Hello, i have looked to find the Vanilla Code, but i simply cant find it. I followed a tutorial on youtube for the 1.15.2 and i have this code:  https://github.com/DragonGamerDevelopers/NewFantasyMod/blob/1.15.2/src/main/java/mod/dragonita/fantasymod/world/gen/FantasyOreGen.java#L25 Then i looked into my World to see if it worked or not, but nothing, i cant find my Ore. I ask here: does my Code actually work and if not, then why?
