Agenda
———–
1] Update
2] Reflections on what transpired last week
3] to-do

Update
The team read through and is in the process of compiling the Innovation Engine into XP-Dev
Abit of research on individual parts

Reflections
Input from Allan:
3D Game is wide (complex) and difficult to implement
individual’s parts are dependent on each other, ie. Map Representation -> Pathfinding -> AI, etc
advise is to scale down on implementation so as to fit into project timeframe
features to show must be obvious (eg. clever AI must be able to be observed by player)

To-Do
Meeting the next day to sort out product backlog and plan sprints
Follow-up on relevant people for update on xbox loan, creators’ club premium account, schedule for meeting with Claude and Dr. Ashraf, updating Allan on meeting timings

part 2 coming up after tommorow’s meeting

Course of Action after the long weekend:

• We should all install Microsoft Visual C# 08 Express + XNA Game Studio 3.0
  • Dennis and Chow will help install these on several PCs in Media Lab 2 (yay)
• Still PC development with plans for 360 porting but we should still try to loan out a 360 from school to test porting early on.
• Complete the tutorial from Innovative Games shape up the engine
• I believe the Creators Club paid account by the school should give premium download access, should try to get our hands on both Robot and Ship game
• Discuss, re-evaluate and streamline what we want. Should aim lower and finish a complete game. We can always go back to rework on it after the semester.
  • This means revising our product and release backlogs.
• Arrange meeting with Claude on Thursday

Reference Books

Went to Clementi Book Store to look for reference books. Tenatively we will be deciding on this book: Microsoft Xna Unleashed : Graphics and Game Programming for Xbox 360 and Windows.

Game Engine

We took a look at a few ready 3D XNA game engines, but could not find a suitable one. We decided to use the tutorial for building a 3D XNA game engine at http://innovativegames.net/ to start a game engine from scratch. This will enable us to understand the internals of a game engine better.

Follow-up

Platform

School only has 2 Xbox 360 for possible loan. Anselm’s still on the way. I might be able to loan one from friend who works at Microsoft. We’d try to develop for PC with Xbox 360 controllers first. At least for initial few releases until we can settle deployment problems for the Xbox. Worst case scenario would be to fully develop on PC and port to 360 at the end of the day.

Meetings

Meeting timing with Dr Ashraf is tentatively set for Thursdays or Fridays. To check with Claude.

Game Design

To-Do

• Check pricing of Xbox controller + bluetooth dongle
  • Update: 75.90 per piece w/o dongle
• Arrange fixed timing for meetings with Claude & Dr Ashraf as well as free time for group programming/discussion. To be confirmed once tutorials are allocated.

Release 1 planned

• Current state of the map generated using a height map and code
• Attempting to add in tree using a tree map
• Adding more assets like buildings and bridges

Traps are currently only for outdoor part of the map. The map will have environmental materials that will be used to build traps. A trap-builder will be able to survey the surroundings and determine what materials are available and thus which traps are able to be built. However, the game does not require the player to go gather these materials. The trap-builder will then be able to choose the best choice of available traps to be build at the best location automatically. For example, the trap-builder will give a high rating for a boulder trap put on a slope and low rating for a boulder trap on flat land. A trap is triggered by the opposing party once it touches the trap, and a penalty will be given. Traps will be visible to the opponent, but the visibility (alpha value?) of the trap will have an inverse relationship to the goodness of the trap. That means a trap with higher rating value will be less visible to the opponent.

Given below is a rough list of the materials, traps and their attributes, which may be amended and expanded.

Types of materials:

Environmental Materials:

• Water
• Sand
• rocks
• wood
• leaves

Default materials (inexhaustible):

• spade (hole digging)
• trip wires

Types of traps:

In order to balance the game, the monster layout will be something like below

monster distribution

TBC. Add any map related stuff here!

Monsters are catergoried into a few types, namely

1. physical / magical / hybrid
2. side a* / side b* / neutral

Some of the monsters, when nearby with another type of monster, might be able to execute a combined skill attack.

Monster table

* to be changed to an appropriate name for the side
(P), (H), (M) denote physical, hybrid and magical types respectively

In addition to these monsters, there will be passive creatures, chicken and goats, roaming the game world.

This section describes features of the character class in the game.
The current version is not final. Numbers and formulas are now simplistic and subject to testing in order to balance the gameplay.

External Attributes

• Morale
  Morale will have a direct impact on the character’s attributes (as well as of all friendly troops).
  Formula:
  Morale 50% (Default) -> Vigor, Sorcery 100%
  Morale 0% (Minimum) -> Vigor, Sorcery 50%
  Morale 100% (Maximum) -> Vigor, Sorcery 150%

Attribute Gain

Attribute gain will be hidden from player. Players do not need to assign any of their character’s attributes.
Player’s action however will have a direct consequence on the growth of their attributes. This allows for many different possible character builds.

Players will increase their vigor and sorcery attributes when attacking monsters or enemies. This will in turn affect the other attributes.

Formula:
Each point of vigor / sorcery will require 20 points of experience to level up. The rules which governs the gain of attribute experience is described below.

1. Attacking using physical / magical skills will increase 1 experience in vigor / sorcery
2. Killing an enemy of physical type will increase 3 experience in vigor
3. Killing an enemy of magical type will increase 3 experience in sorcery
4. Killing an enemy of hybrid type will increase 2 experience in vigor and 2 experience in sorcery

Skills

Skills will be unlocked based on the character’s vigor and sorcery attribute.
The fury attack is a special attack which can be used when the fury meter is maxed out.
