A short while ago one of our intrepid Deepworlders asked if I would post a tutorial on creating a character’s walk cycle. I’d love to do so, and I plan to - but once I started writing out the steps, I...

    I got up to the part where you rotate the ball at frame 30, but it doesn't move when I click on play...

    A couple years ago, I once took a course in animation under a retired professional who once worked for a company in the late 1950s and animated a ball bouncing using cels and acrylic paint.

    I was just wondering if you have tried traditional animation and which one you prefer and why, if you don't mind me asking.

    Make sure to go back to frame 0 before you play - otherwise the timeline will keep playing toward infinity. You can turn on the Loop feature to prevent that from happening.

    I made some clay animation videos from when I was around 11 through high school, and while it was fun to physically build the worlds of my little movies, I much prefer the computer approach. Being able to tweak and improve animations after the fact is a huge gain. I suppose you can do that with cel animation too, but I also like not having to create all of the inbetween drawings; even with computer assistance, animation is very time-consuming. And many of the tools allow you to do traditional frame-by-frame drawings anyway :)

    I cant install Spine on my windows vista. @quinnstephens
  • quinnstephensquinnstephens Posts: 464Administrator
    If you guys are having Spine issues, try posting a question on the Esoteric forums. The developers are really responsive.

    thanks @quinnstephens for a fast reply

    I downloaded and installed this and when I try to open the application (there are two versions of the application) one tells me I need X11 and the other tells me I need a Java SE6 runtime.

    I'm super paranoid about installing new stuff onto my computer. I know I don't want to install the X11 thing. But is the runtime thing something safe and harmless?

    *tries to not look like a crazy paranoid technophobe*
  • quinnstephensquinnstephens Posts: 464Administrator
    I use the "system Java" version of Spine, which is what I'm guessing requires the Java SE 6 runtime for you. I would go ahead and install it. The only thing you should be careful of with Java, as far as I know, is running applets on potentially malicious sites (much like Flash). But you can disable it in your browser if it makes you feel better.

    Okay.

    Is this compatible with flash 7?

    Is this compatible with flash 7?

    Do you mean the exported animation data?
  • GuardofthedragonGuardofthedragon Stargate CommandPosts: 2,623Member
    I mean the program in general

    Not sure what you mean. Spine is a standalone Java app. It doesn't hook directly into Flash or anything, although you could export graphics from Flash and animate them in Spine. You can also run Spine animations within a Flash game or app, by using one of the Actionscript 3 runtimes people have put together: http://esotericsoftware.com/spine-runtimes

    Flash 7 is pretty ancient by this point, though - didn't it use Actionscript 2? If you wanted to create an app in Flash 7 and use Spine data, you'd have to write your own Actionscript 2 runtime, since I'm sure no one else is going to. Sounds pretty painful to me :P If you just wanted to do your graphics in Flash 7 and export them as .png files to bring into Spine, though, I don't see a problem there.

    Okay I have installed the java runtime thingee. Now when I try to follow the instructions in the animation post and trace my way to the ball.png file in order to open it, it shows as greyed out and I'm unable to select it. (In fact it appears all individual files are showing as greyed out -- I can only click on folders.) Do I need to restart or something? I'm gonna restart just in case.

    *scowls and refuses to feel like an idiot, mostly*

    Edited to add:

    Okay, huh. Still not able to open the ball.png file. I even put it into the "Spine Trial" folder. Cannot open any of the .png files included by the Spine program itself in the example folders. Weird! Ah well ...
  • quinnstephensquinnstephens Posts: 464Administrator
    Select the folder - not the file - and Spine will import everything in that folder.
  • SirentistSirentist Posts: 9,076Member, Moderator, Arbiter
    Oh. Yeah I just went back to your post and reread and saw that. And people wonder why I'm a technophobe. Which I'm totally not. *scowls*

    Oh! Silly Silly me. Java 7! Not Flash 7! Silly Guard.
  • quinnstephensquinnstephens Posts: 464Administrator

    Ah, that makes more sense. I don't know the answer, but that's a good one to direct to Esoteric Software on their forums.
