Tank Battle 3D!•3rd person tactical shooter with hover tanks

•Science fiction setting

•Enemy tanks, turrets, and mobile mines

•Player must fight through a maze full of enemies to reach the end goal

Gameplay Features• Mazes are dynamically created

• Multiple ammunition types

• Control tank using Xbox 360 controller or a keyboard

Target Market• Players who enjoy

• 3rd person shooting games

• strategy style gameplay

• maze style maps

Marketing• Free and low-cost advertising

• social networking websites• Facebook, Twitter, Google+, etc.• be able to reach about one billion people

Competition• Introducing our competitors

• Wii Tanks for the Nintendo Wii

• Crazy Tanks for mobile devices

• Tank Recon 3D for mobile devices

We aren’t the only ones to think of this!

Development Methodology• Core development is done in parallel

• Kevin works on A.I., Matthew works on menu• A.I. and menu system integrated together

• Unity game engine (free version)• C# used for script development

• Most art assets are created using Blender• some projectiles created within Unity

Development Methodology cont.• Iterative Use Case Driven Development

• 23 cases total• 2 - 3 life cycles for each case• Use case requirements • development • testing

• Weekly Updates• Senior project instructor: Professor Duncan• Technical advisor: Professor Bahrt

Version Control• Google Code

• cloud storage

• Tortoise SVN (Subversion)• version control system

• WinMerge• manual file merging

Tools for more sane projects, and project teams

Testing• Testing occurred throughout each feature

implementation

• Play testing using multiple subjects for feedback

Does it do what you want? Why not?

Unity!• Compared to Unreal Engine 3, Unity gave

us:• ability to layer objects for collision

• on the fly variable changes using the Inspector

• on the fly compilation when executed in the editor

• rapid implementation of the game

Graphical User Interface• Link menu system to empty Game Object

• developed using Unity’s stock GUI system

• switch between menus using a delegate • a data type that references a method• behaves like method once assigned one

• HUD (Heads Up Display)• also uses Unity stock GUI system• textures used for health & power-up meters

and for ammo and power-up type icons

How we designed our Rooms

Final Level 1

Artificial Intelligence

• Turrets• Arc rotation

• Mobile minesSeek, and destroy

• Tanks• Seek, and attack

• Group level behavior (future iteration)

Procedural Maze Generation• Room filling algorithm.

• Place starting point

• Determine if an additional room fits

• If so place it

• If the space is not filled repeat

• Otherwise exchange one of the rooms for the end.

Setting up for success• We have reached this point to better provide

for future implementations:

• more behavior states for the A.I.

• health bars for enemies

• finalize implementation of procedural level creation.

Lessons Learned• Developing the game using C++ and DirectX

• integration• knowledge

• Procedural Room Generation

• Explosion SFX• one reference script for each explosion

• We overcame each other’s differences
