Class Grading
 20%: 10 Labs
 30%: 10 Assignments
 30%: 3 Tests
 20%: Professionalism*
2% Extra Credit for playtesting Game Fair games
* 35%+ absences is an automatic fail.

Labs
Game development is a team sport. Each of
your labs is a group assignment in which
everyone must participate.

Come Prepared
Having one of these is
a minimum
requirement.
At all times.

Assignments
Do your homework assignments on the LMS
(Learning Management System).

Word Counts
Word counts are there for a reason.
Use them wisely and avoid:
 Padding
 Going off topic
 Repeating yourself
 Padding by stating the obvious in a way that
takes quite a lot of words but really isn’t
saying anything new
 Repeating yourself but in a different way
 Padding, wadding, lining, extemporising,
extraneous content or going on any other
kind of Synonym Safari TM

Deliver Work On Time
Develop a habit of delivering work
on time.
In the game industry, when work is
late, people don’t get paid.
Pssst....Sometimes developers make false
internal deadlines to avoid calamity such
as missed milestone payments. Maybe you
could do the same if graduation is at
stake?

Tests
 Study for your tests! Refer to the
slides.
 If you see on a slide, it will
probably be on the test.
 If you don’t know the answer to a test
question, guess!
 There are no points deducted for wrong
answers on multiple-choice questions
 I will award some points for clever or
knowledgeable answers on short-answer
questions, even if they weren’t the answer
I was looking for.

First Rule of Success: Show Up
 DON’T BE TARDY
But if you know you will be
late, EMAIL ME!
 DON’T BE ABSENT
But if you know you will be
gone, EMAIL ME!

School Is Your Job
Yes, these are important:
 Part-time work
 Family
 Friends
 Fun
But don’t neglect your school work!

Impressions
Your colleagues and
faculty will most likely
be your doorway into
the industry.
How do you want them
to think of you?
ZERO HERO

Game Mechanic
 Action: What players actually do in the
game
 Purpose: The reason why players are
doing it

The Core Mechanic(s)
The action(s) that the player uses most
frequently to progress in the game.

Examples of Core Mechanics
Game Core Action Core Purpose
Chess Position pieces to capture opponent’s pieces
Candy Crush Match 3 pieces to destroy them
Tetris Rotate pieces to create lines
Super Smash Bros Attack to knock opponent back
Doom Run and shoot to kill enemies
World of Warcraft Kill to earn experience

 Write down an activity of any kind – related
to work, school, fun, chores, anything.
 Come up with a verb, based on this activity,
that you think would make a good basis for
a game.
 Identify:
 Core Action
 Core Purpose

The Core Loop
ACTION
Actual Action
of the
Mechanic
REWARD
Reward for
Executing the
Action
TRIGGER
Event that
Triggers the
Action

Behavior Psychology
Volition: The power of
using one's will.
Operant Conditioning:
A type of learning
where behavior, or
volition is controlled
by consequences. B.F. Skinner

Reward Ratios
Frequency Effectiveness
Constant (Fixed) Poor
Intermittent (Fixed) Good
Random (Variable) Best

Does a fixed reward or a variable reward
produce the highest rate of activity?

Does Behavioral Conditioning Work On
People?

Reward Ratios In Games
A player must shoot down approximately 20
enemy fighters to gain an extra ship, but the
precise number is randomly generated each
time.

Reinforcement with Extrinsic
Rewards
 Primary Conditioners:
A reward that satisfies
a biological need.
 Secondary
Conditioners: A
reward associated
with a primary reward.

What Would Be A Primary And Secondary
Conditioner In Games?

Chain Schedule
What happens if there are multiple stages to
the reward?
Example: Kill 10 orcs and take each one’s loot
before entering the dragon’s cave, where it is
guarding a treasure.

Extinction
What happens if you stop providing the
reward?
Example: The player suddenly stops
receiving gold for killing orcs.

Avoidance
What happens if the reward is to keep bad
things from happening?
 Ultima Online: Visit house to prevent
decay.
 Farmville: Harvest crops before they wither.

Behavioral Contrast
What happens if expectations change?
 Player receives 1 gold coin for killing orcs, and
then later starts receiving 10 gold cold coins.
 Reward is then switched back from 10 gold coins
to 1 gold coin.

Mechanics and Structure Elements
Mechanics:
 Allowed by Procedures
 Follow Rules
 Consume or Produce Resources
 Impeded by Challenge
 Occur within Boundaries

Procedures
 Starting Action
 Progression of Action
 Special Actions
 Resolving Actions

Resources “Fuel” And Are Produced By
Actions

Movement
The action of moving game elements within
the game boundaries.

Why Designers Use Movement
 Game World Navigation
 Progress Indicator
 Dexterity-Based Actions
 Puzzle Solving
 Supports Race, Capture, Stealth, Herd,
Delivery, Traverse, Collection goals

Movement Design Characteristics
