操作步骤#

1、下载素材 http://pan.bai du.com/s/1gdkQz8v

2、新建三个GUITexture(Joystick)及一个Sprite(Nyan)

 

场景搭建#

3、创建背景及Platform(添加BoxCollider2D)

TouchControls.cs#

4、创建脚本 TouchControls.cs

using UnityEngine;
using System.Collections;

public class TouchControls : MonoBehaviour {
    //gui Textures
    public GUITexture guiLeft;
    public GUITexture guiRight;
    public GUITexture guiJump;


    //moement variables
    public float moveSpeed = 5f;
    public float jumpForce = 50f;
    public float maxJumpVelocity = 2f;

    private bool moveLeft, moveRight, doJump = false;

    // Use this for initialization
    void Start () {
    
    }
    
    // Update is called once per frame
    void Update () {
        //check to see if the screen is being touched
        if (Input.touchCount > 0)
        {
            Touch t = Input.GetTouch(0);//get the touch info
            //did the touch active just begin?
            if (t.phase == TouchPhase.Began)
            {
                //are we touching  the left arrow?
                if (guiLeft.HitTest(t.position, Camera.main))
                {
                    Debug.Log("Touching left Control");
                    moveLeft = true;
                }
                if (guiRight.HitTest(t.position, Camera.main))
                {
                    Debug.Log("Touching right Control");
                    moveRight = true;
                }
                if (guiJump.HitTest(t.position, Camera.main))
                {
                    Debug.Log("Touching jump Control");
                    doJump = true;
                }
            }
            //did the touch end?
            if (t.phase == TouchPhase.Ended)
            {
                doJump = moveLeft = moveRight = false;
                rigidbody2D.velocity = Vector2.zero;
            }
        }
        //is the left mouse button down?
        if (Input.GetMouseButtonDown(0))
        {
            if (guiLeft.HitTest(Input.mousePosition, Camera.main))
            {
                Debug.Log("touching left control");
                moveLeft = true;
            }
            if (guiRight.HitTest(Input.mousePosition, Camera.main))
            {
                Debug.Log("touching right control");
                 moveRight = true;
            }
            if (guiJump.HitTest(Input.mousePosition, Camera.main))
            {
                Debug.Log("touching jump control");
                doJump = true;
            }
        }
        if (Input.GetMouseButtonUp(0))
        {
            doJump = moveLeft = moveRight = false;
            rigidbody2D.velocity = Vector2.zero;
        }
    }

    void FixedUpdate()
    {
        if (moveLeft)
        {
            rigidbody2D.velocity = -Vector2.right * moveSpeed;
        }
        if (moveRight)
        {
            rigidbody2D.velocity = Vector2.right * moveSpeed;
        }
        if (doJump)
        {
            //// If we have not reached the maximum jump velocity, keep applying force.
            if (rigidbody2D.velocity.y < maxJumpVelocity)
            {
                rigidbody2D.AddForce(Vector2.up * jumpForce);
            }
            else
            {
                //otherwise stop jumping
                doJump = false;
            }
        }
    }
}
