in AA :
Code:
mov [myaddress],edx
//edx=7

//  so [myaddress] = 7
when I go to  add address manually and add [myaddress] I see its value 7
→ thats good

but in Lua script
Code:
x=7
registerSymbol(x)

//when I go to  add address manually and add [x] I see its value ????? nothing

how to fix that ?
I am trying to make complicated equations with Lua then write the equation to an address then use that address in my AA script

As the celua.txt (and presumably the wiki I never use) says

Code:
registerSymbol(symbolname, address, OPTIONAL donotsave): Registers a userdefined symbol. If donotsave is true this symbol will not get saved when the table is saved


In lua registerSymbol takes a symbol name and an address eg.

Code:
registerSymbol("xSymbolName", xAddressValue)


However in CE 6.7 you can use lua to calculate symbols in AA pretty easily, here's an arbitrary example

Code:
{$lua}
function calcAddr()
  return readPointer('Tutorial-i386.exe+1FD5D0')+0x400+math.pow(2,7)
end
{$asm}
 
[ENABLE]
$calcAddr():
{$lua}
return "dd " .. math.random(-80,80)

[DISABLE]
$getAddress('[Tutorial-i386.exe+1FD5D0]+480'):
  dd #100


both, as you might expect write to [Tutorial-i386.exe+1FD5D0]+480 (017801C0 during my testing) which is the pointer for step 2 of the tutorial.
