Hey everyone,

I have a pointer to an array of pointers to int32's that I added manually to the address list and I would like to iterate through it by incrementing one of the offsets by 8 bytes at a time. Is there a way to do this in Cheat Engine and have it export the value pointed to by the pointer to a CSV table (or any other format)?

How long is the array?

This example code assumes the memory record has 4 offsets, the third offset from the base address (2nd from the top) is the one that changes, the memory record points to the first element in the array, and the array's length is 10.
Code:
local mr = AddressList.getMemoryRecordByDescription'My array'
assert(mr and mr.OffsetCount == 4)

local baseAddressStr, offsets = mr.getAddress()

local node = readPointer(baseAddressStr)
assert(node and node ~= 0)

-- last offsets in table are closest to the base address
for i in 4, 3, -1 do
  node = readPointer(node + offsets[i])
  assert(node and node ~= 0)
end

local values = {}

-- array length is 10 (bounds are inclusive)
for i in 0, 9 do
  local offset = offsets[2] + i * 8
  local addr = readPointer(node + offset)
  assert(addr and addr ~= 0)

  -- don't dereference last offset- it's the address of the integer we want
  addr = addr + offsets[1]

  -- `readInteger` can take a second parameter. If true, interpret value as signed
  local val = readInteger(addr, true)

  -- could do string formatting here, e.g. if you wanted it in hex
  values[#values+1] = val
end


local csv_str = table.concat(values, ',')

writeToClipboard(csv_str)
