Spine Skeletal Animation Integration And Faster iOS Packager in v0.9.5

Posted on August 3, 2014

A number of users have asked if 2D games like the award winning Shank or Street Fighter could be created in GameBuilder Studio. In Shank there is gameplay where the main character jumps in the air and shoots enemies or changes weapons on the fly and slices enemies in hand to hand combat. This type of gameplay would be very difficult to create without some sort of skeletal animation system that interacts with your 2D scene. Now that Spine is officially integrated into GameBuilder Studio it is possible. If you are not familiar with Spine here is a quick intro video.

it also opens up additional ways to monetize your game content by offering players unlock-able character packs and wardrobe upgrades that would be so simple to swap out on the fly while the game is running.

Spine Plugin Integration

Spine Plugin Integration

This is a pretty extensive Spine integration with support for Skinning, Animation mixing/layering, and Procedural Bone manipulation. Equip characters with different types of weapons, change a characters look and feel completely using the same skeleton and animations, and dynamically change positions or directions of bones. All of this without having to write a line of code or worry about integrating the Spine runtime into a game engine yourself.

Spine Renderer In GameBuilder Studio

The Spine renderer in GBs works with Live Reload so if you change a characters' animation, change an attachment on a character, or change the artwork in the sprite sheet file attached to the skeleton just save over the existing data files on your file system and the updates will instantly appear in the editor.

When you import your Spine skeleton into GBs and drag the asset onto your scene it will create the Spine Renderer, a Spatial, and a Sprite Sheet if one was either included in the .skel data file from Spine or in the same folder as the .skel data file with the same filename. Make sure to follow the Spine plugin guide tutorials.

We backed Spine on kickstarter last year and have watched it develop into a really great animation tool that opens up a ton of possibilities. Keep in mind that Spine skeletal animations don't only have to be used for character animations. This is a PRO user only feature.

Faster iOS Packager

Adobe AIR Faster iOS Packger Toggle

The underlying compiler has been upgraded to Adobe SDK v14.0 which comes with the new iOS packager. This reduces packaging times quite a bit. It went from 5-10 min to about 59 seconds in our tests. This new feature has to be turned on in the Publish settings window. It is still being tested so if you run into an error when packaging up your game for a mobile device with this setting turned on, just revert back to the old packager by unchecking it.

Regarding the license server connection issues some of you guys have been having while on secure networks. We apologize to those that have had issues connecting. The license server connection functionality will be changing in the next release which should be out sooner than later.
