All the maps must be in the root folder (where the other worlds are in)

/maps

This command shows you in a customizable menu all the maps you created in the maps.yml file.

/mapquit

This command let you quit the current queue or the map you are currently playing in.

maps.yml

This file can be edited following certain rules:

• You can add as many worlds you want but each must have a different name.
• You MUST write the amount of minPlayers and maxPlayers. Both must be higher than 0.
• You can OPTIONALLY add a Description field which will be showed in the menu.
• You can OPTIONALLY add a Material field which will be the actual material of the item representing the map in the menu. Default to PAPER.
• You can OPTIONALLY add a Data field which will be the customModelData id in case you want to change the texture of the map item in the menu. Default to 1.

If a map doesn't follow the rules it's not going to be displayed in the menu.



menu.yml

This file can be edited for a full control over the maps menu.

• PreviousPage: This holds the material and the customModelData of the Previous Page item. Displayed when there is a previous page.
• NoPreviousPage: The same but it is displayed when there isn't a previous page.
• NextPage: This holds the material and the customModelData of the Next Page item. Displayed when there is a previous page.
• NoNextPage: The same but it is displayed when there isn't a next page.
  
• Border: It is the item that creates the first line border.

Default Avaiable Page Material: EMERALD_BLOCK
Default Non Avaiable Page Material: REDSTONE_BLOCK
Both Default CustomModelData: 1
Default Border Material: GLASS_PANE

I personally suggest choosing a material then creating textures for other customModelData displaying an X for non avaiable page and left left/right arrows for previous and next page, so the menu would be way cleaner.
