Impact – HTML5 Game Engine
- kodablah 8y agoIs it maintained? Only commit in over 3 years appears to be the readme and license.
- tcfunk 8y agoBase on their blog post, it looks like its lack of maintenance was the driver for the decision to go open source http://impactjs.com/blog/2018/05/impact-is-now-free-open-source http://impactjs.com/blog/2018/05/impact-is-now-free-open-sou...
- phn 8y agoAre there any active projects using this? It seems to me this was a big thing back in the day but not really relevant anymore.
- rushsteve1 8y agoIf I remember right CrossCode[1] is using it. Fun game but another case of near endless beta. [1]: http://www.cross-code.com/en/home http://www.cross-code.com/en/home
- 542458 8y agoIt's worth noting that crosscode's version of the engine is HEAVILY rewritten - it's not really a good representation of the base engine's capabilities.
- NapoleonSolo 8y agoThe CrossCode devs seem very active on their Discord and company blog. (Last blog posted 3 days ago) [1] If you want a peek behind the scenes of the gamedev check out their YouTube channel [2] to see an archive of their weekly programming stream from Twitch.

- ibdf 8y ago"Publish your Games into the AppStore with almost native performance". This had me laughing. Maybe too honest.
- Kiro 8y agoEjecta is actually pretty cool. It maps all the ImpactJS render calls to native OpenGL draws plus other stuff like that. > JavaScript code is executed directly by a JavaScript VM (JavaScriptCore), the HTML5 Canvas 2D and WebGL API is implemented in native code with OpenGL, Audio is implemented with OpenAL. Several other APIs (touch, accelerometer, localStorage, gamepad) behave like those in a real browser. http://impactjs.com/ejecta http://impactjs.com/ejecta
- Xuper 8y agoSo I solves a lot of pain points and the only problem you are left with is dealing with JavaScript? It's quite neat, but why not simply use a better language and an engine? E.g. Unity3d, MonoGame, Godot?
- yuchi 8y agoWeb distribution is way easier this way, obviously.
- always_good 8y agoIf you're targeting the web, then you're compiling to Javascript anyways, so the indirection + engine complexity isn't always worth it. Unity tends to pay off as you take on more platform targets and/or implementation complexity (like graphics), for example. It's kinda like using https://github.com/schteppe/p2.js https://github.com/schteppe/p2.js for physics instead of Box2D: if p2 gets the job done, then you get the advantage of working with a much simpler code base than Box2D which is just about impenetrable as an emscripten port.
- bluedino 8y agoThe demo game for Impact was Biolab disaster http://playbiolab.com/ http://playbiolab.com/ It's got retro feel, and shows the power of the engine for making scrolling games. Really neat project and I was surprised that it's 8 years old already.
- outworlder 8y agoPerhaps the most well-known game is Z-Type. http://zty.pe/ http://zty.pe/
- RobertRoberts 8y agoThat was nice a for a minutes. It's funny how the web, free software allow for so many games these days that are free that I think we can take it for granted. When I was a kid, getting _any_ game at all was amazing. Kids these days are overwhelmed with free stuff, it's likely the reason an engine like this has a hard time making money.
- hutzlibu 8y agoYes, but the usual "free games" kids get today, they pay with their attention, and or data, and/or later with real money to make progress in the game. All the games of my childhood I bought(or pirated) .. were 100% about the game. vut when I see my niece and nephiew playing and accpeting lots of advertisement all the time in their game, like it's normal, I get a bit sad. So of course, I push other content to them... but I would say the ordinary kid today, gets a lot worse input today, the I did. And I would like to see much more real free, open source games out there. But apparently very hard to make money with it..
- optymizer 8y agoHow does it compare with PhaserJS?
- k__ 8y agoPhaser is still maintained. Impact got its last update years ago.
- iteriteratedone 8y agoIm curious, whats the best game built in phaser? Lets compare engines after we compa re games built byvthe engines. Then we can ask was the engine the limitation or just the designers approach.
- yesimahuman 8y agoI built a game with Impact a number of years ago and it worked very well. It also comes with this really simple but powerful tile editor https://github.com/phoboslab/Impact/blob/master/weltmeister.html https://github.com/phoboslab/Impact/blob/master/weltmeister..... Regardless, it was a great way to learn 2d game development and got me to actually pay for a software library!
- always_good 8y agoSame. And its collision map was a great resource when I was looking for the next upgrade to my own naive collision system. https://github.com/phoboslab/Impact/blob/f461c2f4054dac37dea351d8fe3440eae6a2f47e/lib/impact/collision-map.js https://github.com/phoboslab/Impact/blob/f461c2f4054dac37dea...
- city41 8y agoI was a big fan of Impact back in the day. It's a great general purpose 2d engine, but it's especially great for platformers. I collected all my Impact plugins here: https://github.com/city41/ImpactPlugins https://github.com/city41/ImpactPlugins
- 542458 8y agoThere used to be a great impact plugin site, pointofimpact I think it was called. Unfortunately, it's all gone now, along with most of the plugins on it...
- rudedogg 8y agoHere's a page on the level editor: http://impactjs.com/documentation/weltmeister http://impactjs.com/documentation/weltmeister
- drdrey 8y agoHow does it compare to PhaserJS?
- always_good 8y agoSmaller in scope thus simpler. Unmaintained. Far easier to borrow pieces from as needed. For example I implemented networking on top of my Impact game with relative ease (networked games are never easy) while layering it on top of my Phaser gamer would've taken longer and with more uncertainty because Phaser is far more opinionated and larger in scope.
- diminish 8y agoIMHO - Phaser3 is promising to be the winner html5 framework last few years. But I didn't check if anything new came up in past 1 year.
- tluyben2 8y agoI created some games for client in this; I liked it quite a bit. Interesting to see if someone picks it up. We encountered only small issues with it which did not really hamper development at the time.
- benrbray 8y agoNeat! By clicking on some links I found the blog of who looks like primary developer of Impact, Dominic Szablewski. http://phoboslab.org/log http://phoboslab.org/log It's nice to see a blog with articles from ~10 years ago that aren't broken! I really like his WebGL rendering of WipEout maps: http://phoboslab.org/wipeout/ http://phoboslab.org/wipeout/ http://phoboslab.org/log/2015/04/reverse-engineering-wipeout-psx http://phoboslab.org/log/2015/04/reverse-engineering-wipeout...
- mrspeaker 8y agoWow, this is fantastic! I feel like Impact never got the attention it deserved: at the time of release it was miles above the rest of the 2D pack, and the author was brave/crazy enough to charge money for it (which obviously hindered greater uptake, compared to Phaser - but it showed he was serious about it as a real product). The editor it came with was fantastic - and there still isn't a lot of movement in this area for other game libraries (I think Phaser has a third-party paid effort that is shaping up) Then he released Ejecta as open source, which was a real game game-changer for me: 60FPS canvas games running on my old iPHone 3G - it was FANTASTIC! I would have given up on tinkering with HTML5 games along time ago if it wasn't for Dominic, so, if you happen to read this, thank you for all your effort!
- VectorLock 8y agoI've never heard of Ejecta, thanks for the heads up. I wonder if an Android analog exists?
- stcredzero 8y agoMy procedurally generated huge-universe MMO uses Go on the back end but ImpactJS on the front end. < https://www.emergencevector.com https://www.emergencevector.com > I was meaning to port the game to PixiJS to be able to open source the front end, but now I don't have to! (Even better, now that I know Ejecta is also open source, I can have OpenGL and iOS distribution!)
- phoboslab 8y agoIt only worked because the Impact community had people like you. Thank you so much <3
- ezekg 8y agoI absolutely loved playing Xibalba, and was actually thinking about it a few days ago. One of the few HTML shooters that was performant on my mobile device -- actually played through the whole game on mobile. Awesome to see the engine open sourced.
- ryanpcmcquen 8y agoI hope someone gets Weltmeister running client side now (without PHP). Then you could hack on Impact using a Chromebook!
- 542458 8y agoThere are a few node drop-in replacement for the PHP components. The one I've used in the past is: https://github.com/drhayes/impact-dev-server https://github.com/drhayes/impact-dev-server
- ryanpcmcquen 8y agoI have seen those, most of them seem abandoned.
- always_good 8y agoThough so is Impact (well, unmaintained) and its plugin ecosystem (the website died and the plugins it hosted are lost), so it's more or less something you have to be comfortable with if you choose to use Impact in 2018. Excited to see it open source now, of course. Great opportunity for a community to slowly redevelop and rebuild what once was. I used Impact as recently as two years ago despite these issues and was able to make a networked game. The code is easy to work with and understand. And I used one of the Node wrappers to get the editor working without PHP.
- Kiro 8y agoWhy was the title changed? The interesting part here is that it has been open sourced and made free. Now it sounds like it's a new engine or active project. http://impactjs.com/blog/2018/05/impact-is-now-free-open-source http://impactjs.com/blog/2018/05/impact-is-now-free-open-sou...
- clessg 8y agoI agree — I don't think I would have given this post any attention otherwise. Impact is old news. Its open sourcing is not.
- optimuspaul 8y agoI've been seeing a lot of title changes lately that seem far too editorial to me.
- trumped 8y agoHN has been like this for years... not that I like it, but it's not new.
- falkenb0t 8y agowas there a title change? the link goes directly to the github page.
- Kiro 8y agoIt used to say "HTML5 Game Engine Impact is now free and open source".
- matt4077 8y agoAnything that might provoke interest in an article is considered "clickbait" by the HN community and neutered. A famous HN headline of 1963 was "JFK returns to Washington after visit to Dallas"
- tomcam 8y ago
- platelminto 8y agoDoes anyone know how this compares to Construct 2 & 3? I've only used Construct for simple 2D HTML5 game development, and haven't really heard of any other HTML5 game engines.
- Andrex 8y agoConstruct is a fully visual game editor, no code is required. Impact is an engine, so you have to write your own JS to do anything.
- n-gauge 8y agoI used this years ago - however ended up with construct 2. I've also contributed to the open source scratch 2 apk (runs in a browser) using webRTC for the cloud vars. It's the only scratch emulator with lists support too. https://github.com/htmlgames/htmlgames.github.io/tree/master/htmlgames/differences/UAT/itchy https://github.com/htmlgames/htmlgames.github.io/tree/master...
- xorcist 8y agoI imagine Impact is from a time when javascript wasn't as performant and far from as portable as today. Is it still relevant given the canvas and sound improvements in a modern browser? What would be the major use cases for something like Impact versus starting from scratch?
- always_good 8y agoWell, do you think it's worthwhile to implement your own collision map system, vector math, tile editor, etc. every time you start a new game? It sure is tempting, but not necessarily healthy to the odds that you will ship a game. Though it's also not obvious how much a game engine will help you (like if you'll run into issues with your specific mechanics) until you credentialize in it, so it's always a bit of a crap shoot because games are so open-ended. For example, I once migrated away from PhaserJS because I couldn't figure out how to add networking and server-side simulation without having more of the physics code in my git diffs.
- NapoleonSolo 8y agoAnother notable site that used Impact (for the client) is the multiplayer universe http://Manyland.com http://Manyland.com
- iteriteratedone 8y agoWe dont need another game engine ... we need a good game. No one has created a good html 5 game. This is because engineers make good engines but its the creative artist spirit that makes works of art. Any game designer will use unity over any html5 engine. Why not?
