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]);

}

有一种更方便的方法可以做到这一点。

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

请注意，当您使用“Vector.< IGame >(shootgames)”时，您并不是在进行类型转换，而是创建一个新的 Vector 实例并用“shootGames”矢量的内容填充它。

有关更多详细信息，请访问此处。

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

There is a more convenient way to do that.

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

Notice that when you use "Vector.< IGame >(shootgames)" you are not making a typecast, instead you are creating a new Vector instance and populating it with the content of the "shootGames" Vector.

For more detailed information, go here.

Sample code:

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
