Feature Request: Make all functions declared in a GameObject methods of the GameObject

[jcollard]

I think it would be convenient to have all of the functions declared within a GameObject be methods of the GameObject. Currently, the start and update functions are actually methods of the GameObject. However, all other functions are methods of the Window. Here is a simple example demonstrating the current functionality:

 // It would be nice to have functions become methods of the
 // object. I am using a self = this hack and adding member
 // variables which also is slightly broken.

// called once when the game starts
function start() {
 this.hp = 8;
}

// called every frame
function update() {
 // This is a method of the GameObject
 if (isKey('q'))
 say(`I have ${this.hp} hp`);
 
 if (isKey('w'))
 notAMethod();
 
 if (isKey('e'))
 pythonStyleMethod(this);
 
 
}

function notAMethod() {
 // `this` is the Window object
 say(`I have ${this.hp} hp`);
}

function pythonStyleMethod(self) {
 say(`I have ${self.hp} hp`);
}

It isn't completely necessary to add this as there are work arounds. For example, in the start method you can declare a method and forward it to a function. At that point, the this keyword will work in the context of update. BUT it will not work in the context of any other methods. In the example below, there is a workaround to declare a GameObject variable self which can be used throughout all of the functions. It feels a little bit hacky but could potentially be the way Code train handles "public / private" methods and fields.

let self;

function start() {
 this.hp = 8;
 this.addMethod = notAMethod;
 self = this; 
}


function notAMethod() {
 // `this` is the Window object
 say(`I have ${this.hp} hp`);
}

Thanks for the suggestion, I agree that declared functions should become methods of the GameObject. I'll see if I can restructure GameObject handling to make this work.
