ios - 在切换到新场景之前，Sprite 套件无法运行 Action

Question

操作不在此代码中运行:

 SKAction *moveLeft = [SKAction moveToX:(-800) duration:0.6];
 SKAction *moveRight = [SKAction moveToX:(800) duration:0.6];
 [_labelLogo runAction:moveLeft];
 [_labelPlay runAction:moveRight];  

 NewYork *start = [[NewYork alloc] initWithSize:self.size];
 SKTransition *reveal = [SKTransition fadeWithColor:[UIColor clearColor] duration:2];
 reveal.pausesIncomingScene = NO;

 [self.scene.view presentScene: start transition: reveal];

如果我评论 NewYork switching 它们会起作用。

Answer 1

action *moveLeft/*moveRight 的问题，因为立即开始转换到 NewYork 场景，所以你应该等待 *moveLeft/*moveRight 完成，如下所示:

 SKAction *moveLeft = [SKAction moveToX:(-800) duration:0.6];
 SKAction *moveRight = [SKAction moveToX:(800) duration:0.6];
 [_labelLogo runAction:moveLeft];

 [_labelPlay runAction:moveRight completion:^{

    NewYork *start = [[NewYork alloc] initWithSize:self.size];
    SKTransition *reveal = [SKTransition fadeWithColor:[UIColor clearColor] duration:2];
    reveal.pausesIncomingScene = NO;

    [self.view presentScene:start transition:reveal];
 }];
