I am trying to make a Minecraft map thing (sort of like Skyblock but not really) and it is an entirely Warm Ocean Biome world. I want to make the text in the corner when you unlock a crafting recipe say "New Blueprint(s) Synthesized" instead of "New Recipe(s) Unlocked" as a Subnautica reference. I plan on using a custom resource pack and I am somewhat experienced in commands, but I don't want to use a datapack or mod unless necessary. I think custom leave/join messages in chat are customizable using a custom language or something? I saw a different message that the usual one in a YouTube video once but it might have been one of the built-in Easter Egg languages, idk. I googled "How to change minecraft text," "How to change minecraft new recipe unlocked text," and similar variations but everything was about JSON formatting. Any help is appreciated c:
This is what I mean by "New Recipe Unlocked" text btw
Edit: For clarity, I don't want to play the text-to-speech that the PDA says in Subnautica, I just want to change the on-screen text c:
