Welcome back! In this article, we will explore how to build a space shooter game using Open AI. The game, called X Playground, allows you to control a spaceship, move it left and right, fire bullets, and destroy enemies. Let’s dive in!
To get started, you can visit the Open AI Codex JavaScript sandbox. In this game, we will use images to display the background, spaceship, bullets, and enemies. Make sure to have these images ready.
First, let’s set the background image and paste the image link. Next, we will display the spaceship image and adjust its size to make it smaller.
Now, we need to add functionality to move the spaceship. We can achieve this by making the spaceship image move left or right with mouse movement. Keep the y-coordinate constant and set the x-coordinate to the mouse’s x-coordinate.
Great! Now our spaceship can move left and right with the cursor. Let’s move on to firing bullets. When the spacebar key is pressed, we will display the bullet image at the spaceship’s location and move it upwards to simulate firing bullets.
Try pressing the spacebar to fire bullets. It’s working!
Next, we need to add enemies to the game. Paste the image link for the enemy image. We will create a new enemy every 4 seconds at a random x-coordinate and y-coordinate of zero. The enemies will move down the screen.
Wow! Open AI figured out that the enemy image should move down on its own. However, the speed is too fast. You can adjust the speed by changing the code.
Now, let’s add collision detection. This will allow us to destroy enemies when a bullet touches them. When the bullet image overlaps with the enemy image, remove the enemy image and increase the score by one.
Our code is generated! Let’s try it out. Move the spaceship with the cursor, press the spacebar to fire bullets, and destroy the enemies. The score will increase with each enemy destroyed. Amazing!
To make the game more challenging, you can increase the number of enemies created. Simply change the code to create a new enemy every 2 seconds.
Now, let’s add some sound effects to the game. Copy the provided code and open Visual Studio Code. Create an HTML file and add a script tag. Paste the JavaScript code inside the script tag. Make sure to have the bullet and destroyed sound effect files. Add the code to play the sound effects when firing bullets and destroying enemies.
Launch the game with a live server. Now, we have a fully functional space shooter game with sound effects! The spaceship can move left and right, fire bullets with sound effects, and destroy enemies. The score updates as enemies are destroyed.
You can further enhance the game by adding a game over condition, such as when an enemy reaches the bottom. For now, we have a simple space shooter game built using Open AI. Give it a try on Open AI’s Codex Playground!
