In this lesson, we will add a semi-automatic cannon to our game's hero that can be fired by clicking on the canvas.

We will use event listeners to detect when the user clicks on the canvas, and will use some basic math calculations to determine the direction and velocity of the cannonballs that are fired. This will give our hero the ability to engage in combat with enemies and obstacles, adding an exciting and challenging element to our game.

Additionally, we can expand and modify this feature in the future to add more complex behaviors and abilities to our hero, such as different types of weapons, firing modes, and reloading mechanics.
