Thread: movement question

I'm making the class or whatever that will let the computer tell where the player is at according to an array. How could I have the program test for the characters within the array and do things according to what character is in the position the player is in. Here's the code:

Code:

#include <iostream>
using namespace std;

#define NUM_ROWS 3

#define Church_ID 'c'
#define Item_ID   'i'
#define Weapon_ID 'w'
#define Armor_ID  'a'
#define Road_ID   'r'
#define Wall_ID   '*'

/*********************/
//c = church
//i = item shop
//* = not accessible
//w = weapon shop
//a = armor shop
//r = road
/*********************/

char *FunkyTown[NUM_ROWS] = {"cri",
							 "wra",
						 	 "*r*"};

class move
{
private:
	int xpos;
	int ypos;
	int ymax;
	int ymin;
	int xmax;
	int xmin;
	int previousYpos;
	int previousXpos;
public:
	move()
	{
		xpos = 1;
		ypos = 3;
		ymin = 1;
		ymax = NUM_ROWS;
		xmin = 0;
		xmax = 2;
	}
	void position(int value)
	{
		previousYpos = ypos;
		previousXpos = xpos;
		if(value == 1)
		{
			ypos--;
			if(ypos <= 0)
			{ypos = ymin;}
			else if(ypos > 3)
			{ypos = ymax;}
		}
		else if(value == 2)
		{
			ypos++;
			if(ypos <= 0)
			{ypos = ymin;}
			else if(ypos > 3)
			{ypos = ymax;}
		}
		else if(value == 3)
		{
			xpos--;
			if(xpos <= 0)
			{xpos = xmin;}
			else if(xpos > 2)
			{xpos = xmax;}
		}
		else
		{
			xpos++;
			if(xpos <= 0)
			{xpos = xmin;}
			else if(xpos > 2)
			{xpos = xmax;}
		}
		if(xpos == 0 && ypos == 3 || xpos == 2 && ypos == 3) //this is the easy way I test
		{													 //to see if the player hits a wall
			xpos = previousXpos;							 //without using the array at all.
			ypos = previousYpos;
			cout << "You can't go that way, its a wall." << endl;
		}
	}
	void displayPos()
	{
		cout << "Current Position: " << (xpos+1) << "," << ypos << endl;
	}
};

void main()
{
	move character;
	int choice = 0;
	cout << "Movement Test v1.0" << endl;
	while(choice!=5)
	{
		cout << "1 Move North" << endl;
		cout << "2 Move South" << endl;
		cout << "3 Move West" << endl;
		cout << "4 Move East" << endl;
		cout << "5 Quit" << endl;
		cout << "Choose: ";
		cin >> choice;
		system("cls");
		switch(choice)
		{
		case 1: character.position(choice);
			break;
		case 2: character.position(choice);
			break;
		case 3: character.position(choice);
			break;
		case 4: character.position(choice);
			break;
		case 5: break;
		}
		character.displayPos();
	}
}

I'm probably doing this the wrong way totally, any help would be much appreciated. Thanks in advance.

what's wrong with your code, what errors do you get
1 more thing when u have a constructor dont u have to set it in your main somehow i dont remember it right now but i'll go read about it now please post your errors.

I got it to work finally. Thanks Magos.

I wasn't getting any errors, the program just wasn't working the way I wanted it to. The constructor is called whenever you create a variable using the class, ex. "move character". The point of the contructor usually is to initialize all the variables in the class
