![]() ![]() For example, if you create a tree shape, you should either name it with a different name such as "tree 2" or you should first delete the default tree shape from your model. The name of your new shapes have to be unique.You can uncheck the Rotatable option to prevent your shape from being rotated when a turtle's heading changes.You can uncheck the Snap the grid option to draw shapes with higher precision.That is, if you draw an object with this color, you can override this color with the set and color primitives. You can pick a color that represents a changing color.If none of the shapes in the library fits our model, we can create new shapes from scratch by clicking the New button and drawing our own shape.Ī few things to keep in mind while using the New Shape Editor: All we need to do is to click the Import From Library button, which will bring up a long list of shapes to choose from.Ĭreating new shapes and editing existing ones NetLogo has way more turtle shapes than the default ones for us to choose from. Fifth row: star, target, tree, triangle, triangle 2, truck, turtle.Fourth row: line half, pentagon, person, plant, sheep, square, square 2.Third row: face sad, fish, flag, flower, house, leaf, line.Second row: circle, circle 2, cow, cylinder, dot, face happy, face neutral.First row: default, airplane, arrow, box, bug, butterfly, car.Some of these shapes, called default shapes are embedded within each new NetLogo model. NetLogo already has a lot of pre-designed shapes for us to use. This way, when we resize a turtle, its image does not loose quality (i.e., does not become pixelated). They are built up from basic geometric shapes squares, circles, and lines, rather than a grid of pixels. In NetLogo, turtle shapes are vector shapes. Note: You can visit the NetLogo User Manual at for more information on Shapes and Colors* ![]() If you would like to learn more about how to use the shapes editors and the color swatches, read along. NetLogo includes a Turtle Shapes Editor, a Link Shapes editor, and a Color Swatches panel that allow us to create agent-based models that do not only represent real-world phenomena conceptually, but also create powerful visualizations of our agents. For others, creating pleasing and creative visualizations may simply augment our enjoyment of the modeling process and help us communicate our ideas better with others. For some phenomena, modeling the way agents look is almost as important as modeling how they behave. ![]()
