Animate CC does not import/consume a spritesheet.
The spritesheet image does get imported as it is, but creating animation out of it (manually) would be tedious.
You can parse the spritesheet metadata and use masking to set up the different frames using JSFL if you really need to.
Why would you want to import a spritesheet in Animate anyway?
Thank you for replied. What is JSFL?
It is because of i use another software for making spritesheet, how could i import it into Animate CC? Could i use a Gif file?
* Another question: Can i make cartoon animation with Animate CC? (About 5-10 minutes)
Is there any tutorial for it? I can't find any good tutorial for Animate CC, thank you
If what you are making is just an animation, make sure it's an ActionScript 3 FLA, and not HTML5 Canvas, so that you can then use all of the ink modes and filters.
Spritesheets are how you can get some other programs to do what Animate can do without using spritesheets. If it's an AS3 animation there is no reason to need spritesheets. If you happen to have the frames that went into making the spritesheet, use those frame images instead.
If you were making a code driven game, and you were using Stage3D (say with Starling), then there are performance advantages to using spritesheets, and Starling does work with those. But if you are just making a cartoon, no need to use spritesheets.
I'm sure there are a lot of YouTube videos on making a cartoon. Make sure to search for Flash Pro, not just Adobe Animate, there will be a lot of tutorials that were made before the name was changed.
One thing to know, there is a limit of 16000 frames, but that would be enough for over 11 minutes at 24 frames per second.
If you need to work in HTML5 Canvas for your project, you could bring in an image sequence and let Animate make the sprite sheet for you.
If your images are numbered sequentially, when you import one of them to the stage you will have the option to import all sequential files; just click "Yes" when prompted, and it will import all of the images as successive keyframes.
In Publish Settings, you can set your images to be exported as a sprite sheet: Create HTML5 Canvas documents in Animate CC
Thank you guys, what if i want to make a short 3-5 minutes cartoon video to publish on Youtube. Should i work on HTML5 Canvas or ActionScript 3 FLA or something else?
Since you'll be exporting as a video you should stick with AS3. You can still import an image sequence, you just won't have to worry about sprite sheets.
When you're done with your animation and ready to export the video, you can follow these instructions: Export Video with Animate CC
