Cocos2D无限背景图片

Question

我很好奇如何在cocos2d中创建无限背景.例如,假设我正在构建一个从左到右运行的应用程序的应用程序,我希望他无限运行.那么在那种情况下,我必须拥有无尽的背景,这样男人才能继续奔跑.我一直在搜索这个问题,并没有找到任何实际可行的东西.

任何类型的建议,答案和提示都非常感谢.

谢谢

试试这个:

 #define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
 #define MM_BG_SPEED_DUR       ( IS_IPAD ? (6.0f) : (2.0f) )



-(void)onEnter
{
    [super onEnter];
    [self initBackground];

    [self schedule: @selector(tick:)];
}


-(void)initBackground
{
   NSString *tex = @"BG/Background.png";//[self getThemeBG];

    mBG1 = [CCSprite spriteWithFile:tex];
    mBG1.position = ccp(s.width*0.5f,s.height*0.5f);
    [self addChild:mBG1 z:LAYER_BACKGROUND];

    mBG2 = [CCSprite spriteWithFile:tex];
    mBG2.position = ccp(s.width+s.width*0.5f,s.height*0.5f);

    mBG2.flipX = true;
    [self addChild:mBG2 z:LAYER_BACKGROUND];

}


-(void)scrollBackground:(ccTime)dt
{
    CGSize s = [[CCDirector sharedDirector] winSize];

    CGPoint pos1 = mBG1.position;
    CGPoint pos2 = mBG2.position;

    pos1.x -= MM_BG_SPEED_DUR;
    pos2.x -= MM_BG_SPEED_DUR;


    if(pos1.x <=-(s.width*0.5f) )
    {
        pos1.x = pos2.x + s.width;
    }

    if(pos2.x <=-(s.width*0.5f) )
    {
        pos2.x = pos1.x + s.width;
    }

    mBG1.position = pos1;
    mBG2.position = pos2;

}

-(void)tick:(ccTime)dt
{
    [self scrollBackground:dt];
}
