 |
|
People I would like to express my appreciation to DarkByte and everyone who helped developing CE, contributing on CE forum etc. It's an excellent and inspiring tool. I especially love the built in auto-assembler which it's just a solid bliss to work with. I'm new in CE with pretty small assembly coding experience but I could already easily manage to write injections using a common memory area that's shared between different processes via Kernel32 WinAPI calls. As a CE newbie, it was stunning for me how easy it was to work with WinAPI calls in a built-in assembler/disassembler like this xD It seemed just as easy as I would do it in visual basic 
One question:
I'm completely new in Lua language and cheattables and I'd like to know what's the most effective way to automatize opening a process & inject an assembly code. I mean on my current CE level, I do it the following way:
1.) I run the process I want to inject an assembly code into.
2.) I run CE with a command line option that contains the path and name of the cheat table.
3.) I open the process in CE.
4.) I enable assembly code injection.
What's the easiest general way (if there is any) to reduce the above steps to just load a table that would make CE to wait for the process to be launched and then auto-inject an assembly code when the process appears in the process list ?
(again, I'm new in Lua and cheattables sry if this is a n00b question)

Why don't you use built-in cheat engine trainer creator ?
File -> Generate generic trainer...
On topic :
| Code: |
function rep()
timer_setEnabled(t, false);
autoAssemble([[
alloc(newmem,2048,"a.exe"+1468)
label(returnhere)
label(originalcode)
label(exit)
newmem:
originalcode:
nop
exit:
jmp returnhere
"a.exe"+1468:
jmp newmem
nop
returnhere:
]]);
object_destroy(t);
closeCE();
end
createProcess(TrainerOrigin .. "\\a.exe", "", false, false);
openProcess("a.exe");
t = createTimer(nil, false);
timer_setInterval(t, 100);
timer_onTimer(t , rep);
timer_setEnabled(t, true);
|
This is my first and last time which made a complete code because I was interested on topic.

Thanx for the quick reply, yea I studied generating trainers and Lua language, but I'm just lame, I need time  Thanx for the script that seems what I'm lookin for
May be a next version of CE could have such thing as a built in function though ...

|

Ok just a small addition to this thread to make it complete. Firstly, another thanx to Mohsen, as I'm a n00b on Lua scripting and absolutely couldn't solve this prob without his help. Here I'm adding my final and absolutely working version of the Luascript that exactly performs what I want.
The following version doesn't launch the target process but it waits for the user / another app to do it. Once the target process appears in the process list, CE will perform the injection and quits:
| Code: |
function CheckAndInject()
timer_setEnabled(t, false);
TargetProcessName = "AnyProcess.exe"
openProcess(TargetProcessName);
if getOpenedProcessID() == getProcessIDFromProcessName(TargetProcessName) then
autoAssemble([[
// ... any auto-assembler script ...
]]);
object_destroy(t);
closeCE();
else
timer_setEnabled(t, true);
end
end
t = createTimer(nil, false);
timer_setInterval(t, 500);
timer_onTimer(t, CheckAndInject);
timer_setEnabled(t, true);
|
This script can be made to include auto-launching the target process by simply inserting the line:
| Code: |
createProcess("AnyProcessPath/AnyProcess.exe", "commandline options", false, false);
|
right before the "createTimer line" of the above script.
Another interesting question I'm itching to know is that are there any limitations for the size of Lua / auto-assembler scripts ?

The limit is 2048 bytes, equal to 2KB.
You have read, write, execute permission.

You can change that to any size you want

|

Ermmm ... yes I supposed the allocated memory for the assembled codes has no limits but that's another one that good to be sure What I was really wondering was are there any size limits for the script files themselves (that contain the source code) as I tend to create pretty much big codes, but, in the meantime, as I further studied auto-assembler I found that it has include feature so I can even organize my assembly codes in modules so nevermind this question I was a goose as usual
Thanx for replying anyways

As much space as a 64 bit application can hold in memory (a lot)
