Now drag and drop all the sprite files (image files) into the 'sprites' folder. In the Kaboom editor, click the 'Files' icon in the sidebar. It already has some code in it, but we'll replace that.ĭownload this archive of sprites and asset files we'll need for the game, and unzip them on your computer. Name it something like 'Space Invaders', and click 'Create Repl'.Īfter the repl has booted up, you should see a main.js file under the 'Scenes' section. Head over to Replit and create a new repl, using 'Kaboom' as the template. When the aliens reach the bottom of the screen, the game is immediately over, as the alien invasion was a success! To win, the player has to destroy all the aliens before they reach the bottom of the screen. Players have three lives, and the game ends when they run out of lives. If the player gets shot, they lose a life. The aliens in the bottom row can shoot downwards towards the player. Shooting an alien will destroy it and score points for the player. In this way, the aliens get closer and closer to the player. Once the aliens reach the end of the screen, they move down one row and start moving in the opposite direction. The player moves left and right along the bottom of the screen and shoots at the aliens from below. Space Invaders features alien enemies that move across the screen from one side to the other in a grid formation. Let's make our own version using Kaboom and Replit. Of course, Space Invaders was such a popular game, there were many clones and variations.

Space Invaders is pretty embedded in pop culture these days, and you might even find Space Invaders mosaic and graffiti on the streets! It was a great success, and meant that people could play Space Invaders on their home systems, instead of on an arcade machine. Later, Atari released a clone of Space Invaders on the Atari 2600 home system. It was an absolute monster hit, making nearly $4 billion in sales (that's the equivalent of over $13 billion today)! Space Invaders is a classic shoot 'em up arcade game created by Taito Corporation in Japan way back in 1978.
