C# 如何使用2个矩形变量绘制动画纹理？

我有个问题需要解决。我正在用cxna制作一个太空入侵者游戏。我一直在为入侵者学习本教程： 但我也有自己的代码来制作入侵者精灵表的动画。最后我画的是：

void Draw(SpriteBatch spriteBatch){
  for (int r = 0; r < m_InvaderRows; r++)
  {
    for (int c = 0; c < m_InvaderCollumns; c++)
    {
      spriteBatch.Draw(m_BotInvaderTex, m_BotInvaderPos, m_BotInvaderHitBox, Color.White, 0f, Vector2.Zero, 1.0f, SpriteEffects.None, 0);

      // ???

      spriteBatch.Draw(m_BotInvaderTex, m_BotInvadersRect[r, c], Color.White);
    }
  }
}

您必须创建一个创建精灵的调用，如本教程->。在这节课上，你还得放动画

m_BotInvestrHitbox=新矩形m_BotInvestrReframe*m_BotInvestrFrameWidth，0，m_BotInvestrFrameWidth，m_BotInvestrFrameHeight； m_BotInvestororigin=新载体2M_BotInvestorHitbox.X/2，m_BotInvestorHitbox.Y/2； m_Timer+=floatgameTime.ElapsedGameTime.millides； 如果m_定时器>m_间隔 { m_Botrunframe++； m_定时器=0f； } 如果m_BotRecurrenFrame==2 { m_Botrunframe=0； } m_BotInvestrHitbox=新矩形m_BotInvestrReframe*m_BotInvestrFrameWidth，0，m_BotInvestrFrameWidth，m_BotInvestrFrameHeight； m_BotInvestorRigin=新向量2m_BotInvestorHitbox.Width/2，m_BotInvestorHitbox.Height/2； int m_右侧=800； int m_LeftSide=0； 对于int r=0；rm_right side { m_BotrsDirection=左侧； m_BotrsChangeDirection=Y； } 如果m_BottersRect[r，c].X}在Game1.cs的绘制方法中
