-  - If it is a static method (accessed from a ReflectClasses' `staticMethods` property), call the method as usual. Eg: `ModAPI.reflect.getClassById("net.minecraft.init.Items").staticMethods.getRegisteredItem.method(ModAPI.util.str("apple"))`

+Keep in mind that you need to wrap strings using `ModAPI.util.str("MyString")`, convert booleans into respective numbers (`true`->`1`, `false`->`0`), and get references of ModAPI proxies (`ModAPI.player`->`ModAPI.player.getRef()`);
