Hello, may I say firstly, this application is simply the best!!!

I’m testing 3ds MAX version and I’m interested if it is possible to programmatically set/change parameters (as this is not possible with puzzles?) for current camera and call that function with JS function puzzle in specific moment?

I would like to change parameters like “Min Distance”, “Max Distance”, “Min Vertical Angle”, “Max Vertical Angle”,… on some event.

Hello,

yes, this is possible with JavaScript

Thank You very much for directions!

I’m trying, but simply can not figure out how to control camera parameters. I’m novice in coding.

I know how to work with existing camera as an object:
var object = app.scene.getObjectByName(‘Box001’);
var camera = app.scene.getObjectByName(‘Camera001’);

object.rotateZ(0.1);
camera.position.set(0, 20, 100);
etc… that works!

But how to change OrbitControls?
var controls = new v3d.OrbitControls(camera); —> turns window in to black Do I have to “select” an exiting OrbitControls here?

controls.maxAzimuthAngle = 2;
controls.minAzimuthAngle.set = 3;
controls.update();

That OrbitControls object is automatically created and can be accessed through the App instance:

app.controls

Sorry for hogging the thread, but how would i access the app from the browser developer console. I thought I could get at it from just typing “app” but i guess the OOP-ish stuff in JavaScript is confusing me a bit here os something …. I find it really useful to quickly test things out there compared to running the whole app over and over while testing things.

If You use Chrome, Vivaldi, Opera by pressing F12 or Control+Shift+J on keyboard if I understand you correctly?

Yeah. I get that far, but if i type app.controls or even just app in the console there it gives me a “not defined” error. I use it to debug javascript on my own scripts, i am just having a hard time getting access to the app, but i think it might be a scope issue, and I really need to brush up on my “OOP” skills regarding JavaScript. But thanks for the sugestion :)

Yep, the app variable is not globally exposed. But you can add

window.app = app;

to the runCode function and it’ll get exposed.

Ahh. Will check that out. Should probably have been able to figure that out myself, but thank you so much Yuri

EDIT: Worked like a charm, thanks :D
