runelite VS leaks

It would actually probably infinitely less sophisticated than the modern open source oldschool runescape clients.

I've been wanting to write an ebuild for https://github.com/open-osrs/runelite

It's a well known fact that if you don't move the mouse or the server doesn't get any mouse input for X game cycles, it logs you out. You can even see the same logic in OSRS: https://github.com/open-osrs/runelite/blob/804a3e85b81b1fb101dfff14e9e9302cb4331bfe/runescape-client/src/main/java/Client.java#L3856

Essentially, the packer that creates the game cache does so by iterating over each of the NPC configs (example), packing the parameters in the order they're defined. If the combat level is set manually in the config (either because it's 0, or because it's overridden like Hazeel/Combat Instructor), then it will be packed somewhere near the beginning of the NPC definition.

https://github.com/RuneStar/leaks has a lot of other interesting stuff about runescript/rs in general

No RSPS server uses leaked code from RuneScape. All of the server implementations have come from reverse engineering the client.

Also, all of RS content is written in RuneScript, Jagex's custom scripting lang, so you wouldn't be able to easily use a leak (nor would you want to.. it's hideous: https://github.com/RuneStar/leaks/blob/master/101.0.jpg)
