step 1: take 3 plane
step 2:add cube and attach it to plane as a parent and set the tag name to them
step 3:add one cube to move and attach rigidbody
step 4:disp_pos=start_pos-initial_pos
step 5 :Script:-
using UnityEngine;
using System.Collections;
public class testproject : MonoBehaviour {
float _movespeed=5.0f;
private int _my_rand_val;
private Vector3 initial_pos =new Vector3(0f,0.904f,-10.03f);
private Vector3 start_pos =new Vector3(0f,1f,6.42f);
private Vector3 disp_pos =new Vector3(0f,0.1f,16.45f);
private Vector3 storeval;
public GameObject green;
public GameObject pink;
public GameObject blue;
// Use this for initialization
void Start () {
storeval=start_pos+disp_pos;
}
// Update is called once per frame
void Update () {
float _moveforward;
float _moveright;
_moveforward=Input.GetAxis("Vertical")*_movespeed*Time.deltaTime;
_moveright=Input.GetAxis("Horizontal")*_movespeed*Time.deltaTime;
transform.Translate(Vector3.forward*_moveforward);
transform.Translate(Vector3.right*_moveright);
}
void OnTriggerEnter(Collider other)
{
if(other.tag == "cube_collider")
{
print ("fine");
_rand_func();
Destroy(other.transform.parent.gameObject);
}
}
void _rand_func()
{
_my_rand_val=Random.Range(0, 3);
storeval=storeval+disp_pos;
if(_my_rand_val == 0)
{
Instantiate(green,storeval,Quaternion.identity);
}
if(_my_rand_val == 1)
{
Instantiate(blue,storeval,Quaternion.identity);
}
if(_my_rand_val == 2)
{
Instantiate(pink,storeval,Quaternion.identity);
}
}
}
