Better Controller Support

[Percipient24]

Currently the game is supposed to work with OUYA, Xbox 360, and PS3 controllers, along with the keyboard.

Keyboard support looks like this:

Right side: Enter to select, Backspace to back out. ; joins/leaves character select. Arrow keys move. Quote punches. Enter jumps (while moving).

Left side: 1 to select. Tab to back out. Q joins/leaves character select. wasd moves. Tab punches. 1 jumps (while moving).

P pauses while in-game.

---

It should support any controller.
It should allow controller configuration (ie, press buttons to set buttons).

@ahollenbach - What type of controller were you using (that didn't work)?

I actually cracked out the Ouya controller for this one 😜

Interesting. We had issues with the OUYA controller on Mac - the touchpad would cause the mouse to move towards a corner forever, which made using the machine at all difficult. Maybe they released updated drivers recently?

I've got plenty of those, so I'll give it a go later tonight and see what's up.

I didn't forget about you, @ahollenbach!

Ugh, what a mess this is! :-P

Apparently on OSX 10.11 one isn't allowed to install unsigned drivers. Of course there are work-arounds, and I got some of the way there before hitting a brick wall.

First, I found this forum post ( http://ouyaforum.com/showthread.php?3185-Ouya-controller-input-on-computer-macosx ), and tried the drivers there. It didn't work. Even the suggested command:

sudo kextload /System/Library/Extensions/OUYAGameController.kext

Gave an error along the lines of:

/System/Library/Extensions/OUYAGameController.kext failed to load - (libkern/kext) not loadable (reason unspecified); check the system/kernel logs for errors or try kextutil(8).

Troubleshooting that error lead me to this conversation ( pje/WavTap#60 ), which suggested the following steps:

1. Restart Mac and hold Cmd + R while booting.
2. Use the menu bar to open Utilities > Terminal
3. Run the command csrutil disable
4. Reboot the system and run the sudo kextload... command from above.
5. Profit.

That worked - now the game at least recognizes an OUYA Controller is attached. Problem is, while the buttons work just fine, the thumbstick and trigger axis values are all kinds of strange. I think it's because libGDX expects its axis values to come in as floats, while that driver is reporting them on a range from 0x0000 to 0xFFFF where 0x8000 is the center.

I naively tried to take the 'float' I got, send it to binary, and tried to reconstruct the 0x0000-0xFFFF from there, but even that seems broken/wrong.

I'm going to write an email to the driver creator, and see what it would take to change axis from int-reporting to float-reporting - or if he has any other suggestions.

Unless there's further progress, I recommend not using OUYA controllers on the Mac. :-/

Thanks for the update! I'll see if I can get another controller up and working.

[Percipient24]

It works!

The creator of the OSX driver responded to my email with a new version of the driver (which I've forked into ChainGangChase to keep a snapshot).

With that installed and #42 going, the OUYA Controller will work on OSX 10.11!

Thank you @edmundmk!
