Control e.g. At Minecraft airport?

How can you make a check that only opens the entrance when you have emptied your inventory. You have to put the things in the inventory into a chest lore and the things are scanned and checked whether there are weapons in them. How do you do that?

Definitely not with a CMD block.

For this you need plugins

I haven't written any of it 📝

You asked how you can achieve your desired function.

Oh!

Why don't you look at TJC for information on how he did it?

Because I don't see anything in the redstone bustle!

Then kindly ask him if he can provide you with all of this.

How?

You test by command whether something is in the inventory. Search the Internet for the command.

I'm aware

I don't know TJC. Youtube? Write to server? No idea. Find a way to reach him
