GetComponent() - Is it possible to pass a string variable as name of the script?

Question

Newbie here, with excuses in advance if it was already answered or explained in some documents. Evidently I can't get it, even after reading severals posts and API's GetComponent() manual pages, I've solved nothing and I'm now more confused.

I have different Gameobjects with scripts on them all named like Cube1_MyScript, Cube2_MyScript, and so on.

I would like to access scripts passing their names as string variable to GetComponent(), if feasible. Something like this:

     public class Test : MonoBehaviour {       
     
           public Myscript script;
     
           void Update() {  [cut]

             objectname = hit.collider.name;
             scriptname = objectname+"_MyScript"; // In order to have Cube1_MyScript
     
             script = GameObject.Find(objectname).GetComponent<scriptname>();
             script.MyVarBool = true;
     
             }

This code obiouvsly doesn't work, just like several other that I've wrote, unfortunately I can't figure out alone if there's any way to get over this.

Thanks in advance for pointing out any info or help - will be very appreciated.

Check the docs.

The third listing for GetComponent is:

 Component GetComponent(string type);

Here is the example:

 using UnityEngine;
 using System.Collections;
 
 public class ExampleClass : MonoBehaviour {
     public HingeJoint hinge;
     void Example() {
         hinge = gameObject.GetComponent("HingeJoint") as HingeJoint;
         hinge.useSpring = false;
     }
 }

The docs can save you a lot of time and effort if you learn how to read them.

$$anonymous$$Y_STRING_VARIABLE has to be the name of a Component or Script Type, not the name of the object. And GetComponent needs to be called on the object with the component.

     public HingeJoint hinge;
  
     $$anonymous$$Y_STRING_VARIABLE = "Collider";
  
     void Example() {
     hinge = hit.GetComponent($$anonymous$$Y_STRING_VARIABLE) as HingeJoint;
     hinge.useSpring = false;
  
 }

 public class Test : $$anonymous$$onoBehaviour {       
  
       public $$anonymous$$yscript script;
  
       void Update() {
  
         [cut]
  
         objectname = hit.collider.name;
         scriptname = objectname+"_$$anonymous$$yScript"; // In order to have Cube1_$$anonymous$$yScript
  
         script = GameObject.Find(objectname).GetComponent(scriptname);
         script.$$anonymous$$yVarBool = true;
  
         }

I've already read the related API docs as stated in the initial question. The code above doesn't work.

After spending a few hours searching, I found the solution. Here is a small script that I made :)

This will create an array of Strings where you can write the names of the scripts you want to activate.

 var MyScriptNames: String[];
 
     function Start(){
     
     for(var i : int = 0; i < MyScriptNames.Length; i++)
         {
          (gameObject.GetComponent(MyScriptNames[i]) as MonoBehaviour).enabled = true;
          } 
     }
