This is my class :

export class GameControlComponent implements OnInit {

  count = 0;
  @Output() num = new EventEmitter<number>();

  private intervalCall;


  ngOnInit(): void {
  }
  
  start(): void {
    this.intervalCall=setInterval(this.sendNumber, 1000); //works
  }
  stop(): void {
    clearInterval(this.intervalCall); //works
  }
  
  sendNumber(this:GameControlComponent){
    console.log(this)//windows
    this.num.emit(this.count); //this.num undefined
    this.count++; // this.count undefined
  }

}

Inside of my function sendNumber call by the setInterval function this corresponds to the windows instead of my component so I can't access my properties.

How to get this be equal to my component ?

Thanks guys !
