actionscript-3 - Adobe 动画碰撞

Question

我正在使用 AS3 在 adobe animate 中制作游戏。我想在以下时间停止我的方 block 它与左边的障碍物发生碰撞而不让它通过。我的盒子的实例名称称为“盒子”，我的障碍物称为“左”和“右”。

这是我舞台的图片:image of stage

这是我到目前为止移动盒子的代码:

var upPressed:Boolean = false;
var downPressed:Boolean = false;
var leftPressed:Boolean = false;
var rightPressed:Boolean = false;

box.addEventListener(Event.ENTER_FRAME, fl_MoveInDirectionOfKey);
stage.addEventListener(KeyboardEvent.KEY_DOWN, fl_SetKeyPressed);
stage.addEventListener(KeyboardEvent.KEY_UP, fl_UnsetKeyPressed);

function fl_MoveInDirectionOfKey(event:Event)
{
  if (leftPressed)
  {
     box.x -= 5;
  }

  if (rightPressed)
  {
     box.x += 5;
  } 
}

function fl_SetKeyPressed(event:KeyboardEvent):void
{   
  switch (event.keyCode)
  {
    case Keyboard.LEFT:
    {
        leftPressed = true;
        break;
    }
    case Keyboard.RIGHT:
    {
        rightPressed = true;
        break;
    }
  }
}

function fl_UnsetKeyPressed(event:KeyboardEvent):void
{
 switch (event.keyCode)
 {  
    case Keyboard.LEFT:
    {
        leftPressed = false;
        break;
    }
    case Keyboard.RIGHT:
    {
        rightPressed = false;
        break;
    }
  }
}

非常非常感谢!

你需要类似的东西

if (box.hitTestObject(left)) box.x = left.x + left.width;
if (box.hitTestObject(right)) box.x = right.x  - box.width;

添加到fl_MoveInDirectionOfKey函数的末尾
