让相机跟随玩家对象在 3D 空间中的位置和旋转（Unity3d）

Question

我的目标是为我的太空战斗机概念验证游戏制作一个平滑的“跟随相机”。 相机应该在所有轴上匹配目标对象的滚转。

为此，我从统一答案站点“窃取”并修改了此代码，它对 X 和 Y（俯仰和偏航）运行良好，但它拒绝滚动。

代码：

public float Distance;
public float Height;
public float RotationDamping;
public GameObject Target;

void LateUpdate()
{
    var wantedRotationAngleYaw = Target.transform.eulerAngles.y;
    var currentRotationAngleYaw = transform.eulerAngles.y;

    var wantedRotationAnglePitch = Target.transform.eulerAngles.x;
    var currentRotationAnglePitch = transform.eulerAngles.x;

    var wantedRotationAngleRoll = Target.transform.eulerAngles.z;
    var currentRotationAngleRoll = transform.eulerAngles.z;

    currentRotationAngleYaw = Mathf.LerpAngle(currentRotationAngleYaw, wantedRotationAngleYaw, RotationDamping * Time.deltaTime);

    currentRotationAnglePitch = Mathf.LerpAngle(currentRotationAnglePitch, wantedRotationAnglePitch, RotationDamping * Time.deltaTime);

    currentRotationAngleRoll = Mathf.LerpAngle(currentRotationAngleRoll, wantedRotationAngleRoll, RotationDamping * Time.deltaTime);

    var currentRotation = Quaternion.Euler(currentRotationAnglePitch, currentRotationAngleYaw, currentRotationAngleRoll);

    transform.position = Target.transform.position;
    transform.position -= currentRotation * Vector3.forward * Distance;

    transform.LookAt(Target.transform);
    transform.position += transform.up * Height;
}

Answer 1

如果你解释了你想要做什么，我会更确定这个答案，但你应该考虑在currentRotation * Vector3.up而不是transform.up的方向上移动Height 。 此外，请考虑在调用LookAt时使用currentRotation * Vector3.up设置本地向上方向：

transform.position = Target.transform.position;
transform.position -= currentRotation * Vector3.forward * Distance;

Vector3 currentUp = currentRotation * Vector3.up;
transform.LookAt(Target.transform, currentUp);
transform.position += currentUp * Height;
