Question

学生在做AS3，我使用FlashDevelop，我想跟随并使用本教程来帮助我创建塔防游戏：http://www.flashgametuts.com/tutorials/as3/how-to-create-a-tower-defense-game-in-as3-part-1/

我已经开始了一个新项目＆gt; ActionScript 3＆gt; ActionScript 3 Project和我所拥有的是Main.as，其中包含：

package 
{
import flash.display.Sprite;
import flash.events.Event;

/**
 * ...
 * @author Duncan John Bunting
 */
public class Main extends Sprite 
{

    public function Main():void 
    {
        if (stage) init();
        else addEventListener(Event.ADDED_TO_STAGE, init);
    }

    private function init(e:Event = null):void 
    {
        removeEventListener(Event.ADDED_TO_STAGE, init);
        // entry point
    }

}
}

它提到将文件保存到source.fla文件所在的位置（我没有这个），就在第3块代码之前，它说＆＃34;现在，我们必须返回到主.fla文件。创建一个新图层以放置操作，并添加以下代码：＆＃34;

我如何在FlashDevelop中执行此操作，因为我没有source.fla？或者在FlashDevelop中是不可能的？

如果无法实现，有人可以指导我使用ActionScript3在FlashDevelop中创建游戏的教程。

感谢。

是的，在FlashDevelop中，您无法访问.fla，但您仍然可以将时间轴代码移植到FlashDevelop中。为此，请将函数外部的所有var X:Y语句放在行public function Main()之上，而不管它们出现在何处。然后，将所有函数放在init()函数声明的结尾之下。任何其他代码都应放入init()。在您的情况下，该文件应如下所示：

package 
{
import flash.display.Sprite;
import flash.events.Event;

/**
 * ...
 * @author Duncan John Bunting
 */
public class Main extends Sprite 
{

    //setting vars to step in for turns and special blocks
    var S:String = 'START';
    var F:String = 'FINISH';
    var U:String = 'UP';
    var R:String = 'RIGHT';
    var D:String = 'DOWN';
    var L:String = 'LEFT';

    var startDir:String;//the direction the enemies go when they enter
    var finDir:String;//the direction the enemies go when they exit
    var startCoord:int;//the coordinates of the beginning of the road
    var lvlArray:Array = new Array();//this array will hold the formatting of the roads

    //the names of these variables explain what they do
    var currentLvl:int = 1;
    var gameOver:Boolean = false;

    var roadHolder:Sprite = new Sprite();//create an object that will hold all parts of the road
    public function Main():void 
    {
        if (stage) init();
        else addEventListener(Event.ADDED_TO_STAGE, init);
    }

    private function init(e:Event = null):void 
    {
        removeEventListener(Event.ADDED_TO_STAGE, init);
        // entry point
        // stop(); MovieClip functions are not supported for Main
        lvlArray = [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
        0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
        0,0,0,0,R,1,1,D,0,0,R,1,1,D,0,0,R,1,1,D,0,0,
        0,0,0,0,1,0,0,1,0,0,1,0,0,1,0,0,1,0,0,1,0,0,
        0,0,0,0,1,0,0,1,0,0,1,0,0,1,0,0,1,0,0,1,0,0,

        0,1,0,0,1,0,0,1,0,0,1,0,0,1,0,0,1,0,0,0,0,0,
        0,R,1,1,U,0,0,R,1,1,U,0,0,R,1,1,U,0,0,0,0,0,
        0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
        0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
        0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
        ];
        addChild(roadHolder);//add it to the stage
        //run these functions at the start
        makeRoad();
        startGame();
    }

    function makeRoad():void{
var row:int = 0;//the current row we're working on
var block;//this will act as the block that we're placing down
for(var i:int=0;i<lvlArray.length;i++){//creating a loop that'll go through the level array
    if(lvlArray[i] == 0){//if the current index is set to 0
        block = new EmptyBlock();//create a gray empty block
        block.graphics.beginFill(0x333333);
        block.graphics.drawRect(0,0,25,25);
        block.graphics.endFill();
        addChild(block);
        //and set the coordinates to be relative to the place in the array
        block.x= (i-row*22)*25;
        block.y = row*25;
    } else if(lvlArray[i] == 1){//if there is supposed to be a row
        //just add a box that will be a darker color and won't have any actions
        block = new Shape();
        block.graphics.beginFill(0x111111);
        block.graphics.drawRect(0,0,25,25);
        block.graphics.endFill();
        block.x= (i-row*22)*25;
        block.y = row*25;
        roadHolder.addChild(block);//add it to the roadHolder
    } else if(lvlArray[i] is String){//if it's a string, meaning a special block
        //then create a special block
        block = new DirectBlock(lvlArray[i],(i-row*22)*25,row*25);
        addChild(block);
    }
    for(var c:int = 1;c<=16;c++){
        if(i == c*22-1){
            //if 22 columns have gone by, then we move onto the next row
            row++;
        }
    }
}
}
function startGame():void{//we'll run this function every time a new level begins
//right now we don't have any code
}
}
}

当你被告知在你的.fla中画一些东西并为它指定名字时，会遇到更难的部分。这仍然可以移植到FD中，但是如果没有绘图，则必须使用扩展Sprite（如果已分层）的类将所有绘制例程编码到FD中，或者Shape（如果不是），并使用graphics属性用于绘制简单的基元。请注意，您无法在FD中直接设置锚点，因此您的坐标应与预设锚点（0,0）对齐。
