Hittesting對一個級別建設陣列

我正在建立一個自上而下（鳥瞰）遊戲的閃光燈，一個相當簡單的概念，一個早期的塞爾達傳說或最終幻想遊戲。我已經建立了關卡，並且角色添加和移動，帶有滾動相機，但是有一個問題讓我感到困擾。 Hittesting。Hittesting對一個級別建設陣列

該級別使用數組創建 - 一個簡單的[1,1,1];數組，它檢查數組中的值是否匹配，然後創建一個簡單的方形Sprite並將其添加到容納每個項目的較大Sprite。最後，玩家將被添加到舞臺上，並可以使用箭頭鍵進行控制。我使用這個作爲運動系統：

stage.addEventListener(KeyboardEvent.KEY_DOWN, checkDown); 
stage.addEventListener(KeyboardEvent.KEY_UP, checkUp); 
stage.addEventListener(Event.ENTER_FRAME, update); 

function checkDown(e:KeyboardEvent):void { 
    switch (e.keyCode) { 
    case 65 : 
     leftDown = true; 
     break; 
    case 37 : 
     leftDown = true; 
     break; 
    case 68 : 
     rightDown = true; 
     break; 
    case 39 : 
     rightDown = true; 
     break; 
    case 87 : 
     upDown = true; 
     break; 
    case 38 : 
     upDown = true; 
     break; 
    case 83 : 
     downDown = true; 
     break; 
    case 40 : 
     downDown = true; 
     break; 
} 
} 

function checkUp(e:KeyboardEvent):void { 
switch (e.keyCode) { 
    case 65 : 
     leftDown = false; 
     break; 
    case 37 : 
     leftDown = false; 
     break; 
    case 68 : 
     rightDown = false; 
     break; 
    case 39 : 
     rightDown = false; 
     break; 
    case 87 : 
     upDown = false; 
     break; 
    case 38 : 
     upDown = false; 
     break; 
    case 83 : 
     downDown = false; 
     break; 
    case 40 : 
     downDown = false; 
     break; 
} 
} 

function update(e:Event):void { 
if (upDown) { 
    if (genericHolder.y >= boundariesLevelOne[(room*4) - 4]) { 
     genericHolder.y = boundariesLevelOne[(room*4) - 4]; 
     Player.y-=power; 
    } 
    if (genericHolder.y < boundariesLevelOne[(room*4) - 4]) { 
     genericHolder.y+=power; 
    } 
    Player.Stand.visible = false; 
    Player.Forwards.visible = false; 
    Player.Rights.visible = false; 
    Player.Lefts.visible = false; 
    Player.Backwards.visible = true; 
    playerDirection = 2; 
} 
if (downDown) { 
    if (genericHolder.y <= boundariesLevelOne[(room*4) - 3]) { 
     genericHolder.y = boundariesLevelOne[(room*4) - 3]; 
     Player.y+= power; 
    } 
    if (genericHolder.y > boundariesLevelOne[(room*4) - 3]) { 
     genericHolder.y-=power; 
    } 
    Player.Stand.visible = false; 
    Player.Backwards.visible = false; 
    Player.Rights.visible = false; 
    Player.Lefts.visible = false; 
    Player.Forwards.visible = true; 
    playerDirection = 1; 
} 
if (leftDown) { 
    if (genericHolder.x >= boundariesLevelOne[(room*4) - 2]) { 
     genericHolder.x = boundariesLevelOne[(room*4) - 2]; 
     Player.x -= power; 
    } 
    if (genericHolder.x < boundariesLevelOne[(room*4) - 2]) { 
     genericHolder.x+=power; 
    } 
    Player.Stand.visible = false; 
    Player.Backwards.visible = false; 
    Player.Forwards.visible = false; 
    Player.Rights.visible = false; 
    Player.Lefts.visible = true; 
    playerDirection = 4; 
} 
if (rightDown) { 
    if (genericHolder.x <= boundariesLevelOne[(room*4) - 1]) { 
     genericHolder.x = boundariesLevelOne[(room*4) - 1]; 
     Player.x += power; 
    } 
    if (genericHolder.x > boundariesLevelOne[(room*4) - 1]) { 
     genericHolder.x-=power; 
    } 
    Player.Stand.visible = false; 
    Player.Backwards.visible = false; 
    Player.Forwards.visible = false; 
    Player.Lefts.visible = false; 
    Player.Rights.visible = true; 
    playerDirection = 3; 
} 
if (!upDown && !downDown && !leftDown && !rightDown) { 
    Player.Backwards.visible = false; 
    Player.Forwards.visible = false; 
    Player.Rights.visible = false; 
    Player.Lefts.visible = false; 
    Player.Stand.visible = true; 
    Player.Stand.gotoAndStop(playerDirection); 
} 
if (Player.Stand) { 
    Player.Stand.gotoAndStop(playerDirection); 
    } 
}

TL; DR背景移動而不是玩家，移動由變量控制。

如何對我添加的任何精靈進行Hittest測試？目前，如果我嘗試對特定的Sprite進行Hittest測試，它會再次測試整個Sprite持有者，而不是我想要的特定Sprite。任何幫助非常感謝，謝謝。
