Playing multiple sounds on same key input ("e")

Question

Hi people,

So, I haven't been on Unity Answers in a while as I like to learn things the hard way.. However, this one has just completely frustrated me and I just can't seem to wrap my head around it.

The way I want this to work is by the character going up to a cup to press the E key which should then play the first sound, WAIT FOR IT TO FINISH, then when they press the E key again, it should play the soundClip2 AudioClip and then WAIT FOR IT TO FINISH, and lastly, play the soundClip3 when the user presses E.

After that is all done, I want it to go back to the top of the script. Do I need to add a Function Update or anything?

It would be really appreciated if you could get me sorted on this problem as it's begun to put a halt on my project.

public var soundClip1 : AudioClip; public var soundClip2 : AudioClip; public var soundClip3 : AudioClip; // Play default sound function OnTriggerStay (col:Collider){ if(Input.GetKey("e")) { audio.clip = soundClip1; audio.Play(); yield WaitForSeconds (soundClip1.audio.clip.length); } else if(Input.GetKey("e")) { audio.clip = soundClip2; audio.Play(); yield WaitForSeconds (soundClip2.audio.clip.length); } else if(Input.GetKey("e")) { audio.clip = soundClip3; audio.Play(); yield WaitForSeconds (soundClip3.audio.clip.length); } }

Here is the scene I am working on

Because I can't get this script to work, I have decided to stick to a shortenered version of it, but that's not what I want as it only plays one sound. ALSO when I keep pressing E, it spams the sound.. I want it to play the sound once, and then when it finishes, it plays again when the E key is pressed. I have tried PlayOneShot, and it tells me something like Unity can't support it or so..

 public var soundClip1 : AudioClip;
 public var soundClip2 : AudioClip;
 public var soundClip3 : AudioClip;
     // Play default sound
        
    function OnTriggerStay (col:Collider){
     
 
         if(Input.GetKey("e")) {
              audio.clip = soundClip1;
              audio.Play();
              yield WaitForSeconds (soundClip1.audio.clip.length);     
            
      }
     }

**If you manage to understand the problem I am facing, I won't know how much to thank you! Please please please! Help me out! The Unity Community is very good and that is why I have chosen to write my issues here.

Thanks.**

Hello,

Assuming the OnTriggerStay() is actually triggered, I think you can simply do like this:

 public var soundClip : AudioClip[]; //to be assigned in inspector
 private var looper : int = 0;
 
     function OnTriggerStay (col:Collider){
      
          if(Input.GetKey("e")) {
              if(!audio.isPlaying)
              {
                      audio.clip = soundClip[looper];
                      audio.Play();
                      looper++;
                      looper = looper%soundClip.Length;
             }    
      
          }
      }

regards
