How to change a variable from another script

Question

I have a gorgon enemy unit that has an invisible trigger space that acts like the gorgons vision. I want it to reduce the players speed. I have got it to detect the player, but the only way I could find to access the variable is as static which defeats the purpose of changing the value. Is there a better way to access variables? Also I have used a public static class general to access it but not change it.

why can't you change the variable if it is static? It should be possible.

If you want a different way you could use the ontrigger function maybe something like this

     PlayerScript myPlayerScript
 
 
     private void OnTriggerEnter(Collider other)
     {
         if (other.gameObject.CompareTag("Player"))
         {
             myPlayerScript = other.GetComponent<PlayerScript>();
 
             myPlayerScript.speed = 5;
         }
     }
 
 void OnTriggerExit(Collider other)
     {
         myPlayerScritpt.speed = 10;
     }

You do NOT need PlayerScript myPlayerScript

You can access the player's script from within the trigger functions. There's no need to create a member variable.

  private void OnTriggerEnter(Collider other)
  {
      if (other.CompareTag("Player"))
      {
          var player = other.GetComponent<PlayerScript>();
          player.speed = 5;
      }
  }

  void OnTriggerExit(Collider other)
  {
      if (other.CompareTag("Player"))
      {
          var player = other.GetComponent<PlayerScript>();
          player.speed = 10;
      }
  }
