unity3d - How to Unity create your own button to control the player on mobile device -

i not sure how ,my goal create button control player on plane mobile touch devices.i created button trying make control player failing here player c# script

using unityengine; using system.collections;  public class playermovement : monobehaviour  {    public float speed = 500f, jumpheight = 500f;    transform mytrans;    rigidbody2d mybody;    vector2 movement;//used temp holder variable before applying velocity    bool isgrounded = true;      void start ()     {        mytrans = this.transform;        mybody = this.getcomponent<rigidbody2d>() ;    }     void update ()     {        //check if player grounded or not        isgrounded = physics2d.linecast(mytrans.position,                                        gameobject.find(this.name+"/tag_ground").transform.position,                                        layermask.nametolayer("player"));         //just visualization, not needed gameplay        debug.drawline (mytrans.position,                     gameobject.find(this.name+"/tag_ground").transform.position,                     color.red);          //works keyboards , joysticks        #if !unity_android && !unity_iphone && !unity_blackberry && !unity_winrt        move (input.getaxisraw("horizontal"));        if (input.getbuttondown ("jump"))           jump ();        #endif    }    //    //separate move , jump can called externally touchbuttons    //    public void move(float horizontal_input)    {        movement = mybody.velocity;         if(isgrounded)//we can move left , right if on ground            movement.x = horizontal_input * speed * time.deltatime;         //apply movement player        mybody.velocity = movement;    }    public void jump()//we can jump if on ground    {        if(isgrounded)            mybody.velocity += jumpheight * vector2.up * time.deltatime;    } } 

here touch logic script

using unityengine; using system.collections;  public class touchlogicv2 : monobehaviour { public static int currtouch = 0;//so other scripts can know touch on screen [hideininspector] public int touch2watch = 64; private new guitexture guitexture; public virtual void update()//if child class uses update, must call base.update(); functionality {     //is there touch on screen?     if(input.touches.length <= 0)     {         onnotouches();     }     else //if there touch     {         //loop through the touches on screen         for(int = 0; < input.touchcount; i++)         {             currtouch = i;             //executes code current touch (i) on screen             if(this.guitexture != null && (this.guitexture.hittest(input.gettouch(i).position)))             {                 //if current touch hits our guitexture, run code                 if(input.gettouch(i).phase == touchphase.began)                 {                     ontouchbegan();                     touch2watch = currtouch;                 }                 if(input.gettouch(i).phase == touchphase.ended)                 {                     ontouchended();                 }                 if(input.gettouch(i).phase == touchphase.moved)                 {                     ontouchmoved();                 }                 if(input.gettouch(i).phase == touchphase.stationary)                 {                     ontouchstayed();                 }             }             //outside doesn't require touch on guitexture             switch(input.gettouch(i).phase)             {             case touchphase.began:                 ontouchbegananywhere();                 break;             case touchphase.ended:                 ontouchendedanywhere();                 break;             case touchphase.moved:                 ontouchmovedanywhere();                 break;             case touchphase.stationary:                 ontouchstayedanywhere();                 break;             }         }     } } //the default functions, define happen if child doesn't override these functions public virtual void onnotouches(){} public virtual void ontouchbegan(){print (name + " not using ontouchbegan");} public virtual void ontouchended(){} public virtual void ontouchmoved(){} public virtual void ontouchstayed(){} public virtual void ontouchbegananywhere(){} public virtual void ontouchendedanywhere(){} public virtual void ontouchmovedanywhere(){} public virtual void ontouchstayedanywhere(){}

i following touchlogic tuts struggling move player on mobile.any examples on touch input welcomed give me links examples.thanks
