turtles-own

turtles-own [var1 ...]-own [var1 ...]

The turtles-own keyword, like the globals, breed, -own, and patches-own keywords, can only be used at the beginning of a program, before any function definitions. It defines the variables belonging to each turtle.

If you specify a breed instead of "turtles", only turtles of that breed have the listed variables. (More than one turtle breed may list the same variable.)

breed [cats cat ]
breed [dogs dog]
breed [hamsters hamster]
turtles-own [eyes legs]   ;; applies to all breeds
cats-own [fur kittens]
hamsters-own [fur cage]
dogs-own [hair puppies]

See also globals, patches-own, breed, -own.
