Man, i has stuck!
Well, i started programming with cheat engine recently and i want create script to change adresses already defined, in the adress list.

For example, i have 100 gold and 5 strength. I find the gold, strenght adress and i create a point adress. Now, every time when i start the game the research for gold and strength is not needed, this thing is ok, but how i use already searched point adress like a variable in my script?

And next, i want create a new thing: Every time if i have 100 gold, i earn 1 strenght and my gold turns 0.

How i do this?

Since you're asking in the lua scripting section I'll focus on that.

Most lua functions take an address, so if it's a pointer like "game.exe+550" with an offset of 4 and an offset of 8 (or a static address, just want to demonstrate multilevel pointers) then you can can use something like this as the address "[[game.exe+550]+4]+8" (the [] tell lua to read the value at that address in memory as an address/pointer before continuing), eg.

Code:
[ENABLE]
{$lua} -- switch parser to lua instead of assembly

writeInteger("[[game.exe+550]+4]+8", 100) -- write 100 to address given

-- note any string returned will be parsed as if it was code in the asm script
{$asm} // switch back to assembly parser

[DISABLE]
// do nothing


So to change 100 gold into 1 strength you could do something like this:

Code:
[ENABLE]
{$lua}
goldAddr = address of gold
strAddr = address of strength

gold = readInteger(goldAddr)

-- assuming 4 byte values, aka "integer"
if gold > 100 then
  writeInteger(goldAddr, gold-100)
  writeInteger(strAddr, readInteger(strAddr)+1)
end
{$asm}

[DISABLE]


If you want it to happen automatically instead of having to enable the script every time then you could create a timer eg.


Code:
[ENABLE]
{$lua}
goldAddr = address of gold
strAddr = address of strength
mr = getAddressList().getMemoryRecordByDescription("name/description of script")
timer = createTimer()

-- set code to run
timer.OnTimer = function(timer)
  -- check if the script has been disabled
  if not mr.Active then
    timer.destroy() -- stop the timer
    return -- don't execute the rest of this code
  end
 
  -- script still enabled so read gold value
  -- assuming 4 byte values, aka "integer"
  gold = readInteger(goldAddr)
 
  -- check if gold is greater than or equal to 100
  if gold >= 100 then
    -- subtract 100 from gold amount and increase strength amount by 1
    writeInteger(goldAddr, gold-100)
    writeInteger(strAddr, readInteger(strAddr)+1)
  end
end

-- set time delay between code being run
timer.Interval = 1000 -- 1000 milliseconds / second, so every second
{$asm}

[DISABLE]
