Create a new model of ants

Create a new model where, starting from min-pxcor = 0 and min-pycor=0, the width and height of the world can be varied (together) between 10 and 50 (slider; processing within the setup procedure). Create another slider where the number of "special patches" can be selected from the interval between 1 and 20. These "special patches" are to be randomly deployed on the playing field (and randomly coloured either red, blue, yellow or green) as part of the setup procedure, where each "special patch" must have a minimum distance of 4.5 "patch lengths" to any other "special patch". more in File!
