Question

帮助!!!这个as2代码给了我一个头脑麻木的头痛。有人可以帮助我将其转换为AS3。这是代码：

import flash.filters.GlowFilter;

//Settings
var maxDist:Number = 400;
var accuracy:Number = 1;

//other vars (do not edit)
var dx:Number;
var dy:Number;
var startX:Number;
var startY:Number;
var endX:Number;
var endY:Number;
var realDist:Number;
var rad:Number = Math.PI/180;
var rad2:Number = 180/Math.PI;
map_mc.createEmptyMovieClip("laser_mc", map_mc.getNextHighestDepth());

//Glow Filter 
var glow:GlowFilter = new GlowFilter();
glow.color = 0xFF0000;
glow.alpha = 1;
glow.blurX = 7;
glow.blurY = 7;
glow.quality = 2;
map_mc.laser_mc.filters = new Array(glow);

/**
*
* Mouse Controls
*
*/
//create an object that we'll listen to
mouseListener = new Object();

//on Click, fire the weapon
mouseListener.onMouseDown = function() {
    fireWeapon();
}
//on release, stop weapon firing
mouseListener.onMouseUp = function() {
    stopWeapon();
}
//on mouse move, rotate the player
mouseListener.onMouseMove = function() {
    rotatePlayer();
}
//add listener
Mouse.addListener(mouseListener);


/**
*
* Laser Weapon
*
*/
//fire weapon function - creates an onEnterFrame function to repeat updateLaser() over and over
function fireWeapon():Void 
{
    _root.onEnterFrame = function ():Void {
        updateLaser();
    }
}

//stop weapon function - deletes onEnterFrame and clears laser movieclip
function stopWeapon():Void 
{   
    delete _root.onEnterFrame;
    map_mc.laser_mc/**/.clear();
}

//Update Laser Function
function updateLaser() :Void
{       
    //run a loop 
    for (realDist=0; realDist<maxDist; realDist += accuracy) 
    {       
        //get end X&Y
        endX = map_mc.player_mc._x + Math.cos(map_mc.player_mc._rotation * rad) * realDist;
        endY = map_mc.player_mc._y + Math.sin(map_mc.player_mc._rotation * rad) * realDist;

        //calculate hit test
        if (map_mc.walls_mc.hitTest(endX, endY, true)) {
            break;
        }
    }

    //calculate the tip of the barrel (start X & Y)
    startX = map_mc.player_mc._x + 15 * Math.cos(map_mc.player_mc._rotation * rad);
    startY = map_mc.player_mc._y + 15 * Math.sin(map_mc.player_mc._rotation * rad);

    // Clear it before we draw, so the line doesnt stay there
    map_mc.laser_mc.clear();

    //draw laser
    map_mc.laser_mc.lineStyle(2, 0xFF0000, 75);
    map_mc.laser_mc.moveTo(startX, startY);
    map_mc.laser_mc.lineTo(endX, endY);
}

//rorate player towards mouse function
function rotatePlayer():Void
{
    //get distance between mouse and player
    dx = map_mc._xmouse-map_mc.player_mc._x;
    dy = map_mc._ymouse-map_mc.player_mc._y;

    //calculate rotation of player
    map_mc.player_mc._rotation = Math.atan2(dy, dx)*rad2;
}

这是其中的大部分你现在不应该得到编译错误另外我把它清理干净了你还必须修改你的旋转点player_mc

import flash.filters.GlowFilter;

//Settings
var maxDist:Number = 400;
var accuracy:Number = 1;

//other vars (do not edit)
var dx:Number;
var dy:Number;
var startX:Number;
var startY:Number;
var endX:Number;
var endY:Number;
var realDist:Number;
var rad:Number = Math.PI/180;
var rad2:Number = 180/Math.PI;

var laser_mc:MovieClip = new MovieClip()
map_mc.addChild(laser_mc)

//Glow Filter 
var glow:GlowFilter = new GlowFilter();
glow.color = 0xFF0000;
glow.alpha = 1;
glow.blurX = 7;
glow.blurY = 7;
glow.quality = 2;
laser_mc.filters = new Array(glow);

/**
*
* Mouse Controls
*
*/
stage.addEventListener( MouseEvent.MOUSE_DOWN, fire);
//on Click, fire the weapon
function fire( e:Event ):void {
    stage.addEventListener( Event.ENTER_FRAME , updateLaser)
}

stage.addEventListener( MouseEvent.MOUSE_UP, stopFire);
//on release, stop weapon firing
function stopFire( e:Event ):void {
    laser_mc.graphics.clear();
    stage.removeEventListener( Event.ENTER_FRAME , updateLaser)
}

stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseMoved)
//on mouse move, rotate the player
function mouseMoved( e:Event ):void {
    //get distance between mouse and player
    dx = map_mc.mouseX-map_mc.player_mc.x;
    dy = map_mc.mouseY-map_mc.player_mc.y;

    //calculate rotation of player
    map_mc.player_mc.rotation = Math.atan2(dy, dx)*rad2;
}

//Update Laser Function
function updateLaser( e:Event ):void {
    //run a loop 
    for (realDist=0; realDist<maxDist; realDist += accuracy){       
        //get end X&Y
        endX = map_mc.player_mc.x + Math.cos(map_mc.player_mc.rotation * rad) * realDist;
        endY = map_mc.player_mc.y + Math.sin(map_mc.player_mc.rotation * rad) * realDist;

        //calculate hit test
        if (map_mc.walls_mc.hitTestPoint(endX,endY)) {
            break;
        }
    }

    //calculate the tip of the barrel (start X & Y)
    startX = map_mc.player_mc.x + 15 * Math.cos(map_mc.player_mc.rotation * rad);
    startY = map_mc.player_mc.y + 15 * Math.sin(map_mc.player_mc.rotation * rad);

    //draw laser
    laser_mc.graphics.clear();
    laser_mc.graphics.lineStyle(2, 0xFF0000);
    laser_mc.graphics.moveTo(startX, startY);
    laser_mc.graphics.lineTo(endX, endY);
}

AS3代码的AS2代码有助于转换！
