I am planning to use Godot to build games and machine learn AI's, but the graphics rendering is slowing it down too much to do train an AI. Would it be possible to temporarily take away the graphics to speed it up?
You can use Godot headless build or server build. Godot server is the Godot engine without graphics and sound (but can crash if you try to load an image or audio file).
Godot headless has graphics and audio modules but is meant to be executed on a terminal.
I need to create a Mac app which shows 3D models and those should support the multi touch events. This will be run in a Mac computer and the touch screen will be a Mac OS X touch screen. I will be using Unity3d to create the 3D models in a scene. I want to know how I can integrate these Unity models/scenes to my Mac App.
One option is to embed Unity web player to my Mac app. But the issue is in the Web player it doesn't seem to recognize multi touch events like pinch zoom
So the other option is to integrate/embed the unity3d models to my app directly. But I've no clue how to do that. In the Unity build options I can build for Mac standalone. But it creates a .app file directly. So I don't think I can use that to integrate with my Mac app.
Any help on this is really appreciated
Thanks
why bother making a second app and integrating the unity app into the first.
Why not just make the whole thing in Unity ?
forgot to mention.. there are a couple of free Unity demo's that illustrate how to create or modify meshes procedurally (if you are trying to make anything more complex than basic primitive shapes)
What kind of 3D models are you trying to make? Unity3D can only make primitives and really isn't designed for 3D modeling. So if you are trying to make more than just boxes, spheres, etc. you will need another program. Blender is free and works well with Unity. There is a plug in here that will allow you to make 3D models in Unity. http://gamedraw.mixeddimensions.com/ I haven't tried it myself but they have a free version you could try before buying the full plugin to see if it will fit your needs. I agree with the previous reply that if you are going to use Unity you might as well make the whole app in Unity.
I have experience in developing in actionscript via Flash, FlashBuilder, and FlashDevelop.
Flash is the only tool with which I am familiar for creating the .swf graphic and animation assets to be accessed/used by the AS3 in FlashDevelop or elsewhere. I like to being able to use the free FlashDevelop and not rely on expensive Adobe products, but I don't know of a substitute for Flash.
Is there a free or opensource type tool for creating graphics and animations?
You can use the Eclipse IDE with the Flex SDK to develop swf file Flash applets.
Also, for really simple things there is Ming for PHP.
Apparently, swftools allow you to
make swfs out of pre-created assets including .wavs, .gifs, .jpgs, .pngs, etc.
get information from existing .swfs including strings, imgs, fonts, sounds, etc
insert other swfs into swfs
compile swfs
a few other things
Meanwhile, both Eclipse with the Flex SDK and Ming via PHP allows you to develop applications with Actionscript which compile to .swfs and which could be used to code the drawing of graphics and their animation.
Unfortunately, none of these seem to be anything like a replacement for the drawing/animation capabilities of the Flash IDE.
At present, I have to conclude that though the programming capabilities of Flash are easily handled by freeware tools such as FlashDevelop, Eclipse w/the Flex SDK, and possibly Ming w/PHP, there are no freeware tools that handle its drawing and animation capabilities.

I've worked for some time with Corona SDK and love how fast and easy I can create powerful apps using Lua. But it can only compile for iOS and Android, which feels like too little now.
My main interest is for it to be able to compile to Desktop AND Mobile. At least for the following:
Windows + Mac for desktop, as standalone applications.
iOS + Android for mobile.
I'd prefer it to lean more towards Lua type scripting instead of ActionScript, but please feel free to post anything that you have worked with and love.
I've found the following engines so far:
Marmalade Quick - After further looking into it, Marmalade Quick can only build for Mobile!
IwGame - Works on top of marmalade and says it can deploy to
desktop and mobile with Lua. Any info is greatly appreciated on this
sio2 - Says "SIO2 is an OpenGLES based cross-platform 2D and 3D
game engine for iOS, Android, MacOS and Windows" and "The engine also
allows you to port your game on the Mac Store and on Windows.", but
their forum and web title is "Game Engine for Mobile Devices". Can't
find any info on if it can deploy to desktop platforms, any info is
greatly appreciated again.
Loom Engine - Loom is similar to Haxe + OpenFL (attempts to attract Flash developers) in that it uses AS3-like of ECMAScript, but it doesn't build native code from it. However it uses Cocos2D for rendering so it should in theory be as fast as Cocos2D. -- Thanks to Bojan.
SDL - I've read in multiple places that SDL can deploy to nearly any platform or device and has a Lua binding. But i can't find how this works as it's not an engine. Any one who can explain how it works and if it's possible is once again, very much appreciated.
SFML - "Windows, Linux, Mac OS X and soon Android & iOS. " doesn't use Lua but can use other languages like Java and Python etc. Anyone have any information on this?
Torgue2D - "Torque 2D was developed with OS X, Windows, and iOS devices in mind and works equally well on all the platforms." uses TorgueScript and no Android =(
Sencha - Seems to compile to all platforms, uses Javascript too which I know. But even with V8 JS would this work well performance wise compared to other options?
GameMaker - own scripting language GML and I actually remember this one as a tool for non-programmers. Has it actually grown into a real engine, I mean for serious development?
Construct2 - Same question as gamemaker
Corona - Lua but mobile only (Android and iOS only as well)
Cocos2D - Seems like it has lots of options but not sure with the same language? Seems like you'd have to re-write your entire code. Any info if cocos2D can deploy to desktop + mobile with almost the same code would be greatly appreciated.
Angel2D - Says it can deploy to everything except Android and uses Lua, anyone ever used this one before?
libgdx --- I've only seen good things about this. Here is a benchmark test for libgdx and is where I saw it reaching 40k sprites at 60fps. http://www.sparkrift.com/2012/1/love2d-vs-allegro-vs-clanlib-vs-libgdx-vs-cocos2d-x-vs-monogame-vs-xna-vs-sfml . It seems libgdx barely goes over 30k actually. But still seems amazing. This is on the same level as Qt for me, almost perfect, except I'm not really worried about performance on it. libgdx can build for everything pretty much.
XNA + MonoGame --- MonoGame's performance seems only slightly lower than libgdx, can build to most platforms. However I don't know much about XNA and I heard it won't be receiving future updates, but is quite stable? More information is welcome.
Citrus --- Don't have much information on Citrus either. AS3 game engine that can build for iOS, Android, Windows, Mac and more.
Haxe + OpenFL --- OpenFL (Haxe) builds to native on many platforms, not just to Flash. Windows, Mac, Linux and Android all get optional native deployment or OpenFL runtime called Neko which is in theory faster than Flash, and SDL 2.0 will enable iOS deployment soon(ish). -- Thanks to Bojan.
Qt-Project --- Just linking Qt project here, can build for everything and has a pretty big community with lots of third party libraries to help you even further.
Moai ---The only Lua engine that I know that can build for Desktop and Mobile. Only downside is the community isn't that big and documentation isn't the best. But if you can get passed those this is a great solution and the one I'm currently using.
Adobe --- Can't forget to add adobe here since it can build to everything that supports flash.
Unity3D --- Recently announced 2D integration looks very promising, should be released Q3-Q4 of 2013.
Cocos2d-x --- An open source engine. Supports JS, Lua, C++ and multiple platforms.
Html5 --- There seem to be a lot of emphasise on html5 mobile apps, here are just a few tools I found that can help port your html5 project to a platform:
Chromium embedded
Sencha
Phonegap
Appcelerator/Titanium
Icenium
So, I'd be happy if you could comment from your experiences with any engines and suggest which one you would recommend.
Thank you for your help!
EDIT: Since this topic is getting popular I'll be adding other options I've found over time. I suggest you choose what is most familiar to you and best for your project needs.
I would recommend V-Play (v-play.net) - it's a cross-platform game engine based on Qt for iOS, Android, Symbian, MeeGo, Blackberry10 and also can export for native desktop applications for Windows, Mac and Linux.
It's based on C++ but has a neat scripting support for QML & JavaScript. QML is a no-brainer to learn and can boost your productivity as less code is needed - just see the comparison with cocos2d-x(60% less Loc) or Corona(15% less LoC) for a comparison of the same games.
(Disclaimer: I'm one of the guys behind V-Play)
If you are into using Python, Kivy is a great solution these days. It compiles to all the platforms you ask for:
Kivy is running on Linux, Windows, MacOSX, Android and IOS. You can
run the same code on all supported platforms. It can use natively most
inputs protocols and devices like WM_Touch, WM_Pen, Mac OS X Trackpad
and Magic Mouse, Mtdev, Linux Kernel HID, TUIO. A multi-touch mouse
simulator is included.
Kivy uses lots of optimized code for graphics rendering (via Cython) so it is fast too.
Here is a speakerdeck that gives you some background and an overview (android specific).
How about HaxeFlixel? We have a great selection of demos, and of course support cross platform development via Haxe + OpenFL. This is an open source project hosted on GitHub. We support all major platforms (including iOS).
Here is my game framework Oxygine.
It is open source modern hardware accelerated 2D C++ framework for mobile and PC platforms.
Features: OpenGL(ES) 2, compressed textures, atlases, complex animations/tweens/sprites, scene graph, fonts, event handling, build tools, and others.
Can be built on top of SDL2 or Marmalade SDK.
In the basis of the engine there is a scene graph, that is similar to Flash one. To be short, You can call this as Flash for C++, but more comfortable and way faster. Initially it was developed for mobile platforms (iOS, Android), but can be also used for PC games.
No mention of App Game Kit (AGK) here so let me fill in the gap. It's a mainly 2D cross platform SDK allowing you to code once in either C++ or it's own "Basic" language. Version 2 just got over 400% funding on Kickstarter and will have full 3D support, Spine support (for 2D animated characters), bullet physics and whole bunch of other new features.
It already has Facebook, Twitter, a bunch of Ultrabook sensor commands, Box2D and more. I've been using it from the start and love it (can you tell?). No, I don't work for The Game Creators (the company that created it) although I admit I did do for a while making some apps.
One of the best features from my point of view is you can develop on Windows and broadcast from the IDE over Wi-Fi to any supported device, so while I'm coding I can (within seconds) test my code on iPad, Android, Windows, Mac or Blackberry Playbook.
If you have C# background. Have a look at Duality.
Duality is a flexible 2D game framework written entirely in C# –
and it’s here to make things a little easier for you. It provides both
an extensible game engine and a visual editor to match. There will be
no need for a level editor, testing environment or content manager
because Duality is all that by itself. And best of all: It’s free.
I'm just answering to give you some insights on how the SDL is used. As you said before it's not a game engine (it's just a library actually). Furthermore, it is not object oriented at all and you don't have some easy animation facilities (you have to code them by yourself).
How it works (I used the C version but I guess the Lua binding should be similar):
Include the headers needed to build the project on the platform you want.
Design your own game loop in which you will set up (at least) a whole event processing system, frame rate manager and a "screen cleaner (or updater)" (I'm insisting on the fact that you have to manually refresh your screen using the SDL_flip_screen routine which is something that is not one of your concerns at all with Corona).
Then, code your game using all the "mechanics" you made before.
The SDL is a low level library (don't expect to have an easy to use GUI framework or the storyboard framework of Corona for instance).
Finally, this library was used to port Civilization III to Linux, so yes it works but it will ask you a lot of energy to have something like you had with Corona ;)
PS: I am not a native English speaker, so please let me know if I wasn't clear :)
Gideros is a great Lua based 2d cross platforms engine, currently supporting both Android and IOS platforms, but more to come.
And it also has some great features as instant on device testing, auto scaling and auto image resolution to easily target various of screen sizes, as well as the option to extend each platform through native plugins.
You also have ShiVa3D, a serious competitor of Unity3D.
It uses Lua and supports many platforms from mobile to game consoles and web browsers.
Very intuitive to use and very nice UI to work with.
If I wanted to develop a graphical desktop application that would function in a manner similar to the web-based presentation software Prezi, allowing users to lay down objects on a board, resize them, and zoom in and out, what would be the best framework to use? How would it differ between the Mac and Windows?
I was thinking of using CoreGraphics on the Mac. Not sure what I would use on Windows.
