i have base game class , enemy class. when instantiate enemy using base game integer increase , when 1 dies need decrease integer. the end result being new enemy spawns every few seconds long integer less max_enemies any way i'm clue less , hoping direct me how should arrange ( have enemies increase number when spawn? ) here's basic idea: use factory method. may want handle of specifics differently. void main() { var game = new game(); game.createenemy("blinky"); console.writeline(game.enemycount); game.createenemy("clyde"); console.writeline(game.enemycount); game.destroyenemy(game.enemies[0]); console.writeline(game.enemycount); } public class game { public list<enemy> enemies = new list<enemy>(); public void createenemy(string name) { if (enemycount >= max_enemies) return; var enemy = new enemy { name = name}; enemies.add(enemy); } public void ...

i have created crystal report populated view. have 4 parameters. want able filter 1 parameter @ a time. parameters studio, division, supervisor, date. need able filter parameter alone. so, if filter studio need data studio no matter division, supervisor or date are. need able 4 parameters. any appreciated. using version 14.1.6.1702 i figured out. 4 parameters pop @ same time when report opened. user has choose 1 wants filter , other 3 parameters user adds values. accomplishes needed. to filter single division: area - choose values studio - choose values division - choose 'east' division date - choose values this result in areas, studios, , dates correspond east division.

please me out separate these actionlisteners in periodic table attempting complete. when execute program , click on 'h', opens other elements , when others clicked, not work. need way separate these using method... import javax.swing.*; import java.awt.*; import java.awt.event.*; public class periodictable { public static void main (string[] args) { jframe frame = new jframe("elements"); frame.setvisible(true); frame.setsize(1000,1500); frame.setdefaultcloseoperation(jframe.exit_on_close); jpanel panel = new jpanel(); frame.add(panel); jbutton button1 = new jbutton("h"); panel.add(button1); button1.addactionlistener (new action1()); jbutton button2 = new jbutton("he"); panel.add(button2); button2.addactionlistener (new action2()); jbutton button3 = new jbutton("li"); panel.add(button3); button3.addactionlistener (new action2()); } static class action1 implements actionlistener { public void ...

i have data frame initial of following format > head(initial) strings 1 a,a,b,c 2 a,b,c 3 a,a,a,a,a,b 4 a,a,b,c 5 a,b,c 6 a,a,a,a,a,b and data frame want final > head(final) strings b c 1 a,a,b,c 2 1 1 2 a,b,c 1 1 1 3 a,a,a,a,a,b 5 1 0 4 a,a,b,c 2 1 1 5 a,b,c 1 1 1 6 a,a,a,a,a,b 5 1 0 to generate data frames following codes can used keep number of rows high initial<-data.frame(strings=rep(c("a,a,b,c","a,b,c","a,a,a,a,a,b"),100)) final<-data.frame(strings=rep(c("a,a,b,c","a,b,c","a,a,a,a,a,b"),100),a=rep(c(2,1,5),100),b=rep(c(1,1,1),100),c=rep(c(1,1,0),100)) what fastest way can achieve this? appreciated we can use base r methods task. split 'strings' column ( strsplit(...) ), set names of output list sequence of rows, stack convert data.frame key/value columns, frequency table , convert 'data.frame' , cbind origi...
