![]() ![]() We can then write callback functions to act on these events.Ī Kaboom game is made up of "scenes", which are like levels, or different parts and stages of a game. Kaboom makes good use of JavaScript's support for callbacks: instead of writing loops to read keyboard input and check if game objects have collided, Kaboom uses an event model that tells us when these events have happened. Extract the file on your computer, then add the sprites to the "Sprites" section in the Replit editor, and the sounds to the "Sounds" section. #Kuboom game zip fileIf you haven't already, download this zip file which contains all the sprites and sounds for the game. You can read up more about this interface here. #Kuboom game codeThese special folders take care of loading up assets, and all the necessary code to start scenes and direct the game. Besides the Space Invader icon, you'll notice a few special folders in the file tray, like "Code", "Sprites", and "Sounds". The Replit Kaboom interface is specialised for game-making. We'll use some of these features in our game to explore how Kaboom works. ![]() It has functionality to draw shapes and sprites (the images of characters and game elements) to the screen, get user input, play sounds, and more.

Here's how the game will look when we're done: We'll use Kaboom.js for the game engine, and we'll code it using Replit online IDE (Integrated Development Environment). ![]() In this tutorial, we'll build a space shooter game with a platformer feel. ![]()
