can you set boolean values using the input.getkeydown(keycode.(key))

hello, I am fairly new to this, and didn’t find another forum post for this, though I may not have done a query well enough to find the correct post. My code is below (found these through various searches).

using UnityEngine;
using System.Collections;
public float playerSpeed;
public float playerSpeedInitial = 1.5f;
public float playerSpeedMax = 10f;
public bool moving;
private bool moveForward;
private bool moveRight;
private bool moveBackward;
private bool moveLeft;
public class Movement : MonoBehaviour` {


	// Use this for initialization
	void Start () {
		

	}
	
	// Update is called once per frame
	void Update () {
		while (moving && playerSpeed != playerSpeedMax){
			playerSpeed = playerSpeedInitial + .15f * Time.deltaTime;
		}

		while (moving && playerSpeed = playerSpeedMax){
			playerSpeed = playerSpeedMax;
		}
          // below is the part that seems to be causing an issue, so I just wanted to
        //check if this would work... so basically, can this input change the Boolean 
     //value of moveForward, and if it can, do I have to modify this to make it work as 
   //it should? (cant remember how to make multi line comments, so sorry about that.)

		if (Input.GetKeyDown(KeyCode.W)){
			moveForward = true;
		}
		if (moveForward){
			transform.localPosition += transform.forward * playerSpeed;
			moving = true;
		}
		if (Input.GetKeyDown(KeyCode.D)){
			moveRight = true;
		}
		if (moveRight){
			transform.localPosition += transform.right * playerSpeed;
			moving = true;
		}
		if (Input.GetKeyDown(KeyCode.S)){
			moveBackward = true;
		}
		if (moveBackward){
			transform.localPosition += transform.backward * playerSpeed;
			moving = true;
		}
		if (Input.GetKeyDown(KeyCode.A)){
			moveLeft = true;
		}
		if (moveLeft){
			transform.localPosition += transform.left * playerSpeed;
			moving = true;
		}
		if !moving{
			playerSpeed = 0f;
		}

		}
	}
}

You can do this (forgive me for messing up your braces)

using UnityEngine;
using System.Collections;
public class Movement : MonoBehaviour
{
    public float playerSpeed;
    public float playerSpeedInitial = 1.5f;
    public float playerSpeedMax = 10f;
    public bool moving;
    private bool moveForward;
    private bool moveRight;
    private bool moveBackward;
    private bool moveLeft;

    // Use this for initialization
    void Start ()
    {

    }

    // Update is called once per frame
    void Update ()
    {
/*
        // the following could be an endless loop - uncomment it at your own risk (save scene first
        while (moving && playerSpeed != playerSpeedMax)
        {
            playerSpeed = playerSpeedInitial + .15f * Time.deltaTime;
        }
*/

/*
        // the following is an endless loop - un comment it at your own risk (save scene first
        while (moving && playerSpeed == playerSpeedMax)
        {
            playerSpeed = playerSpeedMax;
        }
    }
*/

        moveForward = (Input.GetKeyDown(KeyCode.W));
        moveRight = (Input.GetKeyDown(KeyCode.D));
        moveBackward = (Input.GetKeyDown(KeyCode.S));
        moveLeft = (Input.GetKeyDown(KeyCode.A));
        moving = (moveForward || moveRight || moveBackward || moveLeft);

        if (moveForward)
        {
            transform.localPosition += transform.forward * playerSpeed;
        }
        if (moveRight)
        {
            transform.localPosition += transform.right * playerSpeed;
        }
        if (moveBackward)
        {
            transform.localPosition += transform.backward * playerSpeed;
        }
        if (moveLeft)
        {
            transform.localPosition += transform.left * playerSpeed;
        }

        if (!moving)
        {
            playerSpeed = 0f;
        }
    }
}

or you can do this

using UnityEngine;
using System.Collections;
public class Movement : MonoBehaviour
{
    public float playerSpeed;
    public float playerSpeedInitial = 1.5f;
    public float playerSpeedMax = 10f;
    public bool moving;
    private bool moveForward;
    private bool moveRight;
    private bool moveBackward;
    private bool moveLeft;

    // Use this for initialization
    void Start ()
    {

    }

    public void OnMouseDown  ()
    {
        moveForward = (Input.GetKeyDown(KeyCode.W));
        moveRight = (Input.GetKeyDown(KeyCode.D));
        moveBackward = (Input.GetKeyDown(KeyCode.S));
        moveLeft = (Input.GetKeyDown(KeyCode.A));
        moving = (moveForward || moveRight || moveBackward || moveLeft);

        if (moveForward)
        {
            transform.localPosition += transform.forward * playerSpeed;
        }
        if (moveRight)
        {
            transform.localPosition += transform.right * playerSpeed;
        }
        if (moveBackward)
        {
            transform.localPosition += transform.backward * playerSpeed;
        }
        if (moveLeft)
        {
            transform.localPosition += transform.left * playerSpeed;
        }

        if (!moving)
        {
            playerSpeed = 0f;
        }
    }

    // Update is called once per frame
    void Update ()
    {
/*
        // the following could be an endless loop - uncomment it at your own risk (save scene first
        while (moving && playerSpeed != playerSpeedMax)
        {
            playerSpeed = playerSpeedInitial + .15f * Time.deltaTime;
        }
*/

/*
        // the following is an endless loop - uncomment it at your own risk (save scene first
        while (moving && playerSpeed == playerSpeedMax)
        {
            playerSpeed = playerSpeedMax;
        }
    }
*/
}

First of you had this for one of your while loops

while (moving && playerSpeed = playerSpeedMax)

this

playerSpeed = playerSpeedMax

is an assignment, not a comparison. You either wanted this

playerSpeed != playerSpeedMax

or this

playerSpeed == playerSpeedMax

Second, both while loops have the potential to be endless loops. I commented them out. You should only uncomment them (one at a time) after saving your scene.
