在Unity引擎中如何生成本地XML數(shù)據(jù)?
第一步:引用C#的命名空間System.Xml
第二步:生成XML文檔(XmlDocument類(lèi))
第三步:生成根元素(XmlElement類(lèi))添加給文檔對(duì)象
第四步:循環(huán)生成子元素添加給父元素
第五步:將?成的XML文檔保存

//獲得Xml保存路徑（放在Assets文件夾下）

//1.生成XML文檔實(shí)例
XmlDocument xmlDoc=new XmlDocument( );
//生成聲明語(yǔ)句

//2.生成根節(jié)點(diǎn)
XmlElement root=xmlDoc.CreateElement("Cube");
//3.生成子節(jié)點(diǎn)
