I have some addresses the show the profession of a hero. ie.
Description Address Value
Hero 1 Profession 07115C98 7
Hero 4 Profession 07115C9B 1
The value of 7 is a Ninja, 1 Solder etc.
How can I code the description to read Hero 1 Profession is Ninja when the value is 7?

Code:

value=readInteger(0x07115c98)

if value==1 then
  description='Soldier'
end

if value==7 then
  description='Ninja'
end

descriptionofhero1label.caption=description

you can easily adapt this to hero 4 as well

If this isn't a lua question but just an addresslist question, then look into the dropdown list

That would work, if the addresses were static, but they change every time the game opens. I have a recalculation function in the CE panel I have.
I was thinking a for loop after
Code:

   prof1address = addresslist_getMemoryRecordByDescription(addresslist, "Hero 1 Profession")
   prof1 = memoryrecord_getValue(prof1address)
   prof2address = addresslist_getMemoryRecordByDescription(addresslist, "Hero 2 Profession")
   prof2 = memoryrecord_getValue(prof2address)
...
   prof20address = addresslist_getMemoryRecordByDescription(addresslist, "Hero 20 Profession")
   prof20 = memoryrecord_getValue(prof20address)
for x = 1, 20 do
      whichprof = "prof"..x
      if whichprof == 1 then
        memoryrecord_setDescription(prof1address, "Soldier")
      elseif whichprof == 2 then
        memoryrecord_setDescription(prof1address, "Knight")
      etc.
      end
end

My obstacle is how to code in the hero number with the specific profession

Hi, I've generalized the idea with these function:

Code:
local conv_rules = {
  -- numeric key
  class={[1]="witch",[2]="knight",[0xf]="monomaneshi"},
  -- string key, case matter, key name follow lua variable naming rule,ie. no space etc.
  name={john="John Lennon", paul="Paul McCartney", george="George Harrison", yoko="Yoko Ono"}
}

local convert = function (mr,d)
  local desc = mr.Description
  for k,v in pairs(d) do
    local mkey = '@'..k..':'  -- adapt for your header format
    local head = string.sub(desc, 1, #mkey)
    if mkey == head then
      local val = v[tonumber(mr.Value)] or v[tostring(mr.Value)]
      if val ~= nil then
         mr.Description = mkey..val
      else
         mr.Description = mkey..'???' -- adapt for your unknown value identifier
      end
      break
    end
  end
end

local updateAddrList = function(d)
  local d = d or conv_rules
  local al = getAddressList()
  for i=0,al.Count-1 do convert(al[i],d) end
end

updateAddrList()


Customize the 'conv_rule' then manually set the description 'header' to let the function know which type (class or name in above example) the memory record should set.

Attach the 'updateAddrList' to a timer function event may let it update automatically.

Many questions
First:
class={[1]="witch",[2]="knight",[0xf]="monomaneshi"}, Why the 0xf? why the comma at the end?
Second:
local convert = function (mr,d) What is d and when, how is it enabled?
Third:
local desc = mr.Description Which memory record does this refer?
Fourth:
local mkey = '@'..k..':' -- adapt for your header format Why the @ char. and why the : char. k I assume would be the class (name does not fit the general game as names are not constant)
Fifth:
local head = string.sub(desc, 1, #mkey) Where does the # mean?
Sixth:
local d = d or conv_rules I don't understand this statement. Please explain your process.
Seventh:
local updateAddrList = function(d) Same question where does d come from in the code

I tried a snippet of your code:
Code:
local conv_rules = {
  -- numeric key
  class={[1]="Soldier",[2]="Knight",[3]="Berzerker",[4]="Unknown",[5]="Unknown",[6]="Unkown",[7]="Ninja",[8]="Beast Master",[9]="Unknown"}--[0xf]="monomaneshi"},
}

local convert = function (mr,d)
  local desc = mr.Description
  print(desc)
  for k,v in pairs(d) do
    local mkey = '@'..k..':'  -- adapt for your header format
    print(mkey)
    local head = string.sub(desc, 1, #mkey)
    print(head)
    if mkey == head then
      local val = v[tonumber(mr.Value)]
      if val ~= nil then
         mr.Description = mkey..val
      else
         mr.Description = mkey..'???' -- adapt for your unknown value identifier
      end
      break
    end
  end
end

local updateAddrList = function(d)
  local d = d or conv_rules
  print(d)
  local al = getAddressList()
  --for i=0,al.Count-1 do convert(al[i],d) end
end

Nothing happens

I'm not English Speaking native, and not good at explaining, I answer briefly. It is better have a look at official Lua for basic of Lua, ce use ver 5.1, so check here

Quote:
First:
class={[1]="witch",[2]="knight",[0xf]="monomaneshi"}, Why the 0xf? why the comma at the end?

'0xf' is hexadecimal representation of number 15, just for an example of numeric key usage. The comma is used to separate different key-value pairs, it is a lua syntax.

Quote:
Second:
local convert = function (mr,d) What is d and when, how is it enabled?

It is a parameter for the function. You supply the parameter when calling the function.

Quote:
Third:
local desc = mr.Description Which memory record does this refer?

This function will be call for every memory record on the address list, by specifying the mr as 1st parameter of the function, so every memory record.

Quote:
Fourth:
local mkey = '@'..k..':' -- adapt for your header format Why the @ char. and why the : char. k I assume would be the class (name does not fit the general game as names are not constant)

It is just a format to let the function know which conv_rules should be use on the memory record.

Quote:
Fifth:
local head = string.sub(desc, 1, #mkey) Where does the # mean?

It is the number of byte of the string the variable mkey holding, in this case same as number of characters in the string.

Quote:
Sixth:
local d = d or conv_rules I don't understand this statement. Please explain your process.

You can supply no parameter (d) for the updateAddrList function, in this case, it use a default d, as conv_rules.

Quote:
Seventh:
local updateAddrList = function(d) Same question where does d come from in the code

It is an optional function parameter, see previous.

Here steps on using the function:
1. paste the functions on lua script editor by tool/'show cheat table lua script'
2. customize the conv_rules
3. setup your address list, this part you have to do it your self on your game target
4. manually change the description by double click the column. That's, if the address entry's value represent a weapon, and the description name should follow the 'weapon' conv_rules, set the 1st few characters of the description as "@weapon:".
5. execute the script.

You did very well with English, far better than I with your language.
I copied the entire code you presented (plus some print statements) except updateAddrList(), then entered updateAddrList() in the debug window and got
Error:[string "updateAddrList()..."]:1: attempt to call global 'updateAddrList' (a nil value)

updateAddrList is defined locally.
delete the 'local'.

Yes, as DaSpamer said.

Quote:
... OK, but the name function won't work for the general case as the names change every time the game starts


You mean the ADDRESS of the value representing 'name' change?

If it is the 'name' change, or the relationship between the 'name' and the value representing 'name' change every game start, yes, it won't work.

For example, the value of an address is the item_index, and you know from game playing that the item_index represent an item having an in-game name item_name, the relationship between list of item_index and item_name should normally not change every game start.
Otherwise you cannot customize the conv_rules.

If it is the Address of the item_idx change, then it is up to you to setup the CE AddressList. I cannot do anything without further knowledge of the game and your exact goal want to achieve.

You mean the ADDRESS of the value representing 'name' change? The addresses all change every time the game opens, I have a recalculation function to get table addresses in synch with the game.

If it is the 'name' change, or the relationship between the 'name' and the value representing 'name' change every game start, yes, it won't work.The names change every time the game initiates, but after that the names remain the same

For example, the value of an address is the item_index, and you know from game playing that the item_index represent an item having an in-game name item_name, the relationship between list of item_index and item_name should normally not change every game start.
Otherwise you cannot customize the conv_rules.The values are probably in the game data, but values always mean the same profession 1 for Soldier, 2 for Knight et.c

If it is the Address of the item_idx change, then it is up to you to setup the CE AddressList. I cannot do anything without further knowledge of the game and your exact goal want to achieve.

That is what I did, still have the same error.
Code:
 updateAddrList = function(d)
   local d = d or conv_rules
   local al = getAddressList()
   for i=0,al.Count-1 do convert(al[i],d) end
 end
--updateAddrList()

Finished the coding with long if statements, but it does work.
For the code to work all the time I need one more step.
Here is a bit of the code with questionable steps commented out currently:
Code:

   self.form.show();

   --self.form.close(CloseCET)
   --self.profession.Enabled = false
Shut down the timer used to re-write professions within the trainer so self = trainer
Code:

   --function CloseCET(sender)
      --local addresslist = getAddressList()
      --memoryrecord_setDescription(prof1address,"Hero 1 Profession")
      --memoryrecord_setDescription(prof2address,"Hero 2 Profession")
      --memoryrecord_setDescription(prof3address,"Hero 3 Profession")
      --memoryrecord_setDescription(prof4address,"Hero 4 Profession")
      --memoryrecord_setDescription(prof5address,"Hero 5 Profession")
      --memoryrecord_setDescription(prof6address,"Hero 6 Profession")
      --memoryrecord_setDescription(prof7address,"Hero 7 Profession")
      --memoryrecord_setDescription(prof8address,"Hero 8 Profession")
      --memoryrecord_setDescription(prof9address,"Hero 9 Profession")
      --memoryrecord_setDescription(prof10address,"Hero 10 Profession")
      --memoryrecord_setDescription(prof11address,"Hero 11 Profession")
      --memoryrecord_setDescription(prof12address,"Hero 12 Profession")
      --memoryrecord_setDescription(prof13address,"Hero 13 Profession")
      --memoryrecord_setDescription(prof14address,"Hero 14 Profession")
      --memoryrecord_setDescription(prof15address,"Hero 15 Profession")
      --memoryrecord_setDescription(prof16address,"Hero 16 Profession")
      --memoryrecord_setDescription(prof17address,"Hero 17 Profession")
      --memoryrecord_setDescription(prof18address,"Hero 18 Profession")
      --memoryrecord_setDescription(prof19address,"Hero 19 Profession")
      --memoryrecord_setDescription(prof20address,"Hero 20 Profession")
   --end--function CloseCET(sender)

What I'm attempting is to re-set the professions back to the original when CE is shut down. There should be one more step in the code:
To Save The Table.

Is this the correct syntax and what would be the correct saving code?

Perhaps it might be easier to just build the cheat table with the lua script and on save delete all entries so only the lua script remains ? (or just don't save at all)

Hi,
I've made a tutorial on response to "save the table" here

Copy the necessary function and get the menuitem 'save', use as the usage after where the table/address is just updated .
