Question

我无法弄清楚这一点。我有一个游戏，当玩家从天而降时，他们必须抓住浆果。当玩家错过一个时，我希望屏幕闪烁红色，浆果停止下降，游戏暂停3秒然后恢复。

@interface SpriteMyScene : SKScene{
    SKAction *sceneUnPaused;
    SKAction *scenePaused;   
}

暂停游戏的两种方法。

-(SKAction*)unpaused {
    sceneUnPaused = [SKAction runBlock:^{
        self.scene.view.paused = NO;
    }];
    return sceneUnPaused;}

    -(SKAction*)paused{
               scenePaused = [SKAction runBlock:^{
        self.scene.view.paused = YES;
    }];
    return scenePaused;
}

创造浆果及其行为的方法。

- (void)addBerry {
...
...
// Create the actions
//For each individual berry
SKAction * actionMove = ...
SKAction * gameWon = ...
SKAction * actionMoveDone = ...

SKAction *wait3Seconds = [SKAction waitForDuration:3];
SKAction * loseAction = [SKAction runBlock:^{
    [self subtractLives];
    NSLog(@"Lost a life");
    [self vibrate];
    [self runAction:scenePaused];
    [self runAction:wait3Seconds];
    [berry removeFromParent];
    [self runAction:sceneUnPaused];

    if (_playerLives == 0){
        [[SoundManager sharedManager] stopMusic];
        SKTransition *reveal = [SKTransition fadeWithDuration:1.0];
        SKScene * gameOverScene = [[GameOverScene alloc] initWithSize:self.size andScore:_berriesKilled];
        [self.view presentScene:gameOverScene transition: reveal];}}];

SKAction *berrie = [SKAction runBlock:^{
        [berry runAction:actionMove];}];

[berry runAction:[SKAction sequence:@[berrie, gameWon, actionMove,  loseAction, actionMoveDone]]];

}

我不知道你们是否有必要帮助我弄清楚它为什么不起作用，但这里有更新方法决定何时我会产生浆果。

- (void)updateWithTimeSinceLastUpdate:(CFTimeInterval)timeSinceLast {

self.lastSpawnTimeInterval += timeSinceLast;

if (self.lastSpawnTimeInterval > [self determineAmountOfBerries]) {
self.lastSpawnTimeInterval = 0;
[self addBerry];

}

}

当玩家错过浆果时，只需这样做：

[self.scene.view setPaused:YES];

启动NSTimer，在3秒后执行以下操作：

[berry removeFromParent];
[self.scene.view setPaused:NO];
