Asteroids · deepseek-v4.1-flash

Let me build the game. I'll write a complete index.html with canvas, game loop, asteroids, ship, bullets, lives, score, waves, game over, restart.

Let me just write it carefully.

Let me run it in the browser and inspect.

The game renders. Note the asteroids appear as thin outlines at edges—they're partially offscreen. The ship is at center. No console errors.

But I notice something: the canvas is 900x650 but displayed scaled? The images show canvas taking most of the screen. Fine.

Let me test gameplay: rotation, thrust, firing. I'll use the browser key action. But first I need to focus/click on canvas. Let me click the canvas center.

Actually the browser tool key events probably go to the page. Let me test rotation and thrust, then inspect state via window.__game, but inspect action only returns dom/console. Hmm, I can't run arbitrary JS. Let me use key actions and inspect DOM (score/lives) and screenshot.

Let me test firing: press Space several times, screenshot to see bullets.

Let me do a sequence: click canvas to focus, then key ArrowRight, ArrowUp, Space.

Actually the key tool takes a single key? It has "text" param. Let me check: key action with text probably the key name. Let me try.

Let me test by pressing keys and taking screenshots.

I'll click first at center to ensure focus, then hold is not possible—click once per key press. I can press same key multiple times.

Rotation: press ArrowRight a few times. But each keydown is instantaneous; rotation happens per-frame while key held. The tool's key action may send keydown+keyup. So a single tap rotates only ~one frame. Let me instead check by simulating. Actually to verify rotation I need to hold. The key tool may support holding? Not clear. Let me try "key" with text "ArrowRight" and see.

Alternatively, I can use motion frames after key. Let me just try several key presses rapidly and screenshot.

Actually better: I can test by dispatching events via the browser? No eval tool. But I have window.__game exposed; maybe inspect returns only DOM.

Let me just do key presses and inspect score/lives changes and screenshots.

Let me test thrust: tap ArrowUp many times won't accumulate much. Hmm.

Perhaps the "type" action types text into focused element. Not useful.

Let me check the key action semantics by trying and screenshotting after a delay with motion. The motion action returns frames over time presumably. If I press key ArrowUp then immediately request motion, it captures multiple frames—but keyup already fired.

Let me try holding via multiple keydown? Only one action per call.

Given constraints, I can verify firing (discrete on keydown) and rotation via repeated taps. Let me press Space ~5 times and screenshot to see bullets. Then press ArrowRight many times and screenshot ship heading change.

Let me do it.

The firing worked — a bullet is visible above the ship after Space. Asteroids render nicely. The scene has wrapped: some asteroids are at edges.

Now let me verify rotation. Since key taps are momentary, I can't hold. But I can test via repeated key taps and screenshot. Actually, better approach: the debug hook `window.__game` exists. Maybe the inspect action doesn't run JS, but perhaps I can use a key press sequence. Alternatively I can temporarily add a test harness in the page? Not ideal.

Actually, I could verify rotation logic by reasoning; but the task asks to test rotation, thrust, firing. Firing verified. Let me test rotation by pressing ArrowRight multiple times. Each key press produces one frame of rotation (~3.6*0.016=0.06 rad). Several taps won't visibly change. Hmm.

I could use the "motion" action which might capture frames while a key is held? Not sure. Let me try pressing ArrowUp then immediately motion, to see if thrust persists. Or the browser key action might emulate a real keydown without keyup? The screenshot after Space shows a single bullet, consistent with keydown then keyup (cooldown prevents rapid).

Let me try a different approach: use `type` action? No.

Maybe I can hold key via drag? No.

Alternative: I'll add a small hidden debug test to the page? That changes the artifact. Not desirable.

Actually, I can test the physics logic through the code with node: extract the JS? Simpler: I trust the implementation but let's do a quick sanity via the browser by pressing and holding. Let me check if the key tool supports a "text" that includes key. Hmm.

Let me try: press ArrowUp and then take motion frames immediately. The keydown/keyup may happen within same tick. Let's see what motion returns.

Actually, a cleaner way to test: I can use the browser's JS execution if inspect returns something. It doesn't.

Let me consider using playwright directly via bash? Is there a browser available? Possibly. But time budget. The browser tool is the intended path.

I could inject a test by editing index.html to include a temporary auto-test, run, then remove. That's acceptable but risky. Alternatively, add a small URL/hash-driven test? Overkill.

Better: The key tool likely sends keydown and keyup with a gap? The Space test: fired one bullet, so keydown registered. If I press ArrowUp and then screenshot, the ship's flame may not show since key released. But ship would have moved a tiny bit.

Given the 15 min budget, let me do a practical test: repeatedly press ArrowRight 15-20 times, then screenshot; the ship angle should change noticeably (~1 rad). Each tap perhaps one frame. Let me do a loop of clicks. I can only make one key call per block but can parallelize? Parallel calls may not preserve order. Let me do sequential batches.

Actually, I realize the browser key action might hold the key for the duration until another action, like real automation where keydown and keyup are separate. But the API only has "key" not "keydown"/"keyup". Likely press-and-release.

Let me just try 10 ArrowRight presses sequentially and screenshot. I'll issue them one at a time. That's many tool calls. I can issue multiple in one block but they may run concurrently causing lost events. Let me test a couple.

Actually, I can verify the logic more robustly by writing a temporary test copy (test.html) that imports the same logic? Not needed.

Let me just do 8 sequential ArrowRight presses and a final screenshot. To reduce round trips, I'll do one block with several calls; even if concurrent, some may register. Then screenshot.

Hmm, let me instead trust and do a quick manual verification of rotation using a single long-ish approach: I'll add keyboard hold capability by... no.

Let me test with motion: press ArrowUp, then motion may capture consecutive frames showing movement. Let me try.

Interesting — SCORE 60 and LIVES ▲▲ (lost one life). The bullet hit an asteroid, splitting it (score 60 = size 3*20). Also the ship collided with an asteroid, losing a life. Good — collision/respawn works. Smaller asteroids are visible now. 

Wait, score 60 for one large asteroid = 3*20=60. Correct. And lives dropped to 2, likely from a collision. Good.

Now rotation test. The ship is still pointing up despite ArrowRight tap. As expected, one tap is a fraction of a frame. I need to verify holding. Let me try to use the browser's ability to hold keys — maybe I can dispatch a keydown via the `type` action? No.

Alternative: use a longer press by... The `key` tool signature has only text. Perhaps the text can be a key code and it holds? Unknown.

Let me check if there's a way. Maybe the browser tool supports "key" with text like "ArrowRight" and the harness holds until next action? The screenshot after showed no rotation, suggesting tap.

Since I can't easily hold keys, let me verify rotation logic by using a temporary automated test within the page via a modified copy. Actually, a better idea: I can use the existing `window.__game` and trigger rotation by dispatching synthetic keyboard events from... I can't execute JS.

However, I could temporarily modify index.html to add an auto-test that simulates key holds and logs to console, run it, observe console, then revert. That's a reasonable verification approach. Let me do that carefully but keep final file clean.

Actually simpler: temporarily add at the end of the script a debug that, if location.hash === '#test', programmatically sets keys and steps. But keys is a local variable inside IIFE. I can add a test hook inside the IIFE.

Let me add to __game: `press(code, ms)` that sets keys[code]=true for ms. Then use browser... but I can't call it without JS eval.

Hmm. I need console access. The browser tool inspect returns console logs. So I can add temporary auto-run test code that logs results. Let me do that: append a temporary script that, after load, simulates holding keys by directly manipulating... but `keys` is private. However, I can dispatch real KeyboardEvents on window! keydown with code, and they won't be auto-released. The game listens to window keydown/keyup. So a temporary test script can dispatch keydown events and leave them (no keyup), then measure state over time and console.log.

But that temporary script would also run in the final artifact. So I'll add it, test, then remove.

Actually, even simpler and legitimate: I can keep a permanent small `__game.press` debug hook? Not needed for users. I'll remove after.

Let me create a temporary test snippet appended before </body> (separate script tag), run, check console, then delete it.

Plan for test:
- dispatch keydown ArrowRight
- after 500ms, read __game.getState().ship.angle (should be ~ -PI/2 + 1.8)
- dispatch keyup ArrowRight, keydown ArrowUp
- record position, after 500ms compare and velocity magnitude
- dispatch Space keydown, check bullets length > 0
- log all.

Let me add it.

I need to load the page with #autotest. The browser reload probably loads index.html without hash. Can I navigate to a URL? The browser tool doesn't have a navigate action. Hmm. Maybe reload preserves current URL. Let me just add the test to run unconditionally temporarily instead of gating on hash.

Let me change condition to always run.

The console is empty in the inspect. The test logs after ~1.55s, but inspect was taken at frame 1 immediately. I need to wait then inspect. Let me inspect again after waiting. I'll issue another inspect; but no time delay mechanism. The browser action calls probably have some time between. Let me just call inspect again a couple times.

Actually the initial screenshot at frame 1 shows no asteroids near center — weird, they seem off at edges (one visible at left edge and bottom). spawnWave avoids within 200 of center, fine.

Let me call inspect again.

All three verified:
- Rotation delta=2.160 rad over 600ms (3.6 rad/s * 0.6 = 2.16). 
- Thrust speed=131.4, moved 41.7. 
- Bullets=1, speed 651.4 (bullet speed 520 + ship velocity component). Good.

Also screenshot shows ship rotated to face upper-right and moved from center, and asteroids wrapping at edges. 

Now remove the temp test block. Then do a final reload to confirm clean and no console errors.

Let me remove the test code.

Now final reload to confirm no console errors and game runs. Also I should verify Game Over/restart. With the debug hook removed? I kept window.__game, which is harmless. Let me keep it.

Test game over + restart: I could temporarily force lives to 0? Not easily without eval. But I can play and crash repeatedly... time consuming. I could re-add a temp test to force collision? Given budget, let me do a quick temp test: dispatch keydown to make ship sit still while asteroids come; not deterministic.

Alternatively, temporarily set lives low via test hook. Let me add a small temp test that sets state... but lives is private. __game only has getState. I could temporarily expose a setter. That's more edits.

Given the collision/life-loss already observed (LIVES went from ▲▲▲ to ▲▲), and the game-over code path is straightforward, I'll verify the overlay/restart by simulating three life losses through a temporary test that repeatedly forces ship into asteroid positions? Hard.

Simpler: temporarily add a hook `__game.kill = () => { lives = 0; ... }`? Actually easiest: temp test that dispatches nothing but directly calls the game-over branch by exposing an internal function. Let me just add temporarily a `window.__forceGameOver` inside IIFE that does lives=0; gameOver=true; overlay show; and test restart button click. Then remove.

But the restart function resets. Let me do a focused temp test:
- call forceGameOver()
- read overlay visible & gameOver
- click restart button
- check score 0 lives 3 gameOver false.

Let me do it. Add temp hook and a console log test, reload, inspect, then remove.

Actually maybe faster: test via DOM clicking isn't possible to check gameOver. But I can check overlay display via inspect DOM? inspect returns innerText only, not attributes. Console log is better.

Let me add it.

Game Over flow and restart both work: over=true overlay=true, then after restart score=0 lives=3 over=false overlay=false asteroids=6. 

Now remove the temp test and do a final reload.

Final clean reload: no console errors, score 0, lives 3, asteroids spawning at edges. Game works.

Let me confirm the temp code is gone by grepping.
