Top-down alien shooter · deepseek-v4.1-flash

Let me start by checking the environment and the phaser.min.js file.

Let me check the Phaser version.

Phaser 3.80.1. Let me build the game. I'll write a self-contained index.html.

Let me plan the game:
- Arena with bounds
- Player: a procedurally generated texture (circle/triangle ship) with arcade physics
- WASD movement
- Aim toward pointer: rotate player to face pointer
- Fire with left mouse button (with cooldown)
- Bullets: fired toward pointer direction
- Aliens: spawn in waves, advance toward player
- Collisions: bullet-alien damage, alien-player damage
- Health, score, wave display
- Game over with restart
- Restart restores everything

I'll use a fixed-size canvas maybe 900x600, with a border. Use Phaser scale FIT.

Let me generate textures using graphics.generateTexture.

I'll write the code carefully.

Key details:
- Player speed 220
- Bullet speed 520
- Alien speeds increasing per wave
- Score +10 per kill
- Health 100, alien contact damage 10 with brief invulnerability
- Wave cleared when all aliens dead -> next wave

Let me create a clean implementation.

For aiming: rotation = Phaser.Math.Angle.Between(player.x, player.y, pointer.worldX, pointer.worldY). Player texture pointing right (0 rad).

Firing: use pointer.leftButtonDown() or on pointerdown. I'll support holding by checking input.activePointer.leftButtonDown() in update.

Let me generate textures:
- player: triangle/ship shape in a 32x32 texture. Draw pointing right.
- alien: circle with details, 28x28.
- bullet: small glowing circle/rect.

Use graphics.generateTexture('player', 40, 40). Draw within centered.

Let me write.

Actually with generateTexture, need to draw at coordinates and then destroy graphics.

Let me build UI with Phaser text, fixed to camera (setScrollFactor(0)). Since world is same size as canvas no scrolling needed, but fine.

Health bar as graphics + text.

Let me write the file.

I'll make canvas 960x640. Player starts center. Arena bounds with a border drawn via graphics.

Aliens spawn just inside edges away from player.

Wave scaling: enemy count = 4 + wave*2, speed = 60 + wave*12.

Let me implement.

For visible hit feedback: alien flashes tint, small particle burst, camera shake maybe. Use tween on tint or setTint then clear. Also a hit spark.

Let me write the full file now.

I'll include instructions on screen: "WASD Move | Mouse Aim | Left Click Fire".

Game over overlay: dark rect, text "GAME OVER", score, "Click Restart or press R". Restart button.

Let me code.

Careful with Phaser 3.80 API:
- this.physics.add.group()
- group.get() etc. I'll manage arrays manually.

Bullets group: this.bullets = this.physics.add.group({ classType: ...}) Actually easier: create sprite and add to group. Use physics group with maxSize maybe.

let me just use this.physics.add.group() and bullets.create(x,y,'bullet').

Collider between bullets and aliens: this.physics.add.overlap.

Alien-player overlap.

Let me write.

For invulnerability, track lastDamageTime.

Let me also make player kill aliens on contact? No, contact damages player and push alien back or destroy alien? Typically alien contact damages player; I'll destroy the alien too to avoid repeated damage, or keep it. I'll destroy the alien on contact and damage player. Simpler and prevents multi-hit.

Actually to make it more playable, alien contact damages player and destroys the alien.

Let me implement a health bar.

Now code:

```js
const W = 960, H = 640;
const config = {
  type: Phaser.AUTO,
  width: W, height: H,
  parent: 'game',
  backgroundColor: '#05060a',
  physics: { default: 'arcade', arcade: { debug: false } },
  scene: { create, update }
};
```

Wait, need scene class. I'll define a Scene class.

I'll write it.

Procedural textures via a helper in create.

Player texture: ship shape pointing right. Points: (38,20),(4,6),(12,20),(4,34) -> a dart.

Alien texture: circle radius 14 center (18,18), plus inner circle and spikes. size 36.

Bullet texture: 12x6 capsule-ish with glow, pointing right. I'll draw a rectangle and set rotation same as player.

Effects: orange particle texture 8x8.

Let me write the file.

Movement normalization for diagonal.

Also clamp player to world bounds: player.setCollideWorldBounds(true); physics world bounds default canvas.

For pointer worldX — since camera not scrolled, x/y same.

Restart: this.scene.restart() and reset registry values. I'll keep game state as scene properties reset in create.

Game over: set this.gameOver = true, stop physics (this.physics.pause()), disable input for firing. Show overlay container. Restart button interactive.

Let me write code now.

I'll add a world border drawn graphics.

Let me create index.html.

The game renders. HUD shows Health 100/100, Score 0, Wave 1. 5 aliens spawn (3 + 1*2 = 5). Good.

Let me test movement and firing. I'll click somewhere to aim and fire. The viewport is 1200x800 but canvas is centered and scaled. Let me test by clicking to the right of player.

Let me do a click at a point. The player is around x=600,y=520 in the screenshot? Actually screenshot is 1200x800, canvas fits. The pointer positions in browser tool use 1200x800 viewport. The canvas spans roughly x=120 to 1080, y=78 to 730. Player at center ~600,400? In screenshot player at ~600,520. Hmm screenshot is scaled. Actually Phaser FIT to 1200x800 would scale 960x640 to 1200x800 exactly (ratio 1.25). Border starts at 120,80 and ends 1080,720. Player center = 600,400. But screenshot shows player at 600,520. Wait that's odd.

Let me look again: player appears at y~405 in the 800-tall image? The screenshot attached is 1200x800. Player is at about (600, 405)? The WAVE 1 text at y~310. Health bar at y~100. Bottom controls at y~700. So player at ~520? Hard to tell. Let me just perform interactions and inspect.

Let me click-hold to fire rightward and move. I'll first do a key press for movement and then screenshot. Actually the browser tool has drag to hold mouse? click does a click. Let me use drag from player to right to simulate hold + aim.

Let me do a drag from (600,400) to (900,400) to fire right. Then screenshot.

Actually to test firing I could click and hold via drag. Let me try.

Firing works — bullets travel right toward the pointer. The player rotated to face pointer (0 rad, pointing right). Good.

Aliens advance toward player? They haven't moved much in this frame perhaps. Let me test movement with keys and hitting an alien. Let me aim at an alien and fire. But the browser tool doesn't support key hold easily? It supports action "key". Let me test pressing 'd' a few times.

Let me instead verify alien advancement and a hit. I'll aim toward the bottom-left alien and fire. But timing — bullets travel. Let me instead just wait a moment and screenshot to see aliens closer. The motion action can capture.

Let me test a hit by aiming at the alien up top right: drag from player to it. But player rotation aims there, fire, bullets travel. Let me do multiple drags.

Actually easier: use the inspect to check state via window.game? The browser inspect returns DOM, not JS eval. Hmm.

Let me do a drag toward the top-right alien and then screenshot after a moment.

Score is now 10 — a bullet hit and killed an alien. Health dropped to 88, so an alien contacted the player (contact damage works). Aliens advanced toward player (they're now around the player). Bullets travel toward pointer (up-right). 

Now let me test movement. Use key action to press 'd' and 'w'. Also verify game over / restart. Given time, let me test movement quickly.

Let me press 'd' several times. The key action may need keydown then keyup; I'll try.

Health is dropping from contact (76/100). Movement via key seems not to persist because keydown/keyup likely immediate. Hard to verify exactly, but the implementation is straightforward and matches spec.

I want to verify game over and restart. Let me let the player take damage by not moving — wait, aliens are being killed? There are still 2 aliens left. Let me just wait and let them hit the player repeatedly. Since contact destroys the alien, only 2 more hits available = 24 damage, dropping to 52. Not enough for game over.

To test game over I'd need to survive to be hit by many aliens. Let me just fire less and wait through waves. That takes time. Alternatively I can trust the code. But the requirement says test game-over state. Let me force it via some means — I can't eval JS with these tools directly. Hmm.

Actually the browser inspect might return the DOM only. I could add a temporary test hook, but time. Let me think: I can use the "key" action? No.

Maybe I can trigger game over by waiting. There are 2 aliens now, each does 12 damage. Health 76 -> 52. Then wave 2 comes with more aliens. If I don't fire, I'll take hits every 700ms. Wave 2 has 7 aliens, enough to kill. But this could take ~20-30 seconds and they need to reach the player. Let me just wait and screenshot after some time. The motion action might advance frames. Let me use motion.

Actually, let me reduce effort: I'll temporarily change CONTACT_DAMAGE / add a debug? No, better to just test the game over by letting it play. Let me use motion to run frames.

Actually there's a simpler approach: I can reload and immediately not shoot; aliens converge on player. In ~10-15 seconds with 5 aliens all contacting, 5*12=60 damage, but invuln 700ms means over ~3.5s min. They spawn from edges and travel maybe 3s. So in ~8s, 5 hits = 60. Not death from full. Then wave 2 with 7 aliens: another 84 -> death. Total maybe 20s. Fine.

Let me use motion to capture frames and wait. Let me first reload to start clean and don't fire.

Actually to speed up, I could increase CONTACT_DAMAGE for testing then revert. But simpler: let me just wait using motion with a few calls. Let me reload, then motion over time.

Let me do reload and then motion.

Fresh state: Health 100/100, Score 0, Wave 1. Good. Controls displayed.

Now let me wait for game over. Let me use motion action maybe. I'll just call motion (screenshot over motion frames) after some waiting. The tool call itself may take a moment. Let me call motion.

The motion frames show aliens slowly advancing but not reaching player yet in ~2.3s. Aliens at bottom are moving up. Health still 100. They're slow-ish (speed ~64 for wave1). They'll take maybe 5s to reach. Let me wait longer. But the tool's motion only ran 2.3s. Let me call motion again, maybe it runs longer based on frames. Let me instead test game over more directly by reducing time. Actually, 5 aliens * 12 = 60 damage, so health would reach 40 after wave 1 clears (aliens destroyed on contact, wave cleared -> wave 2). Then wave 2 with 7 aliens -> 84 more, so death. Should happen by ~wave 2. Let me just run motion a few more times.

Actually, I realize the aliens during motion are barely moving — bottom pair moved from y~660 to y~590 over 2.3s in an 800px display => canvas distance ~70px/1.25=56px over 2.3s = 24px/s? That's less than speed 64. Hmm maybe because Phaser's game loop is throttled when not focused, or the frame time. Whatever. They do advance.

Let me keep running motion to let the game progress to game over. I'll call motion twice more.

Contact works: health dropped 100 -> 88 -> 76 as aliens reach player. Good.

Now I need to verify game over and restart. This will take a while naturally. Let me speed up testing by temporarily lowering player HP via a debug query param? I could add a URL hash to set hp? But no requirement. Alternatively I can add a hidden debug key for testing then remove. But the artifact should be clean.

Better: I'll just run motion several more times. Wave 1 has 5 aliens; 3 have hit (health 76), 2 left. After those, wave cleared -> wave 2 (7 aliens). Each hits 12. 76 -> after 2 more = 52 -> wave 2 -> 7 hits -> 52-84 = dead around 5th hit. So total remaining hits ~7. At ~1 hit per ~1.5s of motion perhaps. Let me run motion a few more times. But the frames may be limited.

Actually a cleaner test: temporarily modify DAMAGE_COOLDOWN to 0 and CONTACT_DAMAGE high, test game over, then revert. But then I'd need to re-test. Given budget, let me instead trust and just run more motion.

Let me run motion 3 more times.

Wave cleared works, score got bonus (0 -> 25), health 40/100, wave 2 started with more aliens (7 visible). Great. Now health 40, wave 2. 4 hits needed to die. Let me run motion again to reach game over.

Game over works, gameplay stopped, shows final score and wave, Restart button.

Now test Restart button. The button is at display ~(600,495) in 1200x800. Click it.

Restart works: health 100/100, score 0, wave 1. The player is alive. 

Everything verified. One minor thing: the player rotation at reset points down (the ship appears pointing down) because the pointer was previously at the button location below. That's fine.

All required behavior checked:
- controls displayed ✓
- movement — not fully verified via key hold, but the code is standard. Let me quickly verify movement with the key tool. The key action sends a key event; whether it holds is unclear. Let me check if there's a way. The "type" action types text. Keys via "key". Earlier pressing d didn't obviously move the player. But that might be because keydown+keyup happened within a frame, so no movement. That's expected. I'll note movement as implemented but not fully verified through automation.

Actually I could verify by holding: there's no hold key action. The drag holds mouse. N/A. I'll report movement unverified by automation but logic is standard.

Let me double check the file is present and no issues. It is fine. 

One more consideration: requirement "Aim toward the mouse pointer" — verified rotation changed. Good.

Let me make sure file saved. Yes.

I'm done. Let me give a brief report.
