The document discusses the creation of Easyforger, a domain-specific language (DSL) developed to help kids create mods for Minecraft using Scala. It highlights the challenges and differences between community mods, server-side modifications, and client mods, emphasizing the importance of simplifying the modding process for beginners. The presentation outlines features of Easyforger, its implementation, and future goals to enhance user experience and accessibility in Minecraft modding.

- 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...
