Over-The-Shoulder Quick Tip
Q: If you have a fullscreen SWF how do you prevent the display from returning to normal size display when the user presses the ESC key? An example case where this would be useful is pausing a fullscreen game and displaying an in-game menu.
A: I thought overriding the default behavior might pose a security risk, however it is not restricted. Listen for the associated keydown event for ESC and call preventDefault() on it. Read the full article »
When porting an old project for iPad, I wanted to measure the FPS using the popular Hi-ReS! Stats tool from Mr. Doob:
I was unable to make the stats module show up. I confirmed that it existed on the display list by tracing from its update method, but it wasn’t being shown on the screen. After poking at it for a while I discovered that by drawing additional content into the graphics layer of the Stats object after it is initialized I was able to force it to be shown. There may be other solutions and this may be limited to my particular configuration, but if anyone encounters this, here’s a hack that works. Below are the 3 lines that I added after initializing the Stats object. Commenting-out the 3 lines and changing nothing else will cause the Stats object to disappear. I can’t explain why — the source code looks fine. Read the full article »
When an app is deactivated on iOS you can kill it instead of allowing it to continue running in the background (background running is the default behavior). Use the UIApplicationExitsOnSuspend property in the application configuration XML file:

iOS developers trying to use the AIR 2.7 SDK have noticed that they’re unable to publish with the following combination of features: GPU/Fullscreen/Landscape mode. Adobe has updated the AIR 2.7 SDK release to fix the problem (users confirm it was fixed for iOS only), but there has not been an announcement about it nor is there any date on the AIR download page to suggest that the SDK has been updated.

The app was published with Flash Builder 4.5 and the AIR 2.7 overlay.
Below are the download links in the various app stores: Read the full article »
I recently encountered 2 problems when migrating an AIR Flash Builder 4.5 project from a Windows 7 machine to a Mac. Both problems were related to external File loading and manipulation. I was going to write about my discoveries and solutions, but then did a little searching and found that Oliver Goldman (Adobe) addressed both problems in separate posts. So, instead of my original plan for this post, I’ll make a condensed post and dedicate it to Oliver Goldman. You can be sure I’ll be spending some time digging through his archives, especially his AIR Tips category: http://blogs.adobe.com/simplicity/category/api-tips Read the full article »
