我安排了一个名为imageblink的方法每5秒调用一次。该方法将使我的精灵从数组中闪烁(出现和消失)。但在几次呼叫后(大约10次或更多),精灵停止闪烁。但是,NSLog的"blink"输出仍然每隔5s出现一次。我在iphone模拟器和ipod上都有这个问题。谢谢你的帮助。
如果一个对象已经在运行闪烁序列,而您在运行另一个对象,这可能会干扰屏幕上正在发生的事情。我建议在运行新序列之前添加stopAllActions。
我注意到的另一件事是你运行一个CCFadeOut动作。请记住,在这个动作完成后,精灵的不透明度将为0,CCBlink改变了可见属性,但不影响不透明度。这意味着你应该确保精灵在开始序列之前处于最大不透明度:
[object stopAllActions];
object.opacity = 255;
[object runAction: [CCSequence actions:[CCBlink actionWithDuration:2 blinks:1],[CCFadeOut actionWithDuration:2], nil]];
