Unity-人物移动

人物模型

参考以下视频：

如何在Unity中导入pmx格式的MMD模型_哔哩哔哩_bilibili

用的是原神模型，这里要注意导入后把人物模型的Rig换为Humanoid

人物动作

使用的Unity-Chan! Model的动作，在asset store找到这个资源添加并导入就行。

设置动画

使用blend-tree混合人物移动的动画

代码脚本编写

输入系统

• 安装插件

• 为Input Actions创建按键映射

在这之前要创建Input Actions，并 勾选生成C#类

• 脚本控制输入

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

namespace Player.Common
{
    /**
     * 输入系统
     */
     public class InputSystem : MonoBehaviour
    {
        [Header("移动")]
        [HideInInspector]public float horizontal;
        [HideInInspector]public float vertical;
        [HideInInspector]public float moveAmount;
        [HideInInspector]public bool isRun;

        // private float mouseX;
        // private float mouseY;


        private InputControls inputControls;

        private Vector2 movementInput;
        [HideInInspector]
        public bool jumpInput;
        private Vector2 cameraInput;
        public void OnEnable()
        {
            if (inputControls == null)
            {
                inputControls = new InputControls();

                inputControls.Player.Move.performed +=
                    inputControls => movementInput = inputControls.ReadValue<Vector2>();
                inputControls.Player.Jump.performed +=
                    inputControls => jumpInput = inputControls.ReadValueAsButton();
                inputControls.Player.Run.performed +=
                    inputControls => isRun = inputControls.ReadValueAsButton();

                // inputControls.PlayerMovment.Camera.performed += i => cameraInput = i.ReadValue<Vector2>();
            }

            inputControls.Enable();
        }

        public void OnDisable()
        {
            inputControls.Disable();
        }

        public void UpdateMoveInput()
        {
            horizontal = movementInput.x;
            vertical = movementInput.y;
            moveAmount = Mathf.Clamp01(Mathf.Abs(horizontal) + Mathf.Abs(vertical));

            // mouseX = cameraInput.x;
            // mouseY = cameraInput.y;
        }


    }

}

动画脚本

using UnityEngine;

namespace Player.Animation
{
    public class AnimationHandler : MonoBehaviour
    {
        [HideInInspector]
        public Animator anim;

        [HideInInspector]public bool IsRun;
        [HideInInspector]public bool IsWalk;

        private int vertical;
        private int horizontal;

        public bool canRotate = true;

        public void Initialize()
        {
            anim = GetComponent<Animator>();
            vertical = Animator.StringToHash("Vertical");
            horizontal = Animator.StringToHash("Horizontal");
        }

        public void UpdateAnimatorValues(bool isWalk,bool isRun,float verticalMovement, float horizontalMovement)
        {

            anim.SetBool("IsRun",isRun);
            anim.SetBool("IsWalk",isWalk);
            // if (isRun)
            // {
                verticalMovement = Mathf.Abs(verticalMovement);
                horizontalMovement = Mathf.Abs(horizontalMovement);
                anim.SetFloat(vertical,verticalMovement,0.1f,Time.deltaTime);
                anim.SetFloat(horizontal,horizontalMovement,0.1f,Time.deltaTime);
            // }

        }

        public void CanRotate()
        {
            canRotate = true;
        }

        public void StopRotation()
        {
            canRotate = false;
        }

    }

}

人物引擎

using Player.Animation;
using UnityEngine;

namespace Player.Common
{
    public class PlayerMotor : MonoBehaviour
    {
        [Header("基本属性")]
        private InputSystem inputSystem;
        private Rigidbody rigidbody;
        [HideInInspector]
        public Transform playerTransForm;
        [HideInInspector]
        public AnimationHandler animationHandler;

        [Header("移动参数")]
        public float WalkSpeed = 5f;
        public float RunSpeed = 12f;
        private Vector3 moveDirection;
        public float RotateSpeed = 5f;

        void Start()
        {
            inputSystem = GetComponent<InputSystem>();
            rigidbody = GetComponent<Rigidbody>();
            playerTransForm = GetComponent<Transform>();
            animationHandler = GetComponentInChildren<AnimationHandler>();
        }

        void Update()
        {
            PlayerMove();
            PlayerRotate(moveDirection);

        }

        private void PlayerMove()
        {
            inputSystem.UpdateMoveInput();
            moveDirection = new Vector3(inputSystem.horizontal,0,inputSystem.vertical);
            moveDirection *= WalkSpeed;
            rigidbody.velocity = moveDirection;


            animationHandler.Initialize();
            bool  isWalk = (Mathf.Abs(inputSystem.horizontal) > 0 || Mathf.Abs(inputSystem.vertical) > 0) ? true : false;

            animationHandler.UpdateAnimatorValues(isWalk,inputSystem.isRun,inputSystem.vertical,inputSystem.horizontal);
        }

        private void PlayerRotate(Vector3 target)
        {
            if (Vector3.zero.Equals(target)) return;

            Quaternion tr = Quaternion.LookRotation(target);
            Quaternion targetRotation = Quaternion.Slerp(playerTransForm.rotation,tr,RotateSpeed*Time.deltaTime);
            playerTransForm.rotation = targetRotation;

        }
    }
}
