actor collisions on plug
  • Cleaned up ai code
  • optimized phys line render
  • Fixed two way teleporting for actors and objects
  • Fixed teleport shader not showing correctly while rolling
  • Throw object and loot spawn optimizations
  • Sound driver related crashes fixed by going back to openAl Creative on Windows.
  • Fixed self destruct not destroying yourself.
  • Fixed airbomb ai.
  • Fixed slanting girder error.
  • Fixed jetshoes bouncing on gas plants and teleporter problem.
  • Fixed space theme coordnate bug
  • Fixed entrance shader malaligned to actual event.
  • Simplified and fixed some predator leg bugs
  • Fixed some annoying stunning behaviours when shot from behind.

    One problem I am having is (what appears to be happening once I shoot the 1-directional bot) this crash:

  16. FatLlamaFeet :

    I seem to be having the same problems that I’ve had for a long time now, so maybe Cobalt just doesn’t run well on some computers.

  17. David :

    For some reason my game lags if I shoot at brains, especially with a plasma weapon.

  29. Grant :

    The game doesn’t seem to run on this version of OSx, although Minecraft does. Does this game require a more up-to-date version than 10.6.8?

  30. slypuphound :

    when are you guys adding multiplayer oohhh im supper exited for the update!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  31. VanillaC0coa :

    Awesome! New update!

    Time to play more Survival Hou-…

    Aaaaand the game crashed to desktop…
    no error log…

    But when the game worked the highlight was being shot out of my suit and flying as a brain XD

  32. VanillaC0coa :

    Ok I jut realized it crashes when i get killed for some reason… maybe it has to to with the brain’s textures or if it’s just my computer.

    I’m using windows 7 which shouldn’t be a problem…

  33. VanillaC0coa :

    Damn… it also happens in death match…
    i dont know what’s wrong -_-

  34. Person :

    So far working well. There is a bug when you die and try to get reconstructed it freezes.

  35. Melvin :

    Thank you so much for the Mac version! :D I bought the alpha beginning of last year (I think) and have only been able to play through lag on Parallels :P I’m downloading now and am really looking forward to playing!

    Thanks again,
    - Melvin

  36. Darklight11 :

    finally i can play on my mac!!!

  38. Bob!"# :

    this update is big…..

  39. Bob!"# :

    This update is big

  40. FabiotheTurtle :

    Oh, awesome guys!

    Let me tell you all that you’re doing an amazing job with this, you really are. Cobalt has come very far from its origins, and from where I started off in v103 Alpha. That being said, it’s still in Alpha, which means there’s way more to come, even though it’s already so awesome! You’re all doing some great work.

    I adore the new lighting system, it’s even better than I imagined. Some areas of the map are just so much more visually exciting and impressive, it’s really great. But, the resultant contrast (or perhaps the tweaking involved) has made some areas particularly dark, it seems, and it doesn’t really fit the theme. I’m talking areas in Survival House, and Reluctant Runner. But, let me leave on a high note and say that high heat emits a glow? Outstanding! And the offhand weapons are a very nice touch, helps to know what you’ll switch to, when.

    Temperature! An interesting concept, to be sure. I was surprised, and it’s pretty cool how the edges of the screen change in the cold (and the heat too? I haven’t checked), and how Actors slows down. However – simply having a level cold enough to snow (which is oddly a running feature in my maps, it seems) makes you very cold, relatively quickly. I used to have the temperature setting all the way to cold, just as a precaution to get the mood and atmosphere right, but you get very cold and die not long after. I thought maybe turning it down (or up, heh) would ease off this effect, but as far as I can tell, you still get as cold, as quickly, you just don’t die from it anytime soon. In my opinion, I think it needs a bit of a nerf, or a more direct relation in regards to environment temperature (cold water still makes sense), or an option to disable it map creation. It’s just a little bit annoying.

    The new shields are interesting, and look very cool. It’s nice to see all the upgrades and such and their effects on gameplay. Speaking of which, I bought the Hard Shield and was trying to upgrade it, but it wouldn’t let me after the first upgrade in a given category… It made the same sound as if I didn’t have enough volts, which I most certainly did, and then some. I doubt this is an intended feature, but if it is, may I suggest it notifies the player that they’re only allowed one every few minutes or so? It’ll let you dink around with all the other options, though.

    And, unfortunately, I’m still getting regular crashes… I noticed that all my Challenge Map progress had been erased, which isn’t necessarily a bad thing, but I get the feeling it shouldn’t have happened. So I set out to do them, with not much trouble. I started out with the Matter maps, and got -43.15 or something seconds to spare on Elevator Dive, when it crashed. I figured maybe the game wasn’t designed to handle such abuse, but it seemed to have save the high score, and now crashes in the upper levels of Reluctant Runner, after the first burner. So, I moved on to the ice levels. Once again, second level crash, but it stopped after the first time as I went on for a better score, and now it crashes near the rock outcrop with the two bots next to the lava on Avalanche.

    I also get crashes in Survival and Deathmatches… Sometimes it happens just about when a bullet (usually a matter charge) hits, so I’m guessing it has something to do with the calculations, sometimes it’s grenade or flashbang effects, sometimes it’s seemingly random. Frankly I don’t know if the .dmp holds more than one crash scenario, so sorry about that if it doesn’t.
    As mentioned, I always use the Xbox controller, I usually play without OpenGL, but sometimes switch because it occasionally reduces some crashes, I don’t play fullscreen (once again, occasionally to test crash properties) and I have a resolution of 1366×768.

    Last but not least, the radiation effects are certainly interesting. Not what I was expecting.

    Thank you! Keep up the good work.

    P.S. I also finally noticed that the error dialog suggests that I start emailing, so I will begin to do so, unless they’re largely interesting.

  41. Landon :

    Yay! I have been looking forward to an update for months! Please release adventure mode soon! Downloading the current update right now. :)

  42. MaL1x :

    i cant start cobalt .. error openAL32.dll not found =? please reinstall

  43. Tjackson20 :

    I have a mac OSX 10.6 leopard, and when I open cobalt, it says:

    Cobalt cannot be opened because of a problem.

    Check with the developer to make sure Cobalt works with this version of Mac OS X. You may need to reinstall the application. Be sure to install any available updates for the application and Mac OS X.

    I already checked software update. Should I be posting this here? If not, where?

  44. Sakke :

    I have trouble updating. When it reaches 100% file data and 99% total, it crashes and I have to start updating all over again, only to get the same result again. please help and advise if you can!

  45. RayereSs :

    Missing OpenAL32.dll. Redownloading installer doesn’t help

  46. Sakke :

    At this point installation stops and installer crashes, does someone know why?

  47. Sakke :

    Well… Now I succeeded, but lost all my highscores, Was this a part of changing the maps? My actor was not deleted

  48. Landon :

    I can’t get it downloaded even if I download the switcheroo thing. I tried to just delete it and redownload it, but it doesn’t work. Every time I try to update it, it gets stuck, and every time I try to just redowload it, it gets stuck too. Our internet is fast enough that it should only take a minute. But it doesn’t, it doesn’t work at all. I really love this game, so please fix/help. Thanks. :)

  49. Nicolas :

    Landon im having the same prob always when i try updating it says error and download i tried everything it still doesn’t work and im stuck at v.100 and it wont update

  50. XAngeled :

    Cant Run It!
    tried to reinstall but it says:”The programs can’t start because OpenAL32.dll is missing from you computer try reinstalling the program to fix the problem.”
    i tried to reinstall but still that doesnt work :\

  51. admin :

    Nicolas: reinstall in a fresh location from the installer!

  52. admin :

    Xangeled: download

  53. admin :

    Sakke: check in you documents folder, there might be a folder called statistics, that folder has now moved into /accounts/[youraccount]

  54. admin :

    Sakke: make sure you have enough space on HD and install into a fresh folder.

  55. admin :

    FabiotheTurtle: Thanks for the feedback. Yeah i might tweak the cold a little. Just a little bit of snow shouldnt make you cold. I have increased the “no effect” range to -10 to +30. Regular crashes are sort of expected after this long time with this many changes. I have spend an entire day now just fixing bugs, so next version should be much more stable.

    If you have error screenshots i am most interested in those. So far i have identified and fixed about 5 different unique crashes, perhaps you have some news ones?

  56. admin :

    Person: can you describe the map, how many players, what was happening? Is it a crash? of a proper “freeze” where the app is no longer responding?

  57. admin :

    Spartan: Please try and explain again what is happening, i’m having a hard time understanding what you mean.? Did you get an error screenshot?

    Look in you my documents/Cobalt folder. There should be files called “ErrorScreen-130701-16.jpg”
    send them all to

  58. admin :

    mmdanggg2: still no official plan for that unfortunately!

  59. admin :

    Nathaniel: Sound like your exe file has failed to update. Try installing the 121 from the installer in a new folder.

  60. admin :

    Mark: it “should” work on 10.6. If it does not, then thats bad. We are looking at a way to fix that.

  61. admin :

    Grant: Should work on 10.6. We are looking at ways to fix this.

  62. admin :

    Soup: Actor changing in death match is map controlled, so it is up to the map designer.

    Press F to flip the conveyour direction.

    Fixing all the crashes in v122! Upgrade bugs fixed too!

  63. Mac :

    Im trying to play it on my iMac 10.6.8 and it wont work. Is it not compatible? Thanks :)

  64. Abrock2000 :

    The slow motion does not work in some capture the plug and death match maps. I am not sure what causes this. Please advise.

  65. FabiotheTurtle :

    People with crashes!

    I noticed in the change log, it states something about a changed icon – at first, I didn’t see it, it was still the Hamster. My friend advised me to right click the icon/shorcut, whatever, and Open File Location. This didn’t actually change the shortcut icon, oddly (computer fault, probably not developer), but it did change the game icon. This reduced all of the regular crashes, and I can now play again quite normally! However, I’m getting similar reports from my friend, that there are occasional ingame engine crashes, which is relatively fine. Just Ctrl+r, and you’re sweet.

  66. admin :

    Tjackson: It is “supposed” to work, but as you say, it isnt currently. We are aware of this.

  67. admin :

    Spencer: try downloading the latest one and see if things work now

  68. Nathan :

    i cannot run it because it cannot run on my version of mac! my mac is running 10.6.8 help please!

  69. tomferriere2004 Player of Minecraft :

    I love this game continue as his Mojang
