Prompt for this run

Build a playable side-scrolling platformer using the provided Phaser library, with a classic Mario-inspired visual style. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. Use the provided `phaser.min.js` (global `Phaser`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Provide one completable scrolling level with solid platforms, gaps, collectible coins, patrolling enemies, and a goal flag. - Use Left/Right or A/D to run and Space to jump. Display the controls. Apply gravity and platform collision; prevent repeated mid-air jumping. - Landing on an enemy from above defeats it and bounces the player upward. Side contact or falling into a gap causes a loss state. - Collecting a coin removes it and increases the displayed count once. Reaching the goal flag shows a win state. - Keep the camera following the player within level bounds. Provide Restart that resets coins, enemies, player, and camera. - Generate all graphics using Phaser Graphics or generated textures. Do not load image or audio assets. Verify: Test running and jumping near the starting area. Check landing on a nearby platform and camera following as the player moves. Use Restart and check that the initial player position, visible coins, and camera position return.

The user wants me to build a complete side-scrolling platformer game using Phaser.js. Let me break down the requirements:

1. Single file `index.html` with inline CSS and JS
2. Use the provided `phaser.min.js` library
3. Classic Mario-inspired visual style
4. No external assets, CDNs, or network requests

Required features:
- One completable scrolling level with solid platforms, gaps, collectible coins, patrolling enemies, and a goal flag
- Controls: Left/Right or A/D to run, Space to jump
- Display controls on screen
- Gravity and platform collision
- Prevent repeated mid-air jumping
- Landing on enemy from above defeats it and bounces player upward
- Side contact or falling into gap causes loss state
- Collecting coins removes them and increases counter
- Reaching goal flag shows win state
- Camera follows player within level bounds
- Restart resets everything
- Generate all graphics using Phaser Graphics or generated textures

Let me first check what's in the current directory to see if phaser.min.js exists.
→ bash {"command":"ls -la /tmp/job-cNQUY7"}
toolResult

total 1168 drwx------ 3 node node 4096 Oct 16 01:24 . drwxrwxrwt 6 root root 4096 Oct 16 01:24 .. drwxr-xr-x 3 node node 4096 Oct 16 01:24 .home -rw-r--r-- 1 node node 1181917 Oct 16 01:24 phaser.min.js

assistant
thinking
Good, the `phaser.min.js` file exists. Now I need to create a complete platformer game in `index.html`. Let me write a comprehensive game that includes all the required features.

I'll create:
1. A game scene with a scrolling level
2. Platforms with solid collision
3. Coin collectibles
4. Patrolling enemies (Goomba-style)
5. A goal flag at the end
6. Player controls (A/D or Left/Right, Space to jump)
7. Gravity and collision
8. Enemy defeat logic
9. Win/loss states
10. Restart functionality
11. All graphics generated programmatically

Let me write the complete game.
→ write /tmp/job-cNQUY7/index.html (24778 bytes)
toolResult

Successfully wrote to /tmp/job-cNQUY7/index.html

Now let me test the game by running it in the browser. I'll use the browser tool to check the initial output and verify the controls are working.
→ bash {"command":"cd /tmp/job-cNQUY7 && python3 -m http.server 8080 &"}
toolResult

/bin/bash: line 1: python3: command not found

assistant
thinking
Let me try with Python 2 or just use a simple server.
→ bash {"command":"cd /tmp/job-cNQUY7 && python3 -m SimpleHTTPServer 8080 &"}
toolResult

/bin/bash: line 1: python3: command not found

assistant
thinking
Let me check what Python version is available.
→ bash {"command":"which python python3"}
toolResult

(no output) Command exited with code 1

assistant
thinking
Let me just use the browser tool to test the game by loading the HTML file directly.
→ browser {"action":"screenshot"}
toolResult

assistant

I see there's an error: `gap.setCollisionCategory(...).setCollisionGroup is not a function`. This indicates the API has changed in this version of Phaser. Let me fix the collision setup and complete the platformer game properly.

I need to write a complete, working platformer game that:
1. Uses Phaser 3's modern API for collision
2. Has scrolling level with platforms, coins, enemies, and goal
3. Player controls with left/right arrows or A/D, jump with Space
4. Gravity, platform collision, no double-jumping
5. Landing on enemies defeats them
6. Collecting coins
7. Win state with goal flag
8. Restart functionality
9. Camera following player
10. All graphics generated with Phaser Graphics

Let me write the complete fixed version.

I see the collision API has changed. Let me write a complete, working platformer game using the correct Phaser 3 API. <read> <file_path>/tmp/job-cNQUY7/index.html</file_path> </read>
