Horror Crouch Script Help

I have a crouch script for a horror game, so when i press “c”, the player crouches close to the floor so it can hide under tables and beds. I need help with 3 problems that i can’t fix, in this order of priority:

1)Slow the crouch action (make it smother, because when i press “c” i crouch like in 1 second)

2)When i go under the table, I can’t stand up(that’s ok like that), but when i crouch out of it, i automatically stand up, still don’t know why…

3)I run and walk when crouching, i would like that this script disables that and crouch at a new slower speed than walking or running.

I would post here my Crouch script and my Player script, i would really apreciate any kind of help in any of the 3 points, please!

Crouch Script:

var crouchSpeed : float = 3; // crouching speed, not working...
    private var isCrouching : boolean = false;
    private var isInCrouchArea : boolean = false;

    function Start ()  

    isCrouching = false;

    function Update ()

    if (Input.GetKeyDown ("c"))

    isCrouching = true;
    speed = crouchSpeed;
    transform.position.y -= 3.5;      
    transform.localScale.y = 1;


    else if (!isInCrouchArea){

    isCrouching = false;
    transform.position.y += 5.5;            
    transform.localScale.y = 4.5;


    function OnTriggerStay( other : Collider )

        if ( other.gameObject.tag == "crouchArea"  )

           if ( !isInCrouchArea )
        isInCrouchArea = true;  


    function OnTriggerExit( other : Collider )

        if ( other.gameObject.tag == "crouchArea" )

    isInCrouchArea = false;   


    isCrouching = false;
    transform.position.y += 5.5;            
    transform.localScale.y = 4.5;

The Player Script:

so lets start with courch speed not working

   else if (Input.GetKey("c") && enableCrouch == true)
       speed = crouchSpeed;

you have in the first script however getkeydown

these are not the same

getkeydown triggers once get key is the state every frame

basically if you want a toggle for crouch where they click c to coruch you use getkeydown

if you want a hold to crouch you use getkey

the issue is it looks like your trying to use a toggle
if you are you need to get rid of that getkey


this is a toggle script version

//this is a toggle, whatever it was it's now the opposite when you press c
//if it's true so you were crouched, its now false, if you weren't
//its true so now you are

    crouched = !crouched;
    //were in the input loop still
    //now we know they press to crouch or stop doing it
    //we changed it so now we act on those changes
       speed = crouchspeed;
       //one way you could do this is to simply check if
       //crouched when trying to run 
       //an if(shift pressed && !crouched) then run
       //however this is more robust because later if you want
       //to swim or have a slow skill or something that 
       //prevents running or walking you can just again set to false these.
       CanRun = false;
       CanWalk = false;
       //now that these are set make sure in your run you do
       //if (shift held && CanRun) then run so you don't run if canrun is false

speed = normalspeed;
CanRun = true;
CanWalk = true;

as for how to crouch over time so its not instant look up lerping

basically instead of transform.position.y -= 3 or wahtever use lerp so you transition and move slowly to it instead of teleporting there.

vector3.lerp is the fucntion your looking for.

look up slerp and lerp (there nearly the same with some minor difference)
