畫出一條線



調整自體大小



新增一段程式碼:

//void Setup()//Unity use it
void setup(){
  size(800,600);
}
//void Update()//Unity use it
void draw(){
  if(mousePressed) background(255,0,0);
  else background(0,255,0);
}



滑鼠按下變成紅色



自製一個小畫家:

void setup(){
  size(800,600);
}
void draw(){
  if(mousePressed) line(mouseX,mouseY, pmouseX, pmouseY);
}



瞭解strokeWeight(畫筆粗細)

void setup(){
  size(800,600);
}
void draw(){
  if(mousePressed) line(mouseX,mouseY, pmouseX, pmouseY);
}
void keyPressed(){
  if(key=='1') strokeWeight(1);
  if(key=='2') strokeWeight(2);
  if(key=='3') strokeWeight(3);
  if(key=='9') strokeWeight(9);
}
