Need UI Canvas to appear AFTER audio finishes on trigger

Questions & Answers
1

Hi there,

I have a Sound Trigger set up so that when the player enters the audio will play once. What I cant figure out is how to make a canvas I have with buttons appear AFTER the audio finishes. The canvas has buttons that when selected will trigger more audio and I do not want the user to press the button until the triggered audio completes. Below is the code I have so far:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class AudioTrigger : MonoBehaviour
{
public AudioClip audclip;
public bool havePlayed = false;
void Start()

{
    havePlayed = false;
    GetComponent<AudioSource>().playOnAwake = false;
    GetComponent<AudioSource>().clip = audclip;
}

void OnTriggerEnter(Collider whoCollidedWithMe)       //Plays Sound whenever collision detected
{
    if (!havePlayed)    // !havePlayed is the same as havePlayed==false
    {
        // we haven't played yet, but someone collided with us. Who is it ?
        if (whoCollidedWithMe.gameObject.tag == "Player")
        {
            GetComponent<AudioSource>().PlayOneShot(audclip);
            Debug.LogWarning("are u working");
            havePlayed = true;  // we played, so never again
        }
        else
        {
            // not the player, so do nothing
        }

    }
   
}

}

What you could do is Invoke a method with the length of the audio clip, so something like this:

            Invoke("EnableCanvas", audclip.length);

The invoke will call a method named EnableCanvas (that deals with enabling it) with a delay for as long as the clip. Just put this under your playOneShot(audclip);

It could also be a coroutine - StartCoroutine(EnableCanvas(audclip.length);

Then have the yield the length of the clip. yield return newWaitForSeconds(length);

Hi @Vega4Life! Thanks for your help.

I am really new to coding, could you provide more detail for the Coroutine route? Not sure where to put that in the script :confused:

Thanks
