Explanation of calculating collision between basic 3D objects (rectangular solids/cubes and spheres). Methods used can be applied to any programming language or game development environment. Review of demo Ruby code to detect collision between rectangular solids and spheres.
Explanation of 2D collisions for points, lines, rectangles, and circles. Overview of each collision type along with examples and code. Explanations are general in nature so that they can be implemented in any game engine or programming language. Demonstration of Javascript web application that calculates collisions between the four types of objects, along with review of code functionality.
Explanation of Dijkstra’s algorithm for finding the shortest path in a graph based on a selected starting node. Walkthrough of an example of the algorithm. Demo of implementation of Dijkstra’s algorithm in Unity and C#.
Overview of the Stencyl game development environment for making 2D games. Explanation of scenes, actors, behaviors, events, and visual coding. Examples of a number guessing game and simple space shooter.
Demonstration of how to play a sound effect in various game development environments. This presentation covers Unity, GameMaker, Godot Engine, Unreal Engine (Blueprints), and Pico-8.
This month’s Knox Game Design covers the BXFR tool for generating sound effects for games. A look at different sound effect types, modifying sound effect properties, using the mixer to combine effects together, and an analysis for the various types of wave forms.
Comparison of file types for holding image data for textures and sprites in games. File types include BMP, GIF, PNG, JPEG, SVG, TIFF, TGA, PCX, HEIC, and WebP. Properties include transparency, compression, lossy vs lossless, and file size. Demonstration of how to programmatically decode and encode PNG files. Compatibility of image files with four game engines (Unity, Unreal Engine, Godot Engine, GameMaker).
The Spring ’21 game jam is Friday April 23-26, 2021. Meet with us at The Kitchen at Crafter’s Brew in Oak Ridge for a game jam kickoff at 7pm Eastern Time on Friday April 23, 2021. For more information on the game jam see ldjam.com. If you make a game, let us know on our Discord channel and we will add it to the website!
Overview of comparison of data types, sorting algorithms, and run times. Demonstration of sorting in Unity with C#, GameMaker with GML, Godot with GDScript, Unreal Engine with C++, and Pico-8 with Lua. For each game development environment, examples are shown for sorting integers, character strings (words), and a custom object type.
