godot-physics

godot-physics is a skill for Claude Code from gamedev-skills/awesome-gamedev-agent-skills. It costs 130 tokens per session (2,468 once invoked), scanned A, original, Apache-2.0.

A guide to physics in Godot 4.7, the game engine, for objects and collision detection in two- and three-dimensional games. It explains body types, collision layers and masks, overlap detection, forces, and raycasts.

In plain words
What is it for?
Use it to set up floors and walls, simulated objects, player-controlled bodies, trigger areas, hurtboxes, line-of-sight checks, and ground checks.
Why use it?
It helps ensure that game objects collide with the right things and that detection behaves as intended.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

godot-physics scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Godot Physics (4.x, 2D + 3D)

Pick the right physics body, wire up collision layers/masks, detect overlaps, and cast rays. Concepts apply to both 2D and 3D (swap the 2D/3D suffix). Targets Godot 4.7. In 3D, projects created with Godot 4.6 or later run Jolt Physics by default; older projects keep GodotPhysics3D unless someone switched them. 2D always uses Godot's own 2D engine.

When to use

  • Use when choosing between body types, setting collision layers/masks so the right things collide, detecting overlaps (triggers, hurtboxes) with Area, applying forces/impulses to a RigidBody, or casting rays for line-of-sight/ground checks.

When not to use: kinematic character controllers (move_and_slide) → godot-2d-movement; tile collision setup → godot-tilemap; tuning the feel of physics (timestep, mass, jitter) → physics-tuning.

Core workflow

  1. For 3D, check which engine runs before debugging behavior: Project Settings > Physics > 3D > Physics Engine ([physics] 3d/physics_engine="Jolt Physics" in project.godot). Projects created in 4.6+ get Jolt written there by default; with no such line (DEFAULT) the engine is GodotPhysics3D. The API is the same, but joints, ray-cast face indices, kinematic contacts, and collision margins behave differently (see Pitfalls).
  2. Choose the body type:
    • StaticBody — never moves (floors, walls). Collides, no simulation.
    • RigidBody — fully simulated (gravity, forces, bouncing). Don't set its position directly; apply forces/impulses or set linear_velocity.
    • CharacterBody — script-driven kinematic (see godot-2d-movement).
    • Area — detects overlaps and can apply gravity/damping; no solid collision. Every body needs a CollisionShape (or CollisionPolygon) child.
  3. Configure layers and masks. A body is on its layers and scans for its masks. Two bodies interact only if one's layer is in the other's mask. Name layers in Project Settings > Layer Names for clarity.
  4. Detect overlaps with Area signals (body_entered, area_entered).
  5. Drive RigidBodies with forces/impulses, or override _integrate_forces for full control.
  6. Cast rays with a RayCast2D/3D node (polled each frame) or a one-shot space-state query from code.
