    Hello,

    I'm new in Unity. I want to change scale (size i.e. width , height ) during run-time of a gameobject. How can I possibly do that? I've used localscale function it but didn't work properly. May be I didn't use it properly :( . Any help ?

    Thanks in advance,
    _Masudias

    I want a plane fit in any size of screen .

    I'm not sure but this code may do like this
    previous object is enlarged by 0.1

    I've tried this code :

    But it won't work !
    The Gameobject became very large than it was expected !

    I'm such a noob sire :(
    Help me out !

    Thanks

    Use this for once
    Code (CSharp):
    1.  
    2. using UnityEngine;
    3. using System.Collections;
    4.  
    5. public class NewBehaviourScript : MonoBehaviour {
    6.      GameObject rotater;
    7.  
    8.       void Start () {
    9.        rotater = GameObject.Find("Cube");
    10.        }
    11.     public void btnChangeHeight() {
    12.       rotater.gameObject.transform.localScale += newVector3(0,50,0);
    13.     }
    14. }
    15.  
    While button is pressed (repeatButton)
    Code (CSharp):
    1.  
    2. using UnityEngine;
    3. using System.Collections;
    4.  
    5. public class NewBehaviourScript : MonoBehaviour {
    6.  
    7.  
    8.         GameObject rotater;
    9.  
    10.         void Start () {
    11.                rotater = GameObject.Find("Cube")
    12.          }
    13.         void OnGUI() {
    14.                 if (GUI.RepeatButton (new Rect (40, 60, 70, 21), "Height")) {
    15.                 rotater.gameObject.transform.localScale += new Vector3(0,1,0);
    16.                 }
    17.          }
    18. }
    19.

    it only requires a few lines of code

    Noob here, I think this is the easiest method:

    Define the rigidbody of your object in Start(), like this:
    playerRb = GetComponent<Rigidbody>();

    Then put this in an if loop. Adjust float size as needed:
    playerRb.transform.localScale += new Vector3(0.05f, 0.05f, 0.05f);

    That is definitely not the easiest way, using the rigid body is unnecessary. Instead, you can just write
    transform.localScale += new Vector3(0.05f, 0.05f, 0.05f);

    You named a variable of your own "Vector3". Don't do that, rename that variable.
