How can you do in minecraft that if you enter / start you get items?
With a plug-in or a modification.
With which
I don't know, Google helps.
Or with a function. Functions can be used to string commands together. Then you can simply combine the commands, for example: / give @a iron_sword… You then call this function start. When you have created the function, you have to enter: / function start in Chat.
We don't know what you want to get with / start, just search for it on the Internet or program it yourself.
With a plugin.
One that gives you at / Start Items is not known to me. Probably not there either.
But there are some you get at / kit starter a starter kit (set by you as server owner). Or even automatically the first time you join.
Just search for "Kit Plugin". I think this is quite good: https://dev.bukkit.org/...s/easykits
He wanted / start, not / function start.
That's right, but as far as I know, it doesn't work, and if it does, it is much more complex, so I thought I would simply offer him an alternative. Nevertheless, you are actually right.
The only question is whether Vanilla has enough permission variability to only allow one function.
