Iphone 使用cocos2d处理CCSprite触摸的最佳实践

Iphone 使用cocos2d处理CCSprite触摸的最佳实践,iphone,ipad,cocos2d-iphone,Iphone,Ipad,Cocos2d Iphone,大家好。我刚开始查看cocos2d库。我听说，若你们习惯于用ActionScript编程，那个么这是一个很容易进入的库，我发现很多概念确实是相似的我开始查看示例项目（链接的示例游戏特别有用），我发现触摸处理通常不是在CCSprite中完成的。相反，实例化CCSprite的CCLayer会对触摸事件作出反应，并通过创建的sprite进行迭代，以检测触摸了哪个CCSprite（如果有）我希望ccsprite自己处理是否被触摸过，并打电话通知它被触摸过（如果需要）。在/tests/TouchesT

大家好。我刚开始查看cocos2d库。我听说，若你们习惯于用ActionScript编程，那个么这是一个很容易进入的库，我发现很多概念确实是相似的

我开始查看示例项目（链接的示例游戏特别有用），我发现触摸处理通常不是在CCSprite中完成的。相反，实例化CCSprite的CCLayer会对触摸事件作出反应，并通过创建的sprite进行迭代，以检测触摸了哪个CCSprite（如果有）

我希望ccsprite自己处理是否被触摸过，并打电话通知它被触摸过（如果需要）。在/tests/TouchesTest下找到的

patle

类就是这样做的-它自己处理触摸

所以，我的问题是：这方面的最佳实践是什么？在一个中心位置处理触摸是否更好，并遍历孩子们以查看被触摸的内容？或者每个孩子应该处理自己的触摸事件？还是没关系

我更喜欢每个孩子处理自己的触摸事件，但我希望遵循这方面的最佳实践（如果存在）。谢谢

我认为这是一个偏好的问题，但我喜欢让精灵检测它是否被子类化CCSprite所触动。我在CCSprite子类中创建了一个getter方法，该方法从子类中检索状态变量，然后主程序可以相应地执行操作

下面是我的CCSprite子类“spuButton”的头文件示例：

希望这有助于和快乐的编码

增加勾选方法和解释（针对Stephan的以下问题）：

要检查按钮的状态，我有一个勾号：方法，它基本上触发每一帧并检查我所有按钮的状态

    -(void)tick:(ccTime)dt {

do my button checks here....

}

我通过调用spuButton类中的isPressed或isNotPressed函数来检查按钮的状态

for (spuButton *aButton in _fourButtonsArray) {
     if ([aButton isNotPressed]) continue; //this button is not pressed
     .....otherwise record that it is pressed.....
}

然后我做同样的检查，看看它是否已经发布，并做出相应的回应。我这样做是因为我想能够对多个按键组合做出反应，而且我想在按下按钮时做一些事情，然后在释放按钮时做一些其他事情。我使用CCtouchBegind和ccTouchEnded来更改纹理（精灵图像）并相应地更改状态变量。

只是添加到此线程。Mark还提供了如何实例化SPU按钮的示例，这很有帮助：

您还可以在“修改此示例”中输入普通按钮图像和亮起按钮图像，如下所示：

+ (id)spuButtonWithTexture:(CCTexture2D *)normalTexture lit:(CCTexture2D *)litTexture

然后对以下对象执行相同的操作：

- (id)initWithTexture:(CCTexture2D *)normalTexture lit:(CCTexture2D *)litTexture

在此方法中，可以设置两种纹理：

[self setNormalTexture:normalTexture];
[self setLitTexture:litTexture];

这是我的解决方案，基于CCSprite，希望对某些人有用

这是控制对象（如播放器或其他东西）的协议：

@class AGSensitiveButton；

@必需的
-（无效）SensitiveButton按下：（AGSensitiveButton*）S按钮；
-（void）sensitiveButton上键：（AGSensitiveButton*）S按钮；
