Quick Actions Toolbar — Plugin for Cheat Engine

---

Lightweight plugin for Cheat Engine that adds a compact and powerful toolbar directly into the Memory Viewer.

When working with assembly code, debugging, or reverse engineering, many commonly used actions are hidden inside context menus. This slows down workflow and makes navigation less efficient.

This plugin solves that problem by providing instant one-click access to the most frequently used Memory Viewer actions — all in one place.

• Platform: Cheat Engine (Lua plugin)

What the Plugin Does

• Quick Actions Toolbar integrates directly into the Memory Viewer (TMemoryBrowser) and adds a bottom toolbar with essential debugging and reverse engineering tools. As a result, users can access important actions much faster without navigating complex menus.

• Instead of searching through multiple context menus, you can execute actions instantly using dedicated buttons. For example, commonly used features like Break and Trace or Replace with NOP are always available in one click.

• In addition, the plugin uses original Cheat Engine menu items internally, which ensures full compatibility and native behavior. Therefore, it works seamlessly with existing functionality and other plugins.

Hey awesome script! I noticed however that with my DPI of 192 that the buttons were squished. I took a look and your script hard codes DPI's 96, 120, and 144. I could easily change one to 192 and it would work but I decided to see if I could change them to be dynamic instead. Here's what I came up with:

Old Button Code

► Show Spoiler

Code: Select all

local function createActionButton(mb)
...
  if SystemDPI == 96 then
    btn.Width  = scaleSize(spec.width + 2)
    btn.Height = scaleSize(MVQuickToolbar.ButtonHeight)
  end

  if SystemDPI == 120 then
    btn.Width  = scaleSize(spec.width)
    btn.Height = scaleSize(MVQuickToolbar.ButtonHeight)
  end

  if SystemDPI == 144 then
    btn.Width  = scaleSize(spec.width)
    btn.Height = scaleSize(MVQuickToolbar.ButtonHeight)
  end
...

New Button Code

► Show Spoiler

Code: Select all

local function createActionButton(mb)
...
  btn.Width  = scaleSize(spec.width + (SystemDPI == 96 and 2 or 0))
  btn.Height = scaleSize(MVQuickToolbar.ButtonHeight)
...

I kept SystemDPI here so if it detects 100% scaling it will still help with the cramping. It also keeps functionality to adjust scaling for different DPI's as needed. Otherwise no need for more gating logic.

Old Toolbar Code

► Show Spoiler

Code: Select all

local function buildToolbar(mb)
...
  if SystemDPI == 96 then
    MVQuickToolbar.PanelMinHeight = scaleSize(30)
    MVQuickToolbar.ButtonHeight = scaleSize(MVQuickToolbar.PanelMinHeight)
    toolbar.Height = MVQuickToolbar.PanelMinHeight + scaleSize(2)
  end

  if SystemDPI == 120 then
    MVQuickToolbar.PanelMinHeight = scaleSize(22)
    MVQuickToolbar.ButtonHeight = scaleSize(MVQuickToolbar.PanelMinHeight)
    toolbar.Height = MVQuickToolbar.PanelMinHeight + scaleSize(2)
  end

  if SystemDPI == 144 then
    MVQuickToolbar.PanelMinHeight = scaleSize(16)
    MVQuickToolbar.ButtonHeight = scaleSize(MVQuickToolbar.PanelMinHeight)
    toolbar.Height = MVQuickToolbar.PanelMinHeight + scaleSize(2)
  end
...

New Toolbar Code

► Show Spoiler

Code: Select all

local function buildToolbar(mb)
...
  local dpiBaseHeightMap = { [96] = 30, [120] = 22, [144] = 16 }
  local unscaledBaseHeight = dpiBaseHeightMap[SystemDPI] or 30

  MVQuickToolbar.ButtonHeight = scaleSize(unscaledBaseHeight)
  MVQuickToolbar.PanelMinHeight = MVQuickToolbar.ButtonHeight

  toolbar.Height = MVQuickToolbar.ButtonHeight
...

Again kept SystemDPI for custom scaling purposes. I also made a little table to map DPI to BaseHeight so it wouldn't be as wordy when we try to calculate more than 3 k v pairs; You can add something like it for the button code if you need it as well. I kept it at 30 for everything above 144 DPI because I think it looks quite nice. However I'm not able to view it under different DPI's to test because mine is stuck for some reason but the logic should be sound. Hope this helps any peeps that had the same problem.
