Requires the library mod Collective.

     This mod is part of The Vanilla Experience.
GUI Followers is a client-side mod which shows a list of all tamed non-sitting following mobs around the player. By default it also shows the health of the follower as a percentage, and how many blocks it is away from the player. Fully configurable! You'll never accidentally leave your wolf buddy behind.


Configurable: ( how do I configure? )
followerListHeaderFormat (default = "Followers:"): The header text above the follower list.

showFollowerHealth (default = true): If enabled, shows the follower's health in the GUI list.
followerHealthFormat (default = ": <health>%"): The format of the health string in the GUI. <health> will be replaced by the percentage of total health.
showFollowerDistance (default = true): If enabled, shows the follower's distance in blocks to the player in the GUI list.
followerDistanceFormat (default = " (<distance> blocks): The format of the distance string in the GUI. <distance> will be replaced by distance in blocks.

distanceToCheckForFollowersAround (default = 50, min -1, max 300): The distance in blocks around the player where the mod checks for tamed, non-sitting followers to add to the list. A value of -1 disables this feature.
timeBetweenChecksInSeconds (default = 2, min 0, max 3600): The time in seconds in between checking for tamed, non-sitting followers around the player.

followerListPositionIsLeft (default = true): Places the follower list on the left.
followerListPositionIsCenter (default = false): Places the follower list in the middle.
followerListPositionIsRight (default = false): Places the follower list on the right.

followerListHeightOffset (default = 20, min 0, max 3000): The vertical offset (y coord) for the follower list. This determines how far down the list should be on the screen. Can be changed to prevent GUIs from overlapping.

RGB_R (default = 255, min 0, max 255): The red RGB value for the text.
RGB_G (default = 255, min 0, max 255): The green RGB value for the text.
RGB_B (default = 255, min 0, max 255): The blue RGB value for the text.

The wolf named buddy shown in the GUI:


The wolf buddy is currently at 85% health. I did feel a little bad about testing this.


Sitting entities will not be added to the follower list.


Long distances are supported.
