如何更改cocos2d精灵中的图像从数组？ [英] How to change the image in a cocos2d sprite from an array?

问题描述

我正在尝试更改来自数组的sprite正在显示的图像。这里是我使用的代码：

 （（Sprite *）[enemiesArray objectAtIndex：index]）image = baseImage; 
  

我收到错误讯息：

 错误：在结构或联合体中请求成员'image'
  

我做错了什么？

感谢您阅读。

解决方案

我不认为这是做到这一点的方法。
而不是你应该调用一个init方法：

- （id）initWithCGImage：（CGImageRef）image;

- （id）initWithTexture：（Texture2D *）tex;

- （id）initWithFile：（NSString *）imageFile;

在我的游戏中，我做了不同的，我有一个类为我的对象称为'Zed'，我也存储在一个数组。它有一个精灵作为一个字段，如果我想改变图像，我交换整个精灵，并确保我隐藏旧的，显示新的。

I'm trying to change the image that a sprite from an array is displaying. Here is the code I'm using:

((Sprite *)[enemiesArray objectAtIndex:index]).image = baseImage;

I get the error message:

error: request for member 'image' in something not a structure or union

What am I doing wrong?

Thanks for reading.

解决方案

I don't think that this is the way to do this. Rather than that you should call one of the init methods:

- (id) initWithCGImage:(CGImageRef)image;

- (id) initWithTexture:(Texture2D*) tex;

- (id) initWithFile:(NSString *) imageFile;

In my game i do this differently, i have a class for my object called 'Zed' which i also store in an array. It has a sprite as a field and if i want to change the image i swap the whole sprite and make sure i hide the old and show the new one.
