Thread fors�tter i C++

Tue, 17 Mar 2015 16:39:57 GMT

godaften folkens.

sad og rodede med noget combat sjov i C++ og faldt over en "ikke hensigtsm�ssig fejl"

main

C++ kode

 #include <iostream>
 #include <thread>
 #include <conio.h>
 #include <mutex>
 #include <string>
 #include "Player.h"
 
 using namespace std;
 
 
 mutex mux1;
 
 void dueler(Player &player, Player &enemy)
 {
     do
     {
 
         _sleep(player.get_as());
         mux1.lock();
         cout << player.get_name()<< " hit " << enemy.get_name() << " for " << player.get_str() << " damage!" << endl;
         enemy.dmg(player.get_str());
         mux1.unlock();
 
     } while ((enemy.ask_dead() != true) && (player.ask_dead() != true));
 
 
 
 }
 
 
 
 
 
 int main()
 {
 
     Player Player1("kasper", 100, 5, 200);
     Player Player2("Bagger", 150, 8, 3000);
 
     thread dueler1(dueler,Player1,Player2);
     thread dueler2(dueler, Player2, Player1);
 
 
     dueler1.join();
     dueler2.join();
 
 
 
 
 
 
 }

Player.h

C++ kode

 #include <iostream>
 #include <string>
 
 using namespace std;
 
 class Player
 {
 public:
     Player(string name_, int maxhp_, int strenght_, int attackspeed_)
     {
         name = name_;
         maxhp = maxhp_;
         hp = maxhp;
         strenght = strenght_;
         attackspeed = attackspeed_;
         isdead = false;
     }
     void fullhp()
     {
         hp = maxhp;
     }
 
     void dmg(int dmg)
     {
         hp -= dmg;
         if (hp < 0)
             dead();
     }
 
     void dead()
     {
         isdead = true;
         cout << name <<" died like a pessant";
         
         
         
     }
 
     string get_name()
     {
         return name;
     }
     int get_hp()
     {
         return hp;
     }
     int get_maxhp()
     {
         return maxhp;
     }
     int get_str()
     {
         return strenght;
     }
     int get_as()
     {
         return attackspeed;
     }
     bool ask_dead()
     {
         return isdead;
     }
 
 
 private:
     string name;
     int maxhp;
     int hp;
     int strenght;
     int attackspeed;
     bool isdead;
 
 
 };

problemet ligger umiddelbart i

C++ kode

 void dueler(Player &player, Player &enemy)
 {
     do
     {
 
         _sleep(player.get_as());
         mux1.lock();
         cout << player.get_name()<< " hit " << enemy.get_name() << " for " << player.get_str() << " damage!" << endl;
         enemy.dmg(player.get_str());
         mux1.unlock();
 
     } while ((enemy.ask_dead() != true) && (player.ask_dead() != true));
 
 
 
 }

n�r den ene spiller dr�ber den anden afsluttes den tr�d korrekt, men den anden tr�d forts�tter med at angribe selvom han selv er d�d? det er sikkert simpelt, men tror jeg har stirret mig blind p� det, og ville derfor h�rer om der m�ske var nogle af jer der kunne finde fejlen

hold thread i live

Hej udviklere,

er det muligt at holde en thread i live efter at den har udf�rt sin kode?

P� forh�nd tak!

Lidt hj�lp til java, og Threading

Hej Udviklere,

Jeg har siddet, og rodet lidt med et problem. Dette problem omhandler, at i programmet, har jeg 2 dele. En visuel del og en beregnings del, og jeg ville gerne have, at de k�re p� en s�dan m�de, s� n�r beregnings delen har beregnet en del, s� bliver visualiseringen opdateret. Indtil videre er det design, der er lagt ind i det p� f�lgende m�de:

Beregnings delen startes
K�re en beregning og sender beregningen til en Observer
Denne Observer, sender det s� direkte videre til vores visualiserings del.

Koden for den del, hvor beregnings delen startes er her:

H�ber at I har nogle id�er til, hvordan man kan opn� den �nskede funktionalitet.
