My students are working on an app involving arrow keys causing movement of an object. We are using the arrowKey message. It works fine in Windows, but on a Mac, the arrow keys do not seem to trigger the arrowKey message when developing the app. (If it is deployed as a stand-alone app, then it works fine on a Mac). Is this a known issue with LiveCode on the Mac? We're using LiveCode 8.1.1 Community Edition.

Hi,
It sounds like you have to set the textarrows to false
Best regards

I just tried setting the textarrows to false, but it didn't make any difference. What I am trying to do is this:

On a card, I have an image. In the script for the card, I have:

on arrowKey theKey
if theKey is "right" then move image "imgStar" relative 10,0
end arrowKey

When I put the program into run mode (Browse tool), in Windows, pressing the right arrow key moves the image right. On a Mac, pressing the right arrow key does nothing. I've put a breakpoint in the arrowKey handler and it is not triggered on the Mac, leading me to believe the arrowKey event is not running. However, if I deploy it as a standalone app, then it works fine regardless of if it's in Windows or on a Mac.

Hi dvermes,

just made a test on macOS 10.12.2 with LC 8.1.2 RC3 and your script works as exspected in the IDE!
Sure there are not other (front-/backscripts) in the way in your IDE?

Klaus,

I'm not sure. What sort of front/backscripts should I be looking for? My stack has a stack script and the card has a card script...

Thanks,

Doug

Hi Doug,

if this also happens right after starting LC then there is probably no script in the way.
You could send me the stack if you like and I will take a look: klaus AT major-k.de

Sorry, I was wrong, setting textarrows has no effect
I tested your script with LC community 8.0.0 and Indy 8.1.1 and it works.

It looks like it's a LiveCode bug. I was running LiveCode 8.0.1 Community Edition on a Mac and the arrow keys did not work. I just downloaded LiveCode 8.1.2 RC3 Community Edition and it works fine on a Mac. Thanks to Klaus for helping me troubleshoot!
