Collection of protocol, memory, and other information for the browser game diepio

This is no longer being worked on actively, progress updates will be low.

See diepcustom for recent projects (reimplementation [in a sense] of a Diep.IO backend)

:DiepInDepth

Collection of protocol, memory, and other hacky information for the browser game diep.io.

What started off as an attempt to parse game leaderboards out of packets is now a collection of information about the insides of diep.io. Includes information such as packet encoding/decoding, packet protocol, memory structures, a bit of physics, wasm parsing, game code reversal, and much more.

Sections

There are 7 sections that divide up the information collected.

1. Game Protocol (protocol/)
   Including incoming and outgoing packets, encoding/decoding, m28 server list api, and websocket connections
2. WebAssembly Reversal (wasm/)
   Including any means necessary, asm.js conversion, specific functions, automation of reversing constants and pointers, understanding of emscripten
3. Canvas Reversal (canvas/)
   Including shape sizes, draw sequences, scaling, and color constants
4. Memory Management (memory/)
   Including storage of entities, tanks, the gui, and the structure and way things are stored
5. Extras (extras/)
   Including any extra information, fun facts, misc algorithms, and any physics not provided in Spade Squad
6. Media (media/)
   Including screenshots and other forms of media relating to our research in diep
7. Physics (physics/)
   Including information regarding the properties and nature of entities, such as movement, collisions, and sizes

Before going too in depth into entity-related memory and protocol, it is highly recommended you read entities.md to understand how entities work.

diepindepth's Issues

hi

Hey, hru?

@require cache (solved)

Packet hook gives really bad lag (10fps + ~2000ms)

Discussing XORs in update.md

No information about the xors is present. PRs welcome

Request for PHook API to allow packet modification

I tried editing data in the serverbkund event but it sends the same way as it was supposed to be done.

tanks.js

Line 15 typo, should be "Twin Flank" without the -

Packethook Userscript Error

Uncaught TypeError: this.wasm.exports.recvPacket is not a function
Uncaught TypeError: this.wasm.exports.sendPacket is not a function

tankdefs.js

No info about auto barrels for

• Auto 3
• Auto 5
• Auto Gunner
• Auto Trapper
• Auto Smasher

real vectors have templates

in diepindepth/memory/structs/vector.h, it should have template <typename T, typename allocator = std::allocator<T>>

incoming.md - Building a party link

https://github.com/ABCxFF/diepindepth/blob/main/protocol/incoming.md#building-a-party-link

stringNT("brlm") bytes(0x2D 0xCD 0x03 0x54 0xC3)

62 72 6C 6D 00 2D CD 03 54 C3

Where does 0x2D 0xCD 0x03 0x54 0xC3 come from?

incoming.md - Force strict types on eval packet

On 0x0d packet, im pretty sure when sending back 0x0b packet, format for the result is vu (at least how i encoded the packet).

Question

Is it illegal to make a diep.io server?

Fix 00

• Fix format
• Constant field group reads
• Add update and create data type

I DID IT I FINALLY MADE TEXT INPUTS IN DIEP TYPEABLE
