Developing applications and games in Unity engine - Matej Jariabka, Rudolf Kajan - gamifi.cc

  1. 1. Developing applications & games in Unity engine Matej Jariabka co-founder of gamifi.cc
  2. 2. 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
  3. 3. 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
  4. 4. 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
  5. 5. Platforms supported by Unity • Consoles current-gen & next-gen • Mobile • Desktop
  6. 6. Platforms supported by Unity
  7. 7. Unity vs Kickstarter 1/2 Is Unity popular on Kickstarter? 40% of games in TOP15 Most Funded Video Games use Unity *As of 11/2013
  8. 8. Unity vs Kickstarter 2/2 How much $USD Unity games raised on Kickstarter.com? $16 403 255 6/15 games in TOP15 Most Funded Video Games *As of 11/2013
  9. 9. 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.
  10. 10. Alternatives • CryEngine – Several options for licensing – Visually rich & powerful • Unreal Engine – Flexible for game genres, multiplatform – Free, or 25% from profits over $50k
  11. 11. Why Unity - PROS • • • • • Unity if free (low/limited price) Multiplatform tool Support and ongoing development of new feature Asset store, plugins Indie standard
  12. 12. Why Unity - CONS • Unity Pro is not free • Requires skills! (coding) • Will require customization
  13. 13. Unity for non-developers Prototyping Build Test Deploy • Easily integrate non-developing people into the flow • Less and less complex work for dev team
  14. 14. Prototyping Quick feedback • Does it look good? • Is it working as expected? • Does it fit to the concept?
  15. 15. Test 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.
  16. 16. Deploy • Publish on Store / Marketplace • Texts • PR & Marketing
  17. 17. 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)
  18. 18. 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

  22. 22. Smart Multipurpose Interactive Learning Environment • With visually impaired players in mind • Educational aspects • GarageGames • Torque
  23. 23. #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
  24. 24. #2 - Iterate Small Idea • “Like <insert AAA title name>, but better!” • Multi-platform cloud-based MMORPG with social aspects #3 - Stay Visible

  32. 32. The Great Wobo Escape
  33. 33. Fast Prototyping • Quick Pivots • Test ideas – TuDee, then develop your tools (NOT engine first) • TEST ON PEOPLE!!! (HCI, video recs, notes) - they will do stuff you do not expect!
  34. 34. Unity • • • • • • • • Extendable Editor Browser & Inspector Scene Hierarchy Mecanim Shuriken Scripting Networking Asset Store
  35. 35. First Iteration of Basic Components 03/2013 07/2013
  36. 36. Current Consumer Mobiles • • What you can reasonably expect to run on current consumer mobiles: Lightmapped static geometry. But beware of: • • • • Animated characters, even with fancy shaders! But beware of: • • Overdraw, or, lots of layers drawn on top of eachother. Particle effects. But beware of: • • • Massive crowds or high-poly characters 2D games with sprites. But beware of: • • Using a lot of alpha-test shaders Bumpmapping, especially using built-in shaders. High polygon count 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
  37. 37. 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.
  38. 38. Tools We Use and Love • • • • • Unity3d Blender GIMP Zbrush BlackInk • • • • TuDee VS + UnityVS Serializer GameAnalytics
  39. 39. Tools We Use and Love • • • • • Unity3d Blender GIMP Zbrush BlackInk • • • • TuDee VS + UnityVS Serializer GameAnalytics
  40. 40. Level Design • • • • Idea – Level Beat Chart TuDee / Excel  Generated Prototype Scene in Unity Parallel Testing / Adjustments – Actors • State Machines, FSM, experimental FFSM, INDIE RAIN! – Triggers
