Initially worked on American truck simulator traffic mod that would be based on OS time...
Goofing around with ATS in game timer didn’t lead anywhere there was I expecting to (in fact, for that, needs additional Lua - it is possible to make)
(At Night more traffic - at day time less traffic or versa) ...Ended up with many strings...
This prefix_string to cheat engine symbol can be done with celua code...
..so initially when scan begins (from start address) - it looks for an string with "ExpectedStringPrefix_String" if "ExpectedStringPrefix_" is discovered from first address then script will print in full string form (example "g_traffic") and afterwards jumps 0x140 (to the next string). If code finds "ExpectedStringPrefix_String" it prints another string and at this point (this is loop).
If code fails to find a string from pattern then from temporary location will be jumped +0x8 from temp location (jump variable) forward and attempts again search for "stringprefix*" until given END address is reached.
For each unique case variables/aob's must be accordingly edited!
NearFirstStringAOB, EndStringBlockAOB, block, GetStringList == everything else leave rest of the work to the script...
FirstAddressAOB – Aob pattern there scan starts
EndStringBlockAOB – Aob pattern there scan ends
block – Difference (in hex) between String_1 and String_2..
GetStringList – What strings expect to find
When it could be effective : If you have enabled STRING_TO_SYMBOL=1 : take for example as for ATS : "g_traffic", "g_traffic"+0x110=1 (1 == effective value), increasing value higher than 1 will increase spawned AI's car number...
..and for blocks: g_traffic+0x140=g_kdop_preview+0x140=g_screenshot_on_bug_quality+140=ect...
Note: that scan of aob is based on process (possible to set as module)

and 
. (...) idk. Here am using string prefix as "wild card" and if in the context when games use console or string variable system -- This can be useful. e.g., prefix_string has near effective value.Yet,
In overall could better rewritten from scratch. There is one point -- Here am jumping from start address to end address rather using celua memscan -- which solves block problem ish. (...). Also, here I use a lot of variables as global... instead of local temp = ... (...) ...
Anyway, a bit cleaned code and...
