version: "1.0.3" name: unity-physics description: Run Unity physics queries and configure physics at editor time — raycasts, overlap checks, gravity, and physics settings. Use when casting rays, testing overlaps, querying colliders, or adjusting gravity/physics settings, even if the user just says "射线检测" or "物理设置". 执行 Unity 物理查询并在编辑器期配置物理(raycast、overlap 检测、重力、物理设置);当用户要发射射线、检测重叠、查询碰撞体、或调整重力/物理设置时使用。

Physics Skills

Editor-time physics queries (raycast / overlap), gravity, PhysicMaterial assets, and layer collision matrix.

Operating Mode

• Approval：查询类 skill（physics_raycast / physics_check_overlap / physics_get_gravity / physics_get_layer_collision 等，源码标 SkillMode.SemiAuto）直接执行；变更类（physics_set_gravity / physics_create_material / physics_set_material / physics_set_layer_collision，标 SkillMode.FullAuto）需用户 grant，grant 后服务端一步执行返结果。
• Auto / Bypass：所有 skill 直接执行；Auto 走 AI 自我评估，Bypass 全放行。
• 本模块不含 Delete / PlayMode / Reload / 高危 skill，无 Bypass-only 拦截项。
• 注意：所有 skill 都在编辑器线程同步运行。真实物理模拟（积分、碰撞响应）仅在 Play mode 下推进；本模块只做单帧 query + 资产/全局设置写入，不会启动模拟。

DO NOT (common hallucinations):

• physics_add_rigidbody / physics_add_collider do not exist → use component_add with componentType "Rigidbody"/"BoxCollider"/etc.
• physics_simulate does not exist → physics simulation runs during Play mode; this module does not step the simulation
• Raycast results use world-space coordinates

Routing:

• For adding physics components → use component module
• For physics material → use physics_create_material (this module)
• For layer collision matrix → physics_set_layer_collision (this module)

Skills

physics_raycast

Cast a ray and get hit info. Parameters:

• originX, originY, originZ (float): Origin point.
• dirX, dirY, dirZ (float): Direction vector.
• maxDistance (float, optional): Max distance (default 1000).
• layerMask (int, optional): Layer mask (default -1).

Returns: { hit: true, collider: "Cube", distance: 5.2, ... }

physics_check_overlap

Check for colliders in a sphere. Parameters:

• x, y, z (float): Center point.
• radius (float): Sphere radius.
• layerMask (int, optional): Layer mask.

physics_get_gravity

Get global gravity setting. Parameters: None.

physics_set_gravity

Set global gravity setting. Parameters:

• x, y, z (float): Gravity vector (e.g. 0, -9.81, 0).

physics_raycast_all

Cast a ray and return ALL hits (penetrating).

Returns: { count, hits: [{ objectName, instanceId, path, point, normal, distance }] }

physics_spherecast

Cast a sphere along a direction and get hit info.

Returns: { hit, objectName, instanceId, point, distance }

physics_boxcast

Cast a box along a direction and get hit info.

Returns: { hit, objectName, instanceId, point, distance }

physics_overlap_box

Check for colliders overlapping a box volume.

Returns: { count, colliders: [{ objectName, path, isTrigger }] }

physics_create_material

Create a PhysicMaterial asset.

Returns: { success, path }

physics_set_material

Set PhysicMaterial on a collider (supports name/instanceId/path).

Returns: { success, gameObject, material }

physics_get_layer_collision

Get whether two layers collide.

Returns: { layer1, layer2, collisionEnabled }

physics_set_layer_collision

Set whether two layers collide.

Returns: { success, layer1, layer2, collisionEnabled }

Minimal Example

import unity_skills
# Raycast from position downward, check for hits
result = unity_skills.call_skill("physics_raycast",
    originX=0, originY=5, originZ=0,
    dirX=0, dirY=-1, dirZ=0,
    maxDistance=10
)
if result.get("hit"):
    print(f"Hit: {result['hitObjectName']} at distance {result['distance']}")
