Phyzzy - Pixel Physics Sandbox

What is Phyzzy?

Phyzzy is a pixel-based physics playground with little villagers that go POP! Every dot on the screen behaves like a real material. Draw with different elements, water, fire, stone, lava, and watch them interact in realistic ways. Set your own resolution and have fun! 😊 

How It Works

Every pixel is a particle with its own properties. Some are solid, others flow like liquids, some rise like smoke. Each type has rules about how it interacts with neighbors, creating complex behaviors from simple rules.

What You Can Do

• Draw with over 20 particle types
• Watch physics in action, water flows, fire spreads, sand piles
• Create chain reactions, light a fuse, trigger TNT, burn wood
• Build structures, dams, walls, houses
• Generate worlds, random terrain with mountains, rivers, caves
• Save your creations!

Key Features

Particle	Behavior
💧 Water	Flows downhill, can be frozen or boiled
🔥 Fire	Spreads to flammables, creates smoke
🟫 Soil	Basic building block, erodes
🟨 Sand	Flows like granular material
🪨 Stone	Sturdy, melts in lava
🪵 Wood	Flammable, burns slowly
🟤 Oil	Floats on water, highly flammable
🌋 Lava	Extremely hot, melts stone, creates steam
💨 Smoke	Rises from fires and explosions
♨️ Steam	Rises through water and lava
🧊 Ice	Melts near heat
🟢 Acid	Corrodes materials, dissolves in water
🧨 Fuse	Burns like a wick, triggers TNT
💣 TNT	Explodes when ignited
🎆 Firework	Creates colorful sparks
☁️ Cloud	Floats, turns into water
🕳️ Void	Vanishes when burned by a fuse
🧪 Catalyst	Turns water into acid
🧍 Villager	Walks around, avoids fire/lava/acid, can dig, and right‑click to assign jobs!
🔶 Portal IN	Orange portal: sucks in nearby particles and teleports them to the blue portal (can have many orange portals)
🔷 Portal OUT	Blue portal: pushes particles out and receives teleported particles

Villagers & Jobs

• 🧍 Villager, Place them with the Villager tool. They walk, avoid hazards (fire, lava, acid), and will flee or dig to survive.
• Right‑click a villager to assign a job:
  • ⛏️ Digger, digs straight down
  • ⚒️ Miner, tunnels sideways in the direction they face
• When a villager dies, they shout and burst into a red mist.

Save / Load

• Save, stores your entire simulation (grid, particles, sprites, camera, settings)
• Load, restores a previously saved simulation.
• Delete, removes the saved data.
• Keyboard shortcuts: Ctrl+S save, Ctrl+O load.

Portals

• 🔶 Orange (IN), place multiple. They suck particles in and teleport them to the blue portal.
• 🔷 Blue (OUT), only one allowed. Particles emerge here, pushed outward.
• Use the portal buttons in the right sidebar or press P to enter portal placement mode.

Special Features

• Earthquake, Press E to trigger massive terrain shifts (chasms, lava pools, debris).
• Terrain Generation, Click 🎲 for random worlds with biomes, caves, rivers, and more.
• Meteor Shower, Click ☄️ to rain fiery meteors that explode on impact.
• Emitter Tool, continuous particle spawner (choose material).

⌨Keyboard Shortcuts

• Space Pause/Resume
• G Toggle Gravity
• R Generate Terrain
• E Earthquake
• C Clear Canvas
• P Toggle Portal Placement Mode
• Delete or D Clear All Portals
• + - Zoom In/Out
• 0 Reset Zoom
