Question

当我在动作脚本3中调整按钮大小时，命中框会更改为文本，而不是我的作业示例中的方块：

以下是代码：

import flash.events.MouseEvent;

trace("Stage(X,Y):" + stage.stageWidth + "X" + stage.stageHeight);

stage.addEventListener(MouseEvent.MOUSE_MOVE, mousePosition);
clickMe.addEventListener(MouseEvent.CLICK, handleClicks); 
function mousePosition(event:MouseEvent) {

    if(clickMe.mouseX >= 0 && clickMe.mouseX <= clickMe.width && clickMe.mouseY >= 0 && clickMe.mouseY <= clickMe.height)
    {
        do
        {
            var newX = Math.floor(Math.random()*stage.stageWidth);
            var newY = Math.floor(Math.random()*stage.stageHeight)

        }while(newX >= stage.stageWidth - clickMe.width || newY >= stage.stageHeight - clickMe.height)

        clickMe.x = newX;
        clickMe.y = newY;

        if(clickMe.width > 50)
        {
            clickMe.width=clickMe.width - 5;
            clickMe.height = clickMe.width - 5;
        }
    }
}

function handleClicks(event:MouseEvent)
{
    trace("Button Clicked!");
}

如何在调整对象大小时让hitbox保持不变？

Answer 1

这似乎是一种更好，更清晰的方法（假设您将clickMe剪辑移动到随机位置并将其缩小5px）

import flash.events.MouseEvent;

clickMe.addEventListener(MouseEvent.ROLL_OVER, moveSquare);

function moveSquare(e:MouseEvent):void
{
    var newX       = Math.floor(Math.random()*stage.stageWidth);
    var newY       = Math.floor(Math.random()*stage.stageHeight);
    clickMe.x      = newX;
    clickMe.y      = newY;
    clickMe.width  = clickMe.width - 5;
    clickMe.height = clickMe.height - 5;
}

更改按钮大小会影响其中的mouseX / mouseY值。因此，不要依赖它，只需使用基于按钮位置和大小的检查。

if(mouseX >= clickMe.x && mouseX <= clickMe.x+clickMe.width && mouseY >= clickMe.y && mouseY <= clickMe.y+clickMe.height)

如何在不更改hitbox的情况下调整actionscript 3中的对象的大小？
