is there a command "kill a player"?

I know you meant /kill and no.

entity.call ("suicide")

Only the administrator can write to the chat to kill the player)

I believe you can use a check for XUID and then if it's true do the entity.call("suicide"), if false return something else like entity.call("iprintlnbold", "You do not have access to this command.")

 

Also this command kills you. You need to figure out a way to inflict this on the player. Or look at the infinityscript source code and look at eHealth stuffz. (It's in testscript.cs)

Use Alteradmin plugin and a server side plugin to process the commands.
