Kit level

193 ferramentas. Gerado a partir do código-fonte do plugin; não edite manualmente.

As descrições das ferramentas e dos argumentos são exibidas em inglês porque espelham o schema das ferramentas (o mesmo texto que o agente recebe em tools/list).

Guia

Everything about the world the agent is building: maps and sublevels, editor layers, World Settings, environment actors (sun, sky light, sky atmosphere, fog, clouds, reflection captures), post-process volumes and settings, splines and spline meshes, gameplay/utility volumes, lighting builds and Lightmass, navigation, and (UE 5) World Partition, data layers and level instances.

Works on UE 4.27 through 5.8 (175 tools on 4.27, 192 on 5.8). Tools marked with a minimum engine version are hidden on older engines. The kit is split over eight classes (UUeaKit_Level, UUeaKit_LevelEnvironment, UUeaKit_LevelPostProcess, UUeaKit_LevelSplines, UUeaKit_LevelVolumes, UUeaKit_LevelLighting, UUeaKit_LevelNav, UUeaKit_LevelPartition) that all expose the level. namespace.

Generic actor work (spawn, transform, properties, selection, folders, groups) lives in the actor kit; asset CRUD in asset; PIE and undo in edit.

Start here

1. level.get_current — name, package, dirty/untitled state, actor and sublevel counts, whether the level is partitioned, unbuilt lighting and world bounds.
2. level.list_environment — which of sun / sky light / sky atmosphere / fog / clouds / reflection captures already exist.
3. level.setup_default_environment — creates the missing ones in one call.
4. level.get_stats — actors by class, lights, meshes, brushes, volumes, estimated triangles.

Recipe: a lit, playable level in three calls

1. level.setup_default_environment {sun:true, skyLight:true, skyAtmosphere:true, fog:true, sunPitch:-45}
2. level.add_post_process_volume {name:"PP_Global", unbound:true}
3. level.set_exposure {target:"PP_Global", method:"manual", bias:1} — without this the auto exposure of a new level makes everything look flat.

Then level.save {saveAs:"/Game/Maps/MyLevel"} (a brand new level is untitled until saved).

Recipe: sunset mood

1. level.apply_environment_preset {preset:"sunset", keepExisting:true}
2. level.set_fog {density:"0.08", volumetric:"true"}
3. level.set_sun_from_time {hour:18.5, latitude:40} for a precise time of day.
4. level.set_color_grading {target:"PP_Global", temperature:"7500", saturation:"(X=1.1,Y=1.05,Z=1,W=1)"}

Recipe: a post-process look

1. level.set_bloom {target:"PP_Global", intensity:"0.8", threshold:"-1"}
2. level.set_ambient_occlusion {target:"PP_Global", intensity:"0.6", radius:"80"}
3. level.set_vignette {target:"PP_Global", intensity:"0.4"}
4. level.get_post_process {target:"PP_Global", onlyOverridden:true} to review what you changed.
5. level.copy_post_process {from:"PP_Global", to:"PP_Interior"} to reuse it.

Recipe: a spline road with meshes

1. level.add_spline {name:"Road", points:[{x:0,y:0,z:0},{x:2000,y:0,z:0},{x:4000,y:1500,z:0}]}
2. level.set_spline_point_type {actor:"Road", type:"curve", index:-1}
3. level.add_spline_mesh_segments {actor:"Road", staticMesh:"/Game/Meshes/SM_RoadSegment", forwardAxis:"x"}
4. level.place_along_spline {actor:"Road", staticMesh:"/Game/Meshes/SM_Lamp", spacing:800, alignToTangent:true, offset:{x:0,y:250,z:0}}
5. level.sample_spline_evenly {actor:"Road", count:20} if you need the waypoints for something else.

Recipe: trigger, nav bounds and a build

1. level.add_volume {kind:"trigger_box", name:"TB_Door", location:{x:0,y:0,z:100}, extent:{x:200,y:200,z:150}}
2. level.set_trigger_collision {actor:"TB_Door", profile:"Trigger", generateOverlapEvents:"true"}
3. level.add_nav_mesh_bounds {extent:{x:5000,y:5000,z:1000}}
4. level.build_navigation {wait:true} then level.get_navigation_status.
5. level.find_path {start:{x:0,y:0,z:0}, end:{x:3000,y:0,z:0}} to verify the navmesh connects.

Recipe: sublevel workflow

1. level.save first — a persistent level must exist on disk before it can own sublevels.
2. level.create_sublevel {folder:"/Game/Maps", name:"L_Props", streamingClass:"blueprint"}
3. level.set_current_sublevel {sublevel:"L_Props"} so new actors land there.
4. level.move_actors_to_sublevel {actors:["SM_Crate1","SM_Crate2"], sublevel:"L_Props"}
5. level.add_streaming_volume {sublevels:["L_Props"], extent:{x:3000,y:3000,z:1000}}
6. level.set_sublevel_visible / level.set_sublevel_loaded while editing; level.list_sublevels to check the state.

Recipe: data layers (UE 5.1+, partitioned levels)

1. level.is_partitioned — everything else in this section returns E_NOT_SUPPORTED when false.
2. level.create_data_layer {name:"DL_Vegetation", folder:"/Game/DataLayers", runtime:true}
3. level.add_actors_to_data_layer {actors:["SM_Tree1","SM_Tree2"], dataLayer:"DL_Vegetation"}
4. level.set_data_layer_state {dataLayer:"DL_Vegetation", state:"activated", visible:"true"}
5. level.set_actor_spatial {actor:"BP_QuestGiver", spatiallyLoaded:false} for actors that must always be loaded.

Gotchas

• Untitled levels. A newly created level lives in /Temp/ until saved. level.add_sublevel, level.create_sublevel and level.save (without saveAs) all need a real package on disk — save the persistent level first.
• Use the level.* map tools for maps, not the asset kit. level.duplicate_map, level.rename_map and level.delete_map go through world-aware engine APIs. The generic asset tools are built on UEditorAssetLibrary, which refuses anything "of type Map/Level" outright on 4.27. When one of these does fail, the reply now carries the engine's own error text.
• Volumes are brushes. Most volume kinds are BSP brush actors: changing extent rebuilds the brush (level.set_volume_extent), it is not a scale. trigger_sphere and trigger_capsule are shape components instead and use radius. level.list_volume_kinds tells you which is which.
• Unbound post-process volumes. level.add_post_process_volume defaults to unbound:true, which ignores the volume's bounds and affects the whole level — that is almost always what you want for a global look. Set unbound:false for a local zone.
• Override flags. Reading a post-process field always returns a value; only overridden:true means the target actually applies it. level.get_post_process with onlyOverridden:true shows what you changed.
• Optional setter fields are text. level.set_light, level.set_fog, level.set_bloom and friends take strings so an empty value means "leave unchanged" ("0" and "false" are real values). Colours are separate: pass color plus useColor:true.
• Unknown fields are reported, not fatal. Fields that do not exist on the running engine (filmGrain* on 4.27, depthOfField.method on 5.x, bloomConvolutionScatterDispersion on 4.27) come back in failed with a reason instead of failing the whole call.
• Invalid build-data GUIDs crash the engine, not just the tool. UMapBuildDataRegistry does check(Guid.IsValid()), so a sky atmosphere, reflection capture or light component carrying a zero GUID asserts the editor the moment a build touches it — and a component spawned by script can end up that way. Every build tool in this kit (build_lighting, build_geometry, build_all, build_reflection_captures, recapture_reflections) repairs them first and reports what it fixed in repaired[]. level.repair_build_data_ids runs the same pass on its own if you want to check or fix a level before handing it to another tool.
• Lighting builds are slow. level.build_lighting returns immediately unless you pass wait:true; poll level.get_build_status otherwise. It is not undoable.
• Unbuilt lighting. Adding or moving a static/stationary light marks the level's lighting out of date (level.get_current reports lightingUnbuilt). Use movable lights, or level.set_force_no_precomputed_lighting {enabled:true}, to skip baking entirely.
• Navigation needs bounds. There is no navmesh until a nav_mesh_bounds volume exists; level.find_path and level.project_point_to_nav return "not found" until then. maxSlope is a Recast generation setting, not an agent property — set it with level.set_recast_settings {properties:[{key:"AgentMaxSlope", value:"44"}]}.
• Partition tools are 5.x only and return a clean E_NOT_SUPPORTED on a non-partitioned world rather than failing hard. level.is_partitioned works on every version.
• level.load_region holds the region for the session. The loader adapter must stay alive or the cells unload again immediately, so the kit keeps it until level.unload_region releases it. level.unload_region therefore only releases regions this session loaded; it reports that clearly when a box matches nothing.
• Transactions. Every Mutates tool is wrapped in an editor transaction, so edit.undo works. Builds, level.save, level.delete_map and level.set_nav_agent (which writes DefaultEngine.ini) are not undoable.
• Actor references accept an actor label, an object name or a unique class name ("Sun", "DirectionalLight_1", "PointLight"), matched in that order, then by unique prefix.
• New and edited level actors are dirty in memory until level.save / asset.save_all.
