Debug mode

Debug mode is a special feature that makes it easier for developers/contributors to test out game features without needing to play a new game from scratch. After setting "debug: true" in the Options File, you can enable it by pressing Ctrl-D in-game to access a variety of features:

Geoscape: Unlocks all research and shows globe country and region borders. Clicking on the globe returns the point coordinates. This option can be toggled, and toggles between showing country borders, regional borders, and mission zones.

Battlescape: Whole map is revealed and opening the inventory screen resets TUs. Clicking the map returns the point coordinates. With traceAI enabled in the config, AI behavior is revealed and logged. Please note, in debug mode QuickSave/QuickLoad feature in Battlescape are completely disabled.

Ctrl-V will reset visibility on all tiles, useful for observing LOS behaviour.

Ctrl-K will kill all live aliens in the mission (nothing will be recovered).

Ctrl-J will stun all live aliens in the mission (useful for testing recovery).

Ctrl-W will warp the selected unit to the mouse cursor's current position.

F8 will cycle through various engine processing speeds, useful for debugging animation errors.

You can also press Ctrl-U or set "debugUi: true" to reveal the borders of the interface text, to debug translation errors.

If the Commendations Mod is being played, Ctrl-C will wipe all earned commendations while retaining statistics, useful for debugging how they're awarded.
