I couldn't find anything useful, but I did an "ALL" search and managed to identify a float reinforcement point value that sticks. I set it 9999 and could basically mobilize full army against AI, only on SP Skirmish mode.
Curiously, watching replays of matches in which I cheated showed funny results: A summary is just the match being replayed by 2 AIs, which don't have cheat engine running so the replay in no way reflects what happened.
Test this and see if it works on your planes and all other units. I'm extremely amateur when it comes to building scripts, but simply replacing the code to subtract a plane/unit when left clicking works for me. It works on game restart for me, but I'm not entirely sure if each game has the same structure. I'm sure someone more skilled could make this reproduceable 100% of the time if it doesn't just work right out of the box.
Need someone to test this on the June 16 Lannes Update and tell me if it actually works or not. If it doesn't, I'll try to fuck around with AOB scans and shit.
It likely won't, since I can't seem to figure out how to implement the correct AOB syntax, but you can EASILY do it yourself.
1.) On match start search for the amount of units in a card you have left (say 6), using the 4byte search.
2.) Buy one, place it, and search for the new number (5). Buy another, and search for (4), etc. Keep doing this until you've found the last few values.
3.) Change those last few values by 1 digit (from 6 to 7) one at a time until you've found the correct one.
4.) Now, right click the correct address (the one controlling units left in card), and "Find out what accesses this address".
5.) Buy and refund it a couple more times until you find the address that has the words "sub [rbx+38,r12d" in it.
6.) Click that value and then press "Show Disassembler" on the right side of this window.
7.) Copy the address (ex: WARNO.exe+A4106C), open my script, and paste it over the addresses in my script. Now toggle the script, and it should work.
