week04-卓佾柔的上課筆記

一、射擊遊戲

1.陣列宣告(畫圖)

float [][]pigx=new float[5][4];
float [][]pigy=new float[5][4];
boolean [][]pigAlive=new boolean[5][4];
void setup(){
   size(800,600);
   for(int i=0;i<5;i++){
     for(int j=0;j<4;j++){
       pigx[i][j]=700-i*100; pigy[i][j]=100+j*100; pigAlive[i][j]=true;
     }
   }
}
void draw(){
   for(int i=0;i<5;i++){
     for(int j=0;j<4;j++){
        fill(#07DE0F); ellipse(pigx[i][j],pigy[i][j],100,100); //上色
     }
   }
   fill(#DE0719); ellipse(400,300,100,100); //上色
}

2.碰到怪物後怪物消失

寫好牛頓第一運動定律和牛頓第二運動定律。然後讓pig 碰到 bird時, 給它死。沒死的才畫出來

float birdX=100,birdY=400;

float birdVX=0,birdVY=0;

float birdAX=0,birdAY=0;

float [][]pigx=new float[5][4];

float [][]pigy=new float[5][4];

boolean [][]pigAlive=new boolean[5][4];

void setup(){

   size(800,600);

   for(int i=0;i<5;i++){

     for(int j=0;j<4;j++){

       pigx[i][j]=700-i*100; pigy[i][j]=100+j*100; pigAlive[i][j]=true;

     }

   }

}

void draw(){

  background(255); //背景顏色

   for(int i=0;i<5;i++){

     for(int j=0;j<4;j++){

       if( dist(birdX,birdY,pigx[i][j],pigy[i][j])<100) pigAlive[i][j]=false;

        //fill(#07DE0F); ellipse(pigx[i][j],pigy[i][j],100,100);

        if(pigAlive[i][j]) {fill(#07DE0F); ellipse(pigx[i][j],pigy[i][j],100,100);}

     }

   }

   //fill(#DE0719); ellipse(400,300,100,100);

   fill(#DE0719); ellipse(birdX,birdY,100,100);//draw the angry bird

   

   birdX+=birdVX;birdY+=birdVY;//update the angry bird

   birdVX+=birdAX;birdVY+=birdAY;

}

void mouseDragged(){

  birdX=mouseX;birdY=mouseY;

}

3.發射子彈

做出 (1) 直線運動, (2) 拋物線

float birdX=100,birdY=400;
float birdVX=0,birdVY=0;
float birdAX=0,birdAY=0;
float [][]pigx=new float[5][4];
float [][]pigy=new float[5][4];
boolean [][]pigAlive=new boolean[5][4];
void setup(){
   size(800,600);
   for(int i=0;i<5;i++){
     for(int j=0;j<4;j++){
       pigx[i][j]=700-i*100; pigy[i][j]=100+j*100; pigAlive[i][j]=true;
     }
   }
}
void draw(){
  background(255);
   for(int i=0;i<5;i++){
     for(int j=0;j<4;j++){
       if( dist(birdX,birdY,pigx[i][j],pigy[i][j])<100) pigAlive[i][j]=false;
        //fill(#07DE0F); ellipse(pigx[i][j],pigy[i][j],100,100);
        if(pigAlive[i][j]) {fill(#07DE0F); ellipse(pigx[i][j],pigy[i][j],100,100);}
     }
   }
   //fill(#DE0719); ellipse(400,300,100,100);
   fill(#DE0719); ellipse(birdX,birdY,100,100);//draw the angry bird
 
   birdX+=birdVX;birdY+=birdVY;//update the angry bird
   birdVX+=birdAX;birdVY+=birdAY;
}
void mouseDragged(){
  birdX=mouseX;birdY=mouseY;
  birdVX=0;birdVY=0;
}
void mouseReleased(){
  //birdVX=(100-mouseX)/20.0; birdVY=(400-mouseY)/20.0; //線性運動
  birdVX=(100-mouseX)/5.0; birdVY=(400-mouseY)/5.0; birdAY=0.98; //拋物線
}

4.忘了清 birdAY 加速度,可能會造成 自由落體, 所以 mouseDragged時要清空birdAY

float birdX=100,birdY=400;
float birdVX=0,birdVY=0;
float birdAX=0,birdAY=0;
float [][]pigx=new float[5][4];
float [][]pigy=new float[5][4];
boolean [][]pigAlive=new boolean[5][4];
void setup(){
   size(800,600);
   for(int i=0;i<5;i++){
     for(int j=0;j<4;j++){
       pigx[i][j]=700-i*100; pigy[i][j]=100+j*100; pigAlive[i][j]=true;
     }
   }
}
void draw(){
  background(255);
   for(int i=0;i<5;i++){
     for(int j=0;j<4;j++){
       if( dist(birdX,birdY,pigx[i][j],pigy[i][j])<100) pigAlive[i][j]=false;
        //fill(#07DE0F); ellipse(pigx[i][j],pigy[i][j],100,100);
        if(pigAlive[i][j]) {fill(#07DE0F); ellipse(pigx[i][j],pigy[i][j],100,100);}
     }
   }
   //fill(#DE0719); ellipse(400,300,100,100);
   fill(#DE0719); ellipse(birdX,birdY,100,100);//draw the angry bird
 
   birdX+=birdVX;birdY+=birdVY;//update the angry bird
   birdVX+=birdAX;birdVY+=birdAY;
}
void mouseDragged(){
  birdX=mouseX;birdY=mouseY;
  birdVX=0;birdVY=0;
  birdAY=0;
}
void mouseReleased(){
  //birdVX=(100-mouseX)/20.0; birdVY=(400-mouseY)/20.0; //shi-hsien-yun-dong
  birdVX=(100-mouseX)/5.0; birdVY=(400-mouseY)/5.0; birdAY=0.98; //pao-wu-hsien
}

二、放音樂

sound文件庫

import processing.sound.*;
SoundFile sound;
void setup(){
  size(800,600);
  sound=new SoundFile(this,"fish.mp3");
  sound.play();
  sound.loop();
}

minim文件庫

import ddf.minim.*;

Minim minim;
AudioPlayer player;

void setup(){
  size(800,600);
  minim=new Minim(this);
  player=minim.loadFile("fish.mp3",2048);
  player.play();
  //player.loop();
}
void draw(){

}
