Objective-C [Xcode] CCAnimation不起作用，cocos2d

Question

我在播放器類中聲明了兩個動畫，然后我想從另一個類中運行，但是我不能在這里輸入我的代碼（如果您在此處看不到它，則位於pastebin上： http : //pastebin.com/iy0eFMWL ） ：player.h

    @interface Player : CCSprite {
    CCAnimate *animationOllie;
    CCRepeatForever *repeatNormal;
    }

player.m：

    @implementation Player

    -(id)initWithFile:(NSString *)filename
    {
if (self = [super initWithFile:filename]) {
    self.velocity = ccp(0.0, 0.0);


    CCAnimation *ollie = [CCAnimation animation];
    [ollie setDelayPerUnit:0.05f];
    [ollie addSpriteFrameWithFilename:@"ollie1.png"];
    [ollie addSpriteFrameWithFilename:@"ollie2.png"];

    animationOllie = [CCAnimate actionWithAnimation:ollie];


    CCAnimation *normal = [CCAnimation animation];
    [normal setDelayPerUnit:0.05f];
    [normal addSpriteFrameWithFilename:@"normal1.png"];
    [normal addSpriteFrameWithFilename:@"normal2.png"];
    CCAnimate *animationNormal = [CCAnimate actionWithAnimation:normal];

    repeatNormal = [CCRepeatForever actionWithAction:animationNormal];

    [self runAction:repeatNormal];

        }
        return self;
    }
    -(void)animateThePlayer {
        [self stopAction:repeatNormal];
        [self runAction:animationOllie];
    }

在GameScene類中：GameScene.h：

    @interface GamePlayLayer : CCLayerColor {
        float yVel;
    }

GameScene.m：

    #import "Player.h"

    @interface GamePlayLayer()
    {
        Player *player;
     }

    @end

    @implementation GamePlayLayer

    -(id) init
    {
        if( (self=[super initWithColor:ccc4(255,255,255,255)] )) {

    player = [[Player alloc] initWithFile:@"normal1.png"];

    [self addChild:player];

    self.isTouchEnabled = YES;

    player.position = ccp(85,70);


    [self schedule:@selector(update:)];

        }
        return self;
    }

    -(void)update:(ccTime)dt {

        if (player.position.y > 70) {
            yVel -= 0.1;
        }
else {
    if (yVel != 5.5) {
        yVel = 0;
        player.position = ccp(player.position.x, 70);
    }
}
player.position = ccp(player.position.x, player.position.y + yVel);

    }


    - (void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    yVel = 5.5;
        [player animateThePlayer];
    }

就是這樣，它構建良好，並且一切正常，但是當我單擊該圖層時它崩潰了，我得到以下消息：

0x1df609b：movl8（％edx），％edi線程1：EXC_BAD_ACCESS（code = 2，address = 0xf

我能做什么？ 提前致謝

第一件事-您嘗試使用自動釋放的對象。 animationOllie將在您的init方法之后釋放。

第二個錯誤是您不能重用動作。 當需要執行操作時，必須重新創建它。
