如何在Unity3D中使GameObject跳转

我有一个2D游戏，其中GameObject（GO）移动到地板的右侧 . 我想让它跳起来 .

但是当我将 Character Controller 添加到我的GO并开始模拟时，它只是在左侧快速移动 . 可以't understand, what'错了 .

GO还包含 Rigidbody 和 Box Collider

public float jumpSpeed = 8.0f;
    public float gravity = 20.0f;
    private Vector3 moveDirection = Vector3.zero;

    void Start ()
    {
        player = (GameObject)this.gameObject;
    }

    void Update ()
    {
        // Move
        player.transform.position +=
            player.transform.right * speed * Time.deltaTime;

        // Jump    
        CharacterController controller = GetComponent<CharacterController>();
        if (controller.isGrounded)
        {
            moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0,
                                        Input.GetAxis("Vertical"));
            moveDirection = transform.TransformDirection(moveDirection);
            moveDirection *= speed;

            if(Input.GetKey(KeyCode.Space))
                moveDirection.y = jumpSpeed;
        }

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

    这是旧的，但在谷歌搜索时发现了这一点 .

    角色控制器不是为使用物理组件而设计的 . 拆下刚体和箱式对撞机 . 它使用模拟的胶囊对撞机进行检测 .

    同时从代码中删除以下内容，输入应该再次正常工作 .

    player.transform.position += player.transform.right * speed * time.deltaTime;

    那段代码导致你无意中移动 .

    您应该首先使用以下代码创建PlayerController类：

    public class PlayerController : MonoBehaviour {

    public Vector2 moving = new Vector2();

    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update () {

        moving.x = moving.y = 0;

        if (Input.GetKey ("right")) {
            moving.x = 1;
        } else if (Input.GetKey ("left")) {
            moving.x = -1;
        }

        if (Input.GetKey ("up")) {
            moving.y = 1;
        } else if (Input.GetKey ("down")) {
            moving.y = -1;
        }

    }
}

    然后使用以下代码创建Player类：

    using UnityEngine;
using System.Collections;

public class Player : MonoBehaviour {

    public float speed = 10f;
    public Vector2 maxVelocity = new Vector2(3, 5);
    public bool standing;
    public float jetSpeed = 15f;
    public float airSpeedMultiplier = .3f;
    public float jump=2f ;


    private PlayerController controller;

    void Start(){
        controller = GetComponent<PlayerController> ();

    }

    // Update is called once per frame
    void Update () {
        var forceX = 0f;
        var forceY = 0f;

        var absVelX = Mathf.Abs (rigidbody2D.velocity.x);
        var absVelY = Mathf.Abs (rigidbody2D.velocity.y);

        if (absVelY < .2f) {
            standing = true;
        } else {
            standing = false;
        }

        if (controller.moving.x != 0) {
            if(absVelX < maxVelocity.x){

                forceX = standing ? speed * controller.moving.x : (speed * controller.moving.x * airSpeedMultiplier);

                transform.localScale = new Vector3(forceX > 0 ? 1 : -1, 1, 1);
            }
        }

        if (controller.moving.y > 0) {
            if(absVelY < maxVelocity.y)
                forceY = jetSpeed * controller.moving.y;
        }

        rigidbody2D.AddForce (new Vector2 (forceX, forceY));
    if (Input.GetKey ("a")) {

            if (transform.localPosition.y < 1   ) 
                rigidbody2D.AddForce (new Vector2 (0, jump ));


                }

    }
}

    您可以使用箭头键飞行并使用“a”键跳转 . 你可以简单地改变它 .
