While/Do loop problem(for all I know its something else)

Question

I thought I had an idea of what I was doing, but I obviously don't. I am trying to get some monsters (Clizy) to instantiate in around the map, I just need them not to appear in the center. I also need them to randomly instantiate (but not in the middle) I worked except when both else statements were true. I know this probably won't make any sense, but if someone can point out my error, or another way to do this I would be very thankful. my error is this: .js(25,131): BCE0044: expecting ), found 'Quaternion'.

 function DecideXaxis (X : int, XVal : int){
     if(X <=1){
            XVal = Random.Range(-9, 15);
        } else if (X <= 2){
            XVal = Random.Range(-9, 90);
        }else XVal = Random.Range(75, 90);
        return XVal;
 }
 function DecideZaxis (Z : int, ZVal : int){
     if(Z <=1){
            ZVal = Random.Range(-9, 15);
        } else if (Z <= 2){
            ZVal = Random.Range(-9, 90);
        }else ZVal = Random.Range(75, 90);
        return ZVal;
 }
 var Clizy : GameObject; 
 var lightObject : Light; 
 function OnTriggerStay (other : Collider) {
        if(lightObject.enabled == true){ 
            if (other.CompareTag ("Respawn")) {
                    Destroy (other.gameObject); 
                    yield WaitForSeconds (1);
                    do {
                        Instantiate (Clizy, Vector3(DecideXaxis(Random.Range(1,3), 0),-16,DecideZaxis(Random.Range(1,3))) Quaternion.identity);
                    } while(Z > 2 && X > 2) {
                        Instantiate (Clizy, Vector3(DecideXaxis(Random.Range(1,3), 0),-16,DecideZaxis(Random.Range(1,3))) Quaternion.identity); 
                    }
         }
     }
 }

I believe you're missing a comma following the position and before the quaternion; what you have is

 Instantiate (Clizy, Vector3(DecideXaxis(Random.Range(1,3), 0),-16,DecideZaxis(Random.Range(1,3))) Quaternion.identity);

when you're after

 Instantiate (Clizy, Vector3(DecideXaxis(Random.Range(1,3), 0),-16,DecideZaxis(Random.Range(1,3))), Quaternion.identity);

Because there's no comma, it's giving you the error because it's assuming that's the end of the parameters you're passing in (position/rotation are optional in Instantiate()).

The format for do/while is

 do {
     // something
 }
 while (condition);

You appear to be trying to combine a standard while loop with a do/while loop, which isn't possible. However that would be an infinite loop anyway, since you never change Z or X inside the loop.

thanks guys you were a great help, not that anyone will need to use this but the finished code looks like this:

 function DecideXaxis (X : int, XVal : int){
     if(X <=1){
            XVal = Random.Range(-9, 90);
        }else if (X  <= 2){
            XVal = -10;
        }else if (X <= 3) {
            XVal = Random.Range(-9, 90);
        }else if (X  <= 4){
            XVal = 80;
        }
        return XVal;
 }
 function DecideZaxis (Z : int, ZVal : int){
     if(Z <=1){
            ZVal = 60;
        }else if (Z  <= 2){
            ZVal = Random.Range(-35, 65);
        }else if (ZVal <= 3) {
            ZVal = -30;
        }else if (Z  <= 4){
            ZVal = Random.Range(-35, 65);
        }
        return ZVal;
 }
 var Clizy : GameObject; // monster prefab
 var lightObject : Light; //light that activates the forcefeild
 function OnTriggerStay (other : Collider) {
     if(lightObject.enabled == true){ // if the light is on
            if (other.CompareTag ("Respawn")) {
                Destroy (other.gameObject); // destroy it
                yield WaitForSeconds (1.5);
                var number : int;
                number = Random.Range(1,4);
                Instantiate (Clizy, Vector3(DecideXaxis(number, 0),-16,DecideZaxis(number, 0)), Quaternion.identity);
         }
     }
 
 }

so if anyone is looking on this post looking for the actual answer to this question, it is here, but I couldn't have done it without you guys!! I was doing it all wrong anyway
