Add invert L1/R1 and L2/R2 in setting - #13
Conversation
📝 WalkthroughWalkthroughThe change adds persisted default and swapped shoulder-trigger layouts. Settings modals dispatch layout changes, the application saves them, and ChangesShoulder-trigger layout mapping
Estimated code review effort: 3 (Moderate) | ~20 minutes Mergeability Score: 🟡 Moderate · up to The swap setting is close to merge-ready, but physical shoulder presses can currently produce only partial virtual trigger input, which may break games that depend on full L2/R2 activation. Fix that bounded input-mapping issue before merging; the diagram label and Spanish accent are minor follow-ups. Possibly related PRs

Update the rear-touch diagram for Swapped.
This selector can map the rear panel to virtual L1/R1. The diagram above still labels its zones as L2/R2. Read shoulder_trigger_layout() when rendering the diagram and show L1/R1 for Swapped.

Correct the Spanish heading.
Replace Asignacion with Asignación.

Send full trigger pressure for physical shoulder buttons.
When Swapped is selected, TriggerIntensity limits physical L1/R1 to the rear-panel pressure value. A physical shoulder button can then send only a partial L2/R2 press.
Use u8::MAX when l1_held or r1_held is true.
Proposed fix
- trigger(axis(Axis::TriggerLeft)).max(if l1_held { rear_touch.pressure() } else { 0 }),
- trigger(axis(Axis::TriggerRight)).max(if r1_held { rear_touch.pressure() } else { 0 }),
+ trigger(axis(Axis::TriggerLeft)).max(if l1_held { u8::MAX } else { 0 }),
+ trigger(axis(Axis::TriggerRight)).max(if r1_held { u8::MAX } else { 0 }),📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Do you have any screenshots of your implementation? @Shiroe835 |

@Shiroe835 I don’t have a problem if it was made with AI. If it works, has been tested, and passes the checks/tests, then it’s OK for me. |

Add a button to invert the position of L1/R1 and L2/R2.
Summary
Adds a setting to dynamically swap physical L1/R1 shoulder buttons with virtual L2/R2 triggers during streaming sessions.
Because the PS Vita lacks dedicated physical L2/R2 triggers, many GFN streams rely on the rear touchpad or front touchscreen by default. This feature allows players to map primary actions (e.g., aiming and shooting) to physical shoulder buttons.
