沒有合適的方法來覆蓋更新（GameTime gameTime）

Question

我得到上述錯誤，這阻止了我測試以查看我的相機是否工作。該代碼是：

protected override void Update(GameTime gameTime) 
{ 
    KeyboardState keyBoardState = Keyboard.GetState(); 

    //Rotate Cube along its Up Vector 
    if (keyBoardState.IsKeyDown(Keys.X)) 
    { 
     cubeWorld = Matrix.CreateFromAxisAngle(Vector3.Up, .02f) * cubeWorld; 
    } 
    if (keyBoardState.IsKeyDown(Keys.Z)) 
    { 
     cubeWorld = Matrix.CreateFromAxisAngle(Vector3.Up, -.02f) * cubeWorld; 
    } 

    //Move Cube Forward, Back, Left, and Right 
    if (keyBoardState.IsKeyDown(Keys.Up)) 
    { 
     cubeWorld *= Matrix.CreateTranslation(cubeWorld.Forward); 
    } 
    if (keyBoardState.IsKeyDown(Keys.Down)) 
    { 
     cubeWorld *= Matrix.CreateTranslation(cubeWorld.Backward); 
    } 
    if (keyBoardState.IsKeyDown(Keys.Left)) 
    { 
     cubeWorld *= Matrix.CreateTranslation(-cubeWorld.Right); 
    } 
    if (keyBoardState.IsKeyDown(Keys.Right)) 
    { 
     cubeWorld *= Matrix.CreateTranslation(cubeWorld.Right); 
    } 
} 

導致錯誤的行是：

protected override void Update(GameTime gameTime) 

Answer 1

你是不是從GameComponent繼承，你有兩個選擇：

1. Inherite從GameComponent類：

   public class YourCameraClass : GameComponent { .... } 
   

2. 在您的更新方法聲明中刪除「覆蓋」關鍵字：

   public void Update(Gametime gametime) {....}
