Week04,HW04

在課堂上製作屬於自己的小畫家，我的小畫家具有變換顏色和變換粗細的功能，這樣大家上課就能玩圈圈叉叉囉!

執行圖:

程式碼:


void setup(){
  size(600,600);
  fill(255,0,0);
  rect(0,0,50,50);//紅按鈕
  fill(0,255,0);
  rect(0,50,50,50);//綠按鈕
  fill(0,0,255);
  rect(0,100,50,50);//藍按鈕
  fill(0,0,0);
  rect(0,150,50,50);//黑按鈕
  fill(255,255,255);
  rect(550,0,50,50);//粗按鈕
  rect(550,50,50,50);//細按鈕
  fill(0,0,0);
  ellipse(575,25,40,40);//粗圓
  ellipse(575,75,10,10);//細圓
}
int lines=2;
void draw(){
  if     (mousePressed && mouseX<50 && mouseY<50)  stroke(255,0,0);
  else if(mousePressed && mouseX<50 && mouseY<100) stroke(0,255,0);
  else if(mousePressed && mouseX<50 && mouseY<150) stroke(0,0,255);
  else if(mousePressed && mouseX<50 && mouseY<200) stroke(0,0,0);
 
  else if(mousePressed && mouseX>550 && mouseY<50){
    strokeWeight(++lines);
  }
  else if(mousePressed && mouseX>550 && mouseY<100){
    strokeWeight(--lines);
    if(lines<2)lines=2;
  }
  else if(mousePressed)  line(mouseX, mouseY, pmouseX, pmouseY);
}
