Spiral Knights

[Jaerin]

So I'm attempting to dissect the game Spiral Knights and I'm having a lot of trouble finding static pointers to various memory structures. I have no problems finding my current health in memory but I can't seem to consistently be able to get a static pointer to it.

I'm a complete noob and have never created anything from scratch. At this point I'm just trying to create a dashboard that will read various memory locations and give more detailed information about heath, heat gained, crowns, ect...

I've found several tutorials on how to use the Cheat Engine Pointer Scanner to track them down, but I'm having no luck. It seems like as long as I'm logged in and I zone to cause the address to move I can find a static pointer to it, but if I log out of the game and log back in I can't find it again. I think part of the issue might stem from the fact that this game is actually a Java game so the only process to attach to is javaw.exe. Also the pointer scanner doesn't seem to return any reference to an .exe only to various dll's that are loaded.

Any tips on rooting it out?

Good news I found a static pointer to Current HPs. I used Cheat Engines pointer scanner and I had to go 6 deep to find it.

"javaw.exe"+00018E38+30+374+78+C+F0+78

Now that I have this I'm wondering how to translate this into code that I can use say with blackmagic or something. I'm starting simple, the health number is exact unlike in game its a bar. I'd like to create an app that will display the exact health value. I'd also ultimately like to be able to set a certain health threshold to play a sound. I've suggested a warning sound for low health, but it has gone unanswered so far.

Okay they patched and I actually create an autoit script to do a low health warning. I'm still working on making it better.

I really wish I could read the structures better. I think I've found the items in my inventory, and if I could pick apart resistances it would be HUGE. The theorycrafters would have a hayday over being able to see the actual numbers behind the bars. I've already found that health is measured in 40 hp per bar and damage is decimal in nature even though everything is hearts and bars in the game.

#include <NomadMemory.au3>

SetPrivilege("SeDebugPrivilege", 1) 

If WinExists("Spiral Knights") = 0 Then
    MsgBox(0, "", "Application is not running. Please run it before starting this app.")
    Exit
EndIf

$pid = ProcessExists("javaw.exe")
$StaticOffset = Dec("19460")

while 1
Global $Offset[7]
$Offset[0] = 0
$Offset[1] = Dec("DC")
$Offset[2] = Dec("150")
$Offset[3] = Dec("77C")
$Offset[4] = Dec("634")
$Offset[5] = Dec("F0")
$Offset[6] = Dec("78")
$openmem = _MemoryOpen($pid)
$baseADDR = _MemoryGetBaseAddress($openmem, 1)
$finalADDR = "0x" & Hex($baseADDR + $StaticOffset)
$MemPointer = _MemoryPointerRead($finalADDR, $openmem, $Offset)
_MemoryClose($openmem)

$CurHP = $MemPointer[1]

If $CurHP < 180 then SoundPlay( "LowHealth.wav", 1 )
	
WEnd

If anyone is interested in helping dig into this please shoot me a PM.

Sigh this still isn't reliably static. After a few relogs the pointer stopped working again.

I've found a number that point to various DLL's but I haven't figured out how to get Autoit to give the pointers yet. The MemoryGetModuleBaseAddress function doesn't seem to be working for this game.

I'll keep trying
