CS8025 Parsing Error

Parsing errors are usually an issue with bracketing. In Monodevelop, you can place your cursor at an opening bracket '{' and it will find the matching closing bracket. In your case you close off the Start() function early, which leaves a bunch of code outside of a function but inside of the class. There are a few other problems in this code...some may be a result of how you pasted this code into UA. You want to use the 101/010 button, not the quote button.

 using UnityEngine;
 using System.Collections;
 
 public class PlayerBehaviour : MonoBehaviour {
     
     public Transform mesh;  
     public float forceFly;
     private Animator animatorPlayer;
     
     private float currentTimeToAnim;
     private bool inAnim;
     
     void Start () { 
         animatorPlayer = mesh.GetComponent<Animator>();  // Update is called once per frame void Update () {
     
         if(Input.GetMouseButtonDown(0)) {
             inAnim = true;     
         }
         
         if(inAnim){          
             currentTimeToAnim += Time.deltaTime;
             
             if(currentTimeToAnim > 0.4f) {
                 currentTimeToAnim = 0;
                 inAnim = false;
                 
             }
         }
     
         animatorPlayer.SetBool("callFly", inAnim);
     }
     
 }
