Beep Boop: Emotions for ED-E

Posted on by

So I’m trying to program emotions for ED-E.

Better ed-e dialogue at Fallout New Vegas - mods and community

In Fallout New Vegas, ED-E doesn’t use regular dialogue, but communicates through beeps. Basically, he gets <(Emotion) + beeping> as his dialogue. Obviously the only way to research his beeping for this project is to replay Fallout New Vegas and talk to everyone’s favorite eyebot. I came up with a list of some of the emotional beeps he has in the game (and some that I just want) to start programming into him. I have ideas for what I want him to sound like, but I just need to find the right pitches and durations.

By this I mean I am sitting in my room and saying “beep beep” to myself at different pitches in sync with a program I wrote.

Yesterday my dad was checking in on me and how my programming was going and asked how I was doing. I replied, approximately, “bleurrrrghhhhh.”
I was having trouble programming the emotional beeps because I have very specific ideas for what ED-E should sound like and no way to get that into a computer. I’m a huge music nerd, but I unfortunately don’t have perfect pitch or some superhuman ability like that to use to get ED-E to sound exactly like I want him to.1 Dad suggested using a loop with an array going up every time, which made everything so. Much. Easier.
This plays frequencies starting at 100hz and going up by 10hz every time. I started with 100hz but going up by 50hz every time, but I liked the specificity of 10hz. Once I get in the ballpark of where I want to be, I can then just run the program and correct the pitches if need be.
If you read my last post, specifically the spoiler section, you will know why I started with a shy beep. If you didn’t read my last post, go do that! If you didn’t read the spoiler section, that’s fine. What you really need to know is that I want ED-E to make noises.
I’ll admit, this took a while to get right. Not playing the tones or even figuring out what pitches they were or how long they should play for. No, getting the tones to play was easy. Getting them to stop… was much harder.
ED-E was shyly screaming at me on repeat for at least 10 minutes while I was slowly losing my mind and trying to make him shut up.
I turned to ChatGPT to help me fix this, but it was utterly unhelpful and I ended up fixing the problem myself by deleting a bunch of the garbage it generated. Now the problem was that I had to continually upload the code to make the ShyBeep function run again. I was happy that it wasn’t looping anymore, but I wanted to fine tune the beeps and making it upload again and again was a pain. That’s why I decided to make it run when a button is pressed.2
It took a little while to make it run when a button was pressed, but then it would only run once and never again, even if the button was pressed. I finally realized that this was happening because runOnce was set to false, and fixed that.
Now that I have this framework, it has been much easier to program more beeps. Now I have a sad beep, and I’m going to start working on a happy beep because I have had just about enough of ED-E’s negativity.3

  1. I almost decided to use the definitions of pitch from my Rickroll code so I could just ask the computer to start at middle C and go down or say I want the pitch to be a half note in 3/4 time. I then realized I was making this WAY more complicated than it needed to be and just used seconds and hz like a normal-ish person [↩]
  2. I seriously love Circuit Playgrounds. They have everything. [↩]
  3. Just kidding ED-E, I love you [↩]
