Prompt for this run
Build an animated L-system tree using the provided p5.js library. 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 `p5.min.js` (global `p5`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Define an axiom, explicit production rules, and an angle for a branching L-system. Expand the grammar and interpret it to draw a connected trunk and branches; an unrelated random-line drawing is not sufficient. - Show progressive growth from the trunk toward branch tips. Once grown, the tree sways gently in the wind while child branches remain attached to their parents. - Provide a generation control from 1 to 5 and Regrow. Changing generation or pressing Regrow restarts growth using the same chosen grammar. - Bound grammar expansion and keep the whole tree visible at every supported generation. - Use procedural graphics. Choose branch styling, leaves, colors, and the particular branching grammar freely. Verify: Sample branch growth and inspect visible parent-child connections. Change the generation setting and check that growth restarts with a different branching structure. If growth has completed during inspection, sample the wind motion as well.

I'll create an animated L-system tree using the provided p5.js library. Here's the plan: 1. Set up the basic HTML structure with a canvas for drawing 2. Include the p5.js library 3. Define the L-system parameters and rules 4. Implement the tree growth and animation 5. Add controls for generation and regrowth Let's start by creating the index.html file with the basic structure and p5.js setup.
index.html (845 bytes)Successfully wrote to index.html
Now, I'll add the p5.js code to implement the L-system tree. This will include: 1. Setting up the L-system parameters 2. Defining the tree drawing functions 3. Implementing the animation and growth 4. Adding the controls for generation and regrowth Let's add this code to the index.html file.

Now, let's run the application in the browser to verify the functionality.

I can see that the application is running, but there's an error in the console. Let me inspect the console to get more details about the error.

The error in the console indicates that there is an "Invalid or unexpected token" in the JavaScript code. Let me inspect the code to find and fix the issue.

It seems the error is still present. Let me read the contents of the index.html file to inspect the code more closely.

I found a duplicate line and a syntax error in the `drawTree` function. Let me fix these issues.
