Developer assignment

Welcome to the GamesLabs developer assignment. The goal of this assignment is to test your ability to use :

  • git
  • maven
  • component and event based programming
  • java programming
  • code quality
  • follow vague descriptions

Requirements

Before starting this assignment, you will need to have :

  • java 8+
  • maven 3+
  • git

The assignment

You will need to do different tasks. You may need to change the original code in order to complete these tasks.

Component based project

A component is a piece of code handling one feature, and only one feature. It can interact with other components through events. A component must extends the net.gameslabs.api.Component class.

Component cycle

When a component is loaded, the onLoad is called. You can register events in this method by doing so:

@Override
public void onLoad() {
    registerEvent(GiveXpEvent.class, this::onGiveXPToPlayer);
}

private void onGiveXPToPlayer(GiveXpEvent event) {
    // Do something
}

The onUnload method is called when the component unloads.

Events

You may send an event by using the Component.send method:

private void onGiveXPToPlayer(GiveXpEvent event) {
    int previousLevel = ...
    int nextLevel = ...
    if (previousLevel != nextLevel) {
        send(new PlayerGainLevelEvent(event.getPlayer(), event.getSkill(), nextLevel));
    }
}

Events go through components in the order they're loaded in (i.e. priority). If an event is cancelled, it will not go through lower priority components.

Main structure

Here is the list of the main packages of this project:

  • assignment This is where most of your code will be made. assignment.Main is the main class to execute
  • net.gameslabs This package contains mostly back-end code.
  • net.gameslabs.events A package containing the different events.

The main class

The Main class:

public static void main(String[] args) {
    new Assignment(
        new MyXPBoosterComponent()
    ).run();
}

The assignment class takes components in its constructor. Components are loaded in order.

The assignment

Here is the list of tasks you need to achieve:

  • Edit the MyXPBoosterComponent to enable DXP in the construction skill
  • Add an inventory component in charge of giving, checking if a player has a given item and removing a given item. In order to complete this task, you may need to edit pre-existing code. Add new checks in Assignment.java to run checks on the features you have added.
  • Add a mining skill and component with different ores. A player should only be able to mine coal at level 5 (meaning a, event needs to be cancelled according to his mining level). A player should receive xp from mining an ore. Add new checks in Assignment.java to run checks on the features you have added.
  • Add a unique feature and add this feature to the README with a description of what it is supposed to do and checks in Assignment.
