[1.12.2] Check if environment is deobfuscated

[Arandomdud]

Is there any way to check if the environment is obfuscated or not?

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.

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

	Loader.instance().activeModContainer());
	

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