XNA 第7課 陣列

XNA 第7課 陣列

1.     宣告陣列元件(5x5=25)

        Ball [] arrayBall;

        int Ballcnt = 5;

2.     Initialized方法加入物件

arrayBall = new Ball[Ballcnt * Ballcnt];

            for (int i = 0; i < Ballcnt; i++)

                for (int j = 0; j < Ballcnt; j++)

                {

                    arrayBall[i * Ballcnt + j] = new Ball();

                    arrayBall[i * Ballcnt + j].Position.X = j * 60;

                    arrayBall[i * Ballcnt + j].Position.Y = i * 60;

                }

3.     Update方法加入陣列物件更新邏輯

for (int i = 0; i < Ballcnt; i++)

                for (int j = 0; j < Ballcnt; j++)

                    UpdateArray(gameTime, arrayBall[i * Ballcnt + j]);

            base.Update(gameTime);

        }

        void UpdateArray(GameTime gameTime, Ball BallSprite)

4.     Update方法加入陣列物件更新邏輯

for (int i = 0; i < Ballcnt; i++)

  for (int j = 0; j < Ballcnt; j++)

    UpdateArray(gameTime, arrayBall[i * Ballcnt + j]);

  

        void UpdateArray(GameTime gameTime, Ball BallSprite) …

5.     Draw方法加入陣列物件繪圖

for (int i = 0; i < Ballcnt; i++)

for (int i = 0; i < Ballcnt; i++)

   for (int j = 0; j < Ballcnt; j++)

     spriteBatch.Draw(spriteTexture, arrayBall[i * Ballcnt + j].Position, Color.White); /
