Thread: Text Game in C.

So I want to learn C and continue going up to higher level programming languages. I thought the best way to do this would be to start game development because it's very difficult and you know you know the language when you have a fully functional game. I'm starting off just doing a text game. Just to get the basics and the jist of it all. My question is am I coding the options and cases correctly. I'm not going to post the in depth text but here is the way I did it. If it helps you can input your own variables into the 1,2,3 spots.

Code:

#include <stdio.h>


void 1(){
     void 1(){
          }
     void 2(){
          }
     void 3(){
          }
         int input2;
         printf("Text");
         scanf("%d", &input2);
         switch(input2){
                       case 1:
                            11();
                            break;
                       case 2:
                            12();
                            break;
                       case 3:
                            13();
                            break;
                       }
         }
void 2(){
     printf( "Text");
     }
void 3(){
     printf( "Text");
     }
int main(){
    int input1;
    printf( "Text");
    scanf( "%d", &input1);
    switch(input1){
                  case 1:
                       1();
                       break;
                  case 2:
                       2();
                       break;
                  case 3:
                       3();
                       break;
                  case 4:
                       printf( "Text");
                       break;
                  default:
                          printf( "Text");
                          1();
                          break;
                  }
                  scanf("%d");
                  getchar();
    }

Start. Smaller.

Can you write a "Hello World" program that compiles and runs?

Well I'm already farther in than the "Hello World" program. I just wrote it in pseudocode because I'm a very paranoid person so I don't like to give any code. But seeing how it's hard to do it otherwise I guess I'll have to get over it. So here is the code.

Code:

#include <stdio.h>


void play(){
     void assaultrifle(){
          }
     void sniperrifle(){
          }
     void submachinegun(){
          }
         int input2;
         printf("Select your weapon\n");
         printf("1. Assault Rifle\n");
         printf("2. Sniper Rifle\n");
         printf("3. Sub-Machine Gun\n");
         printf("Enter selection number\n");
         scanf("%d", &input2);
         switch(input2){
                       case 1:
                            assaultrifle();
                            break;
                       case 2:
                            sniperrifle();
                            break;
                       case 3:
                            submachinegun();
                            break;
                       }
         }
void load(){
     printf( "Select which game save to load\n");
     }
void multiplayer(){
     printf( "Select multiplayer game type\n");
     }
int main(){
    int input1;
    printf( "1. Play Game\n");
    printf( "2. Load Game\n");
    printf( "3. Multiplayer\n");
    printf( "4. Exit\n");
    printf( "Enter selection number\n");
    scanf( "%d", &input1);
    switch(input1){
                  case 1:
                       play();
                       break;
                  case 2:
                       load();
                       break;
                  case 3:
                       multiplayer();
                       break;
                  case 4:
                       printf( "Goodbye\n");
                       break;
                  default:
                          printf( "Default selection...Play Game...\n");
                          play();
                          break;
                  }
                  scanf("%d");
                  getchar();
    }

I'm just wondering if I'm getting at it correctly...I know it compiles and runs fine, I just want to know if there is a more efficient way.

When I'm making a game, I have main() call a 1st menu, which is the most basic options, and a quit. That will (perhaps with other submenu's being called depending on the game), eventually reach a play1game() function. In play1game, there will be a large do while(game_Not_over && quit == 0) type loop. Everything to play one game will be handled inside that loop (which will typically call several other functions itself).

main() really isn't used for much in a well designed game, except calling the first outer menu, and returning an int to the operating system, imo.

I understand main() calling the 1st menu, but after that you lost me...could you give me an example in code? It would help out a lot more.

^ Something like this:

Code:

int main(void)
{
    int status;
   switch(main_menu())
   {
       case 1: status = play1game();break;
       //etc
   }
   return status;
}
......
int play1game()
{
     int quit_condition;
     int status;
     do
     {
      //game loop
     }while(!quit_condition);
     return status;
}

Where does main_menu come from in that?

In my example, it'd be a function that displays the choices, and returns the one selected by the user.
(But that was for you to figure out. :P)

So far this is what I've updated my game to, with the help of you guys.

Code:

#include <stdio.h>
#include <stdlib.h>
void Exit(){
     printf(" Now Closing\n ");
     }
void Multiplayer() {
     printf(" Loading Multiplayer Option\n ");
     }
void Load() {
     printf(" Load\n ");
     }
void Play() {
     printf(" Play\n ");
     }
void MainMenu() {
     int gameselectioninput;
     int playgame = 1;
     int loadgame = 2;
     int loadmultiplayeroption = 3;
     int exit = 4;
     printf("1. Play Game\n");
     printf("2. Load Game\n");
     printf("3. Load Multiplayer Option\n");
     printf("4. Exit\n");
     printf(" Enter Selection Number \n");
     scanf("%d", &gameselectioninput);
     if( gameselectioninput == playgame){
         Play();
         }
     else if ( gameselectioninput == loadgame){
          Load();
          }
     else if ( gameselectioninput == loadmultiplayeroption){
          Multiplayer();
          }
     else if ( gameselectioninput == exit){
          Exit();
          }
     }
int main(int argc, char *argv[])
{
    MainMenu();
    system("PAUSE");    
    return 0;
}
