Making a custom Client

[thenyanman]

I dont know if anyone will help me out here since i have a vague memory about people saying no one would talk about it, but i have seen that a server has introduced a custom client with mods from both forge and liteloader, and i see old tutorials about how to include mcp with forge but they no longer work. Im an imaginer and right now my brain cant understand the concept of what to do. Ive been stumped for months now on this and i was just wondering how to get the src files into MCP (my interpretation of what they have done to create the client is to include the src of forge inside of the client but I am truly stumped. If anyone could help me i would be eternally grateful)

 

i tried using this but i dont quite fully understand https://github.com/MinecraftForge/FML

I understand the information i have provided is a bit vague so here's the link to the client the other server made: https://cosmicclient.com/

I did some investigating, and what they're doing is not allowed:

• They're asking users to input their credentials into their 3rd party launcher. Mojang doesn't want this because of security.
• They're rehosting the Minecraft libraries and game on their own server. That's illegal.
• They combined all the mods into a a single JAR with the actual game, and put it up on their server. That's also illegal.

They even re-obfuscated the Minecraft source code...

 

If you were using that launcher, you should stop doing so.
 

They're not using Forge, so I don't think the Forge team can do anything about it, but Mojang should really be after these types of launchers.

 

What you can do is something similar to what the Twitch launcher does. The launcher downloads the mods (don't package them in the launcher!!!), and open the vanilla launcher with the path to the profile folder.

 

Then again: is it really worth it? I imagine it's way easier to upload a modpack to Curse and have the users install that...

You should inform Mojang.
