I have a few variables which can be inherited to child agents by a variation of + 0.1 and -0.1 or without any changes, or random again, What I have done is like this: (The code is just an example) to reproduce ask turtle 1 [ let X-Of-Mother X hatch 1 [ set X one-of (list (X-Of-Mother) (X-Of-Mother + 0.1) (X-Of-Mother - 0.1) (random-float 1)) ] ] end Currently I have to check if X of child turtle is always within range by something like this: if X > 1 [set X X - 0.2] if X < 0 [set X X + 0.2] What could be a better way to do it? What if I have to use random-normal 0.5 0.1 , how can I limit that

I would like to add forest patches in a landscape. To be more precise, the idea is to add patch clusters like "Patch Clusters" example. Contrary to this example, I want to randomly distribute some patch clusters with the same color and not several clusters that fill entirely the landscape. This is a beginning of code : to create-forests repeat 30 [ ask one-of patches [ set pcolor green ask neighbors [ set pcolor green] ] ] end With this code, the clusters look like squares and not clusters like "Patch Clusters" example. How can I add forest patch clusters in my landscape ? Thank you for your

I am trying to make a Frogger-like game in NetLogo and I need to create a timer that counts down. However, I looked in Frogger and used the same procedures that create the timer but it does not work. Please advise. How to create a count-down timer in NetLogo This is a general outline of how to implement a count-down timer. This applies both to a real-time count-down, or a simulation-time count-down. Implement a variable to contain the remaining time or elapsed time. The variable is usually a global variable, unless each agent must have its own count-down. Then the variable will be a -own'd

Is it possible to create random shapes (see below for example) of a given area in NetLogo? A first stab at Seth's suggestion #1. It creates a neat visual too! patches-own [ height ] to blobbify clear-all repeat (ceiling 2 * (ln (world-height * world-width))) [ ask patch (round (random (world-width / 2)) - world-width / 4) (round (random (world-height / 2)) - world-height / 4) [ set height world-width * world-height ] ] while [ count patches with [ height > 1 ] < (world-width * world-height / 4)] [ diffuse height 1 ask patches with [ height > 0 ] [ set pcolor height ] ] ask patches with [

I have about 5000 agents (people) in my model. I want to give them an arbitrary number of friends and have reciprocal but random pairing. So if person A chooses person B then person B also chooses person A. My code works fine, but is fairly slow. I will likely want to increase both the number of friends and the number of people in the future. Any quicker suggestions? ask people [ let new-links friends - count my-links if new-links > 0 [ let candidates other people with [ count my-links < friends ] create-links-with n-of min (list new-links count candidates) candidates [ hide-link ] ] ] Note
