Creating Your First 3D Game: A Step-by-Step Guide

Are you ready to dive into the world of 3D game development but feeling overwhelmed by the complexities of the third dimension? Worry not, as we're here to guide you through the process of creating your very own 3D game from scratch. In this article, we'll focus on developing a third-person character that moves in relation to the camera, including essential features like jumping and model rotation based on movement direction.

Getting Started with Character Setup

To begin, let's establish the foundation of your game by setting up a character that can navigate the 3D environment seamlessly. In a new scene, create a kinematic body with a suitable collision shape. While you can use any model or mesh instance, we recommend starting with a character equipped with a capsule collision shape for smoother movement on various terrains.

Capsules vs. Cylinders: Capsules offer smooth motion on slopes and corners, ideal for your character to navigate through the game world effortlessly. On the other hand, cylinders provide stability on edges but may result in less smooth movement, especially on uneven surfaces.

Implementing Camera Functionality

In 3D game development, a camera plays a vital role in rendering the game world effectively. To ensure your character moves relative to the camera, add a spring arm node to the player, with the camera as its child. This setup allows the camera to follow and orbit the character at a set distance, preventing it from colliding with obstacles within the game environment.

Coding Character Movement

Moving on to the coding aspect, we'll equip our character with the ability to move, jump, and interact within the game space. By adding a script to the kinematic body node, you gain access to functions like move_and_slide_with_snap for controlled movement on slopes and precise handling of character actions.

Enhancing Player and Camera Interaction

To further enhance the player experience, we focus on synchronizing camera movements with the character's actions. By adjusting the spring arm properties and implementing a script to control camera rotation, you can offer players a dynamic perspective as they navigate through the game world.

Bringing It All Together

By integrating the character's model rotation based on movement direction, your 3D platformer character now comes to life with fluid movements and interactive camera functionality. This comprehensive setup sets the stage for a captivating gaming experience.
