advice on an iphone game engine

The iPhone license forbids the download and execution of scripts or other executable content outside of their given APIs. Other than that there are several good free iPhone libraries (someone ported SDL over to iPhone, also there is http://oolongengine.com/ , and if your willing to spend some $$$ there is http://unity3d.com/ which comes highly recommended ).

People have ported over chipmunk onto the iPhone so you might be able to find it on the net ( though I doubt it, people seem to keep those proprietary).

Good Luck!

well, there arent many "2D" engines (other than torque, they have a free eval to play with, and cocos2d (free)).
for 3D, grab unity, its great.

im writing a 2D engine atm, but wont be done for a while ;)

for physics, box2d has a iphone port, as does chipmonk (which is used by cocos2d).

Well for 2D and 3D game take a look at SIO2 engine... its a free and open source 3d game engine for iphone and ipod touch, alot of commercial games have already been released with it and many more are currently in development using the engine.

There's also a large community based around it. For more information please take a look at:

Here's a quick list of the current features:

OpenAL: For 3D positional sounds (FX) and ambient music.
Theora: For realtime MPEG4 (ogv) playback.
Ogg: For MP3 style playback.
LUA: As the default scripting language that includes all the SIO2 API + all the OpenGL ES API, and uses SWIG to generate the necessary C wrapper. All OpenGL ES & OpenAL instructions are also available from LUA as well as the specific SIO2 API.
libJPEG: For fast JPEG decompression.
Zlib: To create and compress the SIO2 fileformat (.sio2)
libPNG: For fast PNG decompression.
Bullet: For Rigid & Soft Body physic, as well as for collision detection, collision feedback, custom sensors and collision triggers.

You can use SIO2 for free or commercial product, please read the SIO2 license agreement ( /SIO2_SDK/src/license/sio2.txt ). Basically the only thing that we are asking is that you mention SIO2 and/or our website somewhere in your project if its made available to the public in order to keep the SIO2 project alive.
