Hi,

My first post here and new user of CE. I've spent some hours with moderate success on CE over the past few days, but seem to have found a few hiccups on my path.

Let me explain what my goal is and how I planned to use CE in accomplishing that goal, what I've done since starting with CE and the limitations I am now assuming.

I have written a bot for a flash based game using image scanning which was more to learn about that technology than anything else. The bot has since evolved quite nicely but is having real performance and reliability issues now requiring constant babysitting. Fetching trivial information like hp and food levels is a massive chore.

I want to use CE (or similar mechanic, ie. memory address reading) to fetch information from memory so I can reduce image scanning and improve reliability.

So what seems to be a known limitation due to flash/java is that I can not find any green pointers for the values that I need, even in read-only mode, which is obviously not sustainable for me, as I require my bot to query CE or similar engine for specific data readable from memory, without having to figure out each time what memory address its at. I would have thought finding the starting address for the flash dll + additional address from pointer scanning might work, but that does not.

Given that I am new in this arena, is what I mention above worth pursuing and reasonably possible. I've looked threads relating to flash games, and have found little light at the end of that tunnel.

Any feedback or advice on the above would be greatly appreciated.

Search for "injection copy" or "injection copies" for tutorials on an alternative method to get the address of the value you want.

Thanks for the response. I did make some progress on this and found a working solution with AoB scanning as well as started familiarizing myself with the LUA Engine.

Given that my bot runs in it's own application, I am looking for a way for CE to make available the values it finds.

Something like this.

Start Game - get pid and attach to CE
Load and Activate cheat table and AoB Scan scripts
-- At this point I have the addresses and values needed by my bot
However, as my bot runs, these values are changing, and my bot needs to know what the values are at any given time

Using the LUA engine to write these values to a file every second is not viable.

It would be great to just have something that updates a file or database on change for each address, but I'm not sure if that is out of the scope of what CE offers.

Some questions I'm looking into which could lead to the desired result:
Would that be a plugin I'd need to write?
Make use of a 3rd byte scanner library?
Can I call CE from my bot to execute a LUA script to update a database?
Can I use an external LUA script with CE libraries to get address values from my AoB scan and related addresses.

This might be easier:
https://docs.microsoft.com/en-us/windows/win32/memory/creating-named-shared-memory

CE's implementation is in Cheat Engine/sharedMemory.pas. The Lua API can access "allocateSharedMemory(name: string; size: integer): THandle" (pascal function) as "allocateSharedMemoryLocal(name, size)" (Lua function).

DB recently posted an example of what this looks like between two CE processes here.

Have CE give the address of the values to watch and call ReadProcessMemory yourself. e.g.:
