期末作品：射擊遊戲

今日複習
找到手的節點
不過設的數據太大了
所以位置怪怪的















程式碼：
import SimpleOpenNI.*;
SimpleOpenNI openni;
void setup(){
  size(600,400);
  openni = new SimpleOpenNI(this);
  openni.enableRGB();
  openni.enableDepth();
  openni.enableUser();
}
void draw(){
  openni.update();
  background(255);
  image(openni.userImage(),0,0,300,200);
  int [] userList = openni.getUsers();
  //for(int i=0;i<userList.length;i++)
  //    int userID = userList[i];
  PVector pos = new PVector(0,0,0);
  for(int userID : userList){//跟橘色螢光筆相同意思(畫面中有多少人就偵測多少人(最多六人))
    openni.getJointPositionSkeleton(userID,SimpleOpenNI.SKEL_LEFT_HAND,pos);//手的節點
  }
  ellipse(pos.x,pos.y,50,50);//畫點
  println(pos);
}
void onNewUser(SimpleOpenNI curContext,int userId){//若有其他人進入畫面則偵測
  openni.startTrackingSkeleton(userId);
}
