Background  Two overall goals: Expand upon 3D game engine built last semester. Create a fun, interactive game built on top of the engine.

Background  Using: Microsoft’s XNA framework (C#). Visual Studio Additional software for art and music development.

2. Schedule, Analysis  Schedule only started to fall apart toward the end of the semester.  Got most individual items done!  It was only the final integration that fell behind.

Cut Features  Particle Engine Very complex. Not enough time to implement correctly. Would have meant cutting other features.  Inventory System  UI The ability is there, but ran out of time!

Difficulties, General  TIME! The biggest problem is we ran out of TIME!  Integration All the pieces are there, but we lacked time to fit them together. We ran out of time for integration.

Difficulties, General  Man/womanpower Could have gotten a lot done if we had a small team dedicated to each development area.

Difficulties, Gameplay  AI algorithms were based on a 2D algorithm.  Translation to 3D proved challenging.

Difficulties, Art  Lack of suitable textures Each texture needs a diffuse, normal and specular map. Could only find a handful of suitable textures. Painting by hand is too time-consuming. Resulted in lots of tiling, which makes the art looks overdone and bland.  Inexperience Apparently this art stuff is kind of difficult.

Video Demonstration  And now, the moment you’ve all been waiting for…  Video Video

So how did we do?  Basically, all the pieces are there, we couldn’t put them all together in time.

So how did we do?  We did, however, accomplish a LOT!

So how did we do?  The engine is at the stage where anyone could pick up our code and build a game right now.

So how did we do?  The engine is at the stage where anyone could pick up our code and build a game right now.

So how did we do?  The game itself is not very playable, but there’s something there you can interact with.

So how did we do?  As a group, we consider the underlying code and art a success, but the lack of final integration our only weak point.  Overall, we are satisfied.
