The Problem

I wanted to create a tool to animate scenes, and humanoid characters.

Eventually I want be able to create complex animations which can be loaded into a 2d game.

This would take too long for a 427 assessment, so I've simplified the problem to having an interactive stickmen tool. The extensibility of the design of the system is critical so I can extend it in the future.

The system was fully designed and implemented in C# for COSC427, and was not based on previous work.

A screenshot of the current version is shown below.

System Goals

Within my 427 Project

• Customisable backgrounds
• Posable figures (Such as Stickmen)
• Props
• Extensible - so I can add the below features eventually

Outside the scope of this project, but to be added in the future:

• Interpolation between Keyframes
• Advanced Inverse Kinematics & Constraints on Joints
• Export angles & positions as animation file to be used in games

System Design

The image below is a simplified UML class diagram of nearly all of the classes in the system.
