    Picking colors to look good with eachother is hard. Is there any tool or something that can help me out?

    Posted: 31 May 2019 04:20 AM PDT

    Finished prototyping the basics/main stuff for my game. Now it's time for art. I'm learning pixel art.

    I am struggling a lot in picking the right colors to look good with eachother. Also having trouble doing highlights and shadows (actually, for shadows I just do a black with a 127 alpha)

    Here's some of my work:

    I just... don't know what colors to pick... Most of those colors were from palettes that software has built-in.

    Any tips?

    Developing 60 Uniquely Playable Characters: Our Process

    Posted: 31 May 2019 08:13 AM PDT

    So firstly, we're the guys at Troglobytes and we've got a new game out on Steam Early Access titled HyperParasite. It's a twin-stick brawler set in a dystopian eighties that pays homage to the cinema of the era with its unique body-snatching mechanic. With over 60 enemies/characters in the game that you can collect and control, each host has their own set of attacks and specials.

    Getting the look of each of our characters has been a major part of the process throughout, as we essentially give each of them a personality. The basic punk character with his chain swinging attack and spinning special was a character that we introduced early on in the game. Laying out the visual aesthetic took some time, especially when keeping it in tone with the rest of the game. Not only that, we needed to keep his stats and buffers levelled with the rest of the characters too, especially when considering that he's a character who's introduced early on. This has been an ongoing process, something that we've fully utilised our Early Access status for, allowing the players to help us find our balance.

    Other characters such as our Geisha, who is introduced later in the second act of the game is another example of finding that equilibrium. With her ranged attack she shoots fans, whilst using a whirlwind special that clears most of the screen. The process from concept design to how she finally handles in the game has been a long one, but we're happy with the result. This can also be said of our bosses, such as 'Double Trouble', which involves a set of armoured police trucks spraying bullets everywhere which way.

    We hope this brief look at our character design and implementation has been informative? As we continue building upon it we're always looking for new ideas on how we can adapt and improve, along with ideas for possible new characters. Thanks guys.

    Where do I need to be to find people to work with?

    Posted: 31 May 2019 11:49 AM PDT

    I want to make a first person horror game but doing it myself is kinda difficult, not the game itself but the assets needed for it, is there a place I can look for anyone that wants to do the same and just work on a project together?

    I can't start a indie group since I don't have any money to spend

    Does anyone use Procreate and an iPad Pro for asset creation?

    Posted: 31 May 2019 11:16 AM PDT

    I've been creating pixel art with Pixaki and really enjoy it. I'm thinking I might want to branch out from pixel art and try something like Procreate - just wondering if it's suitable for the task of creating and exporting assets for a game, and if anyone's using it for that purpose.

    Thanks!

    How were old style 3D RPGs written?

    Posted: 31 May 2019 07:05 AM PDT

    I'm interested in how old "3D" RPGs were written. Games like Eye of the Beholder, Lands of Lore 1 and Dungeon Master.

    Does anyone know any current sources that discuss how those games worked? Specifically rendering.

    I've tried google, but I just can't find the search terms I need.

    Did they use ray casting? Or a bank of pre drawn images that the just rendered to the surface?

    I want to anchor my player movement to my mouse on a key press/release

    Posted: 31 May 2019 12:25 PM PDT

    I have this "FaceMouse" script that makes my player face wherever the mouse is pointing. it has a little drag feature to make it feel less snappy. As i was originally adding it in it was broken in which my player wouldn't onlythe cursor but the controls would actually hook to the mouses position. So, if my cursor was in the top right and i held down "W" for instance, the player would approach go towards the mouse instead of towards the top of the screen. It made for a cool little "circling" affect when holding down "A" or "D" which would make the character orbit the mouse. I thought this was annoying at the time, so I fixed it, but now I think it would be a cool feature. I want to hold down a key like CTRL and be able to "circle" my crosshair/downed target.

    ​

    FaceMouse Script: http://prntscr.com/nw0ggm

    PlayerController Script: http://prntscr.com/nw1l0i

    (These are the only two scripts I have in my project at the moment)

    ​

    I'm also having some skipping problems with Cinemachine if anyone can help with that as well.

    Game Dev Resources Telegram Bot!

    Posted: 31 May 2019 08:35 AM PDT

    Hi to everyone!

    I have been working for a few weeks on a Telegram bot that collets a lot of game development resources, from free assets to interesting web sites.

    It has become a great collection of around 400 different web sites, YouTube channels, etc. It has 4 different sections: assets, tools, tutorials and interesting sites. The tutorials and sites are both english and spanish websites.

    You can chat with the bot using this link: https://t.me/gamedevresourcesbot.

    If you have any suggestions, you want to include anything of your own work in the bot, you know any interesting assets site, whatever... just tell me in this thread, via MDs here or on Twitter (www.twitter.com/TEAteam_), or via the bot, using the /suggestions command.

    And also, if you want to support us, you can spread the word about the bot in the way you want. Maybe a retweet to this tweet would help too: https://twitter.com/TEAteam_/status/1134477983270522880

    Thank you'll very much! Have a great day.

    ​

    The little game dev bot greets you!

    Fixed Timestep Rotation Stutter at Specific Timesteps (with interpolation)

    Posted: 31 May 2019 12:14 PM PDT

    I am currently in the process of implementing a fixed timestep game loop following the legendary "Fix Your Timestep" article. I have managed to get everything setup and working...or so I thought, until I started to change my timestep value. I seem to be running into an issue where a stutter is produced during rotation at specific timesteps (linear movement (forwards, backwards, left, right) is always smooth when rotation is not changed). Below are the different timesteps and encountered results when running with vsync enabled on a 144hz panel:

    • 144 updates per second - smooth rotation, minor stutter every once in awhile but barely noticeable (possibly in my head)
    • 128 updates per second - rotation stutter highly noticeable
    • 30 updates per second - smooth rotation, no stutter noticed

    When the above timesteps are used with vsync disabled they all appear to have smooth rotation. The takeaway (at least my takeaway) is that the more render cycles that happen between update steps, the smoother the rotation.

    I have been going back and forth as to why this could be (this is the first time I have attempted to implement something like this so it's possible I have missed something someone else might instantly notice) and the thing that throws me is the fact that the interpolation appears to be working as expected for lower update rates (as seen from the 30 updates per second test (if I attempt the 30 updates per second test with interpolation disabled everything stutters horribly as you would expect until interpolation is enabled again)), but then appears to not be working when the render cycles more closely match the number of update cycles.

    ​

    I have included my code below which I believe to be relative to the question (can add additional pieces upon request if I have missed something). Is there anything that points out as being horribly wrong??? Any advice greatly appreciated!

    int main() { glm::vec2 screen_size = glm::vec2(1280, 720); InputState input; Window window(&screen_size, &input); if (window.getInitFailed()) { std::cout << window.getInitMessage() << std::endl; return -1;

    What have you found helps with user retention?

    Posted: 31 May 2019 05:43 AM PDT

    Hello everyone, I'm just starting off in the gamedev world, and so far I have two games out on Google Play. My first game didn't work out so well, but I thought my second was better buts it's retention numbers aren't too great either. So I figured I'd ask you experts what you thought. Either general lessons and experiments, or if you want to look at my apps for specifics that'd be great (just look through my post history). Thanks in advance.
