Using multiple keyboards

Support

Hi Chris,

I am trying to set up a multiplayer game where separate keyboards control
two avatars on the same screen. When I tried to start the demo you sent
initially, I got the ‘multiple matching HID devices’ error pasted below. I
was able to run the demo by specifying preferred_location_id as prompted.
My question is if I want to allow for input from two keyboards, is there a
way to read key presses from both?

ERROR: Found multiple matching HID devices for “joystick”:

Device #1

Product: Apple Internal Keyboard / Trackpad

Manufacturer: Apple Inc.

Location ID: 2152726528 (0x80500000)

Device #2

Product: Magic Keyboard with Numeric Keypad

Manufacturer: Apple

Location ID: 343706896 (0x147c8d10)

Device #3

Please set the “preferred_location_id” attribute to the Location ID of the
desired device.

Thanks,
Ruidong

Hi Ruidong,

Yes, you can use multiple keyboards. You just need to define two separate USB HID devices and set preferred_location_id on each of them.

Cheers,
Chris

Got it to work with two keyboards now. Thanks so much for your help!
