如何将一个矢量数据转换为ActionScript 3.0中的另一个矢量数据

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

有一个更方便的方法来做到这一点。

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

注意，当您使用“矢量。<的iGame>（shootgames）”你是不是做一个类型转换，而是要创建一个新的Vector实例，并与“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
