The modLoaded Preprocessor only executes a script, if a certain mod is present.
You call the modLoaded Preprocessor by adding
#modloaded modID to your script file, with
modID being the modId you want to check for:
You can also provide multiple modID’s:
#modloaded minecraft tconstruct will only be executed if minecraft AND tconstruct are loaded.
What it does
If you added this preprocessor to a script, it will only be executed if the provided modID’s are present, in other words if the respecting mods are loaded.
