/*
Arrays of bytes to find addresses accessed by respective functions so we don't have to blindly search for addresses after every update
Remember to disable scanning only the writable memory in CE! We're searching for functions here, not values!
Camera and avatar position function: 89 10 8B 57 04 89 50 04 8B 57 08 89 50 08 DF E0 F6 C4 01
1) Camera position
2) Camera position (?)
3) Avatar position
Camera front vector function: 46 BF 00 89 15 (disassemble, then go up a few times in disassembly)
Unit front vector function: 89 1E 8B 5F 04 89 5E 04 8B 7F 08 89 7E 08 8B 7D 10 8D 71 28
To find the right front vector pointer, you'll need to make a pointer scan for the address that gets updated only when >you< move, using different characters in different locations. It should leave you with only two possible pointers after just 2 scans.
Location function: 8D 14 DB 8D 34 90 8D 4E 14 (target instruction is the one above the one you find)
Area function: A3 58 11 A3 00 E8 B8 02 00 00 BA 37 00 00 00 8B CE
Valid addresses from build b36001
Camera position vector address: 0xa30274
Avatar position vector address: 0xa302a4
Camera front vector address: 0xbf46b8
Avatar front vector address: 0xd55610 -> +0x8 --> +0x0 -> +0x1c
Location: 0xa3fa08
Area: 0xa31158
No need to care about top vector since the game doesn't use it anyway
Context is defined based on location + area combo. This is not enough to be unique in most cases (it doesn't let us distinguish between districts and servers), but it's better than nothing
Location Pointer:
25 or 26: Explorable Area / Mission
26 or 27: Town
0 when logged in / in character select / in loading screen
1 when not logged in (in login screen)
Area Pointer:
This is a 4-byte decimal stating which area we are in. Note however, that some missions have the same area assigned as cities, therefore we need our Location Pointer to distinguish where we are exactly to specify context properly.
