iTGE 0.7 (ref .zip of repo from 9/2/08 1:04 PM)

Nearly all TGE's rendering has been both implemented and tested. There remain a number of yet to be implemented items as well as items that have been implemented, but not yet tested. Any feedback on the latter would be great.

Setup

A Mac xcode project can be set up in the same folder as the iPhone xcode project, to allow running the same code on the Mac for reference and to compile the scripts. The iPhone simulator can be run from a local dedicated Mac Torque server, so the remote Torque debugger or Console is available for debugging, along with the xcode debugger. It hasn't been tested yet, but I'm assuming the hardware can be run in the same way.

As it is for iTGB, the screenshot and other development support tools (creator and show stuff) will not be implemented on the iPhone build and will be actively #if'd out in order to get the memory footprint down as much as possible.

The starter.racing, starter.fps, and demo all 'work'...that is, they run and virtually all the features are working (except terrain texture blending). The scripts need more modification to allow the touchscreen interface to do things like access options and other key-mapped inputs.

Not yet implemented

* Low level stuff
o Fix glColor to handle colors in and out of begin/end and other unsupported opengl states.
o Fix terrain texture blending, create workaround for only 2 texture units.
o OpenAL sounds (TGB implementation should drop in).
* iPhone specific features
o Accelerometer mapping to 3-axis joystick.
o Pop-up keyboard for text entry.
o Screen auto rotation.
* Optimization
o Optimize frame rate -- tune opengl-es stuff and framebuffer handling.
o Optimize engine size -- strip editing/offline non-game code from build.
o Verify multiplayer online gameplay, currently runs single player from local server.
* Theora
* QuadBatch - looks unused
* PopUpMenu
* ExecuteThread - Single threaded only at the moment
* VectorField - looks unused
* guiEffectCanvas - looks unused
* Net code - working in iTGE
* Screenshots - no screenshots from iPhone, won't be implemented
* GUICanvas backRender/frontRender - looks unused, implemented in iTGE if needed
* Screen AutoRotation - Apple specific new code


Inputs are fully mapped

* Accelerometer
* Gesture recognition
* Touchscreen buttons


Known issues

* Apple "optimizes" PNG files as a build step in Xcode, TGX png decoder has problems with some compressed PNGs. This can be ignored (there is a work around in place), disabled (change settings in your Xcode build) or assets can be put into a zip file to avoid this.
* Framerate slowed by script calculations thrashing CPU cache
* Framerate slowed by image size, should resize images for 480x320 resolution
* Framerate slowed by dynamic casting
* Documentation lacking
* Script Files and Fonts must be pre-compiled on Mac or PC (this is to comply with Apple's SDK EULA, no scripts compiled at runtime)
* Theora and Ogg/Vorbis not supported
* OpenAL use wav files only
