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 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
Code
The system was implemeted in C# and can be obtained here. To build and run is trivial -- Open Stickman.sln in Visual Studio and build. You'll need Windows and VS2008 or later.
System Design
The image below is a simplified UML class diagram of nearly all of the classes in the system.
