It is my other code

I have 7 error about CS0246. I used all namespace whatever I can use but it does not work. I checked the briket and semicolon all of them but i am not sure why i get error. I used **

using UnityEngine;
using UnityEngine.Video; 
using UnityEngine.UI;
using UnityEditor;
using System.Diagnostics;  

** Those namespace but it does not work please help me............ **Please note the parenthesis which are causing the issue I have labelled Error Parethesis however I am not entirely sure these are causing the overall issue.

CodePudding user response：

Try to put a space between the using System.Diagnostics; and the monobehaviour and also make sure it has the same name as the script file you created.

Reading the error messages:

Should this be PlayerMovement rather than PlayMovement?
