将对象移动到另一个对象位置

flashdevelop flash-cs6 containers actionscript-3

嘿,大家好,我在试着让它正常工作时遇到了一些麻烦。我有一个MC对象,叫做 character 还有一个叫做“点”。我有一个容器对象,名为 planetContainer 性格 到 飞机容器 planets 也会添加到容器中。我面临的主要问题是,当点通电激活时,我希望点离开其他行星并移动到 Points 超出并将其连接到

以下是我如何设置角色:

    private function newCounterClockWise():void 
    {
        planetContainer.addChild(character);
        character.rotation = (Math.atan2(character.y - planetHit.y, character.x - planetHit.x) * 180 / Math.PI);
    }

如何将点添加到行星:

private function addPoints():void 
    {
        points = new mcPoints();
        var planetPosition:Point = planetContainer.parent.localToGlobal(new Point(0, 0));  
        points.x = planetPosition.x;
        points.y = planetPosition.y;
        outerPlanets.addChild(points);
        aPointsArray.push(points);
    }

现在,这是处理移动到角色的点的主要函数,但它不能正常工作。积分会移动,但它们会从屏幕上移开,或者导致游戏有点调整,并做不同的事情。“magnetHandler();也在我的EnterFRame事件中:

private function magnetHandler():void 
    {
        for (var i:int = 0; i < aPointsArray.length; i++)
        {
            var currentPoints:mcPoints = aPointsArray[i];
            var characterPosition:Point = planetContainer.parent.globalToLocal(new Point(character.x, character.y));  

            if (currentPoints.hitTestObject(playScreen.mcPointsHit))
            {
                trace("POINTS MID STAGE");
                currentPoints.x -= (currentPoints.x - characterPosition.x);
                currentPoints.y -= (currentPoints.y - characterPosition.y);
                //currentPoints.x = character.x;
                //currentPoints.y = character.y;
                //TweenMax.to(currentPoints, 0.5, {x:characterGlobalPosition.x, y:characterGlobalPosition.y , ease:Power1.easeInOut } );
            }
        }
    }

很难完全理解你的问题(或者理解为什么你把彼此相关的东西放在不同的容器中),但很可能这一行就是它的落脚点:

var characterPosition:Point = planetContainer.parent.globalToLocal(new Point(character.x, character.y));

currentPoints

//first, find the global position of character:
var globalCharacterPoint:Point = character.localToGlobal(new Point());

//then, convert that to the currentPoints parent local space:
var localCharacterPoint:Point = currentPoints.parent.globalToLocal(globalCharacterPoint);

此外,在您的代码中:

    points = new mcPoints();
    var planetPosition:Point = planetContainer.parent.localToGlobal(new Point(0, 0));  
    points.x = planetPosition.x;
    points.y = planetPosition.y;

您将获得planetContainer父对象的全局空间,这可能不是您想要的。您可能想要:

planetContainer.localToGlobal(new Point());  //this gives you the global location of the planet container's top left corner

points 反对 outerPlanets ,您可能希望转换到其局部空间(除非全局定位为0,0,否则这并不特别重要)。

var outerPoint:Point = outerPlanets.globalToLocal(planetPosition);
points.x = outerPoint.x;
points.y = outerPoint.y;
