清除XNA 4.0中绘制的SpriteFont
该代码主要用于显示用户触摸屏幕的次数。但问题是每次更新方法(XNA 4.0)都会绘制之前的纹理,因此无法读取计数。每次重绘时如何清除 SpriteFont 纹理?
//Code used to draw the Sprite Font.!
batch.DrawString(fontSegoe, "Touches "+count, new Vector2(100, 100), Color.Black, 0, Vector2.Zero, 1, SpriteEffects.None, 0f);
This code is used to basically display number of times the user touches the screen. But the problem is every time the Update method(XNA 4.0), the previous texture is Drawn upon , therefore the count cannot be read. How do i clear the SpriteFont texture each time when it is redrawn?.

确保在 Draw() 开始时清除屏幕
Make sure to clear the screen at the beginning of Draw()
