c# - 如何更改第三人称控制器动作

问题描述

我正在使用 Unity Standard 资产中的第三人称控制器运动。我想改变运动的方向，比如当我按“W”或“向上箭头键”时它正在向右移动，当我按“D”或“向右箭头键”时它正在向后移动，当我按“S”或“向下箭头键”它向左移动，当我按“A”或“向左箭头键”时它正在向前移动。

运动脚本：

using System;
using UnityEngine;
using UnityStandardAssets.CrossPlatformInput;

namespace UnityStandardAssets.Characters.ThirdPerson
{
    [RequireComponent(typeof (ThirdPersonCharacter))]
    public class ThirdPersonUserControl : MonoBehaviour
    {
        private ThirdPersonCharacter m_Character; // A reference to the ThirdPersonCharacter on the object
        private Transform m_Cam;                  // A reference to the main camera in the scenes transform
        private Vector3 m_CamForward;             // The current forward direction of the camera
        private Vector3 m_Move;
        private bool m_Jump;                      // the world-relative desired move direction, calculated from the camForward and user input.


        private void Start()
        {
            // get the transform of the main camera
            if (Camera.main != null)
            {
                m_Cam = Camera.main.transform;
            }
            else
            {
                Debug.LogWarning(
                    "Warning: no main camera found. Third person character needs a Camera tagged \"MainCamera\", for camera-relative controls.", gameObject);
                // we use self-relative controls in this case, which probably isn't what the user wants, but hey, we warned them!
            }

            // get the third person character ( this should never be null due to require component )
            m_Character = GetComponent<ThirdPersonCharacter>();
        }


        private void Update()
        {
            if (!m_Jump)
            {
                m_Jump = CrossPlatformInputManager.GetButtonDown("Jump");
            }
        }


        // Fixed update is called in sync with physics
        private void FixedUpdate()
        {
            // read inputs
            float h = CrossPlatformInputManager.GetAxis("Horizontal");
            float v = CrossPlatformInputManager.GetAxis("Vertical");
            bool crouch = Input.GetKey(KeyCode.C);

            // calculate move direction to pass to character
            if (m_Cam != null)
            {
                // calculate camera relative direction to move:
                m_CamForward = Vector3.Scale(m_Cam.forward, new Vector3(1, 0, 1)).normalized;
                m_Move = v*m_CamForward + h*m_Cam.right;
            }
            else
            {
                // we use world-relative directions in the case of no main camera
                m_Move = v*Vector3.forward + h*Vector3.right;
            }
#if !MOBILE_INPUT
            // walk speed multiplier
            if (Input.GetKey(KeyCode.LeftShift)) m_Move *= 0.5f;
#endif

            // pass all parameters to the character control script
            m_Character.Move(m_Move, crouch, m_Jump);
            m_Jump = false;
        }
    }
}

谁能告诉我如何改变这些方向

解决方案


找到这部分代码：

float h = CrossPlatformInputManager.GetAxis("Horizontal");
float v = CrossPlatformInputManager.GetAxis("Vertical");

并交换它们：

float v = CrossPlatformInputManager.GetAxis("Horizontal") * -1;
float h = CrossPlatformInputManager.GetAxis("Vertical") * -1;

更新：为了纠正相反的运动方向，我添加了 -1
