Extending Phaser functions

[Zampano]

Hey everyone,

I want to attach some additional code to Phaser.Tween.start.

I realize I could do

Phaser.Tween.prototype.start_custom = function () {
	console.log("Custom Code");
	Phaser.Tween.prototype.start.call();
}

But couldn't I also do it without creating a separate function? I can't find anything really helpful on it and although I realize it's pretty basic, I have no idea on how to actually do it

Any help is greatly appreciated.

One is just to copy and modify the original function body, then overwrite the function:

Phaser.Tween.prototype.start = function () {
  // ...
};

Another is to save the original and call it from the new function:

var tweenStart = Phaser.Tween.prototype.start;

Phaser.Tween.prototype.start = function () {
  // special code ...
  tweenStart.call(this);
  // special code ...
};

Okay, I didn't want to do the first in case there were any updates or fixes. The second one will do fine, thank you!
