Question

所以我一直试图让我的角色移动和旋转，就像游戏中的常规方式一样。这是：以一定的速度向前移动，并能够转动角色的方向移动到其他方向。

我使用角色控制器，到目前为止，一切都已成功。但是，一旦我实际上将角色旋转到不同的方向，它就会向我发出错误。

错误：错误CS0029：无法隐式转换类型void' to UnityEngine.Vector3＆＃39;

当我删除Vector3左行时，它再次起作用。所以我认为它与团结有关，不希望我使用transform.Rotate

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class basicmove : MonoBehaviour {


    public float walkSpeed;
    public float turnSpeed;


    void FixedUpdate() {
        CharacterController controller = GetComponent<CharacterController>();
        Vector3 forward = transform.TransformDirection(Vector3.forward);
        Vector3 left = transform.Rotate(Vector3.left*Time.deltaTime);

        if(Input.GetKey(KeyCode.W)){
            controller.SimpleMove(forward * walkSpeed);
        }
        if(Input.GetKey(KeyCode.A)){
            controller.SimpleMove(left * turnSpeed);
        }
    }
}

要同时转动和移动，你可以做一些事情，最简单的是：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class basicmove : MonoBehaviour 
{
    public float walkSpeed;
    public float turnSpeed;
    private CharacterController controller;

    void Start() 
    {
        // Set here, so we don't have to constantly call getComponent.
        controller = getComponent<CharacterController>();
    }

    void FixedUpdate() 
    {
        if(controller != null) 
        {

            if(Input.GetKey(KeyCode.W))
            {
                // transform.forward is the forward direction of your object
                controller.SimpleMove(transform.forward * walkSpeed * Time.deltaTime);
            }

            if(Input.GetKey(KeyCode.A))
            {
                // transform.Rotate will rotate the transform using the information passed in.
                transform.Rotate(0, turnSpeed * Time.deltaTime, 0);
            }

            if(Input.GetKey(KeyCode.D))
            {
                // transform.Rotate will rotate the transform using the information passed in.
                transform.Rotate(0, -turnSpeed * Time.deltaTime, 0);
            }
        }
    }
}
