羅浩倫的學習筆記 Week09

本週學習重點

1.上週Texture 貼圖 詳解

2.多重貼圖

3.Bump Mapping

上課紀錄

到moodle上課軟體下載Processing 3 執行範例程式碼

(https://www.openprocessing.org/sketch/249457)

接下來練習用Processing這個程式語言來讀圖檔

找一張自己喜歡的圖片，把它拉到Processing 3的視窗裡面新增程式的data

接下來只需要三行的程式碼

PImage img = loadImage("doraemon.png");

size(600,600);

image(img, 0,0, 600,600);

就可以成功讀出圖檔囉

接下來進階一點把程式碼包在函式裡面，然後讓電腦跟著滑鼠座標畫圖

就可以做出可以互動的程式了

最後練習一個的Mario的Processing 3程式

PImage imgMario, imgMarioJump, imgBrick;

double marioX=200, marioY=100;

double marioVX=0, marioVY=0;

boolean marioOnFloor = false;

int [][]map = {{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},

               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},

               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},

               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},

               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},

               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},

               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},

               {0,0,0,0,0,0,0,0,0,1,1,1,1,1,0,0},

               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},

               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},

               {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},

               {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1}};

void setup(){

  size(800,600);

  imgMario = loadImage("mario.jpg");

  imgMarioJump = loadImage("mariojump.png");

  imgBrick = loadImage("brick.png");

}

void draw(){

  background(255);

  if (map[(int)(marioY/50)][(int)(marioX/50)] != 0){

    marioOnFloor = true;

  }

  if (marioOnFloor == false){

    marioVY += 0.98;

  }

  else if (marioOnFloor == true){

    marioVY = 0;

  }  

  for (int x=0; x<16; x++){

    for (int y=0; y<12; y++){

      if (map[y][x] == 1)

        image(imgBrick, x*50, y*50, 50, 50);

    }

  }

  

  marioX += marioVX;

  marioY += marioVY;

  image(imgBrick, marioX, marioY, 50, 50);

  //image(imgMario, marioX, marioY, 100,100);

}

void keyPressed(){

  if (keyCode == UP)

      marioVY = -15;

  if (keyCode == LEFT)

      marioVX = -5;

  if (keyCode == RIGHT)

      marioVX = 5;

}

void keyReleased(){

  if (keyCode == LEFT || keyCode == RIGHT)

      marioVX = 0;

}
