Hi. Im writing a script for my player of a 2d style game, but i have some problems. I want to make a gameplay like super mario, that when i hold left arrow it rotates to the left side and with no extra rotating continues to going on left direction and same for the right direction.
Now i can move left and right. My camera is attached to my player and follows it only on x axis and everything looks good, but when i rotate left and hold left arrow it moves really fast, i tried to add Time.deltaTime but it didn't changed . Im really confused . I need some help so plssss help me with this rotation problem and also i want my camera to stop rotating when player rotates cuz they are both parented to each other . so we got 2 prob :

1. rotation doesnt work well and it speeds up !!
2. need to add something to prevent rotating the camera when the player rotates...

here is my code:

var playerSpeed : int;
var jumpHeight  : int;

function Update () 
{
    // getting the transform of the main camera and put it in a new var.
    var cameraTransform = Camera.main.transform;  

    // making the camera child of the player .
    cameraTransform.parent = transform;

    amtToMove = playerSpeed * Input.GetAxis("Horizontal") * Time.deltaTime;

    transform.Translate(Vector3.right * amtToMove);

    //------------------------------------------------------------------------

    //3- player rotation...! 

    if (Input.GetKey("left") || Input.GetKey("a"))
    {
        this.gameObject.transform.rotation = Quaternion.Euler(0,180,0);
        transform.Translate(Vector3.right );
    }      
    if (Input.GetKey("right") || Input.GetKey("d"))
    {
        this.gameObject.transform.rotation = Quaternion.Euler(0,0,0);        
    }

    //--------------------------------------------------------------------------

    //4- player jump

    // player can countinusly jump when you hold the up button. if its transform position in y axis is equal to 0.73(on the ground)
    if ( (Input.GetKey("up") || Input.GetKey("w") )  && transform.position.y == 0.73)                                      
    {
        amtToJump = jumpHeight + Time.smoothDeltaTime ;
        transform.Translate(Vector3.up * amtToJump );
    }
}


//5- camera follow

// this function lets the camera be parented to the player but prevent it from moving along the y axis when the player jumps.
function LateUpdate() 
{
    Camera.main.transform.position.y = 2.77;  
}
