[1.12.2] Check if environment is deobfuscated


Recommended Posts

I assume you mean whether the MCP names are applied or not, since your mod will never run in a vanilla minecraft environment(unless you are doing jar mods/coremods but we don't talk about that)

You can simply use reflection to check for an existance of any field in vanilla minecraft's code with it's mcp name. If it exists then your environment is the dev environment. If there is no such field then it isn't.

Forge already supplies a is deobf field somewhere, but I can't remember where it is. You don't need to use reflection.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.


Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.


DO NOT PM ME WITH PROBLEMS. No help will be given.

You can check if the environment is a developer environment with

	final boolean developerEnvironment = (boolean) Launch.blackboard.get("fml.deobfuscatedEnvironment");


You can check if runtime deobf is enabled (means that it is not a developer environment) (going away in 1.13) with

	final boolean runtimeDeobfuscationEnabled = (boolean) data.get("runtimeDeobfuscationEnabled");


You can check if your mod is the mod being developed in a developer environment with

	final File modSource = Something.getActiveModContainer().getSource();
	final boolean amIBeingDeveloped = modSource != null && (modSource.isFile() && modSource.getName().endsWith(".jar"));



Edit: “Something.getActiveModContainer” is actually


but cause I’m on mobile I can’t edit it.
