Input

Photo mode uses Enhanced Input throughout. While it is open, it adds its mapping context with priority 1000 and an input component that blocks your game’s own bindings, so its keys never trigger game actions. Every action has Trigger when Paused on, so photo mode works while the game is paused.

The built-in layout

With the profile’s Input Config empty, photo mode builds its default layout in code. See Controls for the keys.

Changing the keys

1. Copy the /TALensman/Input folder into your project, or create the assets from an Editor Utility or Python:

   import unreal
   unreal.TALensmanInputConfig.create_default_assets("/Game/Input/Lensman")

   This creates DA_Lensman_Input, IMC_Lensman and the 17 input actions. It does nothing if the assets already exist.

2. Change the keys in IMC_Lensman.

3. Set DA_Lensman_Input as the profile’s Input Config.

The button prompts read the keys from the mapping context, so they always match your changes.

The input actions

Action	Type	Does
IA_Lensman_Move	Axis 2D	Move the camera; move a sticker.
IA_Lensman_Elevate	Axis 1D	Up and down; resize a sticker.
IA_Lensman_LookStick	Axis 2D	Look with the gamepad; turn a sticker.
IA_Lensman_LookMouse	Axis 2D	Look with the mouse, while the right button is held.
IA_Lensman_Zoom	Axis 1D	Zoom with the wheel.
IA_Lensman_Fast	Bool, held	Faster camera.
IA_Lensman_ResetCamera	Pressed	Reset the camera.
IA_Lensman_FocusCenter	Pressed	Lock focus on the centre of the picture.
IA_Lensman_SwitchTab	Axis 1D	Previous (−) and next (+) tab.
IA_Lensman_NavigateRows	Axis 1D	Previous and next row.
IA_Lensman_Adjust	Axis 1D	Change the selected row.
IA_Lensman_Activate	Pressed	Press a button row, step a choice, apply a tile; play and pause a clip in the gallery.
IA_Lensman_Capture	Pressed	Take a photo or record a clip (the Clip tab’s Capture button); stop recording and keep the clip.
IA_Lensman_ToggleUI	Pressed	Hide and show the menu.
IA_Lensman_Gallery	Pressed	Open the gallery.
IA_Lensman_Back	Pressed	Back, exit; cancel a clip while recording.
IA_Lensman_Delete	Pressed	Delete a photo or clip in the gallery.

The data asset DA_Lensman_Input (TALensman Input Config) holds the mapping context, its Priority (1000) and one property per action.

The open key is separate: it comes from the project settings (Add Open Key, Open Keys). See Opening photo mode.

Held keys

Rows and values repeat while a key or D-pad direction is held. Photo mode does this itself: one step on press, then a repeat after a short delay.

Action	First repeat after	Then every
NavigateRows	0.4 s	0.12 s
Adjust	0.35 s	0.06 s

When you change the keys, leave Navigate Rows and Adjust without triggers; photo mode repeats them itself while the key is held.

Note

One key can serve two actions on different pages: X on a gamepad hides the menu on the photo mode screen and deletes a photo in the gallery. While the share code or rename box is open, it takes the keyboard and gamepad, so typing never reaches these actions.
