How to Style A Rect.js In P5.js?

In p5.js, you can style a rect.js by using the rect() function to draw a rectangle on the canvas and then modifying its properties such as fill color, stroke color, stroke weight, and corners.

To change the fill color of the rectangle, use the fill() function before calling rect(). You can pass in a color value such as a hexadecimal code, RGB value, or color name.

To change the stroke color of the rectangle, use the stroke() function before calling rect(). You can also set the stroke color to transparent by passing in noStroke().

To change the stroke weight of the rectangle, use the strokeWeight() function before calling rect(). Pass in a numerical value to set the thickness of the rectangle's stroke.

To change the corners of the rectangle, use the rectMode() function before calling rect(). You can set the corners to square by passing in CORNER, or rounded by passing in RADIUS.

By using these styling techniques, you can customize the appearance of rectangles in p5.js to match your design preferences.

function setup() {
  createCanvas(400, 400);
}

function draw() {
  background(220);
  
  // Set the style for the border
  stroke(0); // Set border color
  strokeWeight(2); // Set border thickness
  strokeCap(ROUND); // Set border cap style
  
  // Set the pattern for the dashes
  strokeDash([5, 10]); // Set dash pattern
  
  // Draw the dashed border for the rect
  rect(50, 50, 300, 300);
}

In the above code, the strokeDash() function is used to set the pattern of dashes for the border. The strokeDash() function takes an array of numbers as an argument, where each pair of numbers represents the length of a dash and the length of a gap between dashes. In this example, [5, 10] sets a pattern of a 5-pixel dash followed by a 10-pixel gap.

You can customize the dash and gap lengths according to your preferences by changing the values in the array passed to the strokeDash() function.
