Ok, to read x,y,z for your player, first you need your player base.
This can be found at
Code:
Playerbase = [[[0x127E014] + 0x30] + 40]
Then from there you read your x,y,z,rotation values:
Code:
0x7D0 X coord
0x7D4 Y coord
0x7D8 Z coord
0x7DC rotation
For example: my characters current x value:
Code:
x= [playerbase+0x7D0]
Where [] is memory read.
If you are using C# it would look something like
Code:
playerBase = BlackMagic.ReadUInt(BlackMagic.ReadUInt(BlackMagic.ReadUInt(0x127e014) + 0x30) + 40);
playerX = BlackMagic.ReadFloat(playerBase + 0x7D0);
Hope that helped.
