Spine-spritekit

I wrote a quick code for my own project that uses Spine 2D Skeletal Animation Tool (http://esotericsoftware.com) and iOS 7 SpriteKit for my own project. Though it does not fully support all the features of Spine 2D, it basically,

• Places Bones and Skot Attachments on SKScene (SpriteKit Scene object)
• Animates Bone and Texture (Slot Attachment) Timelines using SKAction for translate, rotate, scale and texture sequences
• Allows you to change the skin of a Skeleton before animation starts

Official runtimes are here: http://esotericsoftware.com/spine-runtimes

Until the official release of SpriteKit Runtime from Esoteric software, hope it's a quick starter for your projects if you are considering use of Spine and SpriteKit at the same time.

Usage Examples

Simple

+ (SKScene *) buildSpineboyLoopWithSize:(CGSize) size
{
    SKScene *scene = [[SKScene alloc] initWithSize:size];
    scene.scaleMode = SKSceneScaleModeAspectFill;
    scene.backgroundColor = [UIColor whiteColor];
    
    SpineSkeleton *skeleton = [DZSpineSceneBuilder loadSkeletonName:@"spineboy" scale:1];
    DZSpineSceneBuilder *builder = [DZSpineSceneBuilder builder];
    SKNode *node = [builder nodeWithSkeleton:skeleton animationNames:@[@"walk", @"jump", @"walk"] loop:YES];

    // place holder node for position adjustment
    SKNode *placeHolder = [SKNode node];
    placeHolder.position = CGPointMake(size.width /2, size.height /3);
    [placeHolder addChild:node];
    [scene addChild:placeHolder];
    
    return scene;
}

Two Skeletons

+ (SKScene *) buildComplexSceneWithSize:(CGSize) size
{
    SpineSkeleton *goblin = [DZSpineSceneBuilder loadSkeletonName:@"goblins" scale:1];
    
    // skin: "goblingirl"
    spSkeleton_setSkinByName(goblin.spineContext->skeleton, "goblingirl");
    spSkeleton_setSlotsToSetupPose(goblin.spineContext->skeleton);

    NSArray *tracks = @[
