I need make a script cheat that can do that:
Search for a value:
62 06 66 ?? ?? 24 03 a1 4f ?? ?? ?? d0 4f ?? ?? ?? d0 4f ?? ?? ?? 47
Write this value
Change the value by:
62 06 66 ?? ?? 24 03 a1 4f ?? ?? ?? 02 02 02 02 02 02 02 02 02 02 47

Then make another script that can unchange the value:
62 06 66 ?? ?? 24 03 a1 4f ?? ?? ?? 02 02 02 02 02 02 02 02 02 02 47
>
62 06 66 ?? ?? 24 03 a1 4f ?? ?? ?? d0 4f ?? ?? ?? d0 4f ?? ?? ?? 47
(value written)

Someone know how do that? The cheat engine have the option to read a value? If not, someone know a similar program that can do that?

Not lua, but an AA command (easier, but lua can do it as well)
Code:

[enable]
alloc(originalbytes,10)
registersymbol(originalbytes)

label(foundaddress)
registersymbol(foundaddress)

aobscan(found, 62 06 66 ?? ?? 24 03 a1 4f ?? ?? ?? d0 4f ?? ?? ?? d0 4f ?? ?? ?? 47)

found+c:
foundaddress:

//store the original bytes
originalbytes:
readmem(foundaddress, 10)

//change the bytes
found+c:
db 2,2,2,2,2,2,2,2,2,2

[disable]
foundaddress:
readmem(originalbytes, 10)

unregistersymbol(foundaddress)
dealloc(originalbytes)


You can assign it to a cheat table and just toggle it on/off

bugbypass:
Before clicking assign to table go to memory view->view->userdefined symbols and add foundaddress with address 00400000

Thanks, but this don't work...
The search found two values, i guess that i need put two scripts and not unregister, right? i don't know how make a script to change two values.
And the (originalbytes), i don't need add they too in the userdefined symbols?

I don't understand the script, the readmem read the value in the 'foundadress', but why i call 'originalbytes' when disable?

For multiple you will need lua
Code:

function replaceAOB()

  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
      resultlist=nil
      resultlist={}
      for i=0,c-1 do
        a=strings_getString(r,i);
        resultlist[i+1]={}
        resultlist[i+1][1]=a  --store the address
        resultlist[i+1][2]=readBytes(a, 23, true) --store the original bytes     

        --6.1 has an ugly bug with writeBytes using a tableformat so I have to use an ugly workaround...
        for j=12,22 do
          writeBytes(tonumber("0x"..a)+j, 2)
        end


      end
      print("Found "..c.." results")
    else
      print("No results");
    end
  else
    print("Scan error")
  end

end

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


call replaceAOB() to replace the entries and call restoreAOB() to restore the entries.

You can add it to a cheat table by adding a header or other useless entry, and registering an onActivate event with memoryrecord_onActivate which then calls replaceAOB()

Ask if you wish to do that

Sorry, i don't know how do that. I add the lua command in table -> show cheat table lua script? and how i make the header? table -> create form?
i'm beginner to programming in cheat engine, i only know how search the aobs, and copy and paste scripts to make trainers. xD
If you can post me the ct with the script i'm grateful...
I'm newbie... T_T

Here is a table with this implemented
The code that's inside it:
Code:


function replaceAOB()

  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
      resultlist=nil
      resultlist={}
      for i=0,c-1 do
        a=strings_getString(r,i);
        resultlist[i+1]={}
        resultlist[i+1][1]=a  --store the address
        resultlist[i+1][2]=readBytes(a, 23, true) --store the original bytes

        --6.1 has an ugly bug with writeBytes using a tableformat so I have to use an ugly workaround...
        for j=12,22 do
          writeBytes(tonumber("0x"..a)+j, 2)
        end


      end
      --print("Found "..c.." results")
    else
      print("No results");
    end
  else
    print("Scan error")
  end

end

function restoreAOB()
  for i=1,#resultlist do
    --print("restoring result "..i)
    local a=tonumber("0x"..resultlist[i][1])
    local orig=resultlist[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
    replaceAOB()
  end

  return true
end

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

  return true
end

al=getAddressList()
--mr=addresslist_getMemoryRecordByDescription(al,"Replace stuff")
--In this specific cheat table the ID number of 0, only if you delete the entry it will change (moving has no effect)
mr=addresslist_getMemoryRecordByID(al,0);


memoryrecord_onActivate(mr,activatetick)
memoryrecord_onDeactivate(mr,deactivatetick)


don't hesitate to ask if you have questions

also, when loading the table you will get asked to execute the script, answer yes else ticking the button will not work.

5.6.1 can not make a trainer with this, you will have to use 6.1 to make the trainer (don't forget to assign hotkeys before autogenerating the trainerscript, give the trainer an icon, and do not touch the about text)

If you follow these things: give the trainer an icon, and do not touch the about text , then the trainer will open

You make a header by rightclicking the addresslist and choose Create Header

Also, if your description is unique, you can make use of mr=addresslist_getMemoryRecordByDescription(al,"Unique Description") instead of trying to find the ID
