cocos2d-x 創建幀動畫

看到好多人問如何用cocos2d-x創建幀動畫,其實用cocos2d-x很容易創建幀動畫。我就寫一遍吧。

1. void MyClass::initMyAnim()
2. {
3. /**
4. //可以在程序載入的時候預加載這些動畫資源，然後在cache中讀取
5. CCSpriteFrameCache* cache = CCSpriteFrameCache::sharedSpriteFrameCache();
6. cache->addSpriteFramesWithFile("run.plist", "run.png");
7. */
8. CCSpriteFrameCache* cache = CCSpriteFrameCache::sharedSpriteFrameCache();
9. CCMutableArray<CCSpriteFrame*>* animFrames = new CCMutableArray<CCSpriteFrame*>(12);
11. char str[64] = {0};
12. for(int i = 1; i <=12; i++)
13. {
14. sprintf(str, "run%04d.png", i);
15. CCSpriteFrame* frame = cache->spriteFrameByName( str );
16. animFrames->addObject(frame);
17. }
19. CCAnimation* animation = CCAnimation::animationWithFrames(animFrames,0.4f);
20. CCActionInterval* action=CCAnimate::actionWithAnimation(animation,true);
21. CCFiniteTimeAction *myRun= CCSequence::actions(action,CCCallFunc::actionWithTarget(this,callfunc_selector(MyClass::callBackRun)),NULL);
22. myRun->retain();
23. animFrames->release();
24. }

CCCallFunc用來做動畫回調用，沒有回調的話，就不用了。myRun->retain()後記得release掉。

OK，是不是很簡單。記錄一筆。
