Creating an endless runner game in Unity from scratch

Key takeaways:

• Learn Unity fundamentals by creating an endless runner game featuring procedural generation and player control.

• Implement core gameplay elements like platform generation, collision detection, and player movement.

• Use optional enhancements such as collectible coins, dynamic animations, and a dash ability for a richer gameplay experience.

• Add “Game Over” mechanics to complete the game flow and create an engaging, challenge-filled journey for players.

An endless runner game is a genre of video game where the character moves forward continually in a procedurally generated environment. The objective is to navigate obstacles, collect items, and achieve a high score by lasting as long as possible. The game ends when the character hits an obstacle or falls off the platform. Some popular games like this are “Temple Run” and “Subway Surfers.”

Creating an endless runner game in Unity is a fantastic way to learn game development fundamentals while building something fun and interactive. This genre is ideal for beginners as it introduces core concepts like procedural generation, collision detection, and player control in an approachable way.

Now, this tutorial takes you through every step, from initial setup to implementing controls, procedural level generation, and more. Let’s jump in and start building your very own Endless Runner adventure!

Step 1: Setting up the scene

The first step in creating any game is to initialize the project and set up the scene. The scene of an endless runner game should include a platform, a player, and obstacles to tackle.

Step 2: Platform management

In endless runner games, platforms stretch infinitely. However, opting for a single lengthy platform would divert from the endless runner concept.

Step 3: Player controls

After setting up the scene and implementing the logic of platform generation, the next step is to control the player's movement. The forward movement of the endless runner game is usually continuous, and the player can move sideways.

Step 4: Collision and events trigger

We have seen that when the player collides with an obstacle, an event is triggered. This event could reduce the player’s health. In our case, the game ends upon collision. You need to implement a final “Game Over” screen that will be displayed on collision.

Step 5: Taking your game to the next level (Optional)

To add an extra layer of excitement to your endless runner game, consider implementing some optional enhancements that can make the gameplay more dynamic and enjoyable.

• Collectible coins: Increase the challenge of your game by incorporating collectible coins. Players can aim to collect these coins as they run, adding an element of strategy and reward. The collected coins could contribute to a player’s score or unlock special features, encouraging players to strive for higher scores.

• Dynamic animations: By adding animations to the player character, obstacles, and the game environment, you can create a more immersive experience. Animations can emphasize movement, speed, and interactions, enhancing the overall visual appeal and engagement.

• Humanoid player with dash ability: For a more relatable character, consider introducing a humanoid player with distinct animations. To inject excitement, implement a dash ability that grants the player a burst of speed and temporary invulnerability. This strategic mechanic provides players with a way to navigate challenging sections and adds an element of skill to the game.

These enhancements are entirely optional, but they can significantly enrich your endless runner game. By integrating these features, you can create a more captivating and entertaining experience for players, encouraging them to explore different gameplay strategies and achieve higher scores.
