Topic: Unity and Javascript

[Elod-Hora]

Hey peeps,

I've started using Unity again, yesterday... Hope it'll lead me somewhere

In the meantime, a small question:

How do I change constant force parameters of an object by user input?

For instance, I've got an object selected, how do I change its rotation speed?

Cool! Unity is pretty easy to pick up!

Here's some links:

Tutorial

Unity Script Reference

Here's your line of code, pressing a will result in rotation:

if (Input.GetKeyDown("a")) {transform.Rotate (Vector3.up, -120);}

If you want to add time, I'm not sure, probably add the delta time function somewhere, but I'm not really good at JS (or any code).

Changing it's rotation speed manually, sounds like you're already running a code and you just need to change some parameters, which you can do without closing it, unless you've hard-coded it into your script.

Thanks for the string, I'll try it at home

Well, basically I've put Unity's ConstantForce to get a textured ball rotating. You can easily modify the speed and the direction of rotation in Unity itself, but you have no control over it ingame.

And yep, I've completely forgot EVERYTHING I've studied about JavaScript, so it's a pain.

I haven't really had a lot of practice with JS and I have never used unity (I do plan on doing some projects with JS and HTML5 just for experience probably during the summer when I have time )

But usually graphical applications follow this model
1. set everything up
2. present to the user
3. wait for an event
4. handle event and go back to 2

also you usually have background computations so the scene is alive even when user not clicking anything

I know JavaScript can monitor events such as mouseclicks
hope this helps if you want to take up something like directX I will be more useful to you

Instead of having a fixed camera, for the first build I actually opted for another solution. Will work on the that one later on.

Click me for testing!

cool !
looks like its easier to move the camera in some directions than others though
