iPhone - cocos2d - 动画和C ++类 [英] iPhone - cocos2d - Animations and C++ class

问题描述

我想为我的游戏添加动画（iPhone应用程序，使用cocos2d）。

I'm trying to add animations to my game (iPhone app, using cocos2d).

游戏是用C ++编写的，现在我想运行它在iPhone上，所以大多数类都是在c ++。

The game was written in C++, and now I want to run it on iPhone, so most of the classes are in c++.

事情看起来像。
我在init函数中创建CCSprite，CCAction在obj-c类中，然后在sprite上运行CCAction。
和动画是工作。

The thing looks like that. I'm creating CCSprite,CCAction in obj-c class in init function, and then run CCAction on sprite. And animation is working.

但我想把这个CCSprite和CCAction变量在我的C ++类。
我在init类中创建* CCSprite，并将这个指针发送到c ++类。然后，我创建CCAction并在精灵上运行它。

But I want to put this CCSprite and CCAction variables in my C++ class. I create *CCSprite in init class and send this pointer to the c++ class. Then, I create CCAction and run it on the sprite.

然后，当我的init函数（obj-c类）do：

And after that, when in my init function (obj-c class) do:

return self;

那么应用程序正在运行，运行和运行，没有任何反应。我在控制台中只收到此讯息：

then the app is running, running and running and nothing happens. I receive only this message in console:

* 声明失败 - [CCSprite setTexture：]， /Michal/..../libs/cocos2d/CCSprite.m:898
终止响应SpringBoard的终止。

* Assertion failure in -[CCSprite setTexture:], /Users/Michal/..../libs/cocos2d/CCSprite.m:898 Terminating in response to SpringBoard's termination.

我不知道下一步我应该做什么...
是否可以成功地保持CCSprite / Action等在C ++类中？

I dont know what should I do next... Is it possible to keep CCSprite/Action etc. in C++ class succesfully?

推荐答案

在尝试使用之前，请确保您已正确初始化纹理，如下所示：

Make sure you have properly initialized the texture before you try to use it like this:

CCTexture2D *redButtonNormal = [[CCTextureCache sharedTextureCache] addImage:@"RedButtonNormal.png"];

/ p>

then initalize the sprite (or sprite subclass - in this example spuButton is a subclass of CCSprite) :

spuButton *redButton = [spuButton spuButtonWithTexture:redButtonNormal];

注意：因为它是一个子类，我必须像这样设置init方法如果你子类化CCSprite）：

Note: since it is a subclass i had to setup the init methods for it like this (You must do this if you subclass CCSprite):

+ (id)spuButtonWithTexture:(CCTexture2D *)normalTexture
{
    return [[[self alloc] initWithTexture:normalTexture] autorelease];
}

- (id)initWithTexture:(CCTexture2D *)aTexture
{
    if ((self = [super initWithTexture:aTexture]) ) {

        state = kButtonStateNotPressed;
    }

    return self;
}
