I'm having trouble finding the addresses... Thanks to @epicbottt he was able to get me started by basically telling me to use IDA Pro to find the addresses. I downloaded and spent the last couple of hours figuring out how to use it. I've finally figured it out. I made a dump of BF1.exe, and loaded it, then generated strings (shift+F12). Then I did a simple search for the addresses I'm trying to find, for example I used PhysicsManager
Then I double click it, and it points me to it in HEX View
Then I convert it to CODE by pressing the C key...
and here's where I'm stuck. I have no idea what the actual base address is, there are so many
