Hello,

 

how is it possible to print something into the launcher when Forge initializes the mod? For example, some coremods (and normal mods) print messages into the log when they're started.

Do you use

System.out.println("<Message>");

or something else?

Also, can someone tell me how you can print messages into the client, so the player can see them in the ingame-chat?

Thanks for help.

Oh and...

Can the mod inside the "src" folder have any folder structure? So, would it be possible to create a mod with 5 main folders and 20 subfolders? 
I don't know if that could ever be the case, just an example.

Use log4j, the logging library used by Minecraft.

 

To get a log4j Logger instance, you can either use the methods from LogManager or use FMLPreInitializationEvent#getModLog, which returns a Logger with your mod ID as its name.

Call ICommandSender#sendMessage on an EntityPlayer (or any other ICommandSender) to send them a message.

 

The most commonly used ITextComponent implementations are TextComponentTranslation (a translation key and format arguments translated and formatted on the client) and TextComponentString (a simple string).

You can use any folder structure you want inside src/main/java as long as your packages match it.
