This is a spawn attachment for servers. It allows new players to gain a starter kit but will teleport them away so they cannot gain a second kit (unless you decide to teleport them back if it is stolen or something). To change it all you have to do is reconfigure the command blocks which you will have to do for the teleport command block (otherwise they could end up stuck in a wall).

The give command blocks can be modified as so:

give @p[m=< required game mode>]

The gamemode command blocks are:

gamemode l @p[m=]

The teleport command is:

tp @p



PLEASE comment below problems or praise I want to know. I would be happy to answer any queries you could possibly have.

Additional Notes

I will be trying to make more attachments for spawn so keep an eye out.
