Creating a 3D Scene in Godot 4: A Step-by-Step Guide

Are you ready to dive into the world of 3D game development using Godot 4? Building a 3D scene in Godot 4 can seem like a daunting task at first, but with the right guidance, you can create a captivating environment where your characters can come to life. In this blog post, we will walk you through the process of creating a 3D scene in Godot 4, complete with a playable character, camera controls, and basic movement functionalities.

Setting Up the World

To kickstart your 3D scene in Godot 4, the first step is to create a world that your characters can navigate. Begin by adding a 3D node and setting up a mesh to serve as the floor. By adding a mesh instance with a plane mesh as your floor, you can create a spacious area for your characters to explore. Don't forget to adjust the size of the plane to ensure ample space for movement.

Adding the Player Character

Next, introduce your player character into the scene by creating a character body node. You can then attach a mesh instance, such as a capsule, to represent your character's body. Fine-tune the positioning of the character to prevent clipping through the floor and add a collision shape to enable interaction with the environment.

Implementing the Camera System

For players to view and navigate the scene effectively, incorporate a camera that can rotate and follow the character's movements. By adding a pivot node (neck) for the camera to rotate around, you can achieve realistic camera controls. Ensure the camera is positioned correctly within the scene and set up mouse capture to enable smooth camera rotation based on player input.

Implementing Character Movement

To allow your player character to move within the scene, set up basic movement controls using scripts. Utilize template scripts provided in Godot 4 to streamline the process of implementing character movement functionalities. Customize key inputs to facilitate character movement using keys like 'W,' 'A,' 'S,' and 'D' for forward, left, back, and right movements, respectively.

Enhancing Camera Controls

To enhance the camera controls and provide a seamless viewing experience, incorporate mouse input for rotating the camera horizontally and vertically. By tracking mouse motion events and adjusting the neck and camera rotations accordingly, you can simulate realistic camera movements within the 3D environment.

Optimizing Character Direction

To ensure that the character moves in the direction the camera is facing, update the script to calculate the forward direction based on the rotation of the neck node instead of the root character. This adjustment ensures that the character moves relative to the camera's orientation, enhancing the player's experience.

Conclusion

In conclusion, creating a 3D scene in Godot 4 involves meticulous planning and execution of various elements, including world setup, character creation, camera implementation, and movement controls. By following the step-by-step guide outlined in this post, you can craft immersive 3D environments with interactive gameplay mechanics. Embark on your game development journey in Godot 4 and unleash your creativity in building captivating worlds for players to explore.
