今天天氣晴12/12

這次教的程式碼

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");

  }

}

上面是服務端要先開這個。

下面是客戶端

import processing.net.*;

Server server=null;這邊是將Server或是Client先設為空值

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]));

       }

   }

}

運用連線將A畫，畫到B的地方，讓兩個有所連接

紅色的為連線程式碼。

第三個程式碼

import processing.net.*;

Client client;

ArrayList<PVector>points;

void setup(){

  size(300,300);

  client = new Client(this,"120.125.70.32",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));

  上面是畫出來。

  if(mouseButton==RIGHT)points.remove(points.size()-1);

  這邊是擦掉最後一個畫圖。

}

用P語言當小畫家然後若是畫錯可以消除。

下面的有點忘記先寫上來

import processing.net.*;

Server server=null;

Client client=null;

void setup(){

  size(300,300);

  server = new Server(this,7777);

}

void draw(){

  background(255);

   Client temp = server.available();

   if(temp !=null){

    client = temp; 

   }

   if(client !=null){

     String now=client.readString();

     if(now!=null) {

       String []xyxy = splitTokens(now);

       for(int i=0;i< xyxy.length;i+=4)

       line(int(xyxy[i+0]),int(xyxy[i+1]),int(xyxy[i+2]),int(xyxy[i+3]));

       }

   }

}
