製作基本攻擊動畫取決於按鍵XNA C＃

我有一個2D角色扮演遊戲正在進行，當我按下某個鍵時，我希望我的角色擺動一把劍，劍的擺動是由3個角色組成的。製作基本攻擊動畫取決於按鍵XNA C＃

這是我竟能迄今代碼：編輯：根據要求，我copypasted在我的攻擊動畫代碼是在整個類

眼下，它的作用。當我揮杆的時候，不要超越攻擊的第一個精靈，我不完全確定如何使它發生。如果有人能給我一個提示或者類似的提示，我可以讓它通過整個代碼，以便按下一個按鈕就可以完成一個完整的操作。事先感謝！

如果你保持按下按鈕，然後它的工作原理？ –

定義一個全局變量

bool isAnimationRunning = false;

，然後改變你這樣的代碼：

if (ks.IsKeyDown(Keys.A) && directionPointer == 1 && oldKs.IsKeyUp(Keys.A)) 
{ 
    isAnimationRunning = true; 
} 

if(isAnimationRunning) 
{ 
    attackTime += gameTime.ElapsedGameTime.Milliseconds; 
    if (attackTime > 1 && attackTime < 100) 
    { 
     currentSprite = new Rectangle(3, 46, 32, 16); 
    } 
    else if (attackTime < 200 && attackTime > 100) 
    { 
     currentSprite = new Rectangle(33, 61, 32, 32); 
    } 
    else if (attackTime > 200 && attackTime < 300) 
    { 
     currentSprite = new Rectangle(61, 65, 16, 32); 
    } 
    else if (attackTime > 300) 
    { 
     attackTime = 0; 
     isAnimationRunning = false; 
    } 
}

我想說這是有效的，但它不夠奇怪。這應該。它看起來很正確o.o –

IsAnimationRunning是全局定義的，還是在方法內定義的？ –

它是全局定義的，當按鈕被按下時，他開始攻擊，所以這部分工作。現在我的角色不再是一旦我停止移動就揮動他的劍，而是凍結在第一個攻擊精靈身上。所以基本上，我認爲代碼不會達到最後一個代碼塊。嘗試刪除其他的，並試圖讓一段時間（isAnimationRunning），而沒有幫助。 –
