Questions[unity3d]

Hello, I am making a game of ships and I place a meteorite but when I execute it it goes to the side or up and I need the meteorite to go down towards my main character, this is my code.

{
    public float Velocidad = 6;
    Rigidbody rb;

   
    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody> ();
        rb.velocity = Vector3.back * Velocidad + Vector3.right * Random.Range(-1, 1);
        rb.angularVelocity = new Vector3 (Random.Range(-5, 5), Random.Range(-5, 5), Random.Range(-5, 5));
    }

I'm making a game in Unity 3d, platform type, with scroll to the right. Now I am with the sound part of the game, and I don't know if there is something similar to the term that I put in the question. I try to explain it (I'm sure it has a name, but I don't know it, I've called it spriteSheet de sonido).

In the case of sprites, we can use a single image that we split with the Unity3d image editor, to be able to use each "piece" of image, as a sequence, or a part of animation, platform, etc.

The question is if there is something similar to the spriteSheet, but for audio.

I have an audio that I can play at any time with:

public AudioClip miSonido;
void Start () {
    source = GetComponent<AudioSource>();
}

void Update () {

    if (Input.GetButtonDown("Fire1"))
    {
        source.Play(miSonido);
    }
}

}

What I would be interested in is being able to access a part of that sound, and play it in a loop. In such a way that later, at another point (for example, when colliding with a tree that I have in one part of the stage) another part of the sound begins to be reproduced. But this being the same source file.

come on, what if there is something like this:

source.Play(miSonido, startAt, endAt, bucle)

(I made this last up, it's more or less to indicate what I'm looking for)

I shouldn't have a problem figuring out the possible time startAt. endAt I can use Audacity or another sound editor to locate the moment of time.

I have the following situation, I am using two identical images, which have a different color to read it in Vuforia 's AR . When creating the database, I defined each one with a pattern, in this case it would be one in purple and the second in pink. Add two ImageTargets in which I defined a Spirte in each according to the color of the image.

What is happening to me is that whenever I read one or the other, the same Sprite always loads me even though they are different. What I want is that when I read purple, the one that responds to that color will load me and so on with the other.

Note: I am not using any script to do this action.

I have a scene with 1 moving object and a canvas with a button playand when I run the scene the object moves because it has a certain Script assigned with a speed and so on... But the button playis in the center.

What I want is for everything to be still and when I hit the button, the button it will be with disappears button.setActive(false)and the object moves.

I'm trying to access them scriptsto do it but it won't let me refer to them and I don't want to start putting them staticor not staticbecause it would throw everything off, how can I do it so that once I hit the play button on the canvas, the other is executed? Within the same scene everything.

A possible solution would be to cancel 1 scriptand until you give "play" not execute that script (the movement of the object), but how do you do that?

Script to move the object:

public class MoveBall_ : MonoBehaviour {


public float velocidad = 10f;


private void Update()
{
    transform.Translate(new Vector3(1f, 0f, 0f) * velocidad * Time.deltaTime);
}
}

What I need is for that to velocidadbe 0 before clicking on the button playon the canvas, and when clicking on the playsecondary canvas that I have placed (which I think I know how to do) disappears and the ball starts to move just like that Script .

I have tried to configure the export of a simple project to webgl in unity3d but I am not sure how much memory I should allocate in the PlayerSettings.

If I put 16 I get

If I put 60 I get

Experimentally I found that on localhost it works perfectly with 40

But I understand that it depends largely on the equipment that runs it (Mine has 16 gigs of RAM and a 1 Giga nVidia graphics processor )

Is there a way or formula to calculate the appropriate amount to work on the most computers? Do I need to change my settings when exporting to a hosting server ? Is there a way to dynamically allocate that memory and work on all computers?
