Creating a 3D Character Controller in Unity: A Step-by-Step Guide

Unity is a versatile game development platform that allows creators to bring their visions to life. In this first part of a three-part series, we will focus on building a 3D character controller that enables smooth and intuitive movement. Subsequent parts will delve into implementing an orbiting camera and establishing character movement relative to the camera direction.

Setting Up the Scene

To begin, we start in a blank Unity project. The end product of this series will be available on Patreon, but you can follow along independently. Let's kick off the tutorial by setting up the basics:

Add a Plane: Create a floor for the character to move on.
Place a Cube: Designate a cube as the player character placeholder.
Position the Camera: Ensure the camera provides a clear view of the gameplay area.

Implementing Character Movement

Now, let's dive into scripting the character movement using a "PlayerMovement" script. Here's a breakdown of the key steps involved:

Add Rigid Body: Grant the player physics capabilities by attaching a rigid body component.
Script Setup:
- Define a serialized field for movement speed.
- Access the rigid body component in the script.
Input Handling:
- Capture horizontal and vertical inputs for movement.
- Update the player's velocity based on the input received.
Implementing Jump:
- Integrate jumping functionality using the "Jump" button.
- Prevent continuous jumping by setting velocity constraints.

Orienting the Character

To ensure the character faces the movement direction, a simple adjustment using Unity's built-in functions can be made:

Set Forward Direction: Align the character's orientation with the movement vector.
Freeze Rotation: Prevent unintended rotations by freezing rotation axes in the Rigidbody component.

Camera Follow Feature

Enhance the gameplay experience by implementing a camera follow system that sticks with the player's movements:

Create a Parent Object: Establish an empty object as the parent of the camera.
Script Implementation:
- Define a serialized field for the player's transform.
- Automate the camera's position to follow the player.

By incorporating these elements, you can create a dynamic gaming environment where the camera smoothly tracks the character's movements, offering players a more engaging experience.

Conclusion

In this segment, we've laid the groundwork for a robust character controller in Unity. Stay tuned for the upcoming parts where we will explore advanced features like orbiting camera and movement relative to camera direction.
