2019-1-20 · void keyPressed(){ if(key == 'b' | key == 'B'){ color1 = color(random(255),random(255),random(255)); } else if(key == 'n' | key == 'N'){ color2 = color(random(255),random(255),random(255)); } } This changes color1 to a random color when you press B , or color2 when you press N .
stroke(random(100, 255), random(90, 255), random(100, 255)); makes for colors more bright (random starts at 100) Then in 10% of the cases - that’s what the if clause does - we choose a color almost red (with only a small amount of randomness)
Random Lines, Black Background processing fill()和stroke()函数 当参数的个数为一个的时候，颜色值为灰度值(gray value），两个参数时，非别为灰度值和透明值，3个参数时为 RGB 。fill还可以接收四个参数：file(R,G, B, alpha), alpha用来控制透明度的，255代表完全不透明，0代表完全透明，默认是不透明的，如下的例子可以说明这两个函数的 RGB color with ranges of 0 to 255 is not the only way you can handle color in Processing. Behind the scenes in the computer's memory, color is always talked about as a series of 24 bits (or 32 in the case of colors with an alpha). 図形の縁取り線のことをProcessingではストロークという。ストロークの色や太さを変更するにはstroke(color)とstrokeWeight(size)を使う。また、ストロークを消すには、noStroke()を使う。 [p5code]size(200, 200); // カラーモードをRGBの256段階に変更 colorMode(RGB, 256); Archived Sketch.

Title: Processing Cheatsheet Created Date: 5/6/2014 12:54:15 PM For each pixel, it creates a color based on that pixel’s distance from the three bouncing points, and then draws the pixel in that color. This creates a gradient that transitions through different colors as the points bounce around.

For example, if you run fill(204, 102, 0), all subsequent shapes will be filled with orange. This color is either specified in terms of the RGB or HSB color depending on the current colorMode(). (The default color space is RGB, with each value in the range from 0 to 255.) As colours are separated into red green and blue, you can create a new random colour by creating random primary colours: // Java 'Color' class takes 3 floats, from 0 to 1. float r = rand.nextFloat(); float g = rand.nextFloat(); float b = rand.nextFloat(); Then to finally create the colour, pass the primary colours into the constructor: x = 1 + int( random(6) ); // se comporta como un dado, de 1 a 6 El ordenador es incapaz de generar números realmente aleatorios, utiliza una tabla de números pseudo-aleatorios para ofrecernos resultados lo bastante aleatorios para la mayoría de los casos.
