- 1. Minecraft and Scala: Creating a DSL to enable Kids to Create Mods Paulo “Jcranky” Siqueira Paulo.siqueira@gmail.com / @jcranky
- 2. @JCranky Who am I ? Developer (Scala, Java)
- 3. @JCranky Who am I ? Gamer Minecraft and Other Indie Games
- 4. @JCranky Who am I ? Musician Wannabe!
- 5. @JCranky Who I work for TecSinapse Car Dealers Research and Innovation
- 7. @JCranky Setting the Scene What is Minecraft What Are Minecraft Mods What Are Kids
- 8. @JCranky Then... Easyforger: the DSL Pending challenges summary
- 9. @JCranky What is Minecraft Open World Game DO ... … Whatever
- 10. @JCranky What is Minecraft Single Player multiplayer
- 11. @JCranky What is Minecraft Client – Server Architecture Written in Java … go figure
- 12. @JCranky Single Player Internal Server Very performatic (unless recording or on a bad/old machine)
- 13. Starting a new Game
- 14. Barbecue Machine
- 15. @JCranky Multi player Client: Player Machine Server: Anywhere, Holds the Business Logic
- 16. Craftbot Server
- 17. Some Multi Player fight
- 20. @JCranky What are Mods Community Mods to the rescue!
- 21. @JCranky What are Mods No Official Api (Being developed for a While...) … in theory
- 22. @JCranky What are Mods Community to Rescue (again)! Client-Server API Mapping Minecraft CODE Decompilation
- 23. @JCranky Decompilation Easy: Its Java! Quite unpleasant Identifiers though...
- 24. Identifiers ...
- 25. @JCranky Modding Alternatives Server-Side Modifications (aka server plugins) Client Mods (which also goes on the server...)
- 26. @JCranky Server Plugins Several Options (all including said SERVER API Mapping) Bukkit Canary Spigotmc etc
- 28. Chicken Shooter
- 29. @JCranky Good! Any client can join Nothing to be Installed
- 30. @JCranky Bad! Can't add new Stuff (Blocks, Entities etc) Just change/Control what's already there
- 31. @JCranky Client Mods: Forge Minecraft Forge Main (only?) option Already includes the Decompilation (part of the build setup)
- 32. @JCranky Demo: the difference A Normal Client A Minecraft Forge Client
- 33. @JCranky Good! Can do just about anything
- 34. @JCranky Bad! For multi Player... Mods have To be installed in the server as well
- 35. @JCranky Bad! The installation can be complex
- 36. @JCranky Bad - instalation No standards Jar jugling
- 37. PixelMon Craft
- 38. Mad pack
- 41. @JCranky But How? Pre-configured eclipse With forge and MCP
- 42. @JCranky But How? Kids modify something and Run the game from the IDE
- 43. @JCranky But How? Sounds simple enough ...
- 44. @JCranky All well... But lets do better!
- 45. @JCranky Why not... Scala? Its the JVM After all!
- 48. @JCranky A Dsl ! That's Exactly what DSLs Are good for!
- 49. @JCranky Quickly: DSL Types Internal: Written and interpreted in the laNguage
- 50. @JCranky Quickly: DSL Types External: uses parsers and other tools syntax freedom
- 51. @JCranky Our decision Go internal! Its simpler and Scala is amazing for that!
- 52. @JCranky Our decision 5 minutes (from scala.concurrent.duration)
- 53. @JCranky Our decision Auto complete from IDEs is available out of the box
- 54. @JCranky Enter EasyForger A DSL for writing minecraft Mods (on top of minecraft forge)
- 55. @JCranky Enter EasyForger Supports simple modifications (with lots more to come!)
- 56. @JCranky Next, lets see: What can it do? How is it done?
- 63. @JCranky How? Lots and Lots of Experimentation Target: what “feels right”?
- 64. @JCranky How? Write what I want Implement and make it work
- 66. @JCranky Implementation Guess what... Lots of implicits!
- 67. @JCranky Implementation Small methods Case classes and use of copy
- 70. @JCranky The sin Hard to avoid some side effects
- 72. @JCranky Where are we? Not tested in the field yet =(
- 73. @JCranky Where are We? Target: make it really easy!
- 74. @JCranky Where are We? Tried Last October Environment not ready
- 75. @JCranky Where are we? Lots to do and fix Help is welcome!
- 76. @JCranky Problems and ideas Setup Macros Mod Installation
- 77. @JCranky Problems and ideas Behavior mods Auto Complete excess
- 78. @JCranky Setup Make it easy to setup! No downloads if possible!
- 79. @JCranky Setup Minecraft Forge Gradle Build does a Lot! (plus lots of dependencies downloaded)
- 81. @JCranky Macros Perhaps good for simpler constructs?
- 82. @JCranky Macros Don't forget about Auto complete!
- 83. @JCranky Mod Installation Process EasyForger is a mod itself
- 84. @JCranky Mod Installation Process Separate that and perhaps solve the setup problem...
- 85. @JCranky Custom Behavior support Experimental Not happy with the DSL yet
- 86. @JCranky Custom skeleton behavior Code: Custom Skeleton
- 87. @JCranky Auto Complete Excess Predef (etc) stuff is useless In the auto complete box (for the dsl)
- 88. @JCranky Auto Complete Excess Confusing for beginners
- 90. @JCranky In time... Why only kids?
- 91. @JCranky In time... Why only beginners?
- 92. In time...
- 94. @JCranky Modding minecraft == fun.2
- 95. @JCranky Enabling kids to do it == Fun.3
- 99. @JCranky Acks TecSinapse For allowing me to come (even though I just started there ;))
- 100. @JCranky Acks You! For listening... And for future contributions! ;)
- 101. @JCranky Questions ?! Throw them at me! If it pleases you...
