Kit input

126 herramientas. Generado a partir del código fuente del plugin; no lo edites a mano.

Las descripciones de las herramientas y de los argumentos se muestran en inglés porque reflejan el schema de las herramientas (el mismo texto que el agente recibe en tools/list).

Guía

Authoring and testing input for a project: Enhanced Input assets (Input Actions, Input Mapping Contexts, key mappings with modifiers and triggers), Player Mappable Key Settings and user settings, Project Settings > Input (classic mappings, axis config, console keys, mouse/viewport options), Enhanced Input developer settings, PIE-time injection and queries, and Blueprint wiring.

Works on UE 4.27 through 5.8. Tools marked with a minimum engine version are hidden on older engines. The kit is split over four classes (UUeaKit_Input, UUeaKit_InputAssets, UUeaKit_InputSettings, UUeaKit_InputRuntime) that all expose the input. namespace.

input.list_blueprint_input_events	Enhanced action, classic action/axis and key event nodes (+ AddMappingContext calls) in the event graphs.
input.add_enhanced_action_event / input.add_legacy_action_event / input.add_legacy_axis_event / input.add_key_event	Event nodes; existing identical nodes are returned instead of duplicated.
input.remove_input_event	Remove an input event node by GUID.

Recipe: complete Enhanced Input setup in five calls

1. input.create_standard_set {folder:"/Game/Input"} -> IA_* actions + IMC_Default with keyboard/mouse/gamepad.
2. input.set_default_input_classes {playerInputClass:"EnhancedPlayerInput", inputComponentClass:"EnhancedInputComponent"} (5.1+ projects already default to these).
3. input.add_context_to_blueprint_begin_play {blueprint:"BP_PlayerCharacter", context:"IMC_Default", priority:0}.
4. input.add_enhanced_action_event {blueprint:"BP_PlayerCharacter", action:"IA_Jump"} then connect the Triggered pin with bp.connect_pins (repeat for IA_Move etc.).
5. input.validate_context {context:"IMC_Default"} then asset.save_all.

Recipe: hand-built context with a declarative spec

input.build_context_from_spec {
  "name": "IMC_Vehicle", "folder": "/Game/Input",
  "mappings": [
    {"action": "IA_Throttle", "valueType": "axis1d", "key": "W"},
    {"action": "IA_Throttle", "key": "S", "modifiers": [{"className": "Negate"}]},
    {"action": "IA_Throttle", "key": "Gamepad_RightTriggerAxis"},
    {"action": "IA_Handbrake", "key": "SpaceBar", "triggers": [{"className": "Hold", "properties": [{"key": "HoldTimeThreshold", "value": "0.3"}]}]}
  ]
}

Recipe: test without touching the keyboard (PIE)

1. Start PIE (edit kit), input.pie_status.
2. input.pie_list_applied_contexts - if empty, input.pie_add_context {context:"IMC_Default"} for this session.
3. input.pie_inject_action {action:"IA_Jump", value:{x:1}} or input.pie_inject_key {key:"SpaceBar", event:"tap"}.
4. input.pie_get_action_value {action:"IA_Move"} while input.pie_inject_axis {key:"Gamepad_LeftX", delta:1}.

Recipe: player key rebinding (5.3+)

1. input.set_action_mappable_settings {action:"IA_Jump", name:"Jump", displayName:"Jump", displayCategory:"Movement"}.
2. input.set_enhanced_developer_settings {properties:[{key:"bEnableUserSettings", value:"true"}]} and input.add_default_mapping_context {context:"IMC_Default", registerWithUserSettings:true}.
3. In PIE: input.pie_list_player_key_mappings, input.pie_map_player_key {mappingName:"Jump", newKey:"F", slot:"First"}, input.pie_save_user_settings.

Recipe: classic input (4.27 projects without Enhanced Input in the pawn)

1. input.add_axis_mapping {name:"MoveForward", key:"W", scale:1} and {key:"S", scale:-1}
2. input.add_action_mapping {name:"Jump", key:"SpaceBar"}
3. input.add_legacy_axis_event {blueprint:"BP_Pawn", name:"MoveForward"} / input.add_legacy_action_event {..., name:"Jump"}.
4. Later: input.migrate_legacy_to_enhanced {removeLegacy:false} to convert.

Gotchas

• Key names are FKey names, not labels: SpaceBar, LeftMouseButton, Mouse2D, MouseX, Gamepad_LeftX, Gamepad_Left2D, Gamepad_FaceButton_Bottom. Matching is case-insensitive and display names work too (input.find_key shows suggestions).
• A 2D action mapped to a 1D key needs Swizzle to drive Y; Negate inverts. Property values use engine text form (true, 0.5, (X=1,Y=0,Z=0), enum names like YXZ, Radial).
• Typed add tools with key empty target the Input Action asset (applies to all mappings); with context + key they target one mapping. set_*_properties / reorder_* work the same way.
• add_mapping refuses a duplicate Action+Key; edit_context / build_context_from_spec skip duplicates instead. Indices come from get_context and shift after a removal.
• set_action_properties, set_viewport_input_settings, set_axis_config use text tri-states for booleans ("false"); empty means "leave unchanged".
• add_context_to_blueprint_begin_play uses a literal asset reference unless variableName is given; it splices before whatever BeginPlay already executed and returns the created nodes.
• pie_* tools need a running PIE session and affect the live player only (nothing is saved); injected action values last one frame. Legacy key injection goes through the PlayerController so both classic and Enhanced mappings react.
• press_editor_key targets the editor's focused Slate widget (not the game viewport).
• Combo triggers are deprecated by Epic in 5.8 but still work; add_combo sets the steps through reflection so the property names of every 5.x version are handled.
• remove_all_legacy_mappings, delete_asset, clear_mappings and remove_input_event are destructive; asset edits are undoable with edit.undo, settings writes go straight to the .ini.
• New assets are dirty in memory until asset.save / asset.save_all.
