How many patches does NetLogo have?
The total number of patches is determined by the settings min-pxcor , max-pxcor , min-pycor and max-pycor . When NetLogo starts up, min-pxcor , max-pxcor , min-pycor and max-pycor are -16, 16, -16, and 16 respectively.
What is a reserved word in NetLogo?
patches-own, are reserved words in the Netlogo language. They can be any sequence of characters that follow Netlogo’s naming rules.
How do you make a turtle move in NetLogo?
You might try typing turtles> pen-down into the Command Center and then pressing the go button. Also, inside the move-turtles procedure you can try changing right random 360 to right random 45 . Play around. It’s easy and the results are immediate and visible – one of NetLogo’s many strengths.
What is NetLogo breeding?
This is a built-in turtle and link variable. It holds the agentset of all turtles or links of the same breed as this turtle or link. (For turtles or links that do not have any particular breed, this is the turtles agentset of all turtles or the links agentset of all links respectively.)
What is FD in NetLogo?
forward number The turtle moves forward by number steps, one step at a time. (If number is negative, the turtle moves backward.) fd 10 is equivalent to repeat 10 [ jump 1 ] . fd 10.5 is equivalent to repeat 10 [ jump 1 ] jump 0.5 .
What are globals in NetLogo?
globals [var1 …] It defines new global variables. Global variables are “global” because they are accessible by all agents and can be used anywhere in a model. Most often, globals is used to define variables or constants that need to be used in many parts of the program.
What are reserved words in basic?
1. Often found in programming languages and macros, reserved words are terms or phrases appropriated for special use that may not be utilized in the creation of variable names. For example, “print” is a reserved word because it is a function in many languages to show text on the screen.
What language does NetLogo use?
Scala
What programming language was NetLogo written in? NetLogo is written mostly in Scala, with some parts in Java. (Scala code compiles to Java byte code and is fully interoperable with Java and other JVM languages.)
How do you set the shape in NetLogo?
To begin making shapes, choose Turtle Shapes Editor or Link Shapes Editor in the Tools menu. A new window will open listing all the shapes currently in the model, beginning with default, the default shape. The Shapes Editor allows you to edit shapes, create new shapes, and borrow from another model.
What is sprout in NetLogo?
sprout number [ commands ] sprout- number [ commands ] Creates number new turtles on the current patch. The new turtles have random integer headings and the color is randomly selected from the 14 primary colors.
What does NetLogo turtle own?
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.
What’s the difference between integer and floating point in NetLogo?
An “integer” in NetLogo is simply a number that happens to have no fractional part. No distinction is made between 3 and 3.0; they are the same number. (This is the same as how most people use numbers in everyday contexts, but different from some programming languages. Some languages treat integers and floating point numbers as distinct types.)
How is the total number of patches in NetLogo determined?
Just like in the standard mathematical coordinate plane, pxcor increases as you move to the right and pycor increases as you move up. The total number of patches is determined by the settings min-pxcor, max-pxcor, min-pycor and max-pycor. When NetLogo starts up, min-pxcor , max-pxcor, min-pycor and max-pycor are -16, 16, -16, and 16 respectively.
How are links represented in NetLogo and how are they represented?
Links do not have coordinates. Every link has two ends, and each end is a turtle. If either turtle dies, the link dies too. A link is represented visually as a line connecting the two turtles. In NetLogo, commands and reporters tell agents what to do.
How does the world of turtles work in NetLogo?
Turtles are agents that move around in the world. The world is two dimensional and is divided up into a grid of patches. Each patch is a square piece of “ground” over which turtles can move. Links are agents that connect two turtles. The observer doesn’t have a location – you can imagine it as looking out over the world of turtles and patches.
