On Mac "left shift" and "right shift" trigger both Keys

Archived Forums Questions & Answers

I have noticed on my current Mac builds that if I bind "left shift" or "right shift" Unity behaves as if I have hit both shift keys whenever either is hit. I'm using the smaller Mac keyboard.

Specifically, if I put in this code: 

        if (Input.GetKeyDown(KeyCode.LeftShift)) {
        Debug.Log("Left Shift");
    }

    if (Input.GetKeyDown(KeyCode.RightShift)) {
        Debug.Log("Right Shift");
    }

Unity console will return both "Left Shift" and "Right Shift" each time the key is pressed. This also happens if I specifically bind the "left shift" and "right shift" keys to an input in the Input Manager.

If I build this same project to PC, the shift keys are correctly differentiated.

Anyone have an idea of a workaround for this? I'm working on a pinball game and it's fairly universal that you use the two shift keys for the flippers.

EDIT: Well, I just got an e-mail back from Unity QA and they say this is working as designed since Mac doesn't send different commands for each key. I beg to differ since I've seen games that support both keys. However this might be a limitation based on how Unity polls for keys.

I submitted a bug to FogBugz, it is ID: 398952

Interestingly, Unity does distinguish between the two shifts correctly outside of gameplay in the Input Configuration menu prior to the game's launch via the Mac Builder. This is clearly an actual bug with the Unity Editor and Mac Player - I wrote back to the QA team.

Unity QA got back to me, I sent a sample project; assurances this will be addressed.

Unity QA let me know this is an anticipated fix for 3.5. A bit late for my game, but hopefully it will come soon.

Confirmed the bug is fixed in 3.5

This bug will be fixed as part of the 3.5 release. It will not be fixed in Safari 3 and Firefox 3, but only in later browsers.

Hi Graham, do you know if it's possible to get early access to 3.5? My game is coming out soon.

If what you say is true I don't think there would be a simple workaround. Best thng I could advice is filing a bug report. It must be (I naively think) an easy bug to quash, seeing how the keys obviously give the machine different input signals. Strange.

Especially since it used to work properly in a previous version, although it's possible OS upgrades might have some effect.

It has to be multiplied by the original rotation if you do it this way. Quaternion originalRot = transform.rotation; transform.rotation = originalRot * Quaternion.AngleAxis(degrees, Vector3.Up);
