2d Fighting!!

It's a open-world-adventure game in 2d !

Hello welcome to my game, you are the selected hero from your village to defend your village from monsters.

Intro

You are the selected hero from your village to defend your village from monsters around it. You always dreamed to be the hero of the village since young. Now it's time for you to shine. Prepare for all kinds of adventures, monsters, traps, you will encounter. All that you know is that this is hard, but you know that with great power comes great responsibility. So you must go on and defend your village. Be the hero. Wish you good luck!

(Note: you must go before the dark as nearby monsters attack your village at night.)

Prerequisites

You are given at most a 5*5 map since your village don't have a lot of paper to make you a map.

For Example:

Your default stats (Player)

Blood: 10
Strength: 2
Hunger: 20
Coins: 10
Level: 1

Your village's default stats

Blood: 50
Strength: 0
Level: 1

If your strength / hunger / coins = 0

If you don't have enough hunger or strength the next time you lose either of them you will lose blood. But if you don't have enough coins (coins = 0), your coins will just be 0 if you lose them next time.

How to play / Rules

You start from day 1 of defending the village. When you move 1 spot, it takes a hour and your hunger will be deducted 1. So, in a day, you can only take 24 steps (unless you have potion of swiftness ) before it gets dark. When it's night time, your village will be attacked by nearby monsters (if you can see them from the map in the village's perpective means is nearby)

For Example:

village's perspective means the village is in the middle of the map

each nearby monster will have 10 damage times days you survived to the village. Once the night is over and you and your village are both still alive everything will reallocate to their new places except you and your village. This will start a whole new day of defending your village with new and more unexpected things to come. Your default blood will be added to 20. Your village will become stronger with 50 more blood. But if the village falls down or 'you died' during the day, you fail your mission, and the game is over.

For example (after the night stats):

Your day 2 stats (best condition) (Player)

Blood: 20
Strength: 2
Hunger: 20
Coins: 10
Level: 2

Your village's day 2 (best condition) stats

Blood: 100
Strength: 0
Level: 2

Summary of the game

You and your village can't fall down.

Basic Interfaces

Basic

There are two main kinds of spot in the game. One is '.' and others.

Spots in map	Status
'.'(dot) / 'p'	normal
'm' / 's' / 'f' / 'c' / 'h'...(even hidden ones)	special

Whenever you see a map, you are in the dead center of the map. If you don't see 'p' doesn't mean you are not on the map, it's just that you are standing on a special spot.

Movement Interface

Ask which direction to go or you want to use inventory or see map or quit game.

After movement Interface

Each time after you move you will be given all kinds of information.

Village's stats
Your stats
What is in your inventory
Effects on you
Map
Coordinate (Yours and Village's)
Time of the day
Small reminder

Village Interface

Ask what you want to do in the village

Dealer's Shop Interface

Ask what you want to do in the dealer's_shop

Inventory Interface

Setup

Intro

The game will first welcome adventurer and give you your stats. And then it will ask you to input the rows and columns of the map (suggestion: square and 50*50 or up) and then it will ask you to input the coordinates of the village. Then, you can choose to create a new map or start playing. You always start from the village.

Item setup

Items	How Many
Player	one
Village	one
Dealer	map size * 1/12
Monster	map size * 1/8
Food	map size * 1/8
Guns	map size * 1/24
Shield	map size * 1/24
Traps	map size * 1/24
Fast Travel Stations	map size * 1/48
Health Stations	map size * 1/48
For example: a 50*50 map

The location of the items are randomly generated except for the village.

Items in the game

Player

Is you

Is 'p' on the map

see stats

Inventory (How to use)

Before you move, you can always use your inventory. You just need to type '0' and you can use it.

Your Village

Is 'v' on the map

see stats

What can you do inside the village

Buy a magical sword

Each sword is 3 coins and will give you 1 strength. You can only buy once per visit.
Go to the bar

You can drink beer in the bar which will give you +1 blood. Each beer is worth 2 coins and you can drink till you are back to health.
Eat a meal

Each meal is worth 5 coins and will give you +5 hunger. You can eat till you're full.
Sell things

You can sell things from your inventory but each thing is only sold for 5 coins.

Dealer Shop

Is 'd' on the map

The dealer shop is like a black market. It can highly improve your game. It sells unique things that you can't normally buy in your village. But because of this you can only buy stuff from this dealer shop once. Once you leave the shop you can only visit other shops in other locations, the shop you visited will disappear to avoid being arrested by the cops (there are actually no cops in this game, it is just to tell you that it is like a black market, and it will not be in the same location after you leave).

Things in the Dealer Shop

Potion of Swiftness

Makes you go faster, you can walk two steps at a time with only -1 hunger. Effect lasts till the day ends. Costs 25 coins.

Totem of Undying

You won't die if you have this. It will give you +5 blood when in need. Costs 50 coins.

Golden Apple

When you eat it, it will give you +5 blood and +5 hunger. Costs 55 coins.

Potion of Good Vision

You can see 11 * 11 map everytime you see the map. Effect lasts till the end of the day. Costs 30 coins.

How to use the items

You have to go in your inventory (see how to use inventory ) and use it then the item will be in effect. For example, you want to use the totem of undying, go in your inventory and use it then it will be in effect otherwise no.

You can buy a lot of them but only use 1 of them (only 1 can be in effect)

Monster

Is 'm' on the map

There are four levels of monsters. When you encounter a monster, the levels of the monsters are randomly generated. You then can choose to fight or not to fight. If you choose to fight your hunger will first be deducted by the monster's strength, as you will need tired and hungry after the fight.

Monsters	Stats (Day 1) (Default)
Lv. 1	Blood: 1 Strength: 1 Coins: 5
Lv. 2	Blood: 2 Strength: 2 Coins: 10
Lv. 3	Blood: 3 Strength: 3 Coins: 15
Lv. 4	Blood: 4 Strength: 4 Coins: 20

Monster's Stats = Default Stats * (Days you survived) . For example, on day 2, a lv.2 monster will have 4 blood, 4 strength, and 20 coins.
When you encounter a monster, each monster's evasion rate will be randomly generated, and when a monster successfully evaded your attack, it will attack back (will lose blood). If it didn't evade, it means you attacked successfully if your attack is greater than their blood. You will get the coins and your strength will be added 1, but if your attack is lesser than their blood, it means you lost, and you will be attacked (will lose blood). The monster won't go anywhere if you lose, so you can always come back again(may be different level). But the monster will disappear if you win, because you just killed it.

Food

Is 'c' on the map, as it stands for chicken or cow

When you encounter a "food", you can eat it, and your hunger will be added 2. If you are already full, then the game will say you are full and you don't need to eat it (to save animals). But the animal will go nowhere so you can come back anytime. But if you are almost full (if +2 hunger will be greater than 20 hunger) then you will only be added to 20 hunger.

Guns / Shields / Traps

They are all over the map, but hided from you( can't see from map ) . Each '.' may be a gun, shield, or a trap, so walk with caution. After you stepped on it, it will disappear (not in the same location).

Hidden Items	Description
Guns	Will give you strength. ( strength +1 )
Shield	Will give you protection ( blood+1 ).
Trap 1	Will lose 1 blood and 1 strength
Trap 2	Will lose coins

The amount of coins you lose is somewhere between 0 to half your amount (random). So don't be worried.
If you don't have any strength (strength = 0) then the next time you lose strength you will lose blood. see if your strength/hunger/coins = 0 for more info

Fast Travel Stations

Is 'f' on the map They can help you travel back to the village right away if you want.

Health Stations

Is 'h' on the map It will give you +1 blood. But if you are already healthy, you don't need it.

{
    int decide; // decide to create a new map or travel
    printf("[0] Create a new map [1] Start travel the map:");
    scanf("%d", &decide);
    return decide;
}

Check for availability and boundaries

Human input check

Check boundary

int check_boundary(int *row, int *col, int r, int c) // row temp and col temp to see if input is in the correct range
{
    if (r >= *row || r < 0 || c >= *col || c < 0)
    {
        printf("the location is  outside the map\n");
        return 1; // true
    }
    else
        return 0; // false
}

Check availability

int check_availability(char **map, int *row, int *col, int r, int c)
{
    if (map[r][c] !='.') // check if occupied
    {
        printf("the location is occupied\n");
        return 1; // true
    }
    else
        return 0; // false
}

Computer input

only need to check availability cause computer won't input a row or column out of range (I coded it)

Check availability

int comp_check_availability(char **map, int *row, int *col, int r, int c)
{
    if (map[r][c] != '.') // check if occupied
        return 1;         // true
    else
        return 0; // false
}

Human typed setup

     scanf("%d %d", &hero->rv, &hero->cv);
     if (check_boundary(row, col, hero->rv, hero->cv))//check if out of range
         setup_village(map, row, col, hero);//if yes then call the function again
     map[hero->rv][hero->cv] = 'v';//otherwise set coordinate to 'v'
 }
