Address Type Description
|
|
===================================
|
|
0x013E8CF4 float X-Coordinate
|
|
0x013E8CF8 float Y-Coordinate
|
|
0x013E8CFC float Z-Coordinate
|
|
// The XYZ coordinates repeat at 0x013F79C8, 0x013F79CC, 0x013F79D0
|
|
// and seem to always hold the same values. It is not the camera vs
|
|
// character, as with third person they still hold the same values.
|
|
0x013F9E20 float Horizontal view in degree
|
|
0x013F9E1C float Vertical view in degree
|
|
0x013E8DFC byte Team; 0: not in-game (in menu etc), 1: allies, 2: axis, 3: spectator
|
|
0x009FFD30 char[40] last connected to host IP
|
|
0x010B4908 char[32] map shortname only
|
|
|
|
As reference, as help for future manual mem scanning:
|
|
0x010B48C8 char[32] map fullpath (relative to gamedir)
|
|
0x03A54C9C char[16] last download host IP (wwwdownload)
|
|
There seem to be a ton of memory addresses valid for the team value.
|
|
|
|
For position coordinates:
|
|
X-Value is increasing when heading east
|
|
decreasing when heading west
|
|
Y-Value is increasing when heading north
|
|
decreasing when heading south
|
|
Z-Value is increasing when going up
|
|
decreasing when going down
|
|
1 unit = 1 meter (not confirmed)
|
|
|
|
For the view angle values:
|
|
Vertical view 0 when centered
|
|
-90 when looking up
|
|
+90 when looking down
|
|
Increasing when looking down.
|
|
|
|
Horizontal is 90 when facing north
|
|
0 when facing east
|
|
-90 when facing south
|
|
+/-180 when facing west
|
|
Increasing when turning left.
