I made a pass on the new website

by Esteban Lorenzano

Hi, I made a pass on the new website. I improved a bit documentation: - added âimmediate linksâ :P - added pharodocs reference link We still need to do a lot of work, but we are making improvements. Ah, I also promoted Laurentâs video to first page :) Esteban

Clement hilaire told me that he has friends developing in C++ simple educational game and this is a hell to deploy on differetn platforms While with Pharo this IS simple.

Re: [Pharo-dev] developing games in Pharo

by Esteban Lorenzano

in my discharge, I have to say that the only reason why the pharovm is not released for iOS is because Iâve been really busy to properly configure the jenkins slave. But you should be able to produce an iPharo vm (is stack, no support for JIT yet) as easy as compiling any other vm. And I know Jean-Baptiste is in his way to revive the Android platform. In general about gaming, I think nothing prevent us to have something like pygame working right now (technically we have all the elements), just that as a community, we usually are more focused in other directions. But Ronnie is finishing his SDL2 work and soon we will have a version of OSWindow that we can actually use (that will lead to another vm-plugin cleanup. but thatâs another story). SDL2 even has bindings for audio, so we could have audio access without the ALSA/Pulse pain we are having this days. With OpenGL/OpenCL support (which is also being made by Ronnie, he) we could even have very fast graphics support without going out the image (well, just to call those libraries). In other order of things (some-kind related) a couple of months ago Eliot told me that he can be in his way to give us an âexecuteOnProcessâ primitive, that would solve most of our parallelisation problems (and Eliot will be probably hating me at this moment, I know he dislike announcements before they are at least startedâ¦ Iâm sorry). So wellâ¦ I think the answer should be: 1) it is possible, 2) but things are poor documented and we need to improve there 3) as being a pioneer in the gaming for mobile area (with pharo), you will need some work. And of course community (and me in particular) is willing to help as much as we can. 4) â¦ and of course since thatâs a non frequent area for us as a community, they will be probably things to overcomeâ¦ but again, they will all be solvable and we are willing to help. cheers, Esteban On 11 May 2014, at 09:39, kilon alios <kilon.alios(a)gmail.com> wrote: > "What does "not support" mean?

Usually a Pharo application have at runtime a memory footprint of less than 30Mb. And now even small embedded devices have at least 256Mb of RAM. Cpu usage is also OK. Now note that on ARM devices (typically, Android, iOS and RISC OS), the VM is 2-10x slower. Therefore you may need to profile and optimize a bit your application before deploying on ARM devices. We have a profiler in Pharo that you can easily use to do that. For the download part, you can shrink your Pharo executable by removing unused important packages in the image and the source file. > > 5) Sorry for the redundancy if these questions have been asked before > (which I am sure they have). > Yeah well this mailing list is Pharo-dev it is usually a bit more oriented towards the development of Pharo itself.

What framework are you using for your graphics ? Because if plan to use Athens (our vector graphics framework), graphics will for sure go faster, but you should know that it relies on Cairo, and Cairo is not stable on every OS (for example it is not stable at all on iOS, so no iPad/iPhone and bye bye cross platform application). Else the graphics are bit based and these may be a bit slow if you're doing heavy graphics computation. Btw, you may want to discuss with J.F. Rick, he has already implemented and deployed educational computer game (desktop app) with Pharo and touch screens. You may also want to try to ask question to the guy that deployed DrGeo (I think he's named Hilaire Fernandez), it's an app to teach geometry to kids AFAIK, it has quite some graphics, and it's deployed on Apple store/Google play. I guess he's the guy to ask on how to deploy on iPhone/Android. > > > Ralph Boland >

Re: [Pharo-dev] developing games in Pharo

by kilon alios

I am no Pharo expert but will try to answer with what I know 1) Pharo download is 16 mb compressed and 58 mb uncompressed. 2) Pharo is a standalone and as such it does not need installation. Everything you need is in a single folder contained in a single zip with a single download. I dont think you can get any easier than that. So its a single task. 3) There are people who run Pharo on iOS like DrGeo. But Pharo does not support those platforms and most likely you will experience few problems with it. So its some extra work but its doable. They do represent a larger market and a very important one I agree. 4) Again I dont know the issues on those platforms but bare in mid, Pharo is a dynamic language and dynamic language are definetly not a first choice for those platforms for game because they are slower than official supported languages. Those are in iOS ObjectiveC and on Android Java. All that assuming your game has some demanding graphics. For simple graphics with not much animation and such you should be ok. Personally I think its not a good idea, because Pharo does not support those platforms well. I think that in that scenario there is a better alternative , that of Javascript + Pharo. Its possible to use JS as front end and Pharo as backend. If you dont want to code in Js there is Amber. Web apps are quite performant so you will be able to do some really impressive graphics with this recipe. You will be using also technologies that are well documented and well tested. Also there are like a ton of game libraries for JS out there. Which will lift the amount of work you will need to do for your game.
