Creating first-person shooter game controls using Three.js in JavaScript

I am currently in the process of creating a small 3D FPS Game using Three.js, but I am in need of assistance with the controls.

To better illustrate what I am aiming for, please watch this video to see the desired controls in action (only the controls, not the entire game world): https://www.youtube.com/watch?v=WDDJDTeTBc4

Despite my efforts, I have been unable to locate any open source examples or tutorials on how to implement these controls. Therefore, I am reaching out here for help. Could someone please provide guidance on what steps I need to take?

I have considered the following approach, but I am unsure if it is the most efficient (fast) method: - Locking the mouse pointer (how can I adjust the camera 'rotation'?), allowing mouse movement to control viewing direction - Implementing key controls (W, A, S, D for movement) - Placing a character (simple sphere geometry) behind the camera

Is this the correct approach? Similar to controls used in Minecraft, with a character positioned directly behind the camera. Any suggestions? I greatly appreciate any comments that can assist me in this endeavor.

Answer №1

If you're looking to move your character around with the camera, you can easily achieve this by either adding the object to the camera or adding the camera to your object...

For example:

var character = ...

var camera.add(character);

var controls = new THREE.PointerLockControls(camera);

While this code snippet has not been tested, it illustrates the concept.

For more information, you can reference the source code of the provided example.
