Easy way to execute remote admin commands?

So I'm finishing up my survival games map, adding final touches and such, but... I need an easy way to execute remote admin commands, like setting my own gamemode to creative, starting the game, or resetting the game. Right now, I am using a tellraw command on a clock, so I can easily and quickly click on the options in the chat.

Here is my current setup:

Often times, though, it spams the chat and gets in the way... Is there any way to play in the game, and be able to control the game remotely without using the current setup? Or maybe have the tellraw occupy one line, always on the bottom of the chat?

Solution 1:

You can have a book that in which you can execute commands. I don't fully understand the detailed method of creating books with commands but there's a very simple tool on minecraftjson.com.

For example, here's a simple book to set your gamemode to creative or survival:

/give @p written_book 1 0 {pages:["[\"\",{\"text\":\"Hello, \"},{\"selector\":\"@p\"},{\"text\":\"!\n\n\"},{\"text\":\"Gamemode:\n - \"},{\"text\":\"Creative\n\",\"color\":\"blue\",\"underlined\":\"true\",\"clickEvent\":{\"action\":\"run_command\",\"value\":\"/gamemode 1 @p\"}},{\"text\":\" - \",\"color\":\"none\",\"underlined\":\"false\"},{\"text\":\"Survival\",\"color\":\"blue\",\"underlined\":\"true\",\"clickEvent\":{\"action\":\"run_command\",\"value\":\"/gamemode 0 @p\"}}]"],title:Book,author:TellrawGenerator}

Alternatively you can have triggers you can type to execute a series of commands or just a trigger to bring up the menu you are using right now.
