The breed can be set dynamically ask turtle 1
NETLOGO BREEDS PATCH
ask patch 17 13 And this will paint the field with coordinates (17,13) in soft pink.
NETLOGO BREEDS CODE
Executing commands in the context of agents is the main mechanism for working with them.Īsk turtles This code will ask all the turtles to take a step forward. The agent is “first class value” if desired, it can be stored in a variable, but this is rarely required.Īn agent or set of agents can be the context for a team. The turtles are created with the create-turtles command (with the argument the number of turtles to be created), and then found by the turtle index function. There is also a special agent - the observer. A new breed is created by the team breed where ninja is the name of the breed, and ninjas is the name of the collection that brings together all the agents of this breed. Representatives of the same breed are also combined into a set. Agents of the same type are combined into the corresponding set (agentset) - turtles, links and pathes. For turtles and relationships, you can specify a user-defined breed. And for add you already have to write brackets ( map add )Īgents come in three forms - turtles (turtle - how can they be without them), communications (link) and spots (patch - they are places in space). It works the same way map inc which returns a list of. Then you can write add add inc 1 inc 2 inc 3and get a well-deserved nine. True, functions of higher orders may be mistaken - then he needs a hint in the form of parentheses. The compiler knows “arity” (“valency”) about each procedure or function and does not require using the grouping again.
Names refer to built-in or programmer-defined entities - functions, variablesĬommands (procedures) are declared to имя įunctions in NetLogo are called “reporters” and are declared slightly differently: are used to create lists and group commands in a block in most constructions, () are ordinary brackets for subexpressions. Logo syntax is minimalistic - a space-separated sequence of names and constants with a rare grouping using or (). I want to talk about the NetLogo language, which has proven itself in education, but is also suitable for adult tasks. There are many systems designed for this, for example, the Russian proprietary AnyLogic. For systems consisting of a large number of independent objects, such as crowd behavior, the development of multicellular organisms, or military operations, agent modeling is most appropriate. Many complex systems can only be investigated by modeling.
