1. Why you need game engine What actually is game engine, and why Unity is so successful ;-)

2. Disclaimer The views expressed here are my personal views and do not necessarily reflect the thoughts, opinions, intentions, plans or strategies of Unity

3. What is game engine Your call

4. What is game engine Let me guess: Rendering Physics even more stuff Technology in short

5. What is game engine Welcome to the real world YOU ARE WRONG

6. What is game engine When talking about technology you forget: Not so cool-looking technology most of people thinks engine=rendering How to get meshes/textures/... in there How much time to wait if texture was changed How do you create levels lots more

7. What is game engine Technology Tools Infrastructure well, nothing lives in isolation how well pieces fit

8. What is Technology Multiplatform unless platform holder pays you unless you don't need money unless you are doing smth impossible else or you are wrong or platform holder will pay you

9. What is Technology Example: Rendering if you didn't try consoles - you will fail if you didn't try gl/dx/gles you will fail if you don't know your hardware you will fail if you don't read RTR you will fail if you don't know/have constraints you will fail you need more? ;-)

10. What is Technology Hidden Technology What about: leaderboards achievements saving/loading, checkpoints etc multiplayer quick loading updating and DLC you name it

11. What is Technology You don't need it if you create old-school lines/tetris you need reality check You don't need all of this if you are careful about constraints You will need this as you try to scale down from mac to ipad

12. What is Technology We'll be back when talking about infrastructure There is more hidden in there Far more important then you think

13. What are Tools You will need to create your levels even for something like zuma time-management non-standard match3 you name it

14. What are Tools You will need to tweak lots of stuff Asset Pipeline conditioning params Materials Object Properties And do it fast and see the results

15. What are Tools You will need a lot of stuff Managing your content where was that texture/shader for this tree Creating additional data achievements localization Reusing stuff i want this tree in another level You name it

16. What are Tools You don't need it if you use xml/json/inis - just type here you need sanity check if you hate artists/designers if you have all the time on earth You don't need all this Until you need it yesterday

17. What is Infrastructure How does it all fit together iteration time interoperability workflow fit unification everything else the "feel"

18. What is Infrastructure Iteration time You change something texture mesh location script object params (e.g. movement speed) How much time is needed to see it in game This might be the difference between shipping in one month and in 3 months less-polished

19. What is Infrastructure Interoperability How well parts works with each other DCC tool plugins Asset importing and Level editing Conflicts Coupling changing drawed mesh params shouldn't result in physics fidling changing texture on tree shouldn't result in whole world re-import/rebuild

20. What is Infrastructure workflow fit artists vs programmers sound engineer might look differently unification how much tools/steps is needed for object draw params physics params scripting

21. Still want to create in-house? Create engine in-house is awesome! if you have cool experienced programmers if you have up-front time if you need specific technology you can argue about "specific" part if you can do it better if it is your first game ever - you can't if you want to know how engines works For hobbyist learning project - awesome exp

22. Still want to create in-house? For AAA game - unsolved problem diff credits for UE3 game and in-house tech big games have source licence ;-)

23. Still want to create in-house? For smaller games - even more interesting ios: $0.99 meaning: you need to be *very* fast ios vs android fragmentation even on ios on android - almost desktop-like driver-bugs and harware "features"

24. Still want to create in-house? generally mobile they *are* underpowered unless you know how to use hw welcome back FFP tricks or earlier-days shader oprimizations welcome back assembly

25. Still want to create in-house? generally mobile a lot of stuff to integrate different platform api different features achievements leaderboards in-game purchases accelerometer/gyroscope etc

26. Still want to create in-house? More power to you (really)

27. Unity Well, as i am working in Unity... ;-) Was created to help inexperienced teams The very first customer was team of 2 artists yes, they succeeded ;-) The idea is to open gamedev to masses Lots of platforms mac/win/web/ios/android/x360/ps3/others (NDA) Lots of guidance

28. Unity Programming: JavaScript, Boo, C# Thinking about others Art FBX meaning almost everything Autodesk, Modo, Blender, Sketchup, Cheetah and some more [too much to remember] PSD, JPG, PNG, TGA, TIFF, and more

29. Unity Operates on high level Components MeshRenderer, MeshCollider, etc Assets Mesh, Texture, Sound you will get this automagically

30. Unity Prefabs You can save object at full and reuse with components meaning everything Scenes Level editing Meaning one place to place objects and edit props

31. Unity Multiplatform: Select platform and build That's all almost ;-)

32. Unity Materials/Shaders All power to you preset shaders you can write your own

33. Unity Unity Editor is written on C# mostly meaning we expose almost everything meaning - write your own tools if needed meaning - lots of plugins are already there

34. Unity in-Editor Play button play your game ;-) while having all Editor power right here change texture and see this change script, wait for compile, and see that

35. Unity Runtime we did lots of hard-lifting skinning on NEON? Been there done that ;-) driver bugs on XXX? Ah yes, we have workaround once again - lots exposed to c# plugins: lots

36. Unity Bells & whistles Beast lightmapping? check Beast point clouds? working in it Umbra occlusion? check cool LOD system? almost there profiling? check run on target hw, collect data in Editor random stuff? you will be surprised ;-)

37. Questions?
