So, I am following the 1.21 forge tutorials by Kaupenjoe on youtube, and I have run into a problem. In tutorial #8, which is the one about adding foods, he creates a food with effects by using .effect() on the FoodProperties, and he also shows a few other methods, .fast() and .usingConvertsTo(). None of the mentioned methods actually exist when I try to use them. They just aren't there. .saturationModifier, .nutrition(), .alwaysEdible(), and .build() are the only relevant methods that actually exist. What is going on here? Did something change between 1.21 and 1.21.3? I can't find any documentation anywhere.
