Demo试玩（Kongregate既然也有广告时间了 --！）

操作步骤

1、下载素材

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;            }        }    }}
