精灵动画

Question

我正在使用此代码为此精灵设置动画：

_ship = [[GameObject alloc] initWithSpriteFrameName:@"SpaceFlier_sm_1.png" world:_world shapeName:@"SpaceFlier_sm_1" maxHp:10 healthBarType:HealthBarTypeGreen];

     CCSpriteFrameCache * cache =
    [CCSpriteFrameCache sharedSpriteFrameCache];

    CCAnimation *animation = [CCAnimation animation];
    [animation addSpriteFrame:
     [cache spriteFrameByName:@"SpaceFlier_s_2.png"]];
    [animation addSpriteFrame:
     [cache spriteFrameByName:@"SpaceFlier_s_3.png"]];
    [animation addSpriteFrame:
     [cache spriteFrameByName:@"SpaceFlier_s_4.png"]];
    [animation addSpriteFrame:
     [cache spriteFrameByName:@"SpaceFlier_s_5.png"]];
    [animation addSpriteFrame:
     [cache spriteFrameByName:@"SpaceFlier_s_6.png"]];
    [animation addSpriteFrame:
     [cache spriteFrameByName:@"SpaceFlier_s_7.png"]];
    [animation addSpriteFrame:
     [cache spriteFrameByName:@"SpaceFlier_s_8.png"]];
    [animation addSpriteFrame:
     [cache spriteFrameByName:@"SpaceFlier_s_2.png"]];


    animation.delayPerUnit = 0.05;

    [_ship runAction:
     [CCRepeatForever actionWithAction:
      [CCAnimate actionWithAnimation:animation]]];

效果很好。 然后，当我尝试使用此代码为另一个精灵设置动画时，它不起作用。

这样：

if ((self = [super initWithSpriteFrameName:@"dragon.png" world:world shapeName:@"Boss_ship" maxHp:50 healthBarType:HealthBarTypeRed])) {
    _layer = layer;

    CCSpriteFrameCache * cache =
    [CCSpriteFrameCache sharedSpriteFrameCache];

    CCAnimation *animation = [CCAnimation animation];
    [animation addSpriteFrame:
     [cache spriteFrameByName:@"dragon2.png"]];
    [animation addSpriteFrame:
     [cache spriteFrameByName:@"dragon.png"]];



    animation.delayPerUnit = 0.05;

    [self runAction:
     [CCRepeatForever actionWithAction:
      [CCAnimate actionWithAnimation:animation]]];

我只能看到dragon2.png，它不会改变龙，png ......

检查dragon.png是否在您的精灵地图集或捆绑资源中。另外，仔细检查文件名中的大小写与您的字符串完全匹配。
