Asteroids · mistral-large-4-0

The game renders: ship at center, 4 large asteroids, HUD, controls. Now test rotation, thrust, firing.

The key events may not have registered as held keys (the tool sends key events but the ship doesn't appear to move much — it's still near center pointing up). The ship appears unchanged across frames. The `key` action may send keydown+keyup quickly, so no sustained movement. Let me instead verify game logic programmatically by injecting JS via the browser — but the browser tool doesn't have an eval action. I can use `type` to type into the page? That won't help. Alternative: use `drag`? No. The `key` action likely presses and releases. For held keys, maybe I should check whether the tool supports holding. The motion frames show asteroids moving (they drifted), but the ship stayed at center pointing up — meaning ArrowRight/ArrowUp/Space had no lasting effect, consistent with press-and-release. To verify rotation/thrust/firing, I can temporarily add a test harness: modify the page to expose state, or simulate by dispatching events. Better: use the browser's ability — maybe `type` with text dispatches key events? Unclear. A pragmatic approach: write a small test by loading the page with a query that auto-plays? Simpler: temporarily patch index.html to add a self-test that runs on load (e.g., sets keys programmatically and logs state to console), run inspect, read console, then remove the test code. Console messages appear in the inspect output. Let me add a temporary self-test script that: 1. Records initial ship rot/x/y. 2. Sets keys["ArrowRight"]=true, steps update manually? The loop is internal. Instead, I can simulate by directly calling the internal functions — but they're in a closure... Actually the script is at top level (not wrapped in IIFE), so `ship`, `keys`, `update` are global (declared with let/const at top level of a classic script — `let`/`const` at top level are NOT on window but ARE in global scope accessible to other scripts). So a second script tag can access them. Plan: add a temporary `<script>` after the main one that runs a test: - log initial rot - keys["ArrowRight"] = true; manually call update(0.5) a few times; log rot change - keys["ArrowUp"] = true; update; log vx/vy - keys[" "] = true; update; log bullets.length - test wrap: set ship.x = W - 5, ship.vx = 100; update(0.2); log ship.x (should wrap to small value) - test asteroid split: place asteroid in front of ship, fire bullet at it... simpler: call destroyAsteroid(0) and log asteroids count change and score. - test life loss: set ship.invuln=0, teleport asteroid onto ship, update, log lives. - test game over: set lives=1, repeat, check gameOver and overlay shown. - test restart: click restartBtn, check score/lives reset. But update() uses dt and performance.now for shooting cooldown — fine. Note: the main loop is also running via requestAnimationFrame, which will interfere (it calls update with real dt). That's okay; tests still valid approximately. But rAF may not fire in headless? The motion frames showed asteroids moving, so rAF fires. Also careful: my test mutating state while loop runs could cause game over mid-test. I'll set paused = true during tests to stop the loop's update (update returns early if paused). But then my manual update() calls also return early! Because update checks paused. Hmm. Instead set gameOver? Same issue. Alternative: don't pause; just run tests quickly and tolerate interference. Or temporarily stop the loop: I can't cancel rAF easily since id not stored. I could override requestAnimationFrame before... the main script already ran. Simplest: in test script, set `paused = true` and call the internal pieces directly? update() early-returns when paused. I could instead replicate: temporarily set paused=false, run test synchronously (JS is single-threaded; rAF callbacks can't interleave synchronous code). So: run all tests synchronously in one script — rAF won't fire during synchronous execution. So the test script runs synchronously: set keys, call update(dt) manually multiple times, check state, all before any rAF tick. The loop's lastTime was set; when rAF resumes it'll just continue. Fine. Let me write the test script, append to index.html temporarily, inspect, then remove. Test details: ```js <script> (function(){ const log = []; const L = (...a) => { log.push(a.join(" ")); }; const startRot = ship.rot; keys["ArrowRight"] = true; update(0.5); L("rot after ArrowRight 0.5s:", ship.rot.toFixed(3), "start:", startRot.toFixed(3), "changed:", Math.abs(ship.rot - startRot) > 0.5); keys["ArrowRight"] = false; keys["ArrowUp"] = true; const px = ship.x, py = ship.y; update(0.5); L("thrust: moved", Math.hypot(ship.x-px, ship.y-py).toFixed(1), "speed", Math.hypot(ship.vx, ship.vy).toFixed(1)); keys["ArrowUp"] = false; // firing const nb = bullets.length; keys[" "] = true; lastShot = -1; update(0.05); L("bullets before/after fire:", nb, bullets.length); const b = bullets[bullets.length-1]; const bx = b.x, by = b.y; update(0.2); L("bullet moved:", Math.hypot(b.x-bx, b.y-by).toFixed(1), "life:", b.life.toFixed(2)); // bullet lifetime bound let t = 0; while (bullets.includes(b) && t < 5) { update(0.1); t += 0.1; } L("bullet expired after", t.toFixed(1), "s:", !bullets.includes(b)); keys[" "] = false; // wrap test ship.x = W - 2; ship.y = 100; ship.vx = 200; ship.vy = 0; ship.invuln = 0; update(0.1); L("wrap: x from", (W-2), "->", ship.x.toFixed(1), "wrapped:", ship.x < 50); // asteroid wrap asteroids[0].x = 5; asteroids[0].y = 100; asteroids[0].vx = -100; asteroids[0].vy = 0; update(0.1); L("asteroid wrap x:", asteroids[0].x.toFixed(1), "wrapped:", asteroids[0].x > W - 50); // split test const s0 = score, n0 = asteroids.length; const big = asteroids.find(a => a.size === 0) || asteroids[0]; const bi = asteroids.indexOf(big); destroyAsteroid(bi); L("split: count", n0, "->", asteroids.length, "score", s0, "->", score); // collision / life ship.invuln = 0; const a0 = asteroids[0]; a0.x = ship.x; a0.y = ship.y; a0.vx = 0; a0.vy = 0; const l0 = lives; update(0.01); L("collision: lives", l0, "->", lives, "ship invuln:", ship.invuln.toFixed(2)); // game over lives = 1; const a1 = asteroids[0]; ship.invuln = 0; a1.x = ship.x; a1.y = ship.y; update(0.01); L("gameOver:", gameOver, "overlay shown:", overlay.classList.contains("show")); // restart restartBtn.click(); L("after restart: score", score, "lives", lives, "wave", wave, "asteroids", asteroids.length, "overlay hidden:", !overlay.classList.contains("show")); console.log("SELFTEST\n" + log.join("\n")); })(); </script> ``` Wait — issue: `update` early-returns if gameOver or paused. During tests fine. But after restart click, newGame resets. Also note: after game over test, ship.alive=false; restart resets. One catch: in the collision test, after loseLife, resetShip sets invuln=2. Good. Another catch: `update(0.5)` with ArrowRight — but the ship might collide with an asteroid during these big steps and lose a life, messing later assertions. Ship starts at center with invuln=2s; update(0.5)+update(0.5) = 1s < 2s, so invulnerable during rotation/thrust tests. Good. But thrust moves ship toward an asteroid possibly — invuln protects. invuln decrements: after 1.0s total, invuln=1.0. Then firing tests use small steps. Then I set ship.invuln=0 manually before wrap test. But wrap test teleports ship to (W-2, 100) — could an asteroid be there? Possibly; then collision → loseLife → lives 2, ship respawns at center, and my "wrap" assertion on ship.x fails. To be safe, clear asteroids first: `asteroids.length = 0`? But then "asteroids.length===0 && !gameOver" triggers next wave spawn at end of update! spawnWave(3+wave) adds asteroids and resets ship. That would break tests. Better: before wrap tests, move all asteroids far away and set their velocities to 0: `for (const a of asteroids){ a.x=50; a.y=50; a.vx=0; a.vy=0; }` — but ship teleported to (W-2,100) is far from (50,50). Distance ~850 > collision. OK. But wait, during update, asteroids at (50,50) with vx=0 stay. Ship at right edge moving right wraps to left side x≈18. Distance from (50,50): ship y=100, dx≈32, dy=50 → ~59 > r+12 (~58)? Large asteroid r=46 → 46+12=58. 59 > 58 barely. Risky. Move asteroids to (50, 550) instead — far from both ship positions (y=100). Distance from wrapped ship (18,100) to (50,550): dy=450. Safe. And from (W-2,100): safe. Also the split test: destroyAsteroid spawns 2 smaller asteroids at the destroyed one's position (50,550) — far from ship. Good. Collision test: asteroids[0] teleported onto ship. But asteroids[0] might be a small piece from split at (50,550) — fine, teleport it. Also note the wave-clear check: after split test, asteroids.length = n0-1+2. Not zero. Good. But careful: if n0 was 1... initially 4 asteroids, minus wrap-test none removed, split removes 1 adds 2 → 5. Fine. Also during the bullet lifetime test (loop up to 5s of updates in 0.1 steps), ship has invuln... I set keys[" "]=false after. During those updates, asteroids at (50,550) static, ship somewhere — no collision. But wait: bullets wrap and could hit asteroids at (50,550)? Bullet fired from ship position toward heading; after 1.1s bullet dies. It might hit an asteroid → destroyAsteroid → score changes, fine, doesn't break assertions. But it could also... the bullet test asserts bullet expired — if bullet hits asteroid it's spliced early; `bullets.includes(b)` false → "expired" true anyway. Fine. Also during bullet test, ship.invuln may still be >0 (set 0 only later). OK. One more: the thrust test — after rotation test, ship.rot changed by ~1.7 rad. Thrust moves in new heading. Fine. Also `lastShot = -1` — lastShot is declared with `let` at top level; accessible. `performance.now()/1000 - (-1)` > cooldown. Good. Also the rAF loop: during synchronous test, no ticks. After test ends, loop continues with dt clamped to 0.05. Fine. Console output: the inspect tool shows console messages. console.log with newlines should appear. Let me add this test script temporarily.

Mostly passing. Two "wrapped: false" results — but look at the values: - SHIP WRAP: x 898 -> 917.3. W=900. Ship moved from 898 by vx=200*0.1=20 → 918, minus friction. wrapPos: `if (o.x > W + o.r) o.x = -o.r;` — ship r is undefined! `wrapPos(ship)` uses `o.r` which is undefined for the ship → `W + undefined = NaN`, comparisons false, so ship never wraps! Bug. Ship has no `r` property. 917.3 > 900 — off screen. Need to fix: give ship an r (e.g., 14) or use a fixed margin. - ASTEROID WRAP: x 5 -> -5.0. Asteroid moved left from 5 by 100*0.1=10 → -5. wrapPos: `if (o.x < -o.r) o.x = W + o.r;` — -5 < -46? No. So it stays at -5, partially off-screen, and will wrap once x < -46. That's actually correct behavior (wrap when fully off screen). My test threshold was wrong, not the code. Asteroid at -5 is still visible (radius 46), so it's fine — it wraps when fully past the edge. Actually the requirement says "asteroids also wrap" — wrapping when fully off-screen is standard and fine. But the test asserted wrapped after only 0.1s; the asteroid needs to travel 51px more. Not a bug. But the ship wrap IS a bug: ship.r is undefined → NaN comparisons → ship never wraps. Fix: add `r: 14` to ship object in resetShip. Also check bullet wrap: bullets have r: 3, fine. Fix resetShip to include r: 14. Then re-run self-test with adjusted asteroid wrap test (give it more time or check x > W - r after enough travel: from x=5, vx=-100, need x < -46 → travel 51px → 0.51s. Use update(0.6) → x ≈ 5 - 60 = -55 < -46 → wraps to W + r ≈ 900+46=946? Wait wrap sets x = W + o.r = 946, then next frames move it left into view. Hmm, that places it just off the right edge, correct. Actually wait — for the ship, with r=14: ship at 898, vx=200, dt=0.1 → x≈917.3 (with friction ~917). W + r = 914. 917.3 > 914 → wraps to -14. Test threshold ship.x < 60 → true. Good. Let me fix and also update the asteroid wrap test to run 0.6s.
