die 1.0

die

The turtle or link dies.

if xcor > 20 [ die ]
;; all turtles with xcor greater than 20 die
ask links with [color = blue] [ die ]
;; all the blue links will die

A dead agent ceases to exist. The effects of this include:

• The agent will not execute any further code. So if you write ask turtles [ die print "last words?" ], no last words will be printed, because the turtles are already dead before they have a chance to print anything.
• The agent will disappear from any agentsets it was in, reducing the size of those agentsets by one.
• Any variable that was storing the agent will now instead have nobody in it. So for example let x one-of turtles ask x [ die ] print x prints nobody.
• If the dead agent was a turtle, every link connected to it also dies.
• If the observer was watching or following the agent, the observer’s perspective resets, as if reset-perspectivehad been run.
