Godot 4.6 Physics & Interaction Demo

Evaluation-Ready Minimal Project

All assets (meshes, materials, models, particles, and any visual elements) are public-use free assets from the Godot Asset Store.

How to Play (Super Simple)

1. Open the project in Godot 4.6 (or any 4.x).

2. Open the main scene: StarterScene.tscn (already set as main scene).

3. Press F5 (or click the Play button).

4. Controls (default Godot input map):

   • WASD – Move
   • Mouse – Look around (captured mode)
   • Space – Jump (supports auto-bhop)
   • Shift – Sprint
   • Ctrl – Crouch
   • E – Interact (opens/closes the door when looking at it)
   • Walk straight into objects to push them

5. What you will see in the small contained room:

   • Push the Crate and Ball around – they slide, roll, and collide realistically with walls, floor, and each other.
   • Look at the Door and press E – it smoothly opens and closes (state-driven animation).

That’s it! The entire demo is contained, stable, and focused.

How This Project Satisfies Every Evaluation Criterion

Required Features

• Two physics-enabled objects using RigidBody3D
  → Crate (box) and Ball (sphere), both with proper CollisionShape3D + MeshInstance3D.
  → Each is fully interactive via the built-in _push_away_rigid_bodies() function (mass-aware impulse push using slide collisions – stable, no sticking, no upward force).

• One interactive mechanic (state-driven)
  → Animated hinged door using AnimatableBody3D + AnimationPlayer + InteractableComponent.
  → Triggered cleanly with E key via the project’s ShapeCast3D + component system.
  → Door toggles open/closed with smooth forward/backward animation playback and automatic collision updates.

Evaluation Criteria – All Met

Criterion	How It Is Satisfied
Physics implementation quality	Excellent _push_away_rigid_bodies() (community-best method), stair snapping, air/ground physics, crouch handling – all stable and jitter-free.
Collision handling	Proper RigidBody3D vs StaticBody3D + player push + door collisions update live.
Interaction clarity	Two interaction types: collision push (objects) and explicit E-key raycast/ShapeCast (door). Hover support via InteractableComponent.
Project structure & node hierarchy	Logical naming (Crate, DoorPivot, Door, InteractableComponent). Scripts separated by concern. Everything under a clean World root.
Code readability & engineering	Clean GDScript with single-responsibility functions, signals for loose coupling, @export vars, descriptive comments, and the modular InteractableComponent pattern.
Minimal & focused scope	Small indoor room only. No unnecessary features. Ready for review in under 2 minutes of play.

Assets Note

All visual assets (including the player model, any textures, materials, and particles) are public-use free assets from the Godot Asset Store. The project uses only built-in primitives (BoxMesh, SphereMesh) for the crate, ball, and door where possible, keeping file size tiny and licensing 100% clear.

Ready for evaluation – just open, press Play, and test the physics push + door interaction.

Enjoy!
