 week09_1首先 我們上課時先把上個禮拜的鋼蛋程式複習一遍

week09_2_gundam_head_body_push_trt_pop 

week02加上trt找到對應的數值 讓頭可以旋轉

week09_3_gundam_uparm_upuparm_push_trt_pop

week09_4_gundam_uparm_upuparm_hand_push_trt_pop

week09_5_gundam_uparm_upuparm_hand_keyboard_mouse_angle 這邊多加了關節用float[]來儲存多個關節

程式碼

//week09_5_gundam_uparm_upuparm_hand_keyboard_mouse_angle

PShape uparm1,upuparm1,hand1;

void setup(){

  size(400,400,P3D);

  uparm1 = loadShape("uparm1.obj");

  upuparm1 = loadShape("upuparm1.obj");

  hand1 = loadShape("hand1.obj");

}

float [] angle = new float[20]; //準備20個關節

int ID=0; //關節的代碼 之後會用angle[ID] 來改變值

void keyPressed(){

  if(key=='1') ID=1;

  if(key=='2') ID=2;

}

void mouseDragged(){

  angle[ID] += mouseX-pmouseX; //X方向的移動,可改變某個關節的角度

}

void draw(){

  background(204);

  translate(200,300);

  sphere(3); //小一點,比較清楚

  

  scale(10,-10,10);

  shape(upuparm1,0,0); //上上手臂

  pushMatrix();

    translate(-4.1,19.9); // 再掛回去原本的位置

    rotateZ(radians(angle[1]));

    translate(4.1,-19.9); //把物體的旋轉中心, 放到座標中心

    shape(uparm1,0,0); //上手臂

    pushMatrix();

      translate(-4.5,16.9);

      rotateX(radians(angle[2]));

      translate(4.5,-16.9);

      //translate(mouseX/10.0, -mouseY/10.0); //一邊移動、一邊找到數值

      //println(mouseX/10.0, -mouseY/10.0); //印出適合的數值 4.5,-16.9

      shape(hand1,0,0);

    popMatrix();

  popMatrix();

}

week09_6_save_saveStrings_loadStrings 

加上another 來load讀取 如果讀取到 就有陣列了 可以看到上一步動作所做出的移動

// week09_6_save_saveStrings_loadStrings

void setup(){

  size(300,300);

  rect(10,10,80,80);

  rect(110,110,80,80);

  save("file.png"); //這個範例,可把某個畫面 save() 存檔

  another = loadStrings("lines.txt"); // 如果順利讀到, 就有陣列了

}

int x=10,y=10,ID=0;

void draw(){

  background(204);

  if(another !=null){

    int[] now = int(split(another[ID], ' '));

    rect(now[0],now[1],80,80);

    ID = (ID+1) % another.length;

  }

  rect(x,y,80,80);

}

void mouseDragged(){

  x += mouseX-pmouseX;

  y += mouseY-pmouseY;

  String now = x + " " + y; // 現在座標的字串

  lines.add(now); //println(now); // 在小黑印出來

}

ArrayList<String> lines = new ArrayList<String>(); // ArrayList 資料結構

String [] another; // 另外一個讀到的字串的資料結構

void keyPressed(){

  String [] arr = new String[lines.size()];

  lines.toArray(arr);

  if(key=='s') saveStrings("lines.txt", arr); //按下英文小寫s會存檔

}
