cocos2dx popScene 使用 Transition小技巧

今天才知道cocos2dx popScene 没有Transition,只能生硬地切换，不能忍...搜索了一下，分享小技巧~

在头文件中增加两个方法：

Scene * getPreviousScene();

void popSceneWithTransition(Scene *trans);

Director.cpp 实现如下：

Scene * Director::getPreviousScene()
{
    ssize_t c = _scenesStack.size();
    if (c <= 1) return NULL;
    return (Scene*)_scenesStack.at(c - 2);
}

void Director::popSceneWithTransition(Scene * trans)
{
     log("popSceneWithTransition+++++++++++++++++++++++++++++++stack size = %zd",_scenesStack.size());
    CCASSERT(_runningScene != NULL,"running scene should not null");
    _scenesStack.popBack();
    ssize_t c = _scenesStack.size();

    if (c == 0) {
        end();
    }
    else {
        _sendCleanupToScene = true;
       _nextScene = trans; // (CCScene*)m_pobScenesStack->objectAtIndex(c - 1);
    }
} 

用法如下:


Scene *preScene = Director::getInstance() -> getPreviousScene();
    TransitionScene *transition = TransitionSlideInL::create(0.3,preScene);Director::getInstance() -> popSceneWithTransition(transition); 欢迎访问我的博客：helkyle.tk
