Let's experiment with the effect of these controls. • Press "setup" and then "go" to start the model running. • As the model runs, move the slider in the control strip back and forth. What happens? This slider is helpful if a model is running too fast for you to see what's going on in detail. • Move the speed slider all the way to the right again. • Now try pressing and unpressing the red arrowhead in the control strip. • Also try pressing and unpressing the on/off switch in the control strip. What happens? NetLogo 3.0.2 User Manual The shapes button and the freeze button are useful if you're impatient and want a model to run faster. When shapes are turned off, turtles are drawn as solid squares; it takes less work for NetLogo to draw squares than special shapes, so the model runs faster. The freeze button "freezes" the view. The model continues to run in the background, and plots and monitors still update; but if you want to see what's happening, you need to unfreeze the view by turning the switch back on. Most models run much faster when the view is frozen. The size of the view is determined by three separate settings: Screen Edge X, Screen Edge Y, and Patch Size. Let's take a look at what happens when we change the size of the view in the "Wolf Sheep Predation" model. • Experiment with the three sets of black arrows on the left of the control strip. What happens the first time you press one of them? What happens after that? Try all three sets of arrows. The arrows give you a convenient way of changing the number of patches in the world. NetLogo can't change the number of patches without starting the model over from the beginning, so that's why it warns you the first time you press an arrow. There are more world and view settings than there's room for in the control strip. The "Edit..." button lets you get to the rest of the settings. 30 Tutorial #1: Models
• Press the "Edit..." button in the control strip. A dialog box will open containing all the settings for the view: What are the current settings for Screen Edge X, Screen Edge Y, and Patch Size? • Press "cancel" to make this window go away without changing the settings. • Place your mouse pointer next to, but still outside of, the view. You will notice that the pointer turns into a crosshair. • Hold down the mouse button and drag the crosshair over the view. The view is now selected, which you know because it is now surrounded by a gray border. • Drag one of the square black "handles". The handles are found on the edges and at the corners of the view. • Unselect the view by clicking anywhere in the white background of the Interface tab. • Press the "Edit..." button again and look at the settings. What numbers changed? What numbers didn't change? NetLogo 3.0.2 User Manual The NetLogo world is a two dimensional grid of "patches". Patches are the individual squares in the grid.
