Loader Preprocessor

The loader preprocessor is really simple, it affects where and when the script is loaded. As of writing this script, there are three loaders registered by CraftTweaker: initialise, tags, and crafttweaker

crafttweaker is the default loader, where most things take place. Scripts here will get executed whenever resources get reloaded, on world join, or when running the /reload command. You don’t need to have #loader crafttweaker at the top of your script.

Loaders are independent. You will not be able to add recipes in a tags loader or create an item in a crafttweaker loader.

How to use

Simply append #loader name to the top of the script.

#loader tags

<tag:item:minecraft:planks>.addId(<resource:minecraft:tnt>);

Other mods may register other loaders under different names. As such, they might load at different points in time and provide certain classes.
