You right click his chest, in the chest you select what you want like "Stand still" "Follow me" and Patrolling: "Manual - automatic"

• When the player clicks follow me (easiest option) the guard stores a player object and follows around the player until he dies or until the player changes it in its gui.

• When the player clicks "Stand still" an item is given into his held item slot and the player is asked to select a spot which should be guarded

• And when the player clicks "Patrolling manual" this item is also rendered and he is asked to select a route with left click and finish the selection with right click"

• The task is stored in the building but on new hire or death the follow me task will be reset.

Guards should notice the player about their low health.
Guards should notify their location on death.
GUI option which lets guards retrieve on low health -> make him retrieve slowly.
Guard gets stronger the lower his health is.

What happens when Player dies outside the colony with a guard following.. do they warp back to the colony (preferred?)

were going to have to make him follow outside of the colony boundary at some point..

Personally I would make it an indefinite distance, and he never tries to return to his chest if he is outside the colony boundary..
