Bounding boxes and a special announcement

We have released bounding boxes! This allows you to attach polygons to bones, then at runtime you can use the polygons to do hit detection, for physics simulation, etc. A bounding box is an attachment and goes in a slot, just like an image, so can be changed by animations or at runtime as needed. This can be useful when you have multiple items to equip which have a different bounding boxes. Also, a bounding box is translated, scaled, and rotated by the bone it is attached to.

We've been focusing on editor features, so currently some of the runtimes are missing bounding boxes, keyable draw order, and events. We will change gears and bring the runtimes up to date very soon!

We've been doing some R&D and have a pretty exciting feature to announce: free form deformation! While we didn't make the final Kickstarter goal, we know this is a very important feature and have decided to do it anyway. It will enable Spine to handle many types of animation that would otherwise be difficult. Also, images can be deformed to cover problematic areas such as joints, which would otherwise require new images to fix. FFD reduces the amount of art needed even further!

We are very close to having all the Kickstarter goals and stretch goals complete. All of the major tasks are done, we just need a bit of time to clear out the smaller tasks, then we can all celebrate! We really appreciate everyone's patience during the past 7 months while we've been working on Kickstarter goals. We are almost there!

      Awesome! Looking forward to the event time running time for cocos2dx!

      Great job guys!

      What an awesome feature!

      I love this tool, just need the right game project to include it in my dev chain.

      If the Game Maker Studio runtime(http://gmc.yoyogames.com/index.php…) gets closer to 100% support, that'll help motivate me to come up with something for sure. ;)

      Wow! That's really good news, can't wait to try out FFD in the future!
      Glad I backed this one as well as Spriter, you guys have done a great job.

      Thanks guys!

      @Rirath, FFD is an upcoming feature, we're still working on the details, it's a lot of work, so it will be some time before it's there. We need to get our hands on Unity 4.3 to say exactly what we can do with it, but anything that helps performance and workflow will be utilized.

    6. Creator Rirath on September 9, 2013

      Hip hip, hooray! Nicely done guys and I'm thrilled to see FFD officially make the list. Just to be clear, it's still an upcoming feature, right? (Checked the changelog and didn't see it.)

      I also second Kasprzak, backing Spine has been a wonderful decision. By the way, everything may still be too up in the air to know, but any thoughts on how the existing Unity runtime will play with the upcoming official 2D support?

    7. Creator Mike Kasprzak on September 9, 2013

      Yes wow. You've done great. If you ever need to Kickstart another marathon of new features, count me in. Obviously I already own Spine, but I'd love to see it grow even more.

    8. Creator Fredrik Schultz on September 9, 2013

      That's awesome! You've really created an amazing and powerful tool :)
