I have 2 spheres and a cube on screen.

I'm experimenting to make a 'left/right movement script' for the cube so that when I touch the left sphere, the cube moves left-wards and when I touch the right sphere, the cube moves right-wards.

I have 2 scripts. I have attached SphereLeft.cs to left sphere and SphereRight.cs to right sphere.

Any pointers on how to achieve this ?

Here we are just one script, assign it to the cube TargetSlideControl.cs

using UnityEngine;
using System.Collections;

public class TargetSlideControl : MonoBehaviour {

public int SPEED = 1;
public Transform leftTrigger;
public Transform rightTrigger;

// Use this for initialization
void Start () {


// Update is called once per frame
void Update () {
    // If Mobile
    if(Application.platform == RuntimePlatform.Android || Application.platform == RuntimePlatform.IPhonePlayer){
         if(Input.touchCount > 0) {
     }else if(Application.platform == RuntimePlatform.WindowsEditor){ // Else if Desktop
         if(Input.GetMouseButton(0)) {

private void checkTouch( Vector2 pos ) {
    Ray ray = Camera.main.ScreenPointToRay( pos );
    RaycastHit hit;
    if(Physics.Raycast(ray, out hit)){
        if(hit.collider.transform  == leftTrigger) {
        } else if(hit.collider.transform  == rightTrigger){

// Call Translate on this transform passing SPEED * Direction * deltaTime

public void SlideLeft() {       
    this.transform.Translate( SPEED * Vector3.left * Time.deltaTime, Space.World );

public void SlideRight() {
    this.transform.Translate( SPEED * Vector3.right * Time.deltaTime, Space.World );

Assign the spheres in the editor to the TargetSlideControl script:

  • \$\begingroup\$ Is it working in your editor/windows Desktop/Android phone ? I did what you said but the spheres are not receiving the touches on touching. I tried on an android phone, windows desktop. Not working. \$\endgroup\$ – Gissipi_453 Apr 5 '15 at 14:10
  • \$\begingroup\$ Sure it works! Have you dragged the spheres in the editor to leftTrigger and rightTrigger in the script? \$\endgroup\$ – SharpEdge Apr 5 '15 at 14:12
  • \$\begingroup\$ Sorry i forgot to tell you that the spheres need a collider applied \$\endgroup\$ – SharpEdge Apr 5 '15 at 14:31
  • \$\begingroup\$ No problem. I applied collider and ticked on 'Is Trigger' the cube. Accepted answer. \$\endgroup\$ – Gissipi_453 Apr 5 '15 at 14:47
