Hi! I have been running into a problem with the Input.onDown event. Once my code is inside the create function and I add the SayHi function to the onDown event it throws a error. Sample code: class GameInitializer { game: Phaser.Game; constructor() { this.game = new Phaser.Game(window.innerWidth, window.innerHeight, Phaser.AUTO, 'content', { create: this.create }); } create() { console.log(typeof (this.SayHi));//undefined this.game.input.onDown.add(this.SayHi);//Uncaught Error: Phaser.Signal: listener is a required param of add() and should be a Function. } SayHi() { console.log("hi"); }}window.onload = () => { var game = new GameInitializer();};I have tried to figure out what the problem is and noticed that this.SayHi is undefined but have no clue why that is. So my question is how should I go about and fix this? Thanks in advance.
