如何在mouse_click事件中防止重複函數？

if (Mouse.GetState().LeftButton == ButtonState.Pressed) 
{ 
      shoot_sound.Play(); 
      // it plays the sound more than once 
      // i'd like to play it just once and stop ! 
      // how to prevent key repeating 
} 

Answer 1

您可以通過此代碼段檢查是否發生了完整的點擊。

lastMouseState = currentMouseState; 
currentMouseState = Mouse.GetState(); 
if (lastMouseState.LeftButton == ButtonState.Released && currentMouseState.LeftButton == ButtonState.Pressed) 
{ 
    // React to the click of the mouse 
    shoot_sound.Play(); 
} 

Answer 2

我不知道確切的代碼，但我想你想是這樣的..

// Create an instance of the sound - makes it easier to manage and deal with 
SoundEffectInstance sei = yourSound.CreateInstance(); 

// then when you go to play the sound make sure it isn't playing before platying it... 

if (Mouse.GetState().LeftButton == ButtonState.Pressed) 
{ 
    if (sei.State == SoundState.Playing) 
    { 
     yourSound.Play(); 
    } 
} 

對不起直接跳進一個答案問過，但我沒有足夠的聲譽只是評論，所以請告訴我，如果我對你的問題感到困惑。如果是循環播放，請嘗試使用oldMouseState和newMouseState技術來檢查您是否在播放聲音之前單擊並釋放了鼠標。真的希望這有助於。
