Unity3D transform.position.x keeps setting to 0

Question

The weirdest thing keeps happening and I can not figure out why. Instead of just setting up like 20 different prefabs, I wanted to instatiate them in my code. I am making a Space Invaders C# game and I got the first row of invaders to spawn fine using the code found below. Literally no issues at all, and they move how I want them too as well. But as soon as I set up my second row the transform.position syntax that I used for the first row, suddenly does not apply and it just sets my transform.position.x to 0. I do have another class that MIGHT be the reason, but so far I have not found any solution to this problem. Thanks for help in advance.

Quaternion roto;
public Vector3 newPos;
public float addInvader
bool spawnInvader = true;
public GameObject invaders;
//

{
    newPos = transform.position;
    roto = transform.rotation;

    newPos2 = transform.position;
    roto2 = transform.rotation;

    if (addInvader <= 0f) 
    {
        SpawnInvaders ();
    }

    if (addInvader > 0f) 
    {
        SpawnInvaders ();
    }


    if (addInvader > 5f)
    {
        spawnInvader = false;
    }

    if (add2Invader <= 0f) 
    {
        //invaderSrow();
    }

Answer 1

in moveX1() you are using newX , is it possible you are sometimes calling moveX1 before firstMove ? if so then newX would be undefined and 0.

Answer 2

Figured it out. Added a newX = newPosX.x; line at the start of my moveX1() function :D thanks everyone who tried!
