What it takes to make a game? Asset pipeline and game engine

Cooperation ● Each aspects supports the other ones in one way or the other ● Tasks are divided up so that their execution can be parallelized ● Maximize output

Visual development processes in games and movies ● Getting more similar and similar as time goes on ○ Asset pipelines are getting closer (physical shading for example) ○ Game development still has extra steps and considerations. ● Both for good and bad...

Environment ● Design ● Art ○ Story/Idea ○ Story/Idea ○ Sketch ○ Gather reference ○ White/grey box ○ Concept art creation ○ Gameplay scripting ○ Basic shape modeling ○ Maintaining working state ○ Final art creation as art comes in ■ Model (high and) low poly ■ (Bake) ○ Fix bugs ■ Unwrap ■ Texture and shade ○ Import assets ○ Add lighting, effects, ambient sounds etc... ○ Maintain working state as gameplay evolves ○ Fix bugs

Characters Character development cycle example from Team Fortress 2: 1. Character silhouette 2. Interior shapes 3. Model sheet 4. 3D Model 5. Character Skin 6. Final Character in game

Animation ● Very time consuming ● Hand animation versus motion capture ● Canned versus procedural

Vertical slice ● Small polished section of game ● All aspects polished ● Helps to find problems earlier ● A chance for all departments to work together ● Bechmark for the rest of the game ● Potential time sync

Game engines ● Game engine is a set of software responsible for the game mechanics ● Runtime vs Tools

Layers

Hardware ● Desktop ○ A lot of configurations to handle ● Mobile / embedded ○ Still growing market ● Dedicated ○ Military simulators ● Name some differences!

Examples ● Input ○ touchscreen vs mouse vs gamepad vs keyboard ● Screen resolution ○ mobile devices vs desktop ■ 640x960 vs 4096x2160 ● Memory

Driver management ● Driver - Low level software component ● Driver operates as a delegate between upper layers and hardware

Operating system ● Win / OSX / Linux ● Embedded ○ Weird ones… In the bus ○ Mobile ■ Android ■ iOS ■ Windows Phone ■ BB, Tizen?

Engine core ● Support for components ○ Scripting ○ Graphics component ○ Input / Output component ● Initialize behaviour between components

Resource manager ● Getting data to the game ○ Asset manager ■ Loading data from HDD, Discs ○ Streaming system ■ Open world ● Open World vs Indoor

Rainbow Six: Siege

Middleware (Third Party SDKs) ● Nvidia PhysX ● Havok Animation ● Boost C++ ● Anything else?

SDK // Move sprite to position 50,10 in 2 seconds. auto moveTo = MoveTo::create(2, Vec2(50, 10)); mySprite1->runAction(moveTo); // trigger when you push down listener1->onTouchBegan = [](Touch* touch, Event* event){ // your code return true ; // if you are consuming it };

How? ● How to make a game ○ world ○ logic ○ graphics ○ sound ○ test! ○ Maintenance
