Linux XBox 360 controller axis mapping incorrect

[Cale]

Whether I'm using the kernel xpad driver or the userspace xboxdrv, the game seems to interpret the axes on my XBox 360 pad incorrectly. With xpad, which is what I normally use, and which usually works fine in most other games (though I've run into a few with similar issues, notably Ascendant), the left trigger seems to be acting as what ought to be the right stick Y axis. This makes looking around difficult, especially as the trigger can't produce negative values, so I can only look roughly downward.

It would be nice to have controller button and axis mapping in the configuration, just to make sure things can't go wrong like this.

Could you possibly give more information on your configuration?

[Cheeseness]

Also, are you using the 1_4_beta branch?

[Cale]

I had been using the non-beta version of the game, but I just tried the beta and it appears identical.

I'm running Linux Mint 15 with kernel 3.8.0-19-generic on x86_64.

jstest-gtk indicates that I have a Microsoft X-Box 360 pad connected as /dev/input/js0. By playing with the controls and looking at the mapping reported, the mapping is as follows:

• 0: ABS_X - Left stick X axis
  
• 1: ABS_Y - Left stick Y axis
  
• 2: ABS_RX - Right stick X axis
  
• 3: ABS_RY - Right stick Y axis
  
• 4: ABS_Z - Left trigger
  
• 5: ABS_RZ - Right trigger
  
• 6: ABS_HAT0X - Pad X axis
  
• 7: ABS_HAT0Y - Pad Y axis

I've found that I can (at least temporarily) work around the problem by changing the order to:

• 0: ABS_X - Left stick X axis
  
• 1: ABS_Y - Left stick Y axis
  
• 2: ABS_Z - Left trigger
  
• 3: ABS_RX - Right stick X axis
  
• 4: ABS_RY - Right stick Y axis
  
• 5: ABS_RZ - Right trigger
  
• 6: ABS_HAT0X - Pad X axis
  
• 7: ABS_HAT0Y - Pad Y axis

At which point the game works properly. Perhaps I'll try just leaving it configured this way for now, and see if I run into issues elsewhere.

Let me know if there are any other system-related details I can give.

Thanks for the info! Hopefully we'll be able to get a clearer picture of what's going on and either solve it in the game or provide a simple workaround for users.

Out of interest, what does jstest say that the device is called?

Be aware that config and saves are not backwards compatible. If you do want to head back to the main branch, you should probably move/remove ~/.config/unity3d/Over\ The\ Moon/The\ Fall/prefs to get a fresh configuration file.

cale@ender:~$ jstest /dev/input/js0
Driver version is 2.1.0.
Joystick (Microsoft X-Box 360 pad) has 8 axes (X, Y, Z, Rx, Ry, Rz, Hat0X, Hat0Y)
and 11 buttons (BtnX, BtnY, BtnTL, BtnTR, BtnTR2, BtnSelect, BtnThumbL, BtnThumbR, ?, ?, ?).

Thanks for the heads up about the configuration and saves.

[Cheeseness]

Cheers.

Out of interest, do you happen to own any other games that use InControl (like Hand of Fate for example)?
