in Unity engine

Introducing gamifi.cc

• Indie studio from Brno, CZ: David Jozefov, Rudolf Kajan, Matej Jariabka, Martin Wilczak

• Experience with games for Win, XBOX360, Windows Phone

• FireFighters: Whatever It Takes! (world finals of Microsoft Imagine Cup 2011 – 3th place in Game Design category)

• Yggdrasil: The Tree of Life (world finals of Microsoft Imagine Cup 2012 – 6th place in Game Design category)

• The Great Wobo Escape multiplatform 2.5D action puzzle platformer, in development since 01/2013

How we discovered Unity

• We have a game, we don’t have an engine

• What is a trend, what others use?

• Platforms!

• No re-inventing the wheel!

• Thinking 5+ years in advance

Why is Unity a clear choice for us

• Easy multiplatform development minimizes risks!

• Easy to use

• We can create what we need (editor)

• Minimum training required

Platforms supported by Unity

• Consoles current-gen & next-gen

• Mobile

• Desktop

How to choose a game engine

• Don’t start to make a game by creating an engine!

• Know your limits and goals

• Make choice in line with your business model

• Choose for a game type - FPS, MMO, Casual

• Don’t be afraid to invest (a little)

– tools, support, licence type, modules, etc.

Alternatives

• CryEngine

– Several options for licensing

– Visually rich & powerful

• Unreal Engine

– Flexible for game genres, multiplatform

– Free, or 25% from profits over $50k

Why Unity - PROS

• Unity if free (low/limited price)

• Multiplatform tool

• Support and ongoing development of new feature

• Asset store, plugins

• Indie standard

Why Unity - CONS

• Unity Pro is not free

• Requires skills! (coding)

• Will require customization

Unity for non-developers

• Easily integrate non-developing people into the flow

• Less and less complex work for dev team

Prototyping Build Test Deploy

Quick feedback

• Does it look good?

• Is it working as expected?

• Does it fit to the concept?

Prototyping

Testing is independent on Dev team

1. In Unity: File -> Build & Run

2. Publish through Unity Web Player, send .apk, .etc.

3. Testing, bug reports, etc.

Test

• Publish on Store / Marketplace

• Texts

• PR & Marketing

Deploy

Unity Web Player

• Share a whole game through just one URL

• Win / Mac OS + any browser is required - universal

• Unity: File -> Build & Run -> Web Player

• Dropbox \ Public directory (copy public link)

Unity Hardware Statistics

• Useful for setting a minimal HW requirements

• Simple but free, anonymous stats: OS version, GPU,

CPU, memory size, display size, device manufacturer

• For Web player, Mobile, Editor

• stats.unity3d.com

Smart Multipurpose Interactive Learning Environment

• With visually impaired

players in mind

• Educational aspects

• GarageGames

• Torque

#1 - Use Tools!

• Time is better used making a polished game

• Easy to ramp up new people

• Moving between projects is easier (2D/3D game switch)

• Lots of available tools (Unity)

• BUILD GAME, NOT TECH!

• Reinventing the wheel is a trap – 75% done easily, rest super-expensive

#2 - Iterate Small Idea

• “Like <insert AAA title name>, but better!”

• Multi-platform cloud-based MMORPG with social

aspects

#3 - Stay Visible

XNA

• Lots of o-o-b functionality

• Documentation

• Community content

• VS integration

• Just MS platforms

• Future Support

• TEST ON PEOPLE!!!

First Iteration of Basic Components

Current Consumer Mobiles

• What you can reasonably expect to run on current consumer mobiles:

• Lightmapped static geometry. But beware of: • Using a lot of alpha-test shaders

• Bumpmapping, especially using built-in shaders.

• High polygon count

• Animated characters, even with fancy shaders! But beware of: • Massive crowds or high-poly characters

• 2D games with sprites. But beware of: • Overdraw, or, lots of layers drawn on top of eachother.

• Particle effects. But beware of: • High density on large particles. (Lots of particles drawn on top of each other. This is another overdraw situation)

• Ridiculous numbers of particles, or particle colliders.

• Physics. But beware of: • Mesh colliders.

• Lots of active bodies

Current Consumer Mobiles

• What you CANNOT reasonably expect to run on current consumer mobiles:

• Fullscreen screen image effects like glow and depth of field.

• Dynamic per-pixel lighting (multiple lights marked Important and not baked into the lightmap) • Every affected object is drawn an additional time for every dynamic

light you use, and this gets slow quickly.

• Real time shadows on everything • Unity 4 offers native support for real time shadows on mobile

platforms, but their use must be very judicious, and likely limited to higher-end devices.

Tools We Use and Love

• Unity3d

• Blender

• GIMP

• Zbrush

• BlackInk

• TuDee

• VS + UnityVS

• Serializer

• GameAnalytics

Level Design

• Idea – Level Beat Chart

• Generated Prototype Scene in Unity

• Parallel Testing / Adjustments

– Actors

• State Machines, FSM, experimental FFSM, INDIE RAIN!

– Triggers

Batching

Rule of thumb: don’t use more then a few hundred draw calls per frame on mobiles or a few thousand

on desktops for current hardware.
