Cheat Engine

[the rose]

my ctrainer.exe in lua, appears to run :Error:Access violation.
I am using, the following script:

function replaceAOB1()

r=AOBScan("62 06 66 ?? ?? 24 03 a1 4f ?? ?? ?? d0 4f ?? ?? ?? d0 4f ?? ?? ?? 47")


if (r~=nil) then
c=strings_getCount(r)
if (c>0) then
resultlist1=nil
resultlist1={}
for i=0,c-1 do
a=strings_getString(r,i);
resultlist1[i+1]={}
resultlist1[i+1][1]=a
resultlist1[i+1][2]=readBytes(a, 23, true)

for j=12,21 do
writeBytes(tonumber("0x"..a)+j, 2)
end


end

else
print("No results");
end
else
print("Scan error")
end

end

function restoreAOB1()
for i=1,#resultlist1 do
local a=tonumber("0x"..resultlist1[i][1])
local orig=resultlist1[i][2];
for j=12,22 do
writeBytes(a+j,orig[j])
end
end
end

function activatetick(mr, before, currentstate)
if (before==false) and (currentstate==true) then
replaceAOB1()
end

return true
end

function deactivatetick(mr, before, currentstate)
if (before==false) and (currentstate==false) then
restoreAOB1()
end

return true
end

al=getAddressList()
mr=addresslist_getMemoryRecordByID(al,0);
memoryrecord_onActivate(mr,activatetick)
memoryrecord_onDeactivate(mr,deactivatetick)

-----------------------------------------------------------------------
this error in my script? or will be a bug in the cheat engine?

thank you

Test it without saving it as a .exe, add some debug prints and execute the script yourself

Also, if that is all of the script, it won't work. there is no command to open the process

[the rose]

I put the command to open the process.

was thus:

function myattach(timer)
if getProcessIDFromProcessName("Transformice.exe") ~= nil then
object_destroy(timer)
openProcess("Transformice.exe")
end
end

t=createTimer(nil);
timer_setInterval(t,100)
timer_onTimer(t,myattach)

function replaceAOB1()

r=AOBScan("62 06 66 ?? ?? 24 03 a1 4f ?? ?? ?? d0 4f ?? ?? ?? d0 4f ?? ?? ?? 47")


if (r~=nil) then
c=strings_getCount(r)
if (c>0) then
resultlist1=nil
resultlist1={}
for i=0,c-1 do
a=strings_getString(r,i);
resultlist1[i+1]={}
resultlist1[i+1][1]=a
resultlist1[i+1][2]=readBytes(a, 23, true)

for j=12,21 do
writeBytes(tonumber("0x"..a)+j, 2)
end


end

else
print("No results");
end
else
print("Scan error")
end

end

function restoreAOB1()
for i=1,#resultlist1 do
local a=tonumber("0x"..resultlist1[i][1])
local orig=resultlist1[i][2];
for j=12,22 do
writeBytes(a+j,orig[j])
end
end
end

function activatetick(mr, before, currentstate)
if (before==false) and (currentstate==true) then
replaceAOB1()
end

return true
end

function deactivatetick(mr, before, currentstate)
if (before==false) and (currentstate==false) then
restoreAOB1()
end

return true
end

al=getAddressList()
mr=addresslist_getMemoryRecordByID(al,0);
memoryrecord_onActivate(mr,activatetick)
memoryrecord_onDeactivate(mr,deactivatetick)

works as .ct

as .exe (display the following error)

An unhandled exception occured at $0042208f:
Edecompressionerrror: buffer error

(I can not create a cttrainer.exe in the moon)

[Dark Byte]

save your trainer with a lesser level of compression (or none at all) and then test it.
If the size is an issue, then compress the generated exe yourself

[misha-cs]

I'm making a trainer in the format .exe, where i'm using debug functions (ondebagger, pause, unpause). During the functions activation there is a mistake:

[Dark Byte]

Yes, there is a bug in cheat engine 6.2 regarding pause/unpause in protected trainers. Because it is protected some gui elements have been destroyed, but pause/unpause make use of that without checking if they exist or not

See if you can do an alternate method of pause. (speedhack speed 0, or set a breakpoint and wait for it to trigger)

[misha-cs]

Thanks! I do it!

what does this error mean?
Error:[string "autoAssemble([[aobscan(bla, 89 08 8B 0D ?? ..."]:13: attempt to call global 'autoAssamble' (a nil value)

[Mohsen]

This means autoAssamble is not found..
Post your while script if possible

[shadowwolf]

ok, i`ll try it out, hope it works with some changes
