I hope this guide will help you get known with coding. New threads will come soon concerning coding a server.
Algelier.

 

Not yet, I still have to gain knowledge in:

• Instances
• Scoreboards
• Tab lists
• Coin system (API)
• Stats system

Other than that I'm able to code:

• Titles
• Kits
• Basic/custom guns
• Grenades
• Custom crafts
• Custom NPC
• Custom Mobs
• Custom signs
• Custom Spawners
• GUI
• Automatic broadcasts
• Team system
• Double jump
• ChatGuard
• Custom firework
• Blood particles
• Custom items (such as a switcher etc.)
• Hub system
• Timers
• UHCRun
• Skywars
• Custom regeneration
• Custom teleportations
• Custom block drops
• Borders
• BuildBattle (arenas, themes)
• Game states
• Custom explosions
• A snake game

 

This is just a list, not a tutorial to code a server. And as I said at the end of this thread more threads are to come.
