如何在Actionscript 3.0中将一个矢量数据转换为另一个矢量数据

Question

Class ShootGame implements IGame
{

}

//ShootGame Vector 

 var shootGames:Vector.<ShootGame> = new Vector.<ShootGame>();
for(i=0;i<20;i++)
{
   shootGames.push(new ShootGame());
}



var igames:Vector.<IGame> = //What is the Simplest method to convert ShootGame to IGame Vector

//I am doing like

igames = new Vector.<IGame>();

for(i=0;i < shootGames.length;i++)
{

igames.push(shootGames[i]);

}

Answer 1

有一种更方便的方法。

var igames:Vector.<IGame> = Vector.<IGame>(shootGames);

请注意，当您使用“Vector。＆lt; IGame＆gt;（shootgames）”时，您没有进行类型转换，而是创建一个新的Vector实例并使用“shootGames”Vector的内容填充它。

示例代码：

var shootGames:Vector.<ShootGame> = new Vector.<ShootGame>();
for (var i:int = 0; i < 20; i++) {
    shootGames.push(new ShootGame());
}

var igames:Vector.<IGame> = Vector.<IGame>(shootGames);

trace("shootGames.length", shootGames.length); //20
trace("igames.length", igames.length); //20
