Sprite Kit失去生命时暂停游戏

Question

我不知道这一点。 我有一个游戏，玩家必须抓住从天上掉下来的浆果。 当玩家错过比赛时，我希望屏幕闪烁红色，浆果停止掉落，让游戏暂停3秒钟，然后继续播放。

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

暂停游戏的2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;
}

创建浆果及其动作的方法。

- (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]]];

}

我不知道这是否对你们有帮助，以帮助我弄清楚为什么它不起作用，但是这里的更新方法决定了我何时产生浆果。

- (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，只需执行以下操作：

[self.scene.view setPaused:YES];

启动NSTimer，在3秒钟后执行以下操作：

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