How does the installer works ?

[natinusala]

Hello,

 

I would like to know what was the installer doing exactly to the client ? Is there any way to have a bundled JAR file with both Minecraft and Forge, which can be used as-it, like any of the normal game JARs (like the old mods, having everything bundled into minecraft.jar except the /mods folder) ?

 

I am doing a custom launcher creator and I would like to include Forge into it ^^

 

Thank you !

Forge can't be installed to the mods folder like other mods because Forge is what causes mods to be loaded from the mods folder.

Forge is a jar mod.

I know x) You misunderstood my question ; I was wondering how to install Forge in the JAR of the game manually, instead of using the installer ?

 

I tried copying the files of the universal Forge JAR into the game JAR but nothing changed...

Launcher works on "profiles" and "versions".

To launch Forge, we need to hack the "version" file. This is done by copying the "version" file and hacking the copy.

We then copy the forge jar in as a library, as well as what forge needs.

Lastly, another "profile" is made which allows you to just start modded minecraft using it.

Okay, thanks

 

Just a few other questions ^^' Should I merge the original JSON and the Forge one or just replace it ? What is serverreq/clientreq ? processArguments ?

Should be self explanatory, if not you'll have to look in the internals of launchers as we can't help you here.

There is no 'hacking' going on, We just run Forge, using Minecraft as a Library.
