WHAT IS IT?
This is the following model of "Good morning turtles". Now each turtle can have its own values for close,far,and color. see "Good morning turles"
HOW TO USE IT
Each turle has its values defined by two sliders, "close", "far", and one chooser for its color.All those values can be changed when running the simulation.
The initial position of the turle is set by a chooser "Start-from".It may be random....
There is also a "go once" button which when hit, changes the mind of all turtles...
Of course you can simulate the previous model by just setting the "same" switch On
The "background" slider allows you to change the background color when running. The "change background" allow the same thing but when go button is off.
THINGS TO TRY
...Set "same" swith On.
...Set the sliders : number of turtles to 5, facing slider to 1, close-all to 0.5, far-all to 30 then run the model.... watch what happens....You can change while running the model the sliders close-all and far-all to see what happens...
... set the sliders : number to 7, increment to 1 and change when running close value to 0.5 or less and then back again to 1 or more ....some settings seems very unstable
... set the sliders : number to 7, increment to 3 and change when running close and far sliders ....some settings seems very stable
Play with different settings , modifying close and far values to get different drawings....
... set close value to 0.5 or less, wait a few seconds and move it back over 0.5, if it doesn't seems chaotic, move back to 0.5 or less ...until the path seems unpredictable then just watch ...you can also change far value.
In fact I don't know why this is happening .....
...Set "same" swith off and play with the different settings to get nice drawings
