Unity3D 之3D游戏角色控制器运动

3D运动，绑定了人形控制器后的一个简单的运动方法。

using UnityEngine;
using System.Collections;

public class PlayerMove : MonoBehaviour {

    private CharacterController cc;
    private Animator animator;
    public float speed = 4;

    void Awake() {
        cc = this.GetComponent < CharacterController>();
        animator = this.GetComponent<Animator>();
    }
    
    
    // Update is called once per frame
    void Update () {
        float h = Input.GetAxis("Horizontal");
        float v = Input.GetAxis("Vertical");

        //按键的取值，以虚拟杆中的值为优先
        if (Joystick.h != 0 || Joystick.v != 0) {
            h = Joystick.h; 
            v = Joystick.v;
        }

        if (Mathf.Abs(h) > 0.1f || Mathf.Abs(v) > 0.1) {
            animator.SetBool("Walk", true);
            if (animator.GetCurrentAnimatorStateInfo(0).IsName("PlayerRun")) {
                Vector3 targetDir = new Vector3(h, 0, v);
                transform.LookAt(targetDir + transform.position);
                cc.SimpleMove(transform.forward * speed);
            }
        } else {
            animator.SetBool("Walk", false);
        }
    }
}

 复杂的运动，比如尝试着通过动力移动控制器。

public float speed = 6.0F;
    public float jumpSpeed = 8.0F;
    public float gravity = 20.0F;
    private Vector3 moveDirection = Vector3.zero; 
       //一个复杂的运动
        if (cc.isGrounded)
        {
            moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
            moveDirection = transform.TransformDirection(moveDirection);
            moveDirection *= speed;
            if (Input.GetButton("Jump"))
                moveDirection.y = jumpSpeed;

        }
        moveDirection.y -= gravity * Time.deltaTime;
        cc.Move(moveDirection * Time.deltaTime);

可以完成人物贴在地面上运动的效果。
