This is a quick test project I made in about 5-10 minutes. The project uses your micro phone to determine how loud you are and makes the indicator equal to that. Being louder makes the icon more visible, larger, and more shaky. I'm thinking about making a game where you have to hide from a monster in a house. It can hear you when you make noise, so you have to stay quiet during gameplay. I want to add little non-harmful jumpscares which might make you jump in your seat and make noise, alerting the actually dangerous monster. Haven't even made the untitled project yet, so it's just a concept so far, but I think it's cool.
Idea and megaphone sprite from Tattletail Code by me (literally 20 blocks XD) Feel free to use code. No credit needed because of how basic the code is. I don't care if you steal it.
