Assigning variables to GameObjects

Question

I am making a script to call variables from the object which hits the targets to calculate force. But, I was wondering if there was a simple way to make a private variable to that GameObject and later to be able to access it like you can do with transform.

In tranform you can do

terrain.transform or this.transform I want to be able to access a variable like that be able to do. var bulletWeight : float = GameObject.Find("Bullet").weight; bullet.mass etc.

Is there a way to do this? Without making a script to assign the value and then accessing that script value and calling it from there? I rather not do it this way unless I have too.

You cannot access private variables directly from other scripts at all. You would need getter/setter functions...

Public variables can be accessed by:

 gameObject.GetComponent(ScriptName).VariableName;    //UnityScript
 //or
 gameObject.GetComponent<ScriptName>().VariableName;    //C#

Also, GameObject.Find() should only ever be called in Start() or Awake(). Don't call it repeatedly, since it is quite expensive.

You'll have to do it via attached script classes (which can be attached as 'components.') Even the basic Gameobject is class that is a collection of other classes and structs (such as transform.)

Simple class example (c#)

 using UnityEngine;
 using System.Collections;
 
 public class bullet : MonoBehaviour {
  
        float weight;
        float speed;
 
 }
