Question by Kaputnik88 · Jun 16, 2014 at 12:14 AM · javascriptinstantiateclass

How to create an instance of a class stored in another script

Hey there,

What I want to do is store class definitions in a script attached to gameobjectA, then at runtime instantiate these classes from a script attached to gameobjectB. How would I go about this? I'm working in UnityScript by the way.

You need to indicate if 'class definition' is derived from $$anonymous$$onoBehaviour.

Hey Robertbu, I'l try to be clearer. I have a class called Galaxy defined in script called classes.js which is attached to a gameObject, here is the definition:

 public class Galaxy{//$$anonymous$$ain gameworld class, creates and stores systems
     var syss : Array = [];//stores systems within the galaxy
     
     function Galaxy(){
         
         }
     function Init(me : Player,sls:Array){
         var i : int = Random.Range(1,5);//number of systems to be created
         var x : int = 0;//for iteration
         for (x = 0; x < i; x++){ //for number of systems
         var id : int = Random.Range(1,1000);//creating a random number as an ID(for debug purposes)
         var gal_position : Vector3;//stores system galaxy position
         gal_position=new Vector3(Random.Range(0,10),Random.Range(0,10),Random.Range(0,10));//sets galaxy position to random vector3 between 0 and 9
         //Debug.Log("CreatingSys:"+gal_position);
         var sec : Sys = Sys();//Creates instance of sector
         sec.Init(gal_position,me.gal_pos);
         this.syss.push(sec);//and adds it to the galaxy's system list
         sls.push(sec);
         //Debug.Log(x); 
         }
         //Debug.Log(gal_position);
         }
         
 }


I want to access this class definition from another script and construct the class from there like:

 var gl : Galaxy = classes.Galaxy();

The error im getting is that Galaxy is not a member of classes. Any assistance would be greatly appreciated, thank you!

Hmm apparently it works fine like this:

 var gl : Galaxy = Galaxy();

So Galaxy is within the scope of the other script, not sure how this is happening.
