new to Unity and c#, need help with triggering audio

Unity Engine
1

Hi all,

Totally new to Unity and c# – having a ton of fun but also some frustration. I’ve learned a lot already through various tutorials and am currently working on a simple project. It’s a game where the player (a rolling sphere) moves over various triggers, and each trigger plays a piece of music (and stops playing the previous piece of music). Kind of like an interactive music playlist where the triggers are the ‘play next song’ button.

I’m having a hell of a time figuring out how to write this script and what I’m supposed to attach it to. I’ve searched through the forums, but a lot of the posts that may have answered this question contain references to old versions of the software or lots of code I don’t yet understand how to read. Any guidance would be hugely appreciated!

Thanks! I’m going through this now, unfortunately running into some obsolete API usages. :frowning: Any help would be appreciated…

The script the tutorial wants me to have created by 11:55 in the video follows at the end of this post. The console gives me several errors when I write it:

  1. Some scripts have compilation errors which may prevent obsolete API usages to get updated. Obsolete API updating will continue automatically after these errors get fixed.

  2. Assets/Scripts/ThrowObject.cs(20,79): error CS0103: The name `newVector3’ does not exist in the current context

  3. Assets/Scripts/ThrowObject.cs(20,61): error CS1502: The best overloaded method match for `UnityEngine.Rigidbody.AddRelativeForce(UnityEngine.Vector3)’ has some invalid arguments

  4. Assets/Scripts/ThrowObject.cs(20,61): error CS1503: Argument #1' cannot convert object’ expression to type `UnityEngine.Vector3’

  5. Some scripts have compilation errors which may prevent obsolete API usages to get updated. Obsolete API updating will continue automatically after these errors get fixed.

usingUnityEngine;
usingSystem.Collections;

publicclassThrowObject : MonoBehaviour {

publicGameObjectprojectile;

privatefloatthrowSpeed = 2000;

//Usethisforinitialization
voidStart () {

}

//Updateiscalledonceperframe
voidUpdate () {
if (Input.GetButtonDown(“Fire1”))
{
GameObjectthrowThis = Instantiate (projectile, transform.position, transform.rotation) asGameObject;
throwThis.GetComponent().AddRelativeForce (newVector3(0,0,throwSpeed));
}
}
}

I didn’t test it, but this is what I would do:

// this follows the naming convention "MusicObject00", "MusicObject01", ...
// for the objects this script is attached to

public GameObject AudioPlayer; // empty that has an audiosource component
public AudioClip[] Songs;

void OnTriggerEnter (Collider other) {
    if (other.gameObject.tag == "Player") { // tag the rolling sphere as Player
        int ThisNumber = -1;
        if (this.gameObject.name.Substring(11,2).Parse >= 10) {
            ThisNumber = this.gameObject.name.Substring(11,2).Parse;
        }
        else {ThisNumber = this.gameObject.name.Substring(12,1).Parse;}
        AudioPlayer.GetComponent<Audiosource>().Stop();
        AudioPlayer.GetComponent<Audiosource>().clip = Songs[ThisNumber];
        AudioPlayer.GetComponent<Audiosource>().Play();
    }
}

Thank you! :smile:
