Orx - Portable Game Engine
iPhone, uPhone, he/shePhone?
19 February 2010

Erm, sorry for the lack of inspiration for the title. -_-


So orx on iPhone/iPod Touch is coming nicely. So far all the core features are available. 

As for the plugins, the rendering works correctly (OpenGL ES 1.1 for now, so no support for shaders) but text aren't supported yet.


The mouse plugin works and simulate a one-button mouse given the touch information the device provide.

The full events (including multiple touches) are also forwarded by orx if you need them (just add an event handler on the event type orxEVENT_TYPE_IPHONE).


Next step: sound support. This looks very messy from the bits of code I could analyze so far, so it might take a week or two, maybe more.

Lastly I'll add text support with custom bitmap font support. The custom bitmap font support will then be added to the other architectures (win/linux/mac OS X).


I'll probably also forward the accelerometer events and feed their values to the joystick plugin (X, Y & Z axes) so that they can be used directly through the generic orxInput module.


When all this is done, before releasing a new version, I'll try to make a couple of small optims here and there and maybe finish the SDL/OpenGL/OpenAL plugins that will then become the main plugins for orx. :)

New release!
26 January 2010

orx v1.1 has been released!


There are a lot of changes between v1.0 and v1.1. You can find an almost exhaustive list in the CHANGELOG file from any package.


There are 3 majors changes that you need to pay attention to, when updating to v1.1:

- The config property WaveNumber for spawners has been renamed WaveSize 

-  The gravity is now expressed in the same unit system as every other physical values. If you didn't change the DimensionRatio property for Physics in your game, you then need to multiply your previous gravity by 100 (the default DimensionRatio being 0.01)

- As now you can specify empty values for any config property (useful when overriding), when you use blocks for values, the first block marker ["] has to be one the same line as the asignment character [=].



Beside these major changes, a lot of things have been added since the previous release, here's a list of the main ones:

- Added custom animation events, handled from config files (very useful for synchronization)

- Clocks can now be created from config and directly associated to objects, ie. time stretching can easily be done on a per object basis

- Added easy timers based on clocks with optional repetition counters

- Added raycasts to test against physical bodies

- Objects can now have a custom gravity that can be changed on-the-fly

- The display resolution + windowed/fullscreen can now be changed on-the-fly

- Dynamic physical objects can now be part of an object hierarchy, they will compute their position given their parent movement and the results of the physical simulation 

- More robust logic/physics/display loop with no more 1-frame delay

- When using the ChildList property of objects, the hierarchy can be inspected at runtime with orxObject_GetChild() / orxObject_GetSibling()

- AutoScroll/DepthScale now works correctly with objects that have bodies

- Added orx_WinExecute() convenience wrapper when executing orx from WinMain() (ie. for windows console-less games)

- A bunch of optimizations and misc fixes =)


If you have any bug report/comment/feedback, you know where the forum is!


Enjoy! =)


PS: Thanks to smchronos for building the msvs2005 binaries! :)

Mushroom Stew has been released! Cool


The game runs on Windows, Linux & Mac Os X. The level editor as well as the full source code is included.


If you want to share your user-created challenge levels, please contact me and I'll add them to the archive. 


Thanks to all who helped! Laughing

Hacking Box2D
20 December 2009

I'm still working on my entry for the TIGSource compo. It allows me to really improve Scroll.


But also, it made me hack Box2D so as to support gravity on a per object basis. I also made a very ugly hack to allow tagged objects to not slide on 45°+ slopes if needed. All this is already submitted on the svn repository.


In the config file you can now find 2 new properties: AllowGroundSliding which defaults to true and CustomGravity which defaults to none, meaning the world gravity is used by default.

The custom gravity applied on an object can also be modified at runtime and I'll probably use it in my TIGSource entry. :)
