Making a function and then calling it later is a fundamental part of programming. Let's create a simple example in your project to demonstrate this.\n\nWe'll create two functions:\n1. `drawLine` - to draw a line from one point to another.\n2. `clearCanvas` - to clear the canvas.\n\n### `script.js`\n```javascript\nlet drawingColor = 'black'; // Default drawing color\nlet brushSize = 5; // Default brush size\n\nfunction setup() {\n createCanvas(windowWidth, windowHeight); // Create a canvas that covers the entire window\n background(255);\n}\n\nfunction draw() {\n if (mouseIsPressed) {\n drawLine(pmouseX, pmouseY, mouseX, mouseY); // Call the drawLine function while the mouse is pressed\n }\n}\n\n// Function to draw a line\nfunction drawLine(x1, y1, x2, y2) {\n stroke(drawingColor); // Set the drawing color\n strokeWeight(brushSize); // Set the brush size\n line(x1, y1, x2, x2); // Draw a line from (x1, y1) to (x2, y2)\n}\n\n// Function to clear the canvas\nfunction clearCanvas() {\n background(255); // Set the canvas background to white, clearing it\n}\n```\n\n### Explanation:\n- **`drawLine` Function**: This function takes four parameters (`x1`, `y1`, `x2`, `y2`) to draw a line from point `(x1, y1)` to point `(x2, y2)`. This function is called inside the `draw` function when the mouse is pressed.\n- **`clearCanvas` Function**: This function clears the canvas by setting the background to white. It can be called whenever you want to clear the canvas.\n\nTo call the `clearCanvas` function, you could add a button to your HTML and set it up to call the function when clicked. \n\n### `index.html`\n```html\n\n\n\n\n \n \n Colorful Canvas Creations\n \n\n\n\n \n \n \n\n\n\n```\n\nBy clicking the \"Clear Canvas\" button, the `clearCanvas` function will be called, and the canvas will be cleared.\n\nWould you like to add this button and functionality to your project?","project_id":2143,"created_at":"2024-07-22T19:26:52.336404Z","output_tokens":null,"sender":"ai","code_id":122622,"deleted":0,"input_tokens":null,"id":60156},{"message":"How to make a function that doesn't run unless you tell it to","project_id":2143,"created_at":"2024-07-24T19:29:28.594579Z","output_tokens":null,"sender":"human","code_id":123762,"deleted":0,"input_tokens":null,"id":60579},{"message":"To create a function that doesn't run unless explicitly called, you simply define the function and then call it when needed.
