Mob Spawner, choosing a random mob

Questions & Answers
1

I have a mob spawner script that has a timer int for how often an object spawns, variable for the prefab that I want to get spanwed and ints for how far and close the player must be for the script to disable.

But I would want to have multiple variable spots for diffrent objects and also having another variable for what % chance it has to be spawned. Any help for where to start from?

My current mob spawner scrpt:

var enemy: GameObject;
var spawnTime:float = 3f;
var player : Transform;
var CloseDistance = 3;					//Close Enough
var CloseEnough : boolean = false;
var FarDistance = 12;					//Far Enough
var FarEnough : boolean = false;
var isInInvoke : boolean = true;

private var thisTransform : Transform;

function Start(){
	thisTransform = transform;
	player = GameObject.FindWithTag("Player").transform;
}
  
InvokeRepeating ("Spawn", this.spawnTime, this.spawnTime);

function Spawn (){
	Instantiate (enemy, thisTransform.position, thisTransform.rotation);
}
 
function Update(){
	//Close Enough
	if(Vector2.Distance(transform.position, player.position) < CloseDistance){
		CloseEnough = true;
	} else {
		CloseEnough = false;
	}
	if (CloseEnough == true) {
		CancelInvoke("Spawn");
		isInInvoke=false;
	}
	if (CloseEnough == false && isInInvoke==false) {
		InvokeRepeating ("Spawn", this.spawnTime, this.spawnTime);
		isInInvoke=true;
	}
	
	//Far Enough and Close Enough
		if(Vector2.Distance(transform.position, player.position) > FarDistance){
		FarEnough = true;
	} else {
		FarEnough = false;
	}
	if (FarEnough == true) {
		CancelInvoke("Spawn");
		isInInvoke=false;
	}
	if (CloseEnough == false && isInInvoke==false) {
		InvokeRepeating ("Spawn", this.spawnTime, this.spawnTime);
		isInInvoke=true;
	}
}

try using random.Range

Here is some code I wrote to randomly spawn either a homing mine or normal mine, maybe this will help?

//Spawn a Mine Or Mine_Homing.   
if (Random.Range(0, 10) > 6) {

    if (iActive_Mines_Homing < iMax_No_Of_Mines_Homing) {
        subSpawn_Mine_Homing();
        
    } else {
        subSpawn_Mine();
    }
    
} else {
    
    if (iActive_Mines < iMax_No_Of_Mines) {
        subSpawn_Mine();
        
    } else {
        subSpawn_Mine_Homing();
    }
}
