Question My Camera is moving up and down, but not left and right

Ok, so I was making an first person game, and everything was working fine, until it crashed and i lost all my progress, so I made a new one. Now I inserted the same script into the new game. Now i cant rotate the camera from side to side. I can still move, jump, and look up and down.

What i tried:
-increasing the x look limit
-changing the look speed
-making the capsule (body) a child of the main camera.

I apologize if this is a no-brainer, im new to unity.
Here is the code

Code (csharp):

1.  
2.         characterController.Move(moveDirection * Time.deltaTime);
3.  
4.         if (canMove)
5.         {
6.             rotationX += -Input.GetAxis("Mouse Y") * lookSpeed;
7.             rotationX = Mathf.Clamp(rotationX, -lookXLimit, lookXLimit);
8.             playerCamera.transform.localRotation = Quaternion.Euler(rotationX, 0, 0);
9.             transform.rotation *= Quaternion.Euler(0, Input.GetAxis("Mouse X") * lookSpeed, 0);
10.         }
11.  

 

dang it. I messed up. Sorry it looks like only mods can delete posts. dont reply. i figured it out
if anyone comes to this thread with the same problem, put the script in your empty player object, not your camera
apologies

 

Details like this are critical... thanks for coming back.

If you just need an FPS controller, here is a super-basic starter prototype FPS based on Character Controller (BasicFPCC):

That one has run, walk, jump, slide, crouch... it's crazy-nutty!!
