xna-4.0 - XNA游戏工作室简单精灵动画

Question

好的，所以我在写像泡泡一样的 2d 游戏，但我不想要某种非常复杂的动画。我想要这样的东西：我有 2 个玩家图像右面生物和左面生物图像的矩形大小完全相同，我也有：

Vector2 playerPosition宣布

player = Content.Load<Texture2D>("PlayerRight");在我的LoadContent

spriteBatch.Draw(player, playerPosition, Color.White);在我的绘图功能中

我想要的只是当我按下右/左箭头按钮时，我的播放器图像在右/左图像之间切换

我不知道什么样的代码以及我必须为该任务编写的位置。如果您需要有关该任务的更多信息，请告诉我

this is not best solution, but it could give you hint.

playerRight = Content.Load<Texture2D>("PlayerRight");
playerLeft = Content.Load<Texture2D>("PlayerLeft");
playerCameraFacing = Content.Load<Texture2D>("playerCameraFacing");

declare PlayerSprite as Texture2D in player class

update funciton pseudo:

PlayerSprite = playerCameraFacing ;
if key.left then PlayerSprite = playerLeft;
if key.right then PlayerSprite = playerRight;

draw function pseudo:

draw(PlayerSprite, Position, Color)
