c# - Crouch Script/ Scaling transform from one side only -

im trying make crouching script there's wrong code, i've been stuck in here many hours , still don't know what's wrong.

im trying decrease height of player transform crouch, , increase stand up.

here's code:

public float crouchspeed; public float crouchwalkspeed; public bool iscrouching = false; public bool iscrouched = false;  void update () {      crouch();     iscrouchingvoid(); }  public void crouch()     {         if(input.getkeydown(keycode.leftcontrol) && isongroud)         {             iscrouched = !iscrouched;             iscrouching = true;         }     }      public void iscrouchingvoid()     {         if(!iscrouched)         {             if (iscrouching)             {                     vector3 temp = transform.localscale;                     temp.y -= crouchspeed / 60;                     temp.x = 1f;                     temp.z = 1f;                     transform.localscale = temp;                  if (temp.y <= 0.5f)                 {                     temp.y = 0.5f;                     iscrouching = false;                 }             }         }          else if(iscrouched)         {             if (iscrouching)             {                     vector3 temp = transform.localscale;                     temp.y += crouchspeed / 60;                     temp.x = 1f;                     temp.z = 1f;                     transform.localscale = temp;                  if (temp.y >= 1f)                 {                     temp.y = 1f;                     iscrouching = false;                 }             }         }     } 

thank you.

edit:

im using charactercontroller component using physics.capsulecast feature isn't option.

have tried using charactercontroller's height property?

you can reduce height in iscrouchingvoid() method instead of playing scale behaviour of crouching.
