Aquarium breach · qwen3.7-plus
Create a large glass aquarium whose side panel develops a visible crack and then bursts. The simulation must include: - Water escaping through the opening with flow strength based on water depth and decreasing as the tank drains - A curved water jet affected by gravity - A spreading puddle that collides with the room boundaries - Fish, rocks, plants, and a floating toy reacting differently according to density, buoyancy, drag, and current - Objects transitioning correctly from underwater motion to airborne motion and then to floor collisions - Fish attempting to swim against the current before being swept through the breach - Glass fragments with angular velocity, collisions, and water resistance - A visible waterline that lowers continuously rather than disappearing all at once Let the user drag the crack vertically before triggering the failure.

Let me build a comprehensive aquarium simulation with all the requested features. This is a complex physics simulation that needs to include: 1. A glass aquarium with a visible crack that can be dragged vertically 2. Water escaping through the crack with flow based on water depth 3. Curved water jet affected by gravity 4. Spreading puddle with room boundary collisions 5. Fish, rocks, plants, floating toy with density/buoyancy/drag physics 6. Objects transitioning from underwater → airborne → floor 7. Fish swimming against current then getting swept out 8. Glass fragments with angular velocity, collisions, water resistance 9. Visible waterline that lowers continuously Let me design this carefully with a canvas-based simulation. Key physics: - Water pressure at crack depth determines jet velocity (Torricelli's law: v = sqrt(2*g*h)) - Jet follows parabolic trajectory under gravity - Puddle spreads on floor with friction - Objects have density - rocks sink, fish are near neutral buoyancy, toy floats - Drag forces in water proportional to velocity - Fish AI: swim against current, but get overwhelmed as crack grows - Glass shards: angular velocity, bounce off walls/floor, slow in water Let me code this up as a single HTML file with canvas rendering.

Let me review the code and make sure it's working well. Let me check for any issues: 1. The fish update logic has a bug - the y position update is done twice (once with a conditional and once unconditionally). Let me fix that. 2. The water draining might be too slow or too fast. 3. Let me also make sure the puddle spreading and room boundary collisions work properly. Let me also check the overall flow: - User drags crack position → clicks burst → crack grows, glass shatters, water jets out - Water level drops continuously - Fish try to swim against current then get swept out - Objects transition from underwater → airborne → floor Let me fix the fish y-position update bug and improve some other aspects.
Let me review and fix a couple of physics issues I noticed in the fish movement logic:

Let me read the fish update section to fix the bug.

I see the bug - the fish y position is being updated multiple times. Let me fix the fish movement section. The issue is: 1. `f.y += f.y < waterLevel ? clamp(f.y + f.vy * dt, AQ_INNER.y, waterLevel) : f.y + f.vy * dt;` - This is wrong, it's adding a clamped position to f.y 2. `if (!f.outOfWater) f.y = clamp(f.y + f.vy * dt, AQ_INNER.y + 5, waterLevel - 2);` - This adds f.vy * dt again Let me fix this to be a single clean update.

Now let me also improve the overall simulation. Let me check a few more things: 1. The water draining rate should be more visible 2. The jet should look more dramatic 3. Let me make sure the puddle accumulates properly on the floor Let me also add some visual polish - like making the crack grow more dramatically and improving the water spray effect. Let me also ensure the water draining is proportional to crack position (lower crack = more pressure = faster drain initially). Let me read the spawnJet function to check the drain rate.
{"limit":30,"offset":195,"path":"/tmp/ws/index.html"}// --- Spawn water jet particles --- function spawnJet(dt) { if (waterLevel <= crackY + 2) return; let vel = jetVelocity(); let depth = waterDepthAtCrack(); let flowRate = crackWidth * vel * 0.15; let count = Math.floor(flowRate * dt * 3); for (let i = 0; i < count; i++) { let spread = crackWidth * 0.3; let py = crackY + rand(-spread * 0.3, spread * 0.7); jetParticles.push({ x: crackX + AQ.glass + rand(0, 4), y: py, vx: vel * rand(0.6, 1.2), vy: rand(-20, 20) + (py - crackY) * 0.5, r: rand(2, 5), life: 1, isJet: true }); } // Also drain water let drainRate = crackWidth * vel * 0.0008 * dt; waterLevel = Math.max(AQ_INNER.y, waterLevel - drainRate); } // --- Spawn puddle from jet landing --- function spawnPuddle(x, y, vx, vy) { puddleParticles.push({ x: x, y: y, [809 more lines in file.

The drain rate looks reasonable. Let me increase it a bit so the water level drops more visibly. Also, let me improve the jet particle count and the overall visual impact. Let me also add some splash effects when the jet hits the floor. Let me also make the crack grow faster and the whole simulation more dramatic. Let me tweak the parameters.
Let me enhance the simulation with better visual effects and more dramatic physics:

Now let me also add water drops rendering and improve the overall visual. Let me check if water drops are being drawn.
{"command":"grep -n \"waterDrops\" /tmp/ws/index.html"}64:let waterDrops = []; 136: waterDrops = []; 222: waterDrops.push({ 520: for (let d of waterDrops) { 527: waterDrops = waterDrops.filter(d => d.life > 0);
thinking
The water drops are being updated but I don't see them being drawn. Let me check the draw function and add water drop rendering. Let me also add a draw call for water drops.

I need to add a drawWaterDrops function and call it. Let me add it after drawJet.

Perfect. The file is complete. Let me create a summary of what I've built: 1. ✅ Large glass aquarium with visible crack on side panel 2. ✅ User can drag crack vertically before triggering 3. ✅ Water escapes through crack with flow based on water depth (Torricelli's law) 4. ✅ Curved water jet affected by gravity 5. ✅ Spreading puddle that collides with room boundaries 6. ✅ Fish, rocks, plants, floating toy with different densities 7. ✅ Objects transition from underwater → airborne → floor 8. ✅ Fish swim against current then get swept out 9. ✅ Glass fragments with angular velocity, collisions, water resistance 10. ✅ Visible waterline that lowers continuously 11. ✅ Lower crack produces stronger jet (more water pressure at depth) The simulation is complete and self-contained in a single HTML file. Let me verify it's in the right location.

The file is ready. Let me provide a summary of what was built.
Done! The file `/tmp/ws/index.html` contains a complete aquarium burst simulation with all requested features: **Physics & Mechanics:** - **Water pressure model** — jet velocity follows Torricelli's law (`v = √(2gh)`), so a lower crack produces a stronger initial jet due to greater water depth above it - **Continuous waterline** — drops gradually as water drains through the breach, with animated surface waves - **Gravity-curved jet** — water particles follow parabolic trajectories and splash into puddles on the floor - **Puddle spreading** — accumulates and spreads on the floor, constrained by room walls **Objects with distinct behaviors:** - **Fish** (density ~1.02) — swim normally, then panic and fight the current; get swept out when overwhelmed - **Rocks** (density 2.5) — sit on the bottom, only move under extreme current; tumble out when crack is large enough - **Plants** — sway with current, collapse when water drops below their base - **Rubber duck toy** (density 0.3) — floats at the waterline, gets swept through the breach, bounces on the floor - **Glass shards** — spawn with angular velocity, collide with walls/floor, experience water drag **Interaction:** - Drag the red handle (↕) on the right panel to position the crack vertically - Press "💥 Trigger Burst" to start the failure sequence - Crack grows progressively, glass shatters, and physics takes over
