totally confused with GetComponent

[anon26258571]

sorry guys I am a total idiot... but if i wanna make it so that when object registers a collision, it changes the value of a public variable "HitPoints" on a script attached to another object called "Health"... how can I do that? likewise... could I use this the same way to change to "Use Gravity" variable from true to false on an attached rigidbody instead of changing the hitpoints on the health script?

Yes you can.

You need to instantiate the class you keep the public variable "health" into an object and store it into where you need it, like this:

public class MyHealthClass : MonoBehaviour
{
   public float Health;

   void Start()
   {
      Health = 100;
   }

   void Update()
   {
       //Nothing here, boring script waiting for work
   }

   //Adds value to current health
   public void ChangeHP(float changeAmount)
   {
      Health += changeAmount;
   }
}

public class myBoxThingyThatCanCollide : MonoBehaviour
{
    MyHealthClass myObjectReference;

    void Start()
    {
        myObjectReference = new MyHealthClass();
    }

    void Update()
    {

    }

    //Requires a characterController
    void OnControllerColliderHit(ControllerColliderHit cch)
    {
        //Subtracts 10 life on collision with anything
        myObjectReference.changeHP(-10);
    }
}

I didn't check a compile so please forgive any syntax error, the most of it should be ok
