Overview

Right now, emojis are not interactive: the user can't click, drag, etc. with them. As @ian-craig said in #1:

No emoji overlay is complete without the ability to interact with them.

The most straightforward form of interaction I can imagine is adding a click handler. Consumers should be able to specify an onClick function that takes in an actor.

A few implementation detail notes:

• For accessibility, this means emojis should always be an interactive element (i.e. a <button> for this type of interaction). I think removing the tagName option is therefore reasonable.
• Let's make this a general events option with an onClick property, rather than a specific onClick option. We'll eventually want more event handlers than just clicks.

emojisplosion({
	events: {
		onClick(actor) {
			actor.update({
				opacity: 1,
				velocity: {
					y: actor.velocity.y - 1,
				},
			});
		},
	},
});

Additional Info

Consider this issue to be a precursor/lead-in to #1. Once we have this issue's infrastructure for an events option added, adding in drag handlers should be a natural next step.
