PlayerWithoutName

How can i do it? I'm programming in C++ , not java

But how? When i execute it like that: it throws me: Exception in thread "main" java.langSecurityException: class "sq"'s signer information does not match signer information on other classes in the same package. ;( I think it's something about META-INF folder.

Hello, I'm making a launcher for my modpack and i want to launch Minecraft with Forge without repacking minecraft.jar, do You know how MultiMC loads mods from instMods or TechnicLauncher loads modpack.jar? Thanks for help.
