移動一個對象在另一個在as3

Question

好吧，所以我有一個character_mc，移動鼠標點擊，logtxt dyanamic文本框和mc命名$框。相機跟隨角色，當日志和$盒保持放置時。

我希望他們留在舞臺上的同一點（意思是我希望他們留在相機的相同位置）我想知道我可能會爲此做些什麼？我試圖把它們放在一個影片剪輯中，但它並沒有真正縫合，所以我放棄了這個想法。

你可以做的是把所有相關的對象使用精靈自己的層上。

這是一個有點難以理解，你在你的例子在做什麼，但這裏的 的你可以做什麼一個簡單的例子：

// Add all your game related objects to this Sprite - characters, enemies etc. 
private var cameraContainer:Sprite = new Sprite 
// Add all your hud objects to this Sprite - logtxt, $box etc. 
private var hudContainer:Sprite = new Sprite(); 

public function Main() { 
    cameraContainer.addChild(character_mc); 
    cameraContainer.addChild(enemy01); 
    cameraContainer.addChild(enemy02); 
    ... 

    hudContainer.addChild(logtxt); 
    hudContainer.addChild($box); 
} 

public function charLoop(event:Event) { 
    // Here you should not move all the objects relative to the player but instead 
    // move the player and then move the camera relative to the player 
    character_mc.x += character_mc['moveX']; 
    character_mc.y += character_mc['moveY']; 

    // Reposition the camera and everything else will move 
    // - Add half the screen size to centre the player on the screen 
    cameraContainer.x = -character_mc.x + halfScreenWidth; 
    cameraContainer.y = -character_mc.y + halfScreenHeight; 
}
