Hi all: I am trying to get animated stickers to work - regular stickers are find. I exported the motion sample with the car as an image sequence and added it to my sticker pack. The animation works fine, the app builds and works in the simulator and on the phone, where I can see the animation working. But then I go to tap on it or peel it and it refuses hot stick!!!! Has anyone got a remedy for this?? Thank you for your help!
Animated stickers won't stick
It appears I'm not the only one having this issue. It looks like even the Apple recommended export from Motion is making each individual PNG file around 419kb, which goes WAY over the limit. I bought Motion soley for this purpose - has anyone had any luck? I can't imaging those jib jab stickers are sticking to 500kb for animated stickers!
I think Apple recommended Motion because there wasn't another Apple product worth pointing devs to for exporting sequences, but obviously every graphic designer has MANY programs capabale of exporting PNGs.
I use Adobe Animate (ahem, Adobe Flash) Export > Export Movie > PNG Sequence. And to compress the sequence further, there's an app in the Mac Store called PNG Animator. It will export files named .png (don't try to name them .apng). Those files you can drop right into the Sticker Pack area of the project template, like you would non-animated PNG's. So in other words, you don't have to create a Sticker Sequence in Xcode.
I find thats a lot easier, and that program gives you some finer controls over the animation (for example, some frames can have a longer duration than others). Also the extra compression alone is worth it.
Similar experience, I found pngyu (https://nukesaq88.github.io/Pngyu/)useful to reduce the size of PNG output from motion.
Strangely though I have found even with a sequence of PNG's being under 500kb when compiled they exceed the size presented on disk, a warning is displayed with the compiled size which is 2x the size on disk.
I see this is old, but have you had any issues with exporting from Adobe Animate? I am following a similar workflow, but the exported PNG sequence does not look like the animation I have been testing (Control > Test), as I am working with symbols. The resulting sequence is awkward, and lacks the details of my symbols' sub-animations.
EDIT: This is a problem with my Movie Clip type symbols. Creating Graphic type versions of my symbols and swapping them into the animation fixed the export issue.
I am sorry icstello but I had no luck. Extremely frustrating that this is all so poorly documented. I"ll keep an eye out in case I see a better way to do it and will post here.
Rick I think your sequence is over 500kb. If so, it won't stick.
On that note, have you come across any similar issues with non-animated stickers? One sticker (supposedly 408 KB in its asset folder) was showing this non-stick behavior, so I suspected file size issues.
I dug around with the debugger/ Terminal a bit, and found that the file takes up 564 KB in the Simulator's file system. I assume Xcode is doing something weird under the hood and increasing its size at installation, but I'm not sure how to fix this without completely reworking the sticker.
Always test in your device. Never trust the Simulator. Pro tip for ya :-) Are you using PNG Animator to compile your pngs and export to the animated PNG? It’s a buck or so in the MAC App Store and well worth it! I never had any issues with sizes being different than what was stated after export. It also did some better compression I thought.
Make sure the size of your Animated PNG File is under 500kb
