Introduction

• Motivation– Promoting HKUST in a creative way

• Objective– Develop an adventure

game with attractive graphics, settings, and story lines

Introduction• Game Story

– In the Stone Age, the world suffered a dark period and was controlled by the dark king.

– The character needs to save the world from danger.

– The character gains sufficient experience and fighting skills by killing monsters and completing missions to challenge the dark king.

Results – Game InterfaceA character is speaking to the player Messages Skills Learnt

Hit Point Spirit Point Level Experience Coins Collected

Results – Fighting System

• Main feature:– Decide whether the enemy is hurt or the chara

cter is hurt during combat.

• Implementation:– Mainly Controlled by AI() function in each ene

my class

Results – Missions• 5 missions

– The Fire Dragon Mission– The villager Mission– Mr. Horner Mission– The Water Elf Mission– The old tree man Mission

Feature: gain a skill after completing

one mission

Results – Events

• 4 major events– The tutorial elf– The replenish well.– The HKUST landmarks.– The challenge to NPCs.

Results – Skills

• 4 combat skills– Golden skill– Water skill – Fire skill– Forest skill

• 1 special ability– Eagle eye

Results – Equipment

• 4 Pieces of Equipment

Arm ring

Leg ring

Helmet

Armor

Results – Camera

• Normal view

• Short view

• Far view

• Front view

• Side view

• Rotating view

Results – Mini Games• Two Mini Games

– Coin Gambling• Similar to the “Paper, Scissor

s, Stone” Game• Winner will gain coins; loser

will lose coins– Skiing

• Ski down an ice mountain at a high speed to get as many coins as possible.

Results – Stone Age Environment

• 14 different locations on HKUST campus simulated in a Stone Age style

Results – Sound/Background music

• 60 sound files for sound effects and background music

• A particular sound for each action• Different background music for different maps

• Difficulties in generating valid 3D models for the game engine

• Reason:– 3DS MAX Studio 5.0 failed to generate a valid .act file

for Genesis 3D

• Solution:– Used another 3D modeling

software-- Milkshape3D

Problems Solving– Problem 1

Problems Solving– Problem 2

Very slow frame rate caused by complex 3D models

• Reason:– The area and number of 3D models are to

o complex to be rendered together.

• Solution:– Divided a large map into a number of

small sub-maps– Used “way-point” idea to link two maps

Problems Solving– Problem 3

Unstable speed of the game• Reason:

– 1. Complex view results in low frame rate; different view results in different frame speeds.

– 2. Fast computer will result in a high frame rate and the action is too fast; different computers result in different frame speeds.

• Solution:– By calculating the time used

in each loop, the program adjusts the number of frames per second for the motions of the character.

Conclusion• Major Achievement

– Designed and developed a stimulating game which can be used to introduce our campus to visitors and freshmen.

• Future Extensions– Option to choose different characters– Riding abilities

• Q&A Session– Please feel free to ask questions.
