The current value of the tick counter is shown above the view. NetLogo includes a built-in tick counter so you can keep track of how many ticks have passed. Set is used for individual variables like color/pcolor (turtle/patch), xcor/pxcor (turtle/patch), heading, etc. In most NetLogo models, time passes in discrete steps called ticks.

Netlogo code examples manual#
Basic usage examples of the different functions are shown in the examples section of the manual pages and are included in the examples/codesamples folder of the package. Therefore, by experimenting with different interaction rules and parameters, we can gain an intuitive understanding of the underlying dynamics of varied complex phenomena. For example, you could: Connect every node to every other node. For an overview of RNetLogo, its main functions are listed in Table 1. One of the beauties of ABM is that we can often observe emergent properties arising from the coded interactions between agents in the simulated world. The Code Example models mentioned throughout can be found in the Code Examples section of the Models Library. By doing so, you will learn about the wonders of agent-based modeling as a paradigm, as well as the basics of NetLogo - one of the most famous and powerful simulation environments in this realm. In this 2-hour long project-based course, you will create an agent-based model (ABM) that simulates the spread of a hypothetical virus through close contact between agents in a virtual world.
