Guide

Use physics for project physics policy, physical-material assets, and collision queries during Play-in-Editor. Use component to change a component's collision and simulation settings, mesh for static mesh collision, and skel for PhysicsAssets.

For a selected primitive component, physics.inspect_body starts a physics-profile workflow. Use the typed body collision, simulation, gravity, damping, mass, and hit-event tools to prepare it, then run PIE and use the live velocity, wake/sleep, impulse, force, torque, and velocity tools.

Start by discovering the project contract:

physics.get_project_settings {}
physics.list_surface_types {}
physics.list_collision_channels {}
physics.list_collision_profiles {}

Project timing and named surfaces are persistent configuration changes and therefore require confirmation under the normal risk policy:

physics.set_project_settings {"substepping":"true","maxSubstepDeltaTime":"0.008333","maxSubsteps":"8"}
physics.set_surface_types {"surfaces":[{"type":1,"name":"Concrete"},{"type":2,"name":"Mud"}]}

Create the physical material through the asset kit, then tune its response here. density is in g/cm³; friction is non-negative and restitution is from 0 to 1:

asset.create_physical_material {"folder":"/Game/Physics","name":"PM_Rubber"}
physics.duplicate_material {"source":"/Engine/EngineMaterials/DefaultPhysicalMaterial","destination":"/Game/Physics/PM_Ice"}
physics.set_material {"material":"/Game/Physics/PM_Rubber","friction":"1.1","staticFriction":"1.3","restitution":"0.65","density":"1.2","surfaceType":"2","overrideFrictionCombineMode":"true","frictionCombineMode":"max"}
physics.get_material {"material":"/Game/Physics/PM_Rubber"}

Assign the material to a mesh component with component.set_physics, or to a material asset with material.set_physical_material; those tools own the assignment relationship.

While PIE is running, query the runtime world by any listed channel. The queries report only the first blocking response. Pass actor labels in ignoreActors when the trace origin belongs to the player or a probe actor:

physics.line_trace {"start":{"x":0,"y":0,"z":500},"end":{"x":0,"y":0,"z":-500},"channel":"Visibility","ignoreActors":["Player"]}
physics.sweep {"shape":"sphere","start":{"x":0,"y":0,"z":100},"end":{"x":1000,"y":0,"z":100},"radius":25,"channel":"Camera"}
physics.overlap_blocking {"shape":"box","start":{"x":500,"y":0,"z":100},"radius":50,"halfHeight":50,"extentZ":100,"channel":"Visibility"}

Box dimensions use radius, halfHeight, and extentZ as X/Y/Z half extents. A capsule needs halfHeight >= radius. line_trace, sweep, and overlap_blocking require an active PIE world; they intentionally do not run against the editor world.

Test bodies and constraints

The body and constraint tools need a placed actor. To experiment without touching project actors, spawn a movable engine-cube body and a PhysicsConstraintActor (its component is always MyConstraintComp), edit them, then delete them. Engine physical materials are read-only; copy one with physics.duplicate_material before physics.set_material.

physics.spawn_body_actor {"label":"Crate","location":{"x":0,"y":0,"z":300}}
physics.spawn_constraint_actor {"label":"Hinge","actor1":"Crate","location":{"x":0,"y":0,"z":350}}
physics.set_constraint_swing1_limit {"actor":"Hinge","component":"MyConstraintComp","motion":"limited","limit":30}
physics.delete_actors {"actors":["Hinge","Crate"]}

During PIE use the transient variants, which spawn into the play world and initialise the constraint immediately; they disappear when PIE stops:

physics.spawn_test_body {"label":"Crate","location":{"x":0,"y":0,"z":300},"simulate":true}
physics.spawn_test_constraint {"label":"Hinge","actor1":"Crate"}
physics.apply_body_impulse {"actor":"Crate","vector":{"x":0,"y":0,"z":500},"velocityChange":true}
physics.get_constraint_force {"actor":"Hinge","component":"MyConstraintComp"}

physics.delete_actors only removes actors that own a primitive or constraint component (use actor.delete for anything else). Editor-world spawns are undoable; PIE spawns are not recorded.

Tools

Legend. risk 0 = read-only, 1 = harmless editor op, 2 = modifies asset, 3 = deletes/replaces asset, 4 = project/config/build op, 5 = potentially destructive (calls above MaxAutoRisk need "_confirm": true). mutates = runs in a transaction (edit.undo reverts). requires PIE / requires world = refused without a PIE session / an open level. requires plugin = unavailable while the plugin is disabled. dryRun = honours the dryRun argument. smoke = covered by edit.self_test.
