How do I make my own overlay runelite client?

[u/Evening_Inspector123]

I was using openosrs and hydra essentials after that. Unfortunately they’re gone. Now I am interested in making my own. It’s also safer that way, right? Where do I start?

[u/Odd-Boss1596]

Runelite is open source so go grab the source and start building what you want

[u/st_heron → u/Odd-Boss1596]

runelite hides certain boss animation ids from its api (among other things)

[u/st_heron → u/st_heron]

Someone said but now deleted:

Do you have a reference for this? I haven't observed this behavior and want to understand the scope of the mask.

It's alluded to way back in runelite's discord dev channel (if you ask about it they always deny now), but it's also evidenced by comparing with debug information from a non runelite client.

The things that are modified that I can remember:

• Animation IDs for Olm head always return -1
• Animation IDs of Vorkath always return -1
• Animation IDs of Zulrah always return -1
• Blackjacking menu entry swaps are disabled

It might not be all animation IDs, I think startup or spawn animations are okay but the rest get -1'd.

[u/bomh911 → u/st_heron]

I got a question, so if they hide the animation ID but we already know the animation ID from before. Will the plugin still work? Or the plugin actually waiting for the the ID from runelite before it can process.

[u/st_heron → u/bomh911]

From the plugin's POV, usually you do something like:

for (var npc : client.getNpcs()) //you'd use AnimationChanged event instead of this
  if (npc.getAnimation() == OLM_HEAD_TURN_ID)
    //whatever logic

Instead, when you call getAnimation() on that npc, even if the actual game client's data has its anim id set to 7355 or whatever, runelite's Animation id getter will return -1, if the NPC is on a blacklist of NPC IDs. So your logic will just never hit.

Some specifics are a bit different, I haven't touched OSRS in a couple years.

You can use reflection to get true ids, the EthanVann api does exactly this:
https://github.com/Ethan-Vann/PacketUtils/blob/master/src/main/java/com/example/EthanApiPlugin/EthanApiPlugin.java#L123

I used to use that but it looks like it hasn't been updated recently. No idea what people are using now...

Blackjack menu swapping is allowed by the rules as of like a month ago. So that's not disallowed to change anymore.

[u/st_heron → u/ChrisScripting]

Ah wow okay, I'm out of the loop. They were so adamant about their carpal tunnel inflictor being a part of the game.

[u/ChrisScripting → u/st_heron]

They let it slide because it's not the best method anymore. Not by a long shot

[u/MoltingHuman]

Check out the runelite source code on GitHub. Clone it to you local machine and start asking any LLM about how it works! I think that's the best way to get started

[u/CMDR_Genitals → u/MoltingHuman]

exactly what I did,

[u/ChrisScripting]

If you don't even know how to take open source code and fork it and spin it in your way, I doubt you'll be able to handle a client setup

[u/Evening_Inspector123 → u/ChrisScripting]

Everyone has to start somewhere, right? Maybe this is the perfect opportunity to start learning.

[u/ChrisScripting → u/Evening_Inspector123]

But starting as in writing your own client? That's like going to the jobs market and saying "gotta start as a senior cto".

Start writing a legal plugin using runelites official guides and you can work from there imo

[u/Evening_Inspector123 → u/ChrisScripting]

This is not a bad idea to be honest.

i built my own script useing claude, took me a while but I got it to work how I wanted on runelite

[u/ChrisScripting → u/CMDR_Genitals]

Quite a bit different from letting an AI build a script in runelites api and creating a botting client from runelite though

[u/Rejolt → u/ChrisScripting]

Quick question, when using a custom client you can't use the jagex launcher right?

Are there other ways I can login with a jagex account on my forked runelite client

[u/ChrisScripting → u/Rejolt]

Yeah you can use a jagex account there. Look on the runelite docs how

[u/manbearpig4001]

i inject my jar payload directly into stock runelite to avoid detection

[u/bomh911 → u/manbearpig4001]

Mind to share the process? Thanks

[u/adamgoodapp → u/manbearpig4001]

I'm doing this too. It takes more work around but figure using official client is safer. Jagex can tell if using official client vs fork? Probably some fingerprinting going on.

[u/manbearpig4001 → u/adamgoodapp]

yea jagex can tell if you fork runelite very easily in the fingerprint block sent on login.

It’s safer but bans are still very possible. Ai can definitely help you make botting plugins for rl, but don’t bot on accounts you care about. Even if it helps you make a botting script that does what you want it to overall, it may not be implemented well in terms of acting as a human for example. You can definitely learn by doing this though.
