Core Game Loop and Mechanics

This is a physics prototype focused on demonstrating realistic ragdoll simulation. The player observes a ragdoll character standing on a platform, and can test the physics by firing rocks at it using a debug button.

Moment-to-moment gameplay:

A ragdoll character stands on a platform
Player clicks the "Fire Rock" button to launch a projectile
The rock flies toward the ragdoll and impacts it
The ragdoll reacts realistically to the impact, potentially falling or stumbling
Player can fire multiple rocks to observe different physics interactions

What makes it engaging:

Satisfying physics reactions and ragdoll movements
Experimenting with different impact points and forces
Watching the ragdoll recover or collapse in realistic ways

Starting Scope

For this initial prototype, implement:

A single ragdoll character composed of geometric primitives
A solid platform for the ragdoll to stand on
Physics simulation with realistic collisions and constraints
A debug button that fires rocks at the ragdoll
Basic camera view showing the entire scene

NOT included in this iteration:

Slingshot mechanics
Multiple characters
Game loop, scoring, or win/lose conditions
Edit mode
UI beyond the debug button
Title screen or menus

Game Perspective

fixed-screen - Single screen view showing the platform and ragdoll character. The camera is positioned to show the full scene with the platform centered.

Game World and Level Design

Scene Layout:

A single horizontal platform (3:1 aspect ratio rectangle) positioned in the lower-middle portion of the screen
One ragdoll character standing upright on the platform
Rocks spawn off-screen and travel toward the ragdoll when fired

Physics Environment:

Gravity pulls objects downward
All solid objects have collision detection (ragdoll parts, platform, rocks)
Ragdoll joints have constraints to simulate realistic body movement
Rocks have sufficient mass and velocity to create visible impact

Edit Mode Design

No edit mode in this prototype iteration.

Control Design

Desktop:

Mouse click on "Fire Rock" button to launch a projectile

Mobile:

Tap "Fire Rock" button to launch a projectile

Debug Mode:

config.debugOn (boolean) - When true, displays the "Fire Rock" button
Default: true

Art Style and Visual Theme

Minimalist Geometric Style:

All shapes rendered using Canvas/CSS - no generated image assets needed
Clean, solid colors with no textures
Simple anti-aliased shapes

Ragdoll Character Composition:

Head: Circle (medium size)
Torso: Rounded rectangle (vertical orientation, larger than head)
Upper arms: Thin rounded rectangles/pills (connected to shoulders)
Lower arms: Thin rounded rectangles/pills (connected to elbows)
Upper legs: Thin rounded rectangles/pills (connected to hips)
Lower legs: Thin rounded rectangles/pills (connected to knees)

Color Palette:

Ragdoll: Warm skin tone (#F4C2A0 or similar)
Platform: Brown/tan (#8B7355)
Rocks: Dark grey (#555555)
Background: Light blue sky (#87CEEB)
Button: Simple UI color (white background, dark text)

Technical Rendering:

Use Canvas 2D API for all rendering
Ragdoll joints should be visible as connection points
Smooth anti-aliased edges on all shapes
Simple shadows or outlines optional for depth

Physics Implementation Details

Ragdoll Structure:

Use a physics engine (Matter.js from CDN) for realistic simulation
Each body part is a rigid body with appropriate mass
Joints connect body parts with constraints:
- Neck: Head to torso
- Shoulders: Upper arms to torso
- Elbows: Upper arms to lower arms
- Hips: Upper legs to torso
- Knees: Upper legs to lower legs
Joint constraints should allow realistic range of motion but prevent unnatural bending
Ragdoll starts in a standing pose with slight joint stiffness to maintain posture

Collision System:

All body parts have collision detection enabled
Platform is a static rigid body
Rocks are dynamic rigid bodies
Collision response should be realistic (bounce, friction, energy transfer)

Rock Projectile:

Small circle (radius ~20-30 pixels)
Spawns off-screen to the left or right
Fires horizontally toward the ragdoll's center mass
Sufficient velocity to create visible impact (~15-25 units/second)
Mass appropriate for realistic physics interaction

Debug Button:

Positioned in top-right corner of screen
Large enough for easy touch interaction (96x96 minimum)
Clear label: "Fire Rock"
Each click spawns and fires one rock
