week14_寶欸學習筆記

1.小畫家傳數字
client

import processing.net.*;
Client client;
void setup(){
  size(300,300);
  client=new Client(this,"127.0.0.1",7777);
}
void draw(){
  if(mousePressed){
    line(mouseX,mouseY,pmouseX,pmouseY);
    client.write(mouseX+" "+mouseY+" "+pmouseX+" "+pmouseY+"\n");
  }
}

server

import processing.net.*;
Server server=null;
Client client=null;
void setup(){
  size(300,300);
  server=new Server(this,7777);
}
void draw(){
  Client temp = server.available();
  if(temp!=null){
    client=temp;
  }
  if(client!=null){
    String now = client.readString();
    if(now!=null) print(now);
  }
}

server視窗要放前面!!!!

2.小畫家畫線

client

import processing.net.*;
Client client;
void setup(){
  size(300,300);
  client=new Client(this,"127.0.0.1",7777);
}
void draw(){
  if(mousePressed){
    line(mouseX,mouseY,pmouseX,pmouseY);
    client.write(mouseX+" "+mouseY+" "+pmouseX+" "+pmouseY+"\n");
  }
}

server

import processing.net.*;
Server server=null;
Client client=null;
void setup(){
  size(300,300);
  server=new Server(this,7777);
}
void draw(){
  Client temp = server.available();
  if(temp!=null){
    client=temp;
  }
  if(client!=null){
    String now = client.readString();
    if(now!=null){
      String []xyxy=splitTokens(now);
      line(int(xyxy[0]),int(xyxy[1]),int(xyxy[2]),int(xyxy[3]));
    }
  }
}

3.按左鍵畫圖案右鍵消失

import processing.net.*;
ArrayList<PVector>points;
Client client;
void setup(){
  size(300,300);
  client=new Client(this,"127.0.0.1",7777);
  points=new ArrayList<PVector>();
}
void draw(){
  background(255);
  for(int i=0;i<points.size();i++){
    ellipse(points.get(i).x,points.get(i).y,5,5);
  }
  
}
void mouseDragged(){
  if(mouseButton==LEFT) points.add(new PVector(mouseX,mouseY));
  if(mouseButton==RIGHT && points.size()>0) points.remove(points.size()-1);
}
