week09

作業0:複習上周的程式，上周最後一個程式作業

作業1:

PShape body,head;

void setup(){

  size(400,400,P3D);

  body =loadShape("body.obj");

  head = loadShape("head.obj");

}

void draw(){

  translate(200,300);

  sphere(10); //球當原點

  scale(10,-10.10); //上下反過來

  shape(body,0,0);

  shape(head,0,0);

}

作業2:讓上週程式變更簡單

//week09_2_guamdan_head_body_push_trt_pop

PShape body,head;

void setup(){

  size(400,400,P3D);

  body =loadShape("body.obj");

  head = loadShape("head.obj");

}

void draw(){

  background(204);

  translate(200,300);

  sphere(10); //球當原點

  scale(10,-10.10); //上下反過來

  shape(body,0,0);

  pushMatrix();

    translate(0,22,5);

    //rotate(radians(mouseX-200));

    rotateY(radians(mouseX-200));

    //rotateX(radians(mouseY-60));

    translate(0,-22,5);

    shape(head,0,0);

  popMatrix();

}

作業3:改移下讓他變成手臂和上手臂

//week09-3_gumdan_uparm_upuparm_push_trt_pop

PShape uparm1,upuparm1;

void setup(){

  size(400,400,P3D);

  uparm1=loadShape("uparm1.obj");

  upuparm1=loadShape("upuparm1.obj");

}

void draw(){

  background(204);

  translate(200,300);

  sphere(3);

  

  scale(10,-10,10);

  

  shape(upuparm1,0,0);//上上手臂

  pushMatrix();

    translate(4.1,19.9);

    rotateX(radians(mouseY));

    translate(-4.1,-19.9);

    //translate(mouseX/10.0,-mouseY/10.0);

    //println(mouseX/10.0,-mouseY/10.0);

    shape(uparm1,0,0);

  popMatrix();

}

作業4:把手臂掛回去，讓他變成可以自由行動的手臂

//week09-4_gumdan_uparm_upuparm_hand_push_trt_pop

PShape uparm1,upuparm1,hand1;

void setup(){

  size(400,400,P3D);

  uparm1=loadShape("uparm1.obj");

  upuparm1=loadShape("upuparm1.obj");

  hand1=loadShape("hand1.obj");

}

void draw(){

  background(204);

  translate(200,300);

  sphere(3);

  

  scale(10,-10,10);

  

  shape(upuparm1,0,0);

  pushMatrix();

    translate(-4.1,19.9);

    rotateZ(radians(mouseX));

    translate(4.1,-19.9);

    shape(uparm1,0,0);

    pushMatrix();

    translate(-4.5,16.9);

    rotateX(radians(mouseY));

    translate(4.5,-16.9);

      //translate(mouseX/10.0,-mouseY/10.0); //一邊一移動，一邊印出數值

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

      shape(hand1,0,0);

    popMatrix();

  popMatrix();

}

作業5:我們想要讓他結合鍵盤，按下"1"時轉上臂，"2"時轉下面手臂

//week09-5_gumdan_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];

int ID=0;

void keyPressed(){

  if(key=='1') ID =1;

  if(key=='2') ID =2;

}

void mouseDragged(){

  angle[ID] += mouseX-pmouseX;

}

void draw(){

  background(204);

  translate(200,300);

  sphere(3);

  

  scale(10,-10,10);

  

  shape(upuparm1,0,0);

  pushMatrix();

    translate(-4.1,19.9);

    rotateZ(radians(angle[1]));

    translate(4.1,-19.9);

    shape(uparm1,0,0);

    pushMatrix();

    translate(-4.5,16.9);

    rotateX(radians(angle[2]));

    translate(4.5,-16.9);

      //translate(mouseX/10.0,-mouseY/10.0); //一邊一移動，一邊印出數值

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

      shape(hand1,0,0);

    popMatrix();

  popMatrix();

}

ဝ

作業6:

//week09-6_save_saveString_loadStrings

void setup(){

    size(300,300);

    rect(10,10,80,80);

    rect(110,110,80,80);

    save("file.png");//把畫面存檔

    another=loadStrings("lines.txt");

}

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);//print(now);//小黑印出來

}

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

String [] another;//另外一個讀到字串的資烙結構

void keyPressed(){

  String [] arr=new String[lines.size()];//傳統的java陣列資料結構

  lines.toArray(arr);//把ArrayList轉換成傳統的陣列，以便存檔

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

}

作業7:
