Thread: help with really simple rpg

i have only been working with C++ off and on the last few weeks and this is my first semi large project

here is a what i want to do (instructions in code)

Code:

	//i want to display all this stuff as a item menu and link to it from various places
	cout<<"Items\n";
	cout<< item1 << "potions or something\n";
	cout<< item2 << "something else!!!!\n";
	//end of the stuff i want as an item menu
	
	do {
		switch (room) {
		//room coordinate 1,1
		case 11:
			if ( man11hp > 0 ) {
				cout<<"There is a man standing in front of you.\n";
				cout<<"(a)ttack\n";
				cout<<"(r)un\n";
				cout<<"(i)tem\n";   // when i hit input "i" i want it to link to the item menu
				cin>> action11;

that is just a small section from the code, before it is just a bunch of variables i have declared

its not something thats not working, its just something i dont quite know how to do yet... and a space would be good

you could just make a seperate function called menu or something

thats what i dont know yet...
i read the function tutorial but i dont really get how to implement that...

example in text format if a condition is met

Code:

#include <iostream>

using namepace std;

int main()
{

int potion = 0;   // define and initalize your items
int sword = 0;

sword++;   // increment them
potion++;

// display a message

if ( potion >= 1 )
{
cout << "I have a potion" << endl;
}

if ( sword >= 1 )
{
cout << "I have a sword" << endl;
}

return 0;
}

number list option

Code:

 // assume you have the required amounts....

int potion = 1;
int sword = 1;

cout << "Sword: " << sword << endl;
cout << "Potion: " << potion << endl;

the above is a snippet, but you get the idea. Also avoid using GLOBAL variables. Use a class like the example below and send the information via a function

Code:

class Inven
{
public:
Inven();  // constructor to implelent the variables

private:    // use private for vairable names
int health;
int potions;
string myName;
};

these are all good seggustions, but the part i really need help with is using the function to see it from different parts of the code, as i asked in the first post

here is one method - this assumes you have collected the items

// this function stores your items

Code:

void storeItems ( void )
{
cout << "Potions: " << potions;
cout << swords: " << swords;

return;
}

nest snipped of code in selection example:

Code:

switch ( choose )
{
case 1:

// call the inventory function

storeItems();

// check to see if you have item
i
f ( sword >= 1 )
{
useSword();  // call a function that actions the sword being used
}

else if ( sword <= 0 )
{
cout << "You do not have the sword;
}
break;

the sword use function could be this:

Code:

void useSword( void )
{
cout << "What action?\n"
                       [R[un\n"
                       [A]ttack\n"
                       > ";
cin >> choose;

switch ( choose )
{
case 'A':
--enemyHp;
cout << you attack and hit enemy;

break;
}

this is a small version of a way to do it. read up on functions to learn more
