亲爱的先生们美好的一天。我在角色的动画和控件方面遇到了问题。我的问题是，每当我尝试按左右箭头键时，我的播放器都会上下移动，而不是左右移动。我确实尝试过调试我的代码，但我仍然无法找出代码的哪一部分是错误的。这就是为什么我要求你们查看我的代码，并可能知道代码的哪一部分是错误的或需要改进。
这是我的播放器代码：
public class DugmanPlayer {
public enum state
{
standby,
walking,
digging,
dying
}
public enum dir
{
left,
right,
up,
down
}
public static float WIDTH;
public static float HEIGHT;
static float speedmax = 30f;
static float damping = 0.9f;
dir d = dir.up;
public Vector2 position = new Vector2();
public Vector2 speed = new Vector2();
state st = state.walking;
public float statetime = 0;
public void UpdatePlayer(float deltatime)
{
if(deltatime==0)return;
statetime += deltatime;
//rightwalking
if(Math.abs(speed.x) > speedmax) {
speed.x = Math.signum(speed.x) * speedmax;
if(d != dir.left)d = dir.right;
st = state.walking;
}
if(Math.abs(speed.x) < 1) {
speed.x = 0;
if(st!=state.walking)st = state.standby;
d=dir.right;
}
//upwalking
if(Math.abs(speed.y) > speedmax) {
speed.y = Math.signum(speed.y) * speedmax;
if(d != dir.down)d = dir.up;
st = state.walking;
}
if(Math.abs(speed.y) < 1) {
speed.y = 0;
if(st != state.walking)st = state.standby;
d=dir.up;
}
if(Math.abs(-speed.x)>speedmax)
{
speed.x = Math.signum(-speed.x) * speedmax;
if(d != dir.right)d = dir.left;
st = state.walking;
}
if(Math.abs(-speed.x)<1)
{
speed.x = 0;
if(st!=state.walking)st = state.standby;
d=dir.up;
}
if(Math.abs(-speed.y)>speedmax){
speed.y = Math.signum(-speed.y) * speedmax;
if(d != dir.up)d = dir.down;
st = state.walking;
}
if(Math.abs(-speed.y)<1)
{
speed.y = 0;
if(st!=state.walking)st = state.standby;
d=dir.down;
}
speed.scl(deltatime);
position.add(speed);
speed.scl(1/deltatime);
// Apply damping to the velocity on the x-axis so we don't
// walk infinitely once a key was pressed
speed.x *= damping;
speed.y *= damping;

我对我的角色类所做的是，它将包含我的角色的所有输入，将动画渲染到特定的状态和方向。
