我有一系列我想玩的SKActions,但是他们打得不好。眼睛只关闭,再也不会打开。我不知道为什么会这样,但也许你这样做!感谢帮助,谢谢。

-(void)blink {

    SKAction *delay = [SKAction waitForDuration:3];
    SKAction *blinkEye = [SKAction resizeToHeight:1 duration:.2];
    SKAction *delay2 = [SKAction waitForDuration:.5];
    SKAction *openEye = [SKAction resizeToHeight:3 duration:.2];

    SKAction *group1 = [SKAction group:@[delay,blinkEye]];
    SKAction *group2 = [SKAction group:@[delay2,openEye]];

    SKAction *all = [SKAction sequence:@[group1,group2]];

    SKAction *repeat = [SKAction repeatActionForever:all];

    [self runAction:repeat];

}

在MyScene.m中

-(void)update:(CFTimeInterval)currentTime {
 /* Called before each frame is rendered */
    Player *player = (Player *)[self childNodeWithName:@"player"];
    Player *lefteye = (Player *)[player childNodeWithName:@"leye"];
    Player *righteye = (Player *)[player childNodeWithName:@"reye"];
    [lefteye blink];
    [righteye blink];

}

不需要分组,导致问题。

SKAction *delay = [SKAction waitForDuration:3];
SKAction *blinkEye = [SKAction resizeToHeight:1 duration:.2];
SKAction *delay2 = [SKAction waitForDuration:.5];
SKAction *openEye = [SKAction resizeToHeight:3 duration:.2];

SKAction *all = [SKAction sequence:@[delay,blinkEye, delay2,openEye]]];

让每一帧更新都眨眼间无法正常工作。此功能每秒最多调用60次。

而是在创建眼睛对象时这样做:

SKAction *delay = [SKAction waitForDuration:3];
SKAction *blinkEye = [SKAction resizeToHeight:1 duration:.2];
SKAction *delay2 = [SKAction waitForDuration:.5];
SKAction *openEye = [SKAction resizeToHeight:3 duration:.2];

SKAction *all = [SKAction sequence:@[delay,blinkEye, delay2,openEye]]];

//create the lefteye object
lefteye = [[Eye alloc] init...]; 
//create the righteye object
righteye = [[Eye alloc] init...];
[lefteye repeatActionForever:all];
