[TUTORIAL] Forza/G27 MaxAim DI Script (with clutch)

[fbmrider86]

Hi folks, long time lurker/tinker-er here. Awhile back I came across a smokin' deal on a G27 and after having so much fun playing Forza with a controller, I'm so glad I stumbled across the TitanOne-style devices. After messing around with some various snippets of code from here and the "other" site, I feel I've compiled a great collection of all of the "wants" of the typical G27/Forza fan (sorry, no FFB!).






******************************** IMPORTANT ********************************

You must utilize Controller Layout 10 for this code to work properly!

*****************************************************************************

• This code changes some of the typically seen settings for the G27 and Forza games to include as many functions native to the game(s) as possible.
• YOU MUST USE Controller Layout 10 for this script to function properly, DO NOT USE Layout 4/6!!!
• Script has been fully tested utilizing Forza 4 (XB360) and Forza 5 (XB1).
• Script is confirmed working both inside GTuner or utilizing MaxAimDI standalone application.
• D-pad and "lettered" buttons are mapped to their respective buttons on the shifter.

• Features Include:
• - Adjustable steering deadzone ( controllable via 'wheelSlop' variable )
• - Fully managed Brake and Accelerator pedals
• - FULLY FUNCTIONAL Clutch Pedal (no longer an 'on/off' button, it is now mapped to an appropriate axis, allowing for a more realistic take off and proper clutch 'slipping'.
• - Fully working six speed H-pattern shifter (utilizing J2Kbr's shifter code)
• - Fully working Emergency Brake (mapped to Button 4) - Now complete with J-turns!
• - EXTRA: "Line Lock" function - Allows for a certain amount of brake to be applied at the press of a single button (mimics the usage of an actual line-lock in drag racing, which locks the front brakes but allows the rear wheels to spin up and burnout).
• - This is also fully adjustable, from 0 to 100% of braking applied during its activation.

Thanks to all of the folks who have made this possible, especially (and obviously) J2Kbr. You're a great asset to the sim-racing fans!
