本文介绍如何使用 Cocos2d-x 游戏引擎进行屏幕渲染并截图保存为图片文件。通过创建渲染纹理并利用游戏层遍历所有子节点的方法完成截图功能。

Size visibleSize = Director::getInstance()->getVisibleSize();
Vec2 origin = Director::getInstance()->getVisibleOrigin();

char data[20] = {"我是中国人"};
String str = chineseDisplay::a(data);

Label* labell = Label::createWithSystemFont(str.getCString(), "宋体", 30);
labell->setPosition(Point(50, 300));
addChild(labell);

RenderTexture* texture = RenderTexture::create(visibleSize.width, visibleSize.height);
texture->begin();

//Scene* s = Director::getInstance()->getRunningScene(); //我这取不到S的值

//s->visit()

this->visit(); //所以用layer遍历所有子节点
texture->end();
if (texture->saveToFile("b.jpg", kCCImageFormatJPEG))
{
CCLOG("Succes");
}

String string = FileUtils::getInstance()->getWritablePath() + "b.png";

CCLOG("%s", string.getCString()); //文件存储路劲
