randomSeed() 是什麽意思？ 可以讓random flashing變規律？

• Combine with Visual Language Homework
• map() & constrain()
  • Role: map() re-scales input values from one range to another, while constrain() limits values within a strict range. Together, they enhance color contrast and prevent values from overflowing.
• colorMode(HSB)
  • Role: Changes the color space from RGB to HSB (Hue, Saturation, Brightness), preventing muddy intermediate gray tones during color blending.

Video Note:

let circle= {x:0, y:100, diameter:50}

ellipse(circle.x, circle.y, circle.diameter, circle.diameter);

Homework

1. Organize the example Zoog portrait into functions so that you can understand what it’s doing without right comments and you can easily turn different parts of the sketch on/off by commenting in/out calls to your functions.
