Hey there!
I have made a website for all of you!
You can generate easly a new command, e.g. when a player open his inventory they will get a stone or summon an item!
That would be really great for Adventuremaps or Minigames! Or to troll your friends.. all can happen :D

There will come more events and commands (like Tellraw, Title, Spreadplayers..) next time.
After you click on "Create!" there will create a OneCommandBlock with your options you only must copy and paste the command in an CommandBlock(!) and power them with an redstoneblock. Thats all - easy, mh?! :D




Please leave a comment with more ideas for me! :D

Greets,
Kai! ;)
