Question

嘿伙计们，所以我用这个代码创建了一个迷宫，我想要试试墙壁，但是当我尝试沿着if（mc.hitTestObject（tile））的行时，它什么也没做。我不知道为什么，这是代码：

package  
{

import flash.display.MovieClip;
import flash.events.KeyboardEvent;
import flash.events.Event;
import flash.display.DisplayObject;


public class Main extends MovieClip
{


    private var mc:hero = new hero;
    private var tile:tile1 = new tile1; 
    private var mcSpeed:uint = 5;

    private var lab1Array:Array = new Array;
    private const TILE_WIDTH:uint = 25;
    private const TILE_HEIGHT:uint = 25;
    private const STAGE_WIDTH:uint = 550;
    private const STAGE_HEIGHT:uint = 400;
    private var horizontalBlocks = STAGE_WIDTH / TILE_WIDTH;
    private var verticalBlocks = STAGE_HEIGHT / TILE_HEIGHT;
    private var hitBlock:DisplayObject;


    private var leftDown: Boolean = false;
    private var rightDown: Boolean = false;
    private var botDown: Boolean = false;
    private var upDown: Boolean = false;



    public function Main() 
    {


        mc.x = 160;
        mc.y = 385;
        addChild(mc);


        for (var i:uint = 0 ; i < verticalBlocks ;  i++)
        {
            lab1Array[i] = new Array;

            for (var j:uint=0; j < horizontalBlocks; j++)
                {
                lab1Array[i].push(0);
                }


        }


         lab1Array = [
        [1,1,1,1,1,1,0,1,1,1,1,1,1,1,1,1,1,0,1,1,1,1],
        [1,1,1,1,1,1,0,1,1,1,1,1,1,1,1,1,1,0,1,1,1,1],

        [1,1,1,1,1,1,0,1,1,1,1,1,1,1,1,1,1,0,1,1,1,1],
        [1,1,1,1,1,1,0,1,1,1,1,1,1,1,1,1,1,0,1,1,1,1],

        [1,1,1,1,1,1,0,1,1,1,1,1,1,1,1,1,1,0,1,1,1,1]
        ];



        stage.addEventListener(KeyboardEvent.KEY_DOWN, checkKeysDown);
        stage.addEventListener(KeyboardEvent.KEY_UP, checkKeysUp);
        stage.addEventListener(Event.ENTER_FRAME, charManagement);

    }


    function checkKeysDown (event:KeyboardEvent):void
    {


        if (event.keyCode == 37 || event.keyCode == 65) 
        {
            leftDown = true;
        }
        if (event.keyCode == 38 || event.keyCode == 87) 
        {
            upDown = true;
        }
        if (event.keyCode == 39 || event.keyCode == 68) 
        {
            rightDown = true;
        }
        if (event.keyCode == 40 || event.keyCode == 83) 
        {
            botDown = true;
        }
    }

    function checkKeysUp (event:KeyboardEvent):void
    {   
        if (event.keyCode == 37 || event.keyCode == 65) 
        {
            leftDown = false;
        }
        if (event.keyCode == 38 || event.keyCode == 87) 
        {
            upDown = false;
        }
        if (event.keyCode == 39 || event.keyCode == 68) 
        {
            rightDown = false;
        }
        if (event.keyCode == 40 || event.keyCode == 83) 
        {
            botDown = false;
        }
    }

    function charManagement(event:Event) : void
    {


            if (leftDown)
            {
                mc.x -= mcSpeed;
            }
            if (rightDown)

            if (botDown)
            {
                mc.y += mcSpeed;
            }

    }

        function createLab():void 
    {
        for (var i = 0; i < lab1Array.length ; i++)

            for (var j = 0; j < lab1Array[i].length ; j++)
              {
                    if (lab1Array[i][j] == 1)
                  {
                        tile= new tile1;
                        tile.x = TILE_WIDTH*(j+0.5);
                        tile.y = TILE_HEIGHT*(i+0.5);

                  } 

              } 

         }
    }

}

}

Answer 1

很难根据您的代码给出答案，但hitTestObject应该在CharManagement函数内的键检测内部

if(leftDown)
{
 mc.x += mcSpeed;
 if mc.hitTestObject(tiles)
 {
  //add code for whatever you want to do
 }
}

我还需要看看你的tile1类，因为我相信它可能不是一个对象，因此为什么hittestObject永远不会返回true。

P.S。当你说它不工作时，这是否意味着它给你错误？或者它只是没有完成你想要的东西？

Answer 2

您可以使用磁贴来测试播放器这是通过在tile类中使用更新函数来完成的，而不是您当前使用的更新函数。这是这样做的 mc.hittestobject（本）;

使用瓷砖AS3进行迷宫碰撞检测
