KihonEngine

Kihon Engine is a basic 3D engine developed in dotnet core and WPF. It can be used for developpinng basic 3D video games.

Actually, with Kihon Engine, you can:

• Build maps with Kihon Engine Studio.
• Run maps in a basic FPS game mode and walk around the map in first person view.

Getting started

Create a video game based on Kihon Engine is very easy.

Just take a look inside the sample project KihonEngine.SampleGame .

The whole MainWindow.xaml.cs should look something like this:

namespace KihonEngine.SampleGame
{
    using System.Windows;
    using System.Windows.Input;

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            // Step 1 : Configure game engine
            Engine.Configure();

            // Step 2 : Configure game : we will use an existing map from KihonEngine.SampleMaps
            StandardStartups.BuildStandaloneFullScreenGame<KihonEngine.SampleMaps.DarkCastleMapBuilder>();

            // Step 3 : When click Start button, launch game
            btnStart.Click += (sender, e) => Engine.Play();

            // And then, manage how application ends
            btnExit.Click += (sender, e) => Close();

            KeyDown += (sender, e) => { if (e.Key == Key.Escape) { Close(); } };
        }
    }
}

And that's all. When the application starts, you will have basic startup screen.

And by click Start Game, you will launch one of the few sample maps available in KihonEngine.SampleMaps

Kihon Engine technical architecture overview

Kihon Engine global architecture is the following

Kihon Engine Studio

Kihon Engine Studio helps for building maps

The actual basic features are the following

Some generic features

• Save and load maps from files based on a json format
• Possibility to change map global properties like map name, respawn player camera (position and direction)
• Source viewer for the currently edited map, in order to visualize the json format
• Game state viewer to analyse game state at any time
• Possibility to switch between edit mode and game mode in order to vizualise how map is rendered at play time

Edit mode

Play mode

Adding 3D models to maps

• Add floor
• Add ceilings
• Add walls
• Add volumes, like cube, rectangles
• Add lights to make the viewport3D scene visible
• Add skyboxes. Actually, three predefined skyboxes are availables

Possibility to edit the 3D models

• By dimentions
• By colors
• As proof of concept, actually only four textures are available for floors

Possibility to move 3D models on the map

• By rotation on axis X, Y and Z
• By translation on axis X, Y and Z
