关于第 9 行的结尾，我似乎在 Unity 中遇到了错误

Question

void FixedUpdate()
{
    ///rotate character model if stick is tilted right or left, but only if character is moving in that direction.
    if (IsInLocomotion () && ((direction >= 0 && horizontal >= 0) || (direction < 0 && horizontal < 0))) 
    {
        Vector3 rotationAmount = Vector3.Lerp (Vector3.zero, new Vector3 (0f, rotationDegreePerSecond* (horizontal < 0f ? -1f : 1f), 0f), Mathf.Abs);
        Quaternion deltaRotation = Quaternion.Euler (rotationAmount * Time.deltaTime);
        this.transform.rotation = (this.transform.rotation * deltaRotation);
    }

}

我的代码的这一特定部分给了我一个错误。如果有人碰巧知道它到底有什么问题，我将非常感激。

我不断收到错误

Assets/CharacterControllerLogics.cs(100,58)：错误 CS1502：最好的 重载方法匹配 `UnityEngine.Vector3.Lerp(UnityEngine.Vector3, UnityEngine.Vector3, float)' 有一些无效的参数

和

Assets/CharacterControllerLogics.cs(100,58)：错误 CS1503：参数 #3' cannot convertmethod group' 表达式来输入 `float'

Answer 1

您将Mathf.Abs（一个方法）传递给一个期望float 作为其第三个参数的方法。也许您应该为Mathf.Abs 提供一个值（其结果将是float 类型）？例如：

Vector3.Lerp (Vector3.zero, new Vector3 (0f, rotationDegreePerSecond * 
    (horizontal < 0f ? -1f : 1f), 0f), Mathf.Abs(42.0));
                                                ^^^^^^
