I would just like to tell you that I found a bug. I wanted to put music and custom sounds that I had made myself. So I took my music files and sounds, I put them in .ogg, for the format, and I imported them in my Worskpace on MCreator.
So I started my game because I wanted to see if it worked, and as soon as I wanted to play one of my audio files, I have my game that crashed.
I will tell you again what I did.
1. Put my files I created on Mcreator. (I put .ogg files.)
2. I import all the other files.
3. I start the game
4. I execute the command / playsound testenvironmentmod: thenameofmycustomsoundand / sound.
5. Press the Enter key.
6. I have the game that crash.
I give you the link of my Workspace.
