Kit edit

260 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

Editor essentials every other kit assumes: server info and undo/redo, reflection over any object, Play-In-Editor control with input injection, the level viewport and selection, console variables and rendering, log capture, ini/settings classes, plugins and the project descriptor. The kit is split over nine classes (UUeaKit_Edit, _EditCheckpoint, _EditObject, _EditPlay, _EditView, _EditConsole, _EditConfig, _EditTools, _EditWorkflow) that all register as kit edit; the tools are spread over eleven prefixes. Content-browser asset tools (asset.* / import.*) live in the asset kit (see Docs/guides/asset.md); the only asset. tool of this kit is asset.preview.

log.	12	editor log read, categories/verbosity, in-memory capture with markers, log file markers
settings.	21	settings.get/set, raw ini files (get/set/search/diff/flush), settings classes (schema, get_many/set_many, save/reload/reset)
project.	22	project info/paths/descriptor/version, default maps and game mode classes, modules/targets/maps/platforms, capabilities, text files, header search
plugin.	13	list/find/info, enable/disable, dependencies/dependents, content plugins, modules, .uplugin descriptor edits

276 tools in total on UE 5.x (272 on 4.27). Every tool takes JSON arguments named after the C++ struct fields in camelCase without the b prefix (bRecursive -> recursive). Asset references accept an object path (/Game/Folder/Asset.Asset), a package path (/Game/Folder/Asset) or a unique bare name.

Start here

1. edit.ping -> engine version, project and tool count. edit.get_state -> PIE, active transaction, dirty packages, selection, builds, focus.
2. project.info / project.get_capabilities -> current map, default game mode/maps, plugins, Nanite/Lumen/ray tracing availability, kits and tool count.
3. edit.search_tools {query:"screenshot viewport"} finds tools by words in name + description; edit.get_tool_schema {tool:"asset.rename_many"} gives the full input/output JSON schema; edit.get_tool_counts shows counts per prefix/kit and how many tools are hidden on this engine.

Recipe: inspect and edit any object property

1. object.resolve {object:"cdo:/Game/BP/BP_Enemy"} (or actor:Enemy_3, settings:RendererSettings, /Game/Data/DT_Items.DT_Items) to confirm what you are pointing at.
2. object.list_properties {object:"cdo:BP_Enemy", editableOnly:true, contains:"Health"} for exact names and types; object.get_property_metadata {class:"BP_Enemy", property:"MaxHealth"} for ClampMin/ClampMax.
3. object.set_property {object:"cdo:BP_Enemy", property:"MaxHealth", value:"250"} or several with object.set_properties {values:[{key:"MaxHealth", value:"250"}, {key:"Mesh.RelativeScale3D", value:"(X=2,Y=2,Z=2)"}]}.
4. object.diff_from_default {object:"cdo:BP_Enemy"} shows every override; asset.save {asset:"BP_Enemy"} writes the Blueprint. For a settings CDO finish with settings.save {section:"RendererSettings"} instead.

Recipe: batch calls in one round trip

edit.call_many {
  "calls": [
    {"tool": "edit.begin_transaction", "argsJson": "{\"title\":\"Rename actor\"}"},
    {"tool": "object.set_property", "argsJson": "{\"object\":\"actor:Door_1\",\"property\":\"IsOpen\",\"value\":\"True\"}"},
    {"tool": "edit.end_transaction", "argsJson": "{}"}
  ],
  "stopOnError": true
}

argsJson is a JSON object string; each result carries ok, resultJson and milliseconds. Wrap the batch in edit.begin_transaction {title:"..."} ... edit.end_transaction when the user should be able to undo it in one step. See Docs/guides/asset.md for an asset-import batch.

Recipe: checkpoint, try, roll back

1. edit.checkpoint_create {name:"before-lighting", withPreview:true} (fails if the name exists; replace:true overwrites). It records the undo position, dirty packages and a 256 px capture.
2. Do the work with any tools. Each mutating reply carries undoable (false for tools that write files, save/delete packages on disk or write config: those are NonUndoable).
3. edit.checkpoint_diff {name:"before-lighting"} lists the transactions, newly dirty packages and mutating calls since; view.capture_compare {checkpoint:"before-lighting"} returns the before/after images and changedPixelRatio.
4. Keep it (edit.checkpoint_delete) or undo it all: edit.checkpoint_rollback {name:"before-lighting", dryRun:true} first, then without dryRun. Read rollback.issues: saved_to_disk (the file keeps the saved content), missing_on_disk, non_undoable_call, history_reset (a map load or asset deletion cleared the undo buffer), inside_active_transaction.

For a single batch use edit.call_many {atomic:true, calls:[...]}: the first failed call rolls every earlier call back (rolledBack, rollback). Atomic batches, workflows and rollbacks refuse to run while edit.begin_transaction (or any editor transaction) is open. Atomic batches and atomic workflows also refuse up front (nothing runs) when a call or main step is a NonUndoable tool (saves, asset deletes, file writes); run those separately or with atomic:false. A checkpoint rollback with a non_undoable_call issue never reports complete:true.

Recipe: see what a call did (_preview)

Add "_preview" to the arguments of any tool; it is not part of any schema and is stripped before the tool runs.

• actor.spawn_mesh {mesh:"/Engine/BasicShapes/Cube", name:"Crate_1", _preview:"viewport"} -> the reply gets an image of the level viewport framed on the changed actors (or the selection) plus preview {kind, subject, width, height}; the camera is restored afterwards.
• material.set_settings {..., _preview:"asset"} -> the thumbnail of the first changed asset.
• _preview:"auto" picks asset for asset changes and viewport for level changes.
• On failure you get previewError (no viewport in unattended/-nullrhi runs, asset without a thumbnail renderer) and the tool result is unchanged. During PIE the play viewport is captured.
• Direct captures: view.screenshot {width:640, height:360, frameActors:["Crate_1"], showFlags:{"Grid":false}, format:"jpg"} and asset.preview {asset:"/Game/Materials/M_Rock", size:256}.

Recipe: run a workflow

1. edit.list_workflows (or MCP prompts/list) -> ids, arguments with defaults, availability on this engine. edit.get_workflow {id} shows the JSON and the exact step list as prompt text.
2. edit.validate_workflow {id:"actor.blockout_basic", arguments:{prefix:"Block"}} checks tools, argument names against schemas, plugins/min engine and ${...} substitutions.
3. edit.run_workflow {id:"actor.blockout_basic", arguments:{prefix:"Block"}, dryRun:true} lists the resolved steps; run it without dryRun (and with _preview:"viewport" for a final image). Atomic by default: a failed step rolls everything back; the checkpoint workflow:<id> stays so edit.checkpoint_rollback {name:"workflow:actor.blockout_basic"} can undo a successful run later.
4. runCleanup:true runs the workflow's cleanup steps (they may delete assets on disk).

Workflow files: {id, title, description, category, minEngine, requiresPlugins[], arguments[{name, type, description, default}], steps[{id, tool, args, expect?, optional?}], verify[{tool, args, expect}], cleanup[...]}. ${arg} and ${stepId.field.path} are substituted (a string that is only one token keeps the value's JSON type); expect maps reply paths to values ("*" = present and not empty). Put your own in <Project>/Saved/UEAMCP/Workflows/*.json (same id overrides a shipped one).

Recipe: PIE test loop with input injection, screenshots and log markers

1. asset.save_all, edit.set_background_throttling {enabled:false}, log.start_capture.
2. play.start {map:"/Game/Maps/Arena", mode:"viewport"} then play.status until running:true (the session starts on the next tick); play.advance_frames {frames:30} lets BeginPlay settle.
3. log.write {message:"STEP jump"} and mark = log.get_marker before each step, then drive the player: play.tap_key {key:"SpaceBar", holdFrames:5}, play.set_axis {key:"Gamepad_LeftY", value:1, frames:60}, play.mouse_delta {deltaX:200, frames:10}, or play.call_function {actor:"BP_Player_C_0", function:"Fire"}.
4. Observe: play.get_player_state (velocity, movement mode, falling), play.get_actor {actor:"Door_1", property:"IsOpen"}, play.line_trace, play.get_visible_widgets {textOnly:true}, play.screenshot.
5. log.read_capture {sinceIndex:mark, minVerbosity:"Warning"} for errors since the marker (regex for patterns); play.get_stats for frame time and boundBy.
6. play.stop, then log.stop_capture. Stop PIE before editing Blueprints again.

play.press_key keeps the key down until play.release_key; play.set_axis / mouse_delta tick one frame per step. Enhanced Input actions can also be driven with input.pie_inject_action.

Recipe: config and scalability change

• Quick cvar: console.set_cvar {name:"r.ScreenPercentage", value:"75"} (runtime only) or console.set_many {variables:[{key:"r.Shadow.MaxResolution", value:"4096"}], persist:true} to write [ConsoleVariables] in DefaultEngine.ini.
• Quality: render.set_scalability {group:"Shadow", level:"epic"} or {group:"all", level:2, persist:true}; render.set_anti_aliasing {method:"tsr"}, render.set_lumen {globalIllumination:true, reflections:true} (5.0+).
• Project setting: settings.get_class_schema {section:"RendererSettings", category:"Lumen"} to find the exact property, then settings.set {section:"RendererSettings", property:"bSupportSkyAtmosphere", value:"True"} or settings.set_many. settings.diff_from_default {file:"Engine"} shows every project override afterwards.
• Raw ini: settings.search_ini {query:"MaxFPS"} -> settings.set_ini {file:"Engine", section:"/Script/Engine.RendererSettings", key:"...", value:"..."}.
• Game defaults: project.set_default_maps {gameDefaultMap:"/Game/Maps/Arena", globalDefaultGameMode:"/Game/Core/BP_GameMode.BP_GameMode_C"}.

Recipe: enable a plugin

1. plugin.find {plugin:"Niagara"} -> exact name and whether it is already enabled; plugin.get_dependencies {plugin:"MyPlugin", recursive:true} lists prerequisites with found / active flags.
2. plugin.set_enabled {plugin:"MyPlugin", enabled:true} writes the .uproject; the reply says restartRequired:true. Modules load only after the editor restarts, so tell the user to restart before using content or classes from the plugin (plugin.list_modules shows loaded:false until then).
3. After the restart: project.get_capabilities / plugin.list_content_plugins to confirm the mount point.

Recipe: run automation tests

1. edit.list_tests {contains:"Project.Functional", filter:"product"} -> full test paths.
2. edit.run_test {test:"Project.Functional.Doors.OpenClose", maxFrames:3000} runs synchronously, pumping latent commands, and returns pass/fail, duration, frames used and every event with file/line.
3. edit.run_tests {test:"Project.Functional", maxTests:20, stopOnFailure:true} for a suite; edit.get_test_results re-reads the last run. Pair with log.get_marker / log.read_capture to collect warnings emitted during the run.

Recipe: level and lighting

1. edit.load_map {map:"/Game/Maps/Arena", saveCurrent:true}; edit.get_map_info for actor counts, streaming levels, bounds and unbuiltLightingObjects.
2. edit.set_world_settings {values:[{key:"DefaultGameMode", value:"BP_GameMode"}, {key:"KillZ", value:"-5000"}]}.
3. edit.build {type:"lighting", quality:"preview"} and poll edit.is_building; edit.get_lighting_info afterwards.
4. edit.map_check for actor errors; view.focus_actors {actors:["BadActor_1"]} + view.screenshot to show them.
5. edit.save_map {saveAll:true}.

Gotchas

• Everything runs on the editor game thread, synchronously: long tools (edit.build, edit.run_tests, play.advance_frames with many frames, edit.live_coding_compile, deep asset.get_dependencies walks, project.search_headers) block the editor until they return. Keep frames, maxDepth, maxFrames and limit reasonable; edit.build returns as soon as the build has started, so poll edit.is_building.
• Tools marked Mutates in the schema run inside an editor transaction and are undoable with edit.undo; edit.begin_transaction groups several into one step and edit.cancel_transaction reverts them. Not transactional: settings.*, console.set_* with persist, plugin.*, project.write_file / set_* (they write ini, .uproject or .uplugin files directly), play.* runtime state, source control (asset.checkout/revert, edit.sc_*) and file imports on disk.
• Destructive tools: asset.delete, asset.delete_many (force:true nulls references), asset.delete_folder, asset.consolidate, asset.revert, edit.sc_revert, edit.reset_undo_buffer (cannot be undone), settings.remove_ini_key, settings.reset_to_defaults, project.delete_file. asset.delete refuses while referencers exist; check asset.get_referencers first.
• MinEngine-gated tools are hidden on older engines: render.set_lumen, render.set_nanite, render.set_gi_method, render.set_reflection_method need UE 5.0+. edit.get_tool_schema reports availableOnThisEngine; render.get_scalability returns -1 for groups the engine lacks (GlobalIllumination, Reflection, Landscape on 4.27). view.set_camera_speed.scalar is ignored on 5.7+.
• Nothing is auto-saved: asset.save / asset.save_many / asset.save_all (or save:true on the create/import tools) write to disk. asset.save_all before play.start so PIE sees the latest compiled state. settings.set / set_many / set_ini save immediately; object.set_property on a settings:<Class> object needs settings.save.
• play.* actor tools fall back to the editor world when PIE is not running; input injection, teleport, spawn, possess, stats and widgets need a running session and affect only the live world. play.start returns before the world exists: poll play.status. Stop PIE before editing Blueprints.
• Actor references (every kit): the exact label or object name of exactly one actor, or class:<ClassName> for the only actor of a class (class:WorldSettings). Prefixes and "first match" are not accepted; ambiguous references answer E_NOT_FOUND.
• Checkpoints live in memory for the editor session only. Loading a map, deleting assets or edit.reset_undo_buffer clears the undo buffer: older checkpoints then report history_reset.
• view.* needs a level viewport; screenshots need the editor visible and, on some drivers, in the foreground. view.screenshot_from restores the camera afterwards; view.set_realtime is required for Niagara/animation previews to advance.
• console.set_cvar uses SetByConsole priority, which overrides scalability and project settings until restart; console.get_cvar.setBy tells you which layer currently owns a value. console.exec captures output; play.exec_console does not.
• plugin.set_enabled and render.set_ray_tracing only take effect after an editor restart. project.write_file / delete_file / rename_file refuse .uasset/.umap files and paths outside the project; project.read_file also reads inside the engine directory.
• object.set_property values follow ImportText: booleans True/False, enums by name, structs (X=1,Y=2,Z=3), arrays (a,b,c), object references as full paths. Writing to a CDO changes the class defaults for every instance; writing to actor:<Label> during PIE is lost when PIE stops.
• asset.rename_many and asset.find_unused can touch hundreds of assets: use dryRun:true and a folder filter first. Bulk tools (*_many, asset.validate, settings.set_many, object.set_properties) report per-item failed entries instead of aborting.
• Source control tools do nothing useful when edit.sc_info reports enabled:false; Live Coding tools are Windows only and report available:false elsewhere.
