我正在使用Cocos2D 0.99.5。我有一個CCParallaxNode,並添加了背景精靈。出於某種原因,直到我開始我的地圖開始移動一點時,它們纔會顯示。與球員的運動慢慢滾動。Cocos2D:CCParallaxNode直到我移動我的地圖時才顯示
我有這個添加到INIT:
winSize = [CCDirector sharedDirector].winSize;
bgMountainsMax = floor(winSize.width/240)+1;
if((int)winSize.width%240 > 0){
bgMountainsBumper = ((int)winSize.width%240)/bgMountainsMax;
}else{
bgMountainsBumper = 0;
}
backgroundNode = [CCParallaxNode node];
[self addChild:backgroundNode z:-1];
CGPoint mountainSpeed = ccp(0.5, 0.5);
bgMountains = [[NSMutableArray alloc] initWithCapacity: bgMountainsMax];
for(int i=0; i<bgMountainsMax; ++i){
mountain = [CCSprite spriteWithFile:@"mountainBG1.png"];
mountain.opacity = 80;
[bgMountains insertObject:mountain atIndex:i];
[backgroundNode addChild:[bgMountains objectAtIndex:i] z:0 parallaxRatio:mountainSpeed positionOffset:ccp((240*i)+(bgMountainsBumper*i),98)];
}
而這個加入到更新:
for (CCSprite *mountainNum in bgMountains) {
if ([backgroundNode convertToWorldSpace:mountainNum.position].x < -(240/2)) {
[backgroundNode incrementOffset:ccp(winSize.width+(240),0) forChild:mountainNum];
}
if ([backgroundNode convertToWorldSpace:mountainNum.position].x > winSize.width+(240/2)) {
[backgroundNode incrementOffset:ccp(-(winSize.width+240),0) forChild:mountainNum];
}
}
