spine-spritekit
非官方的iOS 7 SpriteKit运行时，用于Spine 2D (http://esotericsoftware.com)
官方运行时在这里：http://esotericsoftware.com/spine-runtimes
我为自己的项目编写了快速代码，该项目同时使用SpriteKit和Spine 2D。尽管它并不完全支持Spine 2D的所有功能，但它基本上，
- 在SKScene (SpriteKit场景对象)上放置Bone和斯柯特附件
- 使用SKAction对骨时间线进行动画，包括平移、旋转和缩放序列
直到esoteric软件的SpriteKit运行时官方发布，如果您考虑同时使用Spine和SpriteKit，它可能是一个快速启动器。

更新
2013年10月22日
- 附件（插槽）动画
- 允许按骨骼（SpineSkeleton的spineContext属性）访问spine-c结构
- 为'attachment'而非'slot'覆盖贴图

构建和运行
一旦您已经克隆了此项目，别忘了初始化和更新spine-runtimes子模块，这是官方运行时。
$ git clone https://github.com/simonkim/spine-spritekit $ git submodule init $ git submodule update
从Xcode 5打开演示项目
- 位于Spine-Spritekit-Demo/Spine-Spritekit-Demo.xcodeproject
- 构建和运行
如何使用
下面的示例假设骨（.JSON）、图集（.atlas）和纹理图集图像（.png）被包含在应用包中。例如，演示应用包含以下文件用于spineboy和goblins骨骼：
- spineboy.json
- spineboy.atlas
- spineboy.png
- goblins.json
- goblins.atlas
- goblins.png
此外，示例中使用的骨骼名称参数用于通过附加扩展名（.json和.atlas）解析骨骼名称和图集文件
简单示例：为骨骼动画
// Use DZSpineScene class to load skeleton JSON, atlas, and texture image files with scale parameter to build an SKScene object
DZSpineScene * scene = [[DZSpineScene alloc] initWithSize:size
skeletonName:@"spineboy"
animationName:@"walk"
scale:1];
// adjust root position
scene.rootNode.position = CGPointMake(size.width /2, size.height /3);
scene.scaleMode = SKSceneScaleModeAspectFill;
// Present the scene to an SKView object
SKView * skView = (SKView *)self.view;
[skView presentScene:scene];
为骨骼序列动画
+ (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;
}
在动画和皮肤之间延迟的序列动画
+ (SKScene *) buildGoblinWithSize:(CGSize) size
{
SpineSkeleton *skeleton = [DZSpineSceneBuilder loadSkeletonName:@"goblins" scale:1];
// skin: "goblin"
spSkeleton_setSkinByName(skeleton.spineContext->skeleton, "goblin");
spSkeleton_setSlotsToSetupPose(skeleton.spineContext->skeleton);
DZSpineSceneDescription *sceneDesc = [DZSpineSceneDescription description];
NSArray *tracks = @[
// goblin
@{ @"skeleton" : skeleton,
@"scale" : @(1),
@"position" : NSStringFromCGPoint(CGPointMake(0, -200)),
@"animations" : @[
@{@"name" : @"walk"},
@{@"delay" : @(1.5)}, // delay for 1.5s
@{@"name" : @"walk"},
@{@"name" : @"walk"},
@{@"delayUntil" : @(5)}, // delay until 5s from the beginning
],
@"loop" : @(YES) }
];
[tracks enumerateObjectsUsingBlock:^(NSDictionary *track, NSUInteger idx, BOOL *stop) {
[sceneDesc addTrackRaw: track];
}];
NSArray *nodes = [sceneDesc buildScene];
SKNode *placeHolder = [SKNode node];
placeHolder.position = CGPointMake(size.width /2, size.height /3);
[nodes enumerateObjectsUsingBlock:^(SKNode *node, NSUInteger idx, BOOL *stop) {
[placeHolder addChild:node];
}];
SKScene *scene = [[SKScene alloc] initWithSize:size];
scene.scaleMode = SKSceneScaleModeAspectFill;
scene.backgroundColor = [UIColor whiteColor];
[scene addChild:placeHolder];
return scene;
}
多骨架场景
+ (SKScene *) buildComplexSceneWithSize:(CGSize) size
{
SpineSkeleton *goblin = [DZSpineSceneBuilder loadSkeletonName:@"goblins" scale:1];
// skin: "goblingirl"
spSkeleton_setSkinByName(goblin.spineContext->skeleton, "goblingirl");
spSkeleton_setSlotsToSetupPose(goblin.spineContext->skeleton);
DZSpineSceneDescription *sceneDesc = [DZSpineSceneDescription description];
NSArray *tracks = @[
// spineboy
@{ @"skeleton" : @"spineboy",
@"scale" : @(1),
@"position" : NSStringFromCGPoint(CGPointMake(-80, -100)),
@"animations" : @[
@{@"name" : @"walk"},
@{@"name" : @"walk"},
@{@"name" : @"jump"},
@{@"name" : @"walk"},
@{@"name" : @"jump"},
@{@"delayUntil" : @(8)},
@{@"name" : @"jump"},
@{@"name" : @"walk"}],
@"loop" : @(YES),
@"wait" : @(YES) },
// goblin
@{ @"skeleton" : goblin,
@"scale" : @(0.8),
@"position" : NSStringFromCGPoint(CGPointMake(30, -200)),
@"animations" : @[
@{@"name" : @"walk"},
@{@"name" : @"walk"},
@{@"name" : @"walk"},
@{@"delayUntil" : @(8)},
@{@"name" : @"walk"},
@{@"name" : @"walk"},
],
@"loop" : @(YES),
@"wait" : @(YES) },];
[tracks enumerateObjectsUsingBlock:^(NSDictionary *track, NSUInteger idx, BOOL *stop) {
[sceneDesc addTrackRaw: track];
}];
NSArray *textures = @[@{ @"skeleton" : @"spineboy",
@"textureName" : @"goblinhead4spineboy",
@"attachment" : @"head"}];
[textures enumerateObjectsUsingBlock:^(NSDictionary *texture, NSUInteger idx, BOOL *stop) {
[sceneDesc addCustomTextureRaw: texture];
}];
NSArray *nodes = [sceneDesc buildScene];
SKNode *placeHolder = [SKNode node];
placeHolder.position = CGPointMake(size.width /2, size.height /2);
// Give zPosition to each character so they don't mix sprites in draw orders
CGFloat __block zPosition = 1000;
[nodes enumerateObjectsUsingBlock:^(SKNode *node, NSUInteger idx, BOOL *stop) {
node.zPosition = zPosition;
[placeHolder addChild:node];
zPosition += 100;
}];
SKScene *scene = [[SKScene alloc] initWithSize:size];
scene.scaleMode = SKSceneScaleModeAspectFill;
scene.backgroundColor = [UIColor whiteColor];
[scene addChild:placeHolder];
return scene;
