Small Debug Window Mod for KSP 2

KSP2 ships with many debug widgets, and a fully functional Lua interface. There is even a keybind for toggling the debug menu (CTRL+F8), but unfortunately for us, it appears that the actual .lua scripts that create the window (_Dev\Tools\DebugScripts\index.lua) are not shipped with the game. Additionally, the game's lua execution functions are patched out.

This mod provides the following:

• A functional debug window that provides some of the functionality that the KSP2 built-in debug menu would've included, wired up to the in-game debug window keybind (CTRL+F8)
• Patches the game's .lua file execution so that you can actually execute your own .lua debug scripts

Features

Scripting

• Lua Debug Panel
  • This is a KSP2 built-in debug panel which can be used to execute .lua files with arguments. Quite useful for quickly running Lua mods or debug scripts.

Debug

  • Accessible also via the settings currently
• Toggle Localization Debug
  • Creating a mod and want to modify the texts shown in the UI, or to re-use the same messages? Enable this and the in-game texts show the names of the localized messages instead!
• Dump VAB parts list into a CSV file
  • Dump the full parts list from the VAB into a CSV in the game's folder
• Spawn a new Kerbal at camera position
  • Have you always wanted to test the thermal properties of a Kerbal, but don't want to sacrifice your own Kerbals? Use this to spawn a new one on the camera's position.
• Toggle VAB size limit boxes
  • Building an absolutely gigantic ship and need to know exactly where the VAB's limits are? Check this.
• Toggle notification visibility
  • Annoyed by warnings about your ship bursting into flames? Use this.

Rendering and VFX

FX debug tools

This is a KSP2 built-in debug widget.

Want to damage parts or joints, or destroy them completely to see how your ship will perform if you run into a rapid unscheduled disassembly event? Try it out.

This widget also shows a console that shows debug messages related to VFX. Useful for mod authors.

Quick actions

The following spawn a preset ship/plane for testing:

• Generate a ship in VAB
• Generate a ship on the launchpad
• Generate a ship in Kerbin orbit
• Generate a plane in VAB
• Generate a plane on the runway

The following take your current ship to a VAB or BAE (it is uncertain what a BAE is, possibly an upcoming base builder?):

• Go to VAB on Kerbin
• Go to VAB in Kerbin orbit
• Go to BAE on Kerbin
• Go to BAE in Kerbin orbit

Installation

1. Download and install the BepInEx 5 for KSP 2 mod loader (tested with 5.4.21)
2. Download this mod's .zip file
3. Extract it into the KSP2 directory (e.g. steamapps\common\Kerbal Space Program 2)
4. Start KSP2 and press CTRL+F8

Customizing

This mod drops a custom debug menu .lua script into KSP2_x64_Data\_Dev\Tools\DebugScripts\index.lua, which is where the built-in debug menu functionality looks for its main script.

It is easy to customize; just edit it with a text editor (or an IDE). It leverages KSP2's built-in Lua global interop functions.

A list of known Lua globals is included in the README.md file in the same directory. You may need to peek at the KSP2 assembly with DotPeek to see what the arguments are.

Troubleshooting

If no menu appears, enable the BepInEx console and see if there are any errors. If there are problems, please raise an issue on this mod's GitHub repository.
