编辑:在第一个回答之后我更多地了解了stackoverflow并将问题重新解释为“我怎么才能只使用高清文件?”并找到了这个:How do I stop Cocos2D from requiring standard definition resources (SD images)?我现在将尝试提出的解决方案如果它有效,我将保留编辑过的标题并删除可能会产生误导的初始问题。
有一段时间我正在尝试学习Cocos2d并使用cookbook和learn cocos2d之类的书籍。这些都是一个很好的开始,但有时我会遇到像我今天要解释的问题。
我在第66页的书1中开始修改使用CCParallaxNode的示例。我的目标是添加以下大小的四个层:960像素高和1280像素,在iOS 5.0的iPhone模拟器上运行使用Cocos2d 1.01 rc库。
我使用安装的模板创建了一个新项目,并修改了HelloWorldLayer.m类,如下所示:
// Import the interfaces
#import "HelloWorldLayer.h"
// HelloWorldLayer implementation
@implementation HelloWorldLayer
+(CCScene *) scene
{
// 'scene' is an autorelease object.
CCScene *scene = [CCScene node];
// 'layer' is an autorelease object.
HelloWorldLayer *layer = [HelloWorldLayer node];
// add layer as a child to scene
[scene addChild: layer];
// return the scene
return scene;
}
// on "init" you need to initialize your instance
-(id) init
{
// always call "super" init
// Apple recommends to re-assign "self" with the "super" return value
if( (self=[super init])) {
CCSprite* parallaxLayer01 = [CCSprite spriteWithFile:@"0-hd-red.png"];
CCSprite* parallaxLayer02 = [CCSprite spriteWithFile:@"0-hd-red.png"];
CCSprite* parallaxLayer03 = [CCSprite spriteWithFile:@"0-hd-red.png"];
CCSprite* parallaxLayer04 = [CCSprite spriteWithFile:@"0-hd-red.png"];
/**
CCSprite* parallaxLayer01 = [CCSprite spriteWithFile:@"0-hd.png"];
CCSprite* parallaxLayer02 = [CCSprite spriteWithFile:@"1-hd.png"];
CCSprite* parallaxLayer03 = [CCSprite spriteWithFile:@"2-hd.png"];
CCSprite* parallaxLayer04 = [CCSprite spriteWithFile:@"3-hd.png"];
**/
/**
CCSprite* parallaxLayer01 = [CCSprite spriteWithFile:@"2-hd.png"];
CCSprite* parallaxLayer02 = [CCSprite spriteWithFile:@"2-hd.png"];
CCSprite* parallaxLayer03 = [CCSprite spriteWithFile:@"2-hd.png"];
CCSprite* parallaxLayer04 = [CCSprite spriteWithFile:@"2-hd.png"];
**/
/**
CCSprite* parallaxLayer01 = [CCSprite spriteWithFile:@"bar.png"];
CCSprite* parallaxLayer02 = [CCSprite spriteWithFile:@"bar.png"];
CCSprite* parallaxLayer03 = [CCSprite spriteWithFile:@"bar.png"];
CCSprite* parallaxLayer04 = [CCSprite spriteWithFile:@"bar.png"];
**/
/**
CCSprite* parallaxLayer01 = [CCSprite spriteWithFile:@"bar-hd.png"];
CCSprite* parallaxLayer02 = [CCSprite spriteWithFile:@"bar-hd.png"];
CCSprite* parallaxLayer03 = [CCSprite spriteWithFile:@"bar-hd.png"];
CCSprite* parallaxLayer04 = [CCSprite spriteWithFile:@"bar-hd.png"];
**/
//Create a parallax node and add all four sprites
CCParallaxNode* parallaxNode = [CCParallaxNode node];
[parallaxNode setPosition:ccp(0,0)];
[parallaxNode addChild:parallaxLayer01 z:1 parallaxRatio:ccp(0, 0) positionOffset:ccp(0,0)];
[parallaxNode addChild:parallaxLayer02 z:2 parallaxRatio:ccp(1, 0) positionOffset:ccp(0,0)];
[parallaxNode addChild:parallaxLayer03 z:3 parallaxRatio:ccp(2, 0) positionOffset:ccp(0,0)];
[parallaxNode addChild:parallaxLayer04 z:4 parallaxRatio:ccp(3, 0) positionOffset:ccp(0,0)];
[self addChild:parallaxNode z:0 tag:1];
//Move the node to the left then the right
//This creates the effect that we are moving to the right then the left
CCMoveBy* moveRight = [CCMoveBy actionWithDuration:5.0f position:ccp(-80, 0)];
CCMoveBy* moveLeft = [CCMoveBy actionWithDuration:2.5f position:ccp(80, 0)];
CCSequence* sequence = [CCSequence actions:moveRight, moveLeft, nil];
CCRepeatForever* repeat = [CCRepeatForever actionWithAction:sequence];
[parallaxNode runAction:repeat];
}
return self;
}
// on "dealloc" you need to release all your retained objects
- (void) dealloc
{
// in case you have something to dealloc, do it in this method
// in this particular example nothing needs to be released.
// cocos2d will automatically release all the children (Label)
// don't forget to call "super dealloc"
[super dealloc];
}
@end
我确实尝试使用4运行代码,这是一个使用GIMP创建的Alpha通道的PNG图像。它最初工作,现在不再。我不知道我做了什么搞砸了。
奇怪的是,它与图像5一起工作。
我已经检查过UIImage规范有限制,建议使用1024 x 1024图像。所以我做了并重新调整了图像6并创建了图像 3,它在UIImage指定的限制范围内但不起作用。
对于不工作,我的意思是代码崩溃时出现以下错误消息:

我认为图像尺寸不是我以前能够运行的问题,但事实上它适用于图像5而不适用于其他图像6这表明我是与我如何使用GIMP创建PNG文件有关...
任何胶水?我附上我正在使用的GIMP设置4的屏幕截图(不是英文,将在下面提供翻译):
厚实: 将颜色保存为背景,保存分辨率,保存创建日期,保存注释并节省透明点的颜色值。
没有厚: Interlacment(Adam7),保存伽玛,保存图层移动
答案 0 :(得分:1)
要使用视网膜图像,必须在项目中包含-hd和非hd文件。它们不一定是合适的尺寸,但它们必须都存在。
因此,如果您要使用名为0-red.png
的文件,则必须包含0-red.png
和0-red-hd.png
。另外,请注意让-hd
位于文件名的末尾。
