One of the most common requirements of web applications is to be able to respond to user input, and in particular clicks (or touches). Continuing with our theme of element generation (and in some cases animation); this week’s challenge will be to create a basic whac-a-mole game.
The point of the game will be to click on highlighted elements to increase score. This can be as basic or as intricate as you wish it to be, but it should resemble the following diagram…
The green block represents the block a player must click in order to gain points. This means you will need logic to randomly select one of the possible blocks and highlight it. You also need to register user clicks and update the score “label”.
Hint: at times when you need to add many of the same kind of event to a variable amount of elements (in this case blocks); it is helpful and even efficient to use event delegation. You will need to use the setInterval() function or the setTimeout() function to create a predictable amount of time between each click or highlight.
