有没有办法在SpriteKit中创建一个渐变填充框？我已经尝试用它填充一个形状节点,但它注意到只有纯色与skshapenode一起使用.

Sequelize图书馆的新手.根据我的理解,'id'是由sequelize自动创建的(这就是我在数据库中看到的).但是当我去'创建'一个对象时,它会抛出这个错误:

    { [SequelizeUniqueConstraintError: Validation error]
  name: 'SequelizeUniqueConstraintError',
  message: 'Validation error',
  errors: 
   [ { message: 'id must be unique',
       type: 'unique violation',
       path: 'id',
       value: '1' } ],
  fields: { id: '1' } }

违规代码:

  db.Account.create({
    email: req.body.email,
    password: req.body.password,
    allowEmail: req.body.allowEmail,
    provider: 'local',
    role: 'user'
  })

通知ID未在任何地方指定,也未在我的模型定义中指定.如果我在postgres admin中运行它,它生成的查询运行正常:

INSERT INTO "Accounts" ("id","email","role","verifyCode","provider","cheaterScore","isBanned","allowEmail","updatedAt","createdAt") VALUES (DEFAULT,'cat69232@gmail.com','user','','local',0,false,false,'2016-01-27 04:31:54.350 +00:00','2016-01-27 04:31:54.350 +00:00') RETURNING *;

对于我在这里可能缺少的任何想法？

Objective C库中有一些C样式函数我绑定到我需要在我的应用程序中访问的函数.是否可以以任何方式将这些添加到绑定中,以便我可以在我的C#应用​​程序中访问它们？

来自Cocos2d的例子:

void ccGLActiveTexture( GLenum textureEnum )
{
#if CC_ENABLE_GL_STATE_CACHE
    NSCAssert1( (textureEnum - GL_TEXTURE0) < kCCMaxActiveTexture, @"cocos2d ERROR: Increase kCCMaxActiveTexture to %d!", (textureEnum-GL_TEXTURE0) );
    if( (textureEnum - GL_TEXTURE0) != _ccCurrentActiveTexture ) {
        _ccCurrentActiveTexture = (textureEnum - GL_TEXTURE0);
        glActiveTexture( textureEnum );
    }
#else
    glActiveTexture( textureEnum );
#endif
}

链接到我正在尝试导入的函数的标题:http: //www.cocos2d-iphone.org/api-ref/2.0.0/cc_g_l_state_cache_8h_source.html

我在Extras.cs中试过这个

public partial class CCGLProgram {
[DllImport("__Internal")]
    public static extern void ccGLUseProgram( uint program );

    public static void CCGLUseProgram(uint test)
    {
        ccGLUseProgram(test);
    }
}

不幸的是,我得到一个入口点未找到错误.我想我的第一个想法可能是功能被破坏但是我认为,因为'extern C'是不应该发生的？谁能帮我？

我的场景加载可能需要一段时间,我希望能够显示加载动画,但是,一切都锁定了.有没有办法加载下一个场景异步并在准备好后获得回调？

我真的陷入了一个Core Data我似乎无法解决的错误:

Can't migrate SQLite store: Error Domain=NSCocoaErrorDomain Code=134110 The operation couldn’t be completed. (Cocoa error 134110.) UserInfo=0xab4b630 {NSUnderlyingError=0xab4b2e0 The operation couldn’t be completed. (Cocoa error 516.), reason=Can't copy source store to destination store path

我找不到有关此错误的任何资源...

它是一个非常简单的迁移,只有一个模型"User"具有name属性和created_by属性,对于我的测试我没有改变任何东西,两个模型是相同的.我只想让它发挥作用.有任何想法吗？

继承人我的问题我正在尝试为iphone的cocos2d中的动作序列创建一个回调函数,但我一直收到错误的访问错误.

在这里,我创建了我的回电

id myCallFunc = [CCCallFuncND actionWithTarget:self.delegate selector:@selector(playerAttack:data:) data:(__bridge void *)([[PlayerAttackPacket alloc] initWithPlayer:@"" attackChoice: [NSNumber numberWithInt: item.tag]]) ]; // to call our method

这里是回调函数,在编译数据时编译器说错误访问.

-(void) playerAttack:(id)sender data:(void *)data
{
    PlayerAttackPacket* packet = (__bridge PlayerAttackPacket*)data;
    BattleModel *model = [BattleModel sharedInstance];
    int choice = packet.attackChoice.intValue;
    NSString * players = packet.player;
}

播放器包:

@interface PlayerAttackPacket : NSObject {
    NSString * player;
    NSNumber * attackChoice;
}

@property (nonatomic, retain) NSString * player;
@property (nonatomic, retain) NSNumber * attackChoice;
-(id) initWithPlayer: (NSString*)_player attackChoice: (NSNumber*)choice;
@end …
