我花了 8 个小时试图找到解决方案。
所以这是我的问题。我的船在旋转，就像它在绕着什么东西旋转，比如一根绳子。当我离起始位置越来越远时，我开始旋转得越来越奇怪。就像我附着在一根绳子上一样。
这是旋转和运动的代码。
public void MoveShip(List<InputAction> InputActionList, GameTime gameTime)
{
float second = (float)gameTime.ElapsedGameTime.TotalSeconds;
float currentTurningSpeed = second * TurningSpeed;
float leftRightRotation = 0;
float upDownRotation = 0;
float linearLeftRightRotation = 0;
foreach(InputAction action in InputActionList)
{
switch(action)
{
case InputAction.Left:
leftRightRotation -= currentTurningSpeed;
break;
case InputAction.Right:
leftRightRotation += currentTurningSpeed;
break;
case InputAction.Up:
upDownRotation += currentTurningSpeed;
break;
case InputAction.Down:
upDownRotation -= currentTurningSpeed;
break;
case InputAction.IncreaseSpeed:
if (ShipSpeed < MaxShipSpeed)
ShipSpeed += Acceleration;
break;
case InputAction.DecreaseSpeed:
if (ShipSpeed > MinShipSpeed)
ShipSpeed -= Acceleration;
break;
case InputAction.LinearLeft:
linearLeftRightRotation += currentTurningSpeed;
break;
case InputAction.LinearRight:
linearLeftRightRotation -= currentTurningSpeed;
break;
case InputAction.Fire1:
WeaponSystem2D.RequestFire(ShipPosition, ShipRotation);
break;
}
}
Quaternion currentRotation = Quaternion.CreateFromAxisAngle(new Vector3(0, 0, 1), leftRightRotation) *
Quaternion.CreateFromAxisAngle(new Vector3(1, 0, 0), upDownRotation) *
Quaternion.CreateFromAxisAngle(new Vector3(0, 1, 0), linearLeftRightRotation);
currentRotation.Normalize();
ShipRotation *= currentRotation;
ShipPosition *= Vector3.Transform(new Vector3(0, 0, 1), ShipRotation) * (ShipSpeed * second);
ShipWorld = Matrix.CreateFromQuaternion(ShipRotation) * Matrix.CreateTranslation(ShipPosition);
}
问题是什么？为什么要这样做？我希望船在一角钱上旋转，因为它是空间。
编辑：-模型不是问题。
编辑2：没关系，旋转实际上是在工作，是我的天空盒坏了！
