This is a simple SDK for Code Of War 4 written with Java 8.

Clone this repository or download as zip file.

Once the source code is on you local drive, there are 2 solutions:

• integrating it as an IntelliJ module (IntelliJ module is under CoW4-Java/CoW4-Java.iml)
• adding sources and GSon library to your project.

CAUTION: The getShortestPath method in GameWorld class is very simple and very slow. You must implement your own one.

This SDK is very simple to use. Here are 2 steps to follow.

First instanciate a SocketManager and then call connectToServer method.

new SocketManager().connectToServer(
    "localhost", // server domain or ip
    8127, // port
    "My_troll_AI", // AI name
    "https://mydomain.com/my-avatar.png", // Avatar image url
    CharacterSkin.BARBARIAN, // Character skin
    Main::executeTurn, // Function to call or lambda function
    new StaticGameWorld()); // The game world

There are 2 types of game worlds:

• StaticGameWorld: In this class the labyrinth data is hard coded. This gives your AI more time to process its orders. (might not work perfectly)
• DynamicGameWorld: This class parses game data every turn.

When connected to server this SDK starts an infinite loop that listen server messages.

Once a turn message is read from server socket, the function you passed as parameter to connectToServer is called. Here is a simple implementation:

public static List<Order> executeTurn(GameWorld world) {
    List<Order> orders = new ArrayList<>();
    Cell cell = world.getMyAI().getCell();
    Cell[][] labyrinth = world.getLabyrinth();
    int myAiColumn = cell.getColumn();
    int myAiLine = cell.getLine();
    Order order = null;
    if (cell.canLeft()) {
        order = new MoveOrder(labyrinth[myAiLine][myAiColumn - 1].getId());
    } else if (cell.canRight()) {
        order = new MoveOrder(labyrinth[myAiLine][myAiColumn + 1].getId());
    } else if (cell.canTop()) {
        order = new MoveOrder(labyrinth[myAiLine - 1][myAiColumn].getId());
    } else if (cell.canBottom()) {
        order = new MoveOrder(labyrinth[myAiLine + 1][myAiColumn].getId());
    }
    orders.add(order);
    return orders;
}

As you can see, world contains all data you need to take your decisions. Your function should return an order. There are 3 types of orders:

• MoveOrder : Your character will move to a Cell
• PickUpOrder : If you are above an item this order pick up this item.
• UseItemOrder : If you have an item, you can use it.

tests package has 2 classes:

• PerformanceTests : Run this class as an application to measure getShortestPath processing time
• CellPathTester : Run this class as an application to launch a GUI drawing your paths. Use Shift + Click to place the starting point and Alt + Click to place the destination point.
