在 c# 中编码并使用 XNA 4.0 框架我正在尝试为玩家控制开发键盘和游戏控制器输入。
我的游戏控制器输入代码如下;
GamePadState gamepadState = GamePad.GetState(PlayerIndex.One);
if(gamepadState.ThumbSticks.Left.X != 0 || gamepadState.ThumbSticks.Left.Y != 0)
{
//Handles rotation
angle += thumbsticksMove(gamepadState); //handles Left.X and Left.Y input
normalize(); //normalizes angle and sets normalizedAngle = angle
this.Rotate(normalizedAngle); //takes value and passes it through Math helper
//atan and pi*2
//Ends handles rotation
pos += (angle * speed);
//Implementing framerate adjustment just for this class
timeSinceLastFrame += (float)gameTime.ElapsedGameTime.Milliseconds;
if (timeSinceLastFrame > millisecondsPerFrame)
{
timeSinceLastFrame -= millisecondsPerFrame;
Animation();
}
}
这会按预期移动玩家,并且精灵会翻转到正确的方向,但动画片段不起作用。精灵应该在输入时随着玩家的移动而动画。这在从键盘输入时效果很好,见下文;
if (Keyboard.GetState().IsKeyDown(Keys.Right))
{
input = Vector2.Zero;
input.X = 1;
//Handles rotation
angle.X = input.X;
normalize();
this.Rotate(normalizedAngle);
//Ends handles rotation
pos += (input * speed);
//Implementing framerate adjustment just for this class
timeSinceLastFrame += (float)gameTime.ElapsedGameTime.Milliseconds;
if (timeSinceLastFrame > millisecondsPerFrame)
{
timeSinceLastFrame -= millisecondsPerFrame;
Animation();
}
}
我很难弄清楚为什么它适用于键盘输入而不适用于游戏控制器输入。它几乎看起来好像它正在尝试制作动画,但从未完全超过第 3 个动画单元格,或者动画速度如此之快以至于看起来好像几乎没有动画。任何帮助将不胜感激!
