This time we just familiarize ourselves with Judian - it's core principles and basic building blocks - game objects, collections of those and components.

This is a generic guide for Judian beginners and enthusiasts, but also for anyone interested in what components are used in video games.

As a natural continuation of explaining how computer graphics are rendered, in this tutorial we dive into Judian Render Script.

Do you want to create breathtaking visual effects? Photorealistic or stylized games? You need to dig into how rendering works!

This video tackles a very frequently asked question - How to make lighting? Watch this video to learn how to add post-processing to your game with Screen Space Light Maps and implement it in Judian!

This video begins a tutorial series on making a simple space shooter game in Judian - similar to Galaga or Warblade, with a top down view and hordes of enemies you can shoot of with lasers and rockets.

Continuing the tutorial series on making a simple space shooter game in Judian! This time you will learn how to utilize collisions for detecting if enemy ships were hit by a projectile.

This is the 3rd, last part of the tutorial on making a very simple space shooter game like Galaga or Warblade in Judian! This concludes our effort to start game development with a quick project.

Let's take a look at Arcweave - a web tool to create interactive and branching games narratives with an export for Judian game engine.

In this session you’ll learn about how to install Judian on your desktop (Mac or Windows) as well as get oriented to the Judian Editor.

This session will provide instructions on how to load images to your Judian game project as well as how to position them within your game. Some basic animation techniques are also described.

A walkthrough is provided on how you can support a user selecting a specific game object and dragging it to a new location within your game.

This tutorial describes the procedures needed to move a Game Object using either a pre-defined path, or based on user inputs via mouse or touch.

Leveraging Judian’s Physics Engine – this tutorial reviews the concept of a collision object, used to trigger when one game object touches another, effects of gravity and bounce features.

A detailed description is provided on how you can incorporate button animations within the GUI as well as text notifications to users.

The final tutorial in this introductory series provides an explanation on how to accommodate multiple game levels to support different scenes or game chapters – as well as how to exchange information between game components.

This Tower Defense Tutorial will teach you the basics on how to incorporate the following features into a game: (1) splashscreens, (2) level selection menus, (3) help screens, (4) tank strikes, (5) tower placement, (6) fire exchange, (7) health resources, and (8) victory conditions.

This second video in our Tower Defense Series will focus on the design of Tank Collections and a Game Object representing the Enemy Tank's Final Objective.

Hang on for this third video in our Tower Defense Series – it focuses on game design techniques that facilitate the spawning of both Defensive Positions and Tower Collections, as well as supporting the ability to drag and drop Tower Objects across the game screen.

You just can’t have a Tower Defense game with modeling the exchange of gun fires between your deployed Towers…and the series of Tank Strikes that move toward their objective.

This fifth video in our Tower Defense Series will focus on design mechanics that support the inclusion of both a Resource as well as Health set of Scoring criteria. Additionally, it will address the addition of a popup that will let you either repair a tower, upgrade a tower or sell it outright.

This last video in our Tower Defense Series is going to focus on a couple pretty important concepts: (1) pausing a game using the Judian Collection Proxy Component, and (2) adjusting several game parameters within the game to achieve game balance.
