      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

Guessing Game Problem

13 posts in this topic

[color=#000000][font=verdana, arial, helvetica, sans-serif][size=3]Hello, I tried making a guess my number game, but inverted, by having the user input a number and the computer trying to guess it.[/size][/font][/color]
[color=#000000][font=verdana, arial, helvetica, sans-serif][size=3]Here is the source code.[/size][/font][/color]

[code]
//Guess my Number (inverted)
//The computer will guess your number
#include <iosteam>
#include <cstdlib>
#include <ctime>
using namespace std;
int main ()
{
int myNumber,;
char yorn;
cout <<"Enter a number between 1 and 10: ";
cin >> myNumber;
cout <<"\nYou chose "<<myNumber <<" as your number."

do
{
srand(time(0));
int theNumber = rand() % 10 + 1;
cout <<"Is your number "<<theNumber<<"? (y/n)";
cin >> yorn;
} while (yorn == y);
cout <<"I won !";
return 0;
}
[/code]



[color=#000000][font=verdana, arial, helvetica, sans-serif][size=3]DevC++ says there is a problem in this part.[/size][/font][/color]

[color=#000000][font=verdana, arial, helvetica, sans-serif][size=3]cout <<"Enter a number between 1 and 10: ";[/size][/font][/color]

Thanks

What's the exact error message? It might not mean anything to you, but it probably means something to more experienced programmers, and we can help you understand it.

EDIT: What does your compiler think of [font=monospace]"<[/font]iosteam>" [sic]? You should generally only look at the first error message.

Why is there a comma after int mynumber? Also your loop will only run if the guess is right on the first shot. Shouldn't it be while yorn != y

Problem looks like it is here:
[code]int myNumber,;[/code]
Should not have a comma unless you are declaring multiple ints on that line.

You are also missing a semi-colon on this line:
[code]
cout <<"\nYou chose "<<myNumber <<"as your number."
[/code]

Also you should use an up-to-date IDE like MS Visual Studio Express or CodeBlocks.

It displays a lot of messages, but I believe its this one...
"iosteam: No such file or directory. "

it should be:
#include <iost[b]r[/b]eam>

also, move the srand to before the do .... while loop (you only want to call it once)

you need <iostream> not <iosteam>... also remove the above mentioned syntax error and you can adjust the loop according to how you want it.

EDIT** Just too slow! HAHA

Still giving me problems, here is what I have changed.

[code]
//Guess my Number (inverted)
//The computer will guess your number
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main ()
{
int myNumber;
char yorn;
cout <<"Enter a number between 1 and 10: ";
cin >> myNumber;
cout <<"\nYou chose "<<myNumber <<" as your number.";
srand(time(0));
do
{
int theNumber = rand() % 10 + 1;
cout <<"Is your number "<<theNumber<<"? (y/n)";
cin >> yorn;
} while (yorn != y);
cout <<"I won !";
return 0;
}[/code]

y is undefined. What you probably meant is 'y', which is the character y instead of the variable y.

Line: 20

Also keep in mind if you do (yorn != 'y') that will only check against the character y which is different from the character Y. If you want both you'd have to do ((yorn != 'y') || (yorn !='Y'))

|| is an or operator which will allow it to check both possiblities

Ok changed everything you have stated, but it still marks something wrong with the <iostream>.

[code]//Guess my Number (inverted)
//The computer will guess your number
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main ()
{
int myNumber;
char yorn;
cout <<"Enter a number between 1 and 10: ";
cin >> myNumber;
cout <<"\nYou chose "<<myNumber <<" as your number.";

srand(time(0));
do
{
int theNumber = rand() % 10 + 1;
cout <<"Is your number "<<theNumber<<"? (y/n)";
cin >> yorn;
} while ((yorn != 'y') || (yorn !='Y'));
cout <<"I won !";
return 0;
}
[/code]

This is what it marks.

Change the file to test.cpp (or test.cc). I would guess that the IDE is seeing the .c extension and attempting to use gcc (C compiler) instead of g++ (C++ compiler). The code you are trying is only valid C++.

Oh, you're using Dev C++, its old as **** and doens't actually compile standard C++ code.

try changing your includes to #include <iostream.h> <stdlib.h> and <time.h> (it might also work to rename the file test.cpp and not change any code if Dev C++ is better than i remembered).

Alternativly you could get a modern compiler.
