    Using vtablescanner from: https://forums.alliedmods.net/showthread.php?t=146379

    This works on linux only.

    Download from: https://delftelectronics.nl/empires/tools/vtablescanner3.zip

    Instructions
    • Unzip [optionally rebuild]
    • Download empires dedicated server.
    • Copy libsteam_api.so, libtier0.so, libvstdlib.so and server.so to the Release folder
    • Open a shell in the Release folder
    • run:
      Code:
      LD_LIBRARY_PATH="./" ./vtabledump ./server.so '_ZTV10CEmpPlayer'
    • First column is the function name, second column is the windows offset, third column is the linux offset.

    Attached version 4

    This replaces game.empires.head.txt with the newer signatures from 2017+ version from Sourcemod gamedata file. (should only affect sdktools I believe)

    Following part:
    Code:
    "Games"
    {
       /* General Temp Entities */
       "#default"
       {
         "Offsets"
         {
           /* Offset into CBaseTempEntity constructor */
           "s_pTempEntities"
           {
             "windows"   "16"
           }
           "GetTEName"
           {
             "windows"   "4"
             "linux"     "4"
             "mac"     "4"
           }
           "GetTENext"
           {
             "windows"   "8"
             "linux"     "8"
             "mac"     "8"
           }
           "TE_GetServerClass"
           {
             "windows"   "0"
             "linux"     "0"
             "mac"     "0"
           }
         }
    
         "Signatures"
         {
           "CBaseTempEntity"
           {

             "windows"   "\x55\x8B\xEC\x8B\x45\x08\x89\x41\x04\xC7\x01"

         {
           /* Functions in CGlobalEntityList */
           "FindEntityByClassname"
           {
             "library"   "server"
             "windows"   "\x55\x8B\xEC\x53\x56\x57\x8B\xF9\x8B\x4D\x08\x85\xC9\x74\x2A\x8B\x01\xFF\x50\x08\x8B\x30"

           }
         }
       }
    
       /* CBaseEntityOutput::FireOutput */
       "#default"
       {
         "Signatures"
         {

           {
             "library"   "server"
             "windows"   "\x55\x8B\xEC\x81\xEC\x30\x01\x00\x00\xA1\x2A\x2A\x2A\x2A\x33\xC5\x89\x45\xFC\x53"
