All materials except pneumatic cylinder, FIRST YOU NEED UNLOCK THE MATERIAL OTHERWISE IT WILL NOT WORK... So as I said before this game is pain in the a.ss, it seems that the addresses and values changes every 5 or 10 min and if you minimize the game for a second...Sometimes the old adresses remain as residues in your memory and it causes some materials not to work, but it is enough to restart the game... If you need to freeze a specific material you can find it 40+3 dword, range JH, or just make a fuzzy search if you're lazy, same goes with life, energy and perks.... Perks are weird... after a specific number they seems to reset and if you modify it, it will delete all of your perks lol so I'll see if I can find something more reliable S.A.D(cave rpg script).lua
