I got this from IDA:

PHP Code:

(*(*debugoverlay + 12))(debugoverlay, &v20, &v22, 255, 0, 0, 1, 0x41200000); // 0x41200000 = 10.0
// DebugOverlay(debugoverlay, Vector&, Vector&, int, int, int, bool, float) 


And gamedata:

Spoiler

PHP Code:

"Games"
{
    "left4dead2"
    {
        "Addresses"
        {
            "DebugOverlayPtr"
            {
                "linux"
                {
                    "signature"  "DebugOverlay"
                }
            }
        }
        "Signatures"
        {
            "DebugOverlay"
            {
                "library"   "server"
                "linux"      "@debugoverlay"
            }
        }
    }
} 


How to make a sdkcall for the function above if I got the address of "debugoverlay" ?

not test.

PHP Code:

Address debugoverlay = LoadFromAddress(hGameData.GetMemSig("debugoverlay"), NumberType_Int32);
Address debugoverlay_func = LoadFromAddress(debugoverlay + view_as<Address>(12), NumberType_Int32);

// sdkcall_raw
SDKCall(g_hSDKCall_Debugoverlay, debugoverlay_func, v20, v22, 255, 0, 0, 1, 0x41200000);

还是不对，不过不重要了，我确定了这个东西没法在服务器端使用，除了本地服，在本地服还不如直接 用 drawline。

Failed. But not important any more, because I confirm that "debugoverlay" couldn't use on server side except local server. Use "drawline" on local server is enough.
