ios - 背景色Flash Sprite套件

我正在尝试使flashBackground的背景闪烁白色。我如何使用Sprite Kit做到这一点。我创建了SKSpriteNode，在其下我想从clearcolor闪烁到whitecolor到clearcolor。

flashBackground = [SKSpriteNode spriteNodeWithColor:[SKColor clearColor] size:
                       CGSizeMake(self.size.width, self.size.height)];

[self addChild:flashBackground];

最佳答案

SKAction *wait0 = [SKAction waitForDuration:1.0]; // 1 sec delay

SKAction *block0 = [SKAction runBlock:^{
    flashBackground.color = [SKColor whiteColor];
}];

SKAction *block1 = [SKAction runBlock:^{
    flashBackground.color = [SKColor clearColor];
}];

[flashBackground runAction:[SKAction repeatActionForever:[SKAction sequence:@[wait0, block0, wait0, block1]]]];

或仅将最后一行更改为:

[flashBackground runAction:[SKAction sequence:@[wait0, block0, wait0, block1]]];
