逃離互動概論week01

 Week01

void setup(){

size(500,500);//視窗大小(寬,高);

background(255,255,0);

}

void draw(){

  ellipse(mouseX,mouseY,8,8);

}

void setup(){

size(500,500);//視窗大小(寬,高);

background(255);

}

void draw(){

  if(mousePressed) {

  line(mouseX,mouseY,pmouseX,pmouseY);

 }

}

新增顏色的選擇

void setup(){

size(500,500);//視窗大小(寬,高);

background(255);

}

void draw(){

  if(mousePressed) {

  line(mouseX,mouseY,pmouseX,pmouseY);

 }

}

void keyPressed(){

  if(key=='1') stroke(255,0,0);//紅

  if(key=='2') stroke(0,255,0);//綠

  if(key=='3') stroke(0,0,255);//藍

  }

if(key=='S'||key=='s') save("output.png");

}

新增粗細

  if(key=='+') strokeWeight(10);

  if(key=='-') strokeWeight(1);

改成可加減粗細

int w=1;

if(key=='+') strokeWeight(++w);

  if(key=='-') strokeWeight(--w);

  println(w);
