[C#] Need help with synchronization mutexes in hook EndScene

[Ferroks]

Please help with synchronization mutexes in sample hook EndScene for D3

int j = 0;
                        while (true && j<=5)
                        {
                            /* Мы дождались конца отрисовки кадра и вызова Present в игре */
                            if (eventPresentInvoked.WaitOne(_executorTimeout))
                            {
                                //This code works
                                //Clear();
                                //AppendLine("push 0");
                                //AppendLine("push {0}", memCaption.BaseAddress);
                                //AppendLine("push {0}", memText.BaseAddress);
                                //AppendLine("push 0");
                                //AppendLine("call {0}", _memory["user32.dll"]["MessageBoxW"].BaseAddress);
                                //AppendLine("retn");
                                //_callee.Write(_callee.BaseAddress + 4);
                                //_memory.Assembly.Inject(_asm.ToString(), _callee.BaseAddress + 4);
                                //Console.WriteLine("Кадр");
                                
                                //This code does not work as you want. Need to operate at the end of each frame.
                                var player = ActorCommonDataHelper.GetLocalAcd();
                                var hz = ActorHelper.GetLocalActor();
                                var hp = player.x188_Hitpoints;
                                Console.WriteLine(hp);
                                
                                /* Говорим нашему исполнителю что мы впихнули код и он может его выполнить */
                                eventInjectedCode.Set();
                                eventPresentInvoked.WaitOne(_executorTimeout);
                                j++;
                            }
                            else
                            {
                                Console.WriteLine("Превышен таймаут завершения отрисовки кадра ({0} сек)!", _executorTimeout);
                            }
                        }

my question is incorrect or incomprehensible or difficult?

to see and test the code, a lot of action is not necessary.
Need ustavnovlenaya D3, everything else in the example there. Start debugging.
