adding keyboard movement to three.js

response1.md

To add WASD keyboard movement support to the webgl_loader_fbx.html file from the Three.js GitHub repository, you can make the following changes:

1. First, add a controls variable to the JavaScript code near the top of the file, to store the instance of the THREE.OrbitControls object:

var camera, controls;

1. Next, locate the init() function and add the following code after the camera variable is defined, to instantiate the OrbitControls object and set some initial values:

controls = new THREE.OrbitControls(camera, document.body); controls.target.set(0, 0, 0);
controls.update();

1. Finally, add an event listener to the document object that listens for keydown events, and updates the camera position based on the current key pressed (W, A, S, or D):

document.addEventListener('keydown', function(event) {
    switch (event.keyCode) {
        case 87: // W
            camera.position.z -= 0.1;
            break;
        case 65: // A
            camera.position.x -= 0.1;
            break;
        case 83: // S
            camera.position.z += 0.1;
            break;
        case 68: // D
            camera.position.x += 0.1;
            break;
    }
});

These changes should allow you to use the W, A, S, and D keys to move the camera around the scene. You may need to adjust the movement speed or modify the code to fit your specific needs.
