A simulation that find outs if the hero would survive or not.

Please read Instructions.md to better understand project requirements.

How to run?

• Install a recent version of IntelliJ IDEA. Kotlin is bundled with IntelliJ IDEA starting from version 15.
• You can download the free Community Edition from JetBrains.
• Download the project as zip file.
• Unzip the downloaded file.
• Open the project folder from from Intellij IDEA.
• Run!

Project structure

The project has 3 main components.

• main.kt: Main Kotlin file where the application starts its life.
• controllers: The package contains logic and engine related files. It consists of 2 objects: -- Data: For data handling jobs like, reading, writing and mapping. -- Simulation: Process the valuable information and make the simulation happen.
• models: The package contains the classes. It consists of 5 classes: -- Creature: Main class holds the main and common variables, other living creatures like Hero" and "Enemy" will be inherited from this main class, -- Enemy: Class for enemies, inherits from the "Creature" class. -- Hero: Class for hero, inherits from the "Creature" class. -- Resource: Class for resource. -- MappedData: Class for the data that we read from the "input.txt" file.

How does it work?

This project has developed in Andorid’s official and JVM language “Kotlin”. The general flow of the application is as it follows.

• Define the variable readFileName, default value is input.txt
• Call the readFile() function from Data object by passing the value readFileName as an input parameter to read the input file and assign its return value which is an instance of MappedData class to the mappedData variable.
• readFile() function reads the input.txt line by line and adds it to inputLines list which stores each line of the given input text file as an item. This function returns the instance of MappedData class by passing the variable inputLines as an input parameter to dataMapper() function.
• dataMapper() function is actually do the data mining job by extracting the valuable information from the inputLines list which is equal to the information in input.txt file. After organising the necessary information and assigning them to relateed variables, returns it as an instance of MappedData class by executing return MappedData(resource, hero, enemyList) .
• We red the file input.txt and stored the necessary information for simulation in the mappedData variable which is an instance of MappedData class. Now we can call the start() function from Simulation object by passing the mappedData variable as a parameter by executing Simulation.start(mappedData) .
• start() function initialises to simulation by extracting the wrapped information from mappedData variable and assigning the values to the related variables and then starts the while() loop which represents our hero's movement.
• while() loop continues till the hero reaches to the position of the resource or until he/she dies. Inside the while() loop there is a for() loop that loops through the enemies and calls the fight() function each time by passing the Pair(hero, enemy) variable as a parameter if their positions meets.
• fight() function simulates the fight between the hero and the enemy. The parameter pair holds the instances of Hero and, enemy Enemy classes. And returns Boolean that represents if the hero won the fight or not.
• In the end we reach to the end of start() function where we call writeFile() function by passing the journeyLog variable as a parameter.
• writeFile() loops through journeyLog variable and writes it line by line to the text file called output.txt. If the file exists with the same name it numbers the file name starting from 1. For example output1.txt, output2.txt, output3.txt...
