Hello all,

Question in short:
Why mouse wheel zooming gets corrupted after changing controls?

Longer Description:
I have a simple scene (which I attached to this post) with orbit controls at the beginning and mouse wheel scroll works fine for zooming.
I also have a red button on top left that on click, toggles the camera controls between FirstPerson and Orbit. When I click it once and switch to FirstPerson, the mouse wheel does not zoom correctly (but the w button works fine for zooming) and it jitters and jumps as you can see in the attached video. After that even if I click on the red button to change the controls back to Orbit, mouse wheel does not work correctly.

see below…

Puzzles and JS coding. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

```
function runCode(app) {
    // add your code here, e.g. console.log('Hello, World!');

    var isFP = false;
    var prevControls = app.controls; //save OrbitControls with all parameters

    $("#change_control").click( function() {
        console.log("controls changed");

        if (isFP) {
            app.controls = prevControls;
            app.controls.enabled = true; //enable OrbitControls
        }
        else {
            app.controls.enabled = false; //disable OrbitControls
            app.controls = new v3d.FirstPersonControls(app.camera, app.renderer.domElement);
            //app.controls.zoomSpeed = 0; //disable wheel zoom
        }
        isFP = !isFP;
    })
}
```

that’s because Orbit and FirstPerson controls were both active )))
