Using a String to populate GetComponent

Hi,

I need to dynamically create the 'Path' to a boolean value in an external script, but I get the following error:

MissingFieldException: Field 'SpawnAttackersAndDefenders.spawnModeIdentity' not found.

Here is the code so far:

 var spawnAttackersAndDefendersScript : SpawnAttackersAndDefenders;
 
 //The script that spawns the object this is attached to advises the name of the boolean to be changed
 var spawnModeIdentity : String;
 
 function Start(){
 
     spawnAttackersAndDefendersScript = GameObject.Find("Start").GetComponent(SpawnAttackersAndDefenders);
     
     spawnAttackersAndDefendersScript.spawnModeIdentity = true; //Script fails here
 }
 
 function OnTriggerEnter (other : Collider) {
     
     spawnAttackersAndDefendersScript.spawnModeIdentity = false; //Script fails here
 }

How do it correctly 'insert' the name of the boolean variable I am trying to target?

[UPDATE] To clarify, the var 'spawnModeIdentity' is NOT the real name of the boolean I am trying to target. It is simply a way of dynamically changing which boolean to target.

For example:

Script A has 3 Booleans:

var test1 = true;

var test2 = true;

var test3 = true;

Script B is designed to dynamically target only one of the Booleans in script A. Script A tells which Boolean Script B is to target using the following code:

scriptB.spawnModeIdentity = "test1"

This part is working fine.

From there I am trying to then correctly pass the new Boolean back to the relevant Boolean in Script A.

Thanks

Paul
