Question ChromeOS input questions

I have successfully built my game for ChromeOS, but I'm having issues with input. The following code works on all other platforms when using the arrow keys or 'w'/'s'.

Code (CSharp):

1. movement = Input.GetAxis("Vertical") * target.transform.forward;

Note that this code is set up using the old input system. I tried enabling and disabling the 'ChromeOS input emulation' toggle.

The following code works on all platforms including ChromeOS:

Code (CSharp):

1.             if(( Input.GetKey(KeyCode.A)) || ( Input.GetKey(KeyCode.LeftArrow))) {
2.                 //code to move camera
3.             }

So I see a few options for fixing this:
1. Upgrade to the new input system. I'd like to do this at some point, but it's likely going to take some time, so I'd like an easier solution in the mean time if one is available.
2. Update the first bit of code, maybe with a platform define to use keycodes rather than getAxis(). Our controls aren't well tuned for gamepads so the getAxis call isn't as important as in some other game types.

Questions:
1. Am I missing any easy ways to get this working on ChromeOS? Should getAxis work?
2. Is there a platform define for ChromeOS specifically, or just UNITY_ANDROID?
3. I don't see build targets specific to ChromeOS. In order to build for ChromeOS from a script, would I have to set the build target to Android, and have the build and player settings set correctly, or are there options to set those in the script?

Thanks.

 

Tomas, Thanks for the detailed response. That GetAxis call is definitely not working for me. I'll try to put together a bug report for that.
