This is an auxiliary tool for finding pointer methods in the ce tutorial.
The problems encountered before
The ai gave this answer.
It has not been tested yet to see if it can be used
There is no game testing at present.
If you have encountered this problem, you can try using this tool to test whether it can be used.

Features of This Script:

1 Monitors address access in real-time using breakpoints

2 Automatically deletes unaccessed addresses after monitoring completes

3 No confirmation dialogs - deletion happens immediately

4 Progress tracking with visual progress bar

5 Real-time statistics showing accessed vs. unaccessed addresses

6 Manual deletion option at any time

Usage Instructions:

1 Attach Cheat Engine to the target process

2 Perform a memory scan to populate the address list

3 Click "Start Monitor" to begin monitoring

4 Interact with the target program to trigger memory accesses

5 After monitoring completes, unaccessed addresses will be automatically deleted

6 Alternatively, click "Delete Unaccessed Now" to manually delete at any time

This script is particularly useful for narrowing down memory scans by eliminating addresses that aren't actually being accessed by the program during your monitoring period.

Interesting idea. How is performance when you have 1M+ addresses in the list?

This is used after the step of "finding out what accessed this address",Search for the most likely value， and there are at most only a few thousand addresses

I believe this delete reference is undefined.
Assuming you've tried this code, did you define it elsewhere?

Code:

foundList.Items.delete(index)

Examine the following code to simulate a real deletion:

Code:

local fl = getMainForm().Foundlist3

local function getRemoveSelectedMenuItem(listview)
local pm = listview.PopupMenu
if not pm or not pm.Items then return nil end
for i=0, pm.Items.Count-1 do
if pm.Items[i].Name == "Removeselectedaddresses1" then
return pm.Items[i]
end
end
return nil
end

local miRemove = getRemoveSelectedMenuItem(fl)
assert(miRemove, "Could not find Removeselectedaddresses1 menu item")

local function removeUnreadableOrChanged(listview, removeMenuItem)
-- all line unselect
for i=0, listview.Items.Count-1 do
listview.Items[i].Selected = false
end

-- check
for i=0, listview.Items.Count-1 do
local item = listview.Items[i]
if item then
local address = item.Caption
local value = item.SubItems[0]
local previous = item.SubItems[1]

local unreadable = (value == "???") or not item
local changed = (not unreadable) and (value ~= previous)

if unreadable or changed then
if unreadable then
print("Unreadable: "..address.." Value="..tostring(value).." Previous="..tostring(previous))

item.Selected = true
else
print("Changed: "..address.." Value="..tostring(value).." Previous="..tostring(previous))
end

end
end
end

-- selected (unreadable) delete
removeMenuItem.DoClick()
end

-- execute
removeUnreadableOrChanged(fl, miRemove)

-- or

Code:

local fl = getMainForm().Foundlist3

-- Menu search ..
local function getRemoveSelectedMenuItem(listview)
local pm = listview.PopupMenu
for i=0, pm.Items.Count-1 do
if pm.Items[i].Name == "Removeselectedaddresses1" then
return pm.Items[i]
end
end
end

local miRemove = assert(getRemoveSelectedMenuItem(fl), "Menu item not found")

-- Wrapper fonksiyon
function deleteItem(listview, index)
if listview.Items[index] then
listview.Items[index].Selected = true
miRemove.DoClick()
end
end

-- use
deleteItem(fl, 1)

When experimenting on a certain Unreal game, it popped up that the debugger could not be attached. The code that could barely run in previous ce versions also reported the same error. The ai had no idea why, and Google had no result. It ended before it even began.

You should first give it CE Defines and celua.txt. Things that AI does well: It organizes existing and complex code very well (grids and Lua modeling). It finds very good and global function names. (I often ask it for the module or function name. ). It performs calculations very well. It has good calculations and ideas in lines of code that require mathematics. When I create a code or module, I have it write which line, function, and what it does, and the inline comments. (It never gets tired of doing this. ) Formulate the idea, write the code, test and organize step by step, and only leave the cleanup to AI at the end. _________________ Hi Hitler Different Trainer forms for you! https://forum.cheatengine.org/viewtopic.php?t=619279 Enthusiastic people: Always one step ahead Do not underestimate me Master: You were a beginner in the past
