Netlogo colors6/20/2023 ![]() Use deg() from CircStats to convert the result in degrees.Ĭlear-all (ca): not implemented. To execute a function similarly as ask-concurrent, the function needs to be provided with one agent at the time.Īt-points: turtlesAt() from NetLogoR or patchAt() from NetLogoR.Ītan: atan2(), returns value in radians. When multiple agents are provided in a NetLogoR function, they all execute the function at the same time. The agents running a NetLogoR function is one of the function arguments that need to be provided.Īsk-concurrent: not implemented. Use deg() from CircStats to convert the result in degrees.Īsk: not implemented. Use deg() from CircStats to convert the result in degrees.Īrithmetic operators: +, *, -, /, ^,, = or = (depends if it is for setting or testing), !=, =.Īsin: asin(), returns value in radians. The NetLogo primitives not implemented should not prevent the users from building individual-based models involving patches and turtles.įor the inverse dictionary ( i.e., to find the NetLogo equivalents of the NetLogoR functions) please look at the NetLogoR documentation as the links to NetLogo Dictionary entries for the equivalent primitives are provided in the “See Also” section of each NetLogoR function.Īcos: acos(), returns value in radians. When no NetLogoR function was built to translate a NetLogo primitive and that, to our knowledge, no R function (or from other packages) could easily recreate the primitive, we indicated “not implemented”. ![]() To find how to use these functions, please refers to their documentation by using help("nameFunction"). ![]() Are suggested as replacements, functions from the NetLogoR package, as well as functions from the R software and of other packages (indicated below). It lists all the entries in the NetLogo Dictionary ( i.e., NetLogo primitives) and informs the best replacements to use in R. However, if there is a green plant on the same patch, our sheep eats the green plant.This document is based on the NetLogo Dictionary. When there is a yellow plant on the same patch, our sheep just ignores it. We use the ask turtles with to just ask the sheep to move, while the plants remain stationary. We use the color primitive to make some of the plants green and some yellow. In the model example below, we have a white sheep and some plants. You can also use non-integer numbers to achieve an even more precise color such as red + 0.25or blue - 1.85. For example, green + 2is will result in a lighter green color, while green - 2 will result in a darker green. This allows us to manipulate the lightness of colors with simple math. As NetLogo uses a simple numbering scheme for colors, you can actually treat color names like numerical values.You should write the name of a color directly, without any quotations around the color name ( "").These names are: red, green, blue, brown, black, pink, white, violet, magenta, cyan, and gray. As you noticed in the examples above, you can use the names of the common colors directly in your code.You can access this color numbering scheme by clicking the Tools menu and choosing the Color Swatches option. NetLogo uses a custom numbering scheme to represent colors.ask turtles [Ĭolor is also a reporter we can use it to access the color of a turtle as follows: ask turtles with [ We can use the set primitive and the color primitive together to change a turtle's color as follows: set color red. Every time we create new turtles, each one is assigned a random color. Color is a built-in turtle characteristic that represents the color of each turtle in a NetLogo model.
