Networking Options

• Built in• Smart Fox• Photon• Electroserver 5

Aquiris Game Studio | Amilton Diesel, Maurício Longoni, Raphael Baldi

Built in Solution

• Pros• Easy control over the network• Network views watching objects• Simple RPC implementation• Is already in Unity• We had previous experience with the system

• Cons• Unity only server• Runs only on Windows and Mac• Not made for thousands of players per instance• Good for local hosted games, not for 2k+ players in a single server


Built in networking is not an option

What we chose?

• ElectroServer 5• Tech Support• Proven with previous Flash games• Great admin tools• Runs under linux


11 09/29/11

Artwork Challenges

• Complex Structure• Lightweight Graphics• Small Packages


12 09/29/11

Large Spaces vs Unique Artwork


13 09/29/11

Basemesh

• Max 50k triangles• Max 30 objects• Max 3k triangles per object


14 09/29/11

Tileable ~ 50% Coverage


15 09/29/11

Trims ~ 25% Coverage


16 09/29/11

Unique ~ 25% Coverage


17 09/29/11

Graphics Tweaking

• From Geforce 6 series, to all cards.• Saving Presets• Auto Benchmark

Technical Overview

• Asset pipeline• Game design flow• User data• Networking• Publisher integration


19 09/29/11

Asset Pipeline

• Automatic import tools• Build tools• Memory control• Loading and unloading assets on the

fly


20 09/29/11

Automatic import tools

• Tons of items/weapons• Textures• Animations• Custom data

• Manual setup is bug prone• Asset pre and post processing

Build Tools

• Asset bundles• Build time• Editor tools


24 09/29/11

Memory Control

• Loading assets• Know what you’re not using• Unload unneeded stuff• Asset bundles for maps may use up to 200

MB of Ram!

Networking Overview

• Architecture• Topology• Lobby and match system• Event driven development• How to exchange data between client

and server?


33 09/29/11

Networking Architecture

• Client - server• Semi authoritative server• 100+ matches per server instance• From 8 to 16 players per match• Tons of messages• Lightweight server solution

Avoiding Tedious Paperwork


42 09/29/11

Avoiding Tedious Paperwork II

• Continuous integration.• Automated Deployment.• Eliminate code when you can. • Democratize content creation.


43 09/29/11

Continuous Integration

• Find code problems more quickly.• Reduce “works on my machine”

problems.


44 09/29/11

Automated Deployment

• CI can drive automated deployment.• Forces you to have reliable

build/deploy methods.• Do it now. Once you have real players

it just becomes more difficult.


45 09/29/11

Code Is The Enemy• Please don’t hurt me.

Protocol Generation II

• Protocol efficiency improvements can be made globally with low cost.

• Developers get strongly typed messages.• Model complex data with little effort.• Support clients across many languages /

platforms.


48 09/29/11

Data Is The Enemy• I lied earlier about code being the enemy.


49 09/29/11

Dealing with Data: Tools

• Tool dev can easily absorb 30% of dev time.

• “Tools will make or break an MMO.”

Not so democratized


51 09/29/11 Electrotank | Jonathan Wagner

Better!

52 09/29/11

Let tools do their own thinking

• Give your entities metadata.• Give the metadata to the tools.• General purpose data entry tools can write

themselves.• Spend time on specialized operations tools.• Very low risk of SkyNet.
