3-1 跟著滑鼠移動

void setup(){
  size(600,600);
  background(100,100,100,100);
}

void draw(){
  fill(255,255,0);
  triangle(mouseX,100,mouseX,150,100,mouseY);
  fill(150,20,100);
  ellipse(mouseX,mouseY,100,100);
  fill(255,255,255);
  rect(mouseX,mouseY,100,100);
}

3-2 追著滑鼠移動

void setup(){
  size(600,600);
  background(100,100,100,100);
}

float x=100,y=100,x1=150,y1=150,x2=200,y2=200;
void draw(){
  background(0,150,255,100);
  fill(0,255,255);
  ellipse(x,y,100,100);
  triangle(x,y,mouseX,mouseY,mouseX,mouseY);
  fill(255,100,100);
  ellipse(mouseX,mouseY,30,30);

  fill(255,255,0);
  ellipse(x1,y1,100,100);
  triangle(x1,y1,mouseX,mouseY,mouseX,mouseY);

  fill(0,255,0);
  ellipse(x2,y2,100,100);
  triangle(x2,y2,mouseX,mouseY,mouseX,mouseY);

  x=x*0.9+mouseX*0.1;  //x=(x+mouseX)/2;
  y=y*0.9+mouseY*0.1;  //y=(y+mouseY)/2;
  x1=x1*0.5+mouseX*0.3;
  y1=y1*0.5+mouseY*0.3;
  x2=x2*0.3+mouseX*0.1;
  y2=y2*0.3+mouseY*0.1;
}

今天教的隨滑鼠移動很有趣，謝謝老師。
