Processingでシンプルなものを作ってみた(第0001弾)

Last updated at Posted at 2022-12-02

ーーー シンプルな信号を描画してみた ーーー

小さい頃、ピコを使って信号の絵を描いていたことを思い出し、
Processingでやってみた。

工夫したところ
・ウィンドウサイズに応じて対応する
・図形描画に関しては自作関数を作成してその中にコードを書いた

(1) ウィンドウサイズ:640x480[px]

(2) ウィンドウサイズ:160x120[px]

int sizeH = 480;
int sizeW = sizeH * 4/3;

void settings()
{
  size(sizeW, sizeH);
}

void setup()
{
  background(255);
  noStroke();
}

void draw()
{
  translate(width / 4, height / 8);
  trafficLight();
}

void trafficLight()
{
  fill(0, 128, 255);
  rect(0, 0, height * 5/8, height * 5/24);
  
  fill(0, 192, 0);
  translate(height * 5/48, height * 5/48);
  circle(0, 0, height * 1/6);
  
  fill(255, 255, 0);
  translate(height * 5/24, 0);
  circle(0, 0, height * 1/6);
  
  fill(255, 0, 0);
  translate(height * 5/24, 0);
  circle(0, 0, height * 1/6);
  
  fill(0, 128, 255);
  translate(-height * 25/48, height * 5/48);
  rect(0, 0, height * 1/48, height * 5/8);
  
  fill(0, 128, 255);
  translate(0, 0);
  rect(0, 0, -height * 5/24, height * 5/12);
  
  fill(255, 0, 0);
  translate(0, 0);
  rect(-height * 1/48, height * 1/48, -height * 1/6, height * 1/6);
  
  fill(0, 192, 0);
  translate(0, height * 5/24);
  rect(-height * 1/48, height * 1/48,-height * 1/6, height * 1/6);
}
