Cocos2D - 건물 사이에 구멍과 높이를 더하는 것

Question

나는 Canabalt와 유사한 것을 짓고 건물과 건물 (모듈) 사이에 구멍과 높이를 더하려고합니다. (간단한 랜드를 추가 할 수

{ 
    // always call "super" init 
    // Apple recommends to re-assign "self" with the "super" return value

     [self addChild:spriteBatch]; 

     numStripes = 1;

은 건물 사이에 구멍을 추가 : 내가 현재 사용하고 코드를 여기에 http://twitpic.com/4kb5jd

됩니다 : 당신은 어떻게 게임에서 지금 찾고의 스크린 샷을 볼 수 있습니다 INIT 방법에서처럼) 기능 :

...

sprite.position = CGPointMake(((moduleSize * 3) - 1.1f + (rand()%40)), screenSize.height/2); 

...

무작위 간격을 추가합니다 (최대 40 점)
