Debug Text

This document is a work-in-progress and may be missing information.

This is a developer hack that can be enabled on the "Developer" page of the Mods List.

This hack displays various debugging information via a series of pages that can be navigated with the R and T keys (or Shift+R and Shift+T for subpages).


Mods can customise the font Debug Text uses by loading a Texture Font chunk named DebugText.

Command Line Arguments

This hack is affected by certain Command Line Arguments for the Mod Launcher.

Version History


  • Fixed an issue where the "×" symbol in the title of the "Graphics > Allow Textures Larger Than 2048 × 2048" setting was the wrong character in some non-unicode system locales.
    • For example, it appeared as "Ч" in Russian.
  • Added a new "walker cam" page.



Added a list of cars that will be removed the next time they're off screen to both the "cars" and "mission" pages.

"mission" Page

  • Made it so this page now shows which stages have checkpoints and which stage is currently the active checkpoint.
  • Changed "active" to "current" when indicating what stage you're currently on.
  • Made it so this page now shows the current state of a stage.
    • A stage's state can be "active", "completed" or "failed".
    • A stage's state can also be nothing.
  • Made it so this page now shows what stage vehicles are being manipulated in each stage.
    • This shows what locator and AI the vehicle is being added and/or activated with.
  • Made it so this page now shows a list of every stage vehicle used in the mission.
    • This list shows whether or not the vehicle is currently in the world.
    • This list also shows the driver of the vehicle and also whether or not the driver is in the world.
    • Cars are removed from this list when the mission is done using them.


Renamed the -debugtextmode command line argument to -debugtextpage to be more consistent with the hack's settings.

The old is still supported for backwards compatibility.


"cars" Page

Added information about husks.


"anim entities" Page

Added this new page. This shows "D arrow anims", "W arrow anims", "Anims", "Anim colls", "Multi controllers" and "State props".


"position" Page

Made this page show all action buttons the player is in with "(main)" after the main one (the one you can interact with) instead of just showing the main one.


"AI cars" Page

Added this page.

"car physics objects" Page

Added this page.

"fences" Page

Fixed an issue introduced in 1.23.2 where switching to this page broke anything that was one-sided.

Frame Limiter

Fixed an issue where mission loading screens (used when selecting a mission or starting one) were considered menus instead of loading screens.



  • Added a "keyboards" page, a "mice" page and a "steering wheels" page to a new "controllers" group.
  • Moved the "gamepads" page to the new "controllers" group.

"fences" Page

Fixed a bug where this page didn't set the cull mode before rendering the fences (causing the fences to only be visible from one side in some cases).

"mission" Page

Fixed a crash when a stage condition is null (which will crash the game when reaching the stage).

"music" Page

Fixed a crash when using the game's "MUTE" command line argument (which is enabled by the new No Audio mod).



Added a new "gamepads" debug mode.



  • Made debug class names cleaner. For example ".?AVVehicle@@" will now show up as "class Vehicle".
  • Added a -debugtextmode command line argument. This can be used to launch the game with a specific debug mode enabled.
  • Added a -noscaledebugtext command line argument. This disables the debug text being scaled according to the size of the window.
  • Made the debug text scale down to fit the screen.
    • Also added a -nofitdebugtext command line argument to disable this.
  • Made it so pages that are not built in are grouped by what Mod/Hack added them.
    • Grouped pages can be cycled by holding Shift+T/Shift+R.
    • Also added a -nodebugtextgroups command line argument to disable this.
  • Made the "traffic" and "road segments" pages show intersections as blue spheres in the world as well as their names.
  • Removed the "root tree node and animated icons" page and moved its contents to the "tree" and "miscellaneous" pages respectively.

"miscellaneous" Page

  • Added "Action buttons" to show the amount of action buttons that exist out of the maximum.
  • Added "Playing sound clip players" and "Playing sound stream players" which show the current amounts out of the maximums.

"cars" Page

  • Added "Parked car count" to show how many parked cars currently exist.
  • Moved the listed traffic cars to the "traffic" page.

"mission" Page

  • Now shows "Time" in stages with a timer. This is shown in milliseconds.
  • Now shows the current time and duration on "timer" objectives in milliseconds.

"traffic" Page

  • Added "Count" to show the amount of traffic cars currently in existence out of the maximum.
  • Added "In-car limit" to show what the in-car limit is currently set to.
  • Added "Group" to show what traffic group is currently in use.
  • Added a list of all models in the current traffic group with the current amount of each one out of their maximum.
  • Added a list of all current traffic cars and whether or not they're active (in the world).

"music" Page

Fixed a crash when viewing this page when the current region had multiple layers in it.

"paths" Page

  • Made this page only show the models of the current ped group and not show an "x" after each count.
  • Made this page show characters and which ones are in use.


"gags" Page

Added this page. It lists all the current gags (the outside ones or the ones for the current interior) and whether or not they're loading/loaded. It also shows their joint positions in the world.



Added a "world spheres" Page that shows information about any currently loaded World Spheres and their respective Lens Flares (if applicable).

Added "Parked cars enabled" to show if parked cars are currently enabled.

"mission" Page

  • Made this page show "null" for null objectives instead of crashing.
    • This is helpful for debugging in the event the stage's objective is not getting added.

"traffic" Page

Made this page render the segments of the road the car is currently on (and the previous roads segments if the car is on an intersection).

"triggers" Page

  • Made this page include the type number of locators in brackets after the type name.
