'other' is not a member of 'Object'?

Or use C#. C# doesn't break like this.

@robertbu: Thanks! that got rid of that error, but now it says: "BCWOO12: WARNING: "UnityEngine.Collision.other' is obsolete. Please use Collision.rigidbody, Collision.transform or Collision.collider ins$$anonymous$$d"

@Bored$$anonymous$$ormon: I am learning Javascript for class, so Im stuck with this atm

The error message tells you exactly what to do. Pick the statement as appropriate. In your case I would go with

 collisionInfo.rigidbody.Send$$anonymous$$essage(...);

But without seeing your exact set up its hard to tell if it actually matters which one you pick.

If your learning regular JavaScript for a class, the unityscript that unity has works differently. Just incase you didn't know!

@Bored$$anonymous$$ormon: Here is the other related Health script as the other is damage: (Unless you need more info)

 #pragma strict
 
 var maximumHealth = 100.0;
 var health = 100.0;
 var healthGUI : GUITexture;
 
 private var healthGUIWidth = 0.0;
 private var gotHitTimer = -1.0; 
 
 function Awake ()
 {
     healthGUIWidth = healthGUI.pixelInset.width;
 }
 
 function ApplyDamage (damage : float)
 {
     if(health < 0.0) //if not, gonna do something else
         return;
         
         health -= damage;//health $$anonymous$$us
         
         if(health < 0.0)
             Die();
 }
 
 function Die()//stops controlling character
 {
     var components : Component[]= GetComponentsInChildren($$anonymous$$onoBehaviour);
     for (var b in components) 
         {
             var p : $$anonymous$$onoBehaviour = b as $$anonymous$$onoBehaviour;
             if (p)
                 p.enabled = false;
         }
 }
 
 function LateUpdate ()//constantly updating GUI
 {
     UpdateGUI();
 }
 
 function UpdateGUI()
 {
     var healthFraction = $$anonymous$$athf.Clamp01(health / maximumHealth);
     healthGUI.pixelInset.x$$anonymous$$ax = healthGUI.pixelInset.x$$anonymous$$in + healthGUIWidth * healthFraction;
 }

@$$anonymous$$D_Reptile: Yea, Im learning Unity Javascript.
