Turtle stamp coloring should better match NetLogo desktop when transparency is used for the color.An exception could be generated when comparing links to turtles.Also, a bug was fixed where a stack overflow could occur with large strings. The Encode extension will generate UTF-8 strings to match the desktop version's output.
LPUT NETLOGO MOD


Many more primitives and agent built-in variables have proper runtime error checks and will now generate meaningful error messages when an unexpected condition is encountered.This should provide a small performance improvement for models that heavily use them ( lput and fput are examples). Primitives that take any kind of value (string, number, boolean, list, agent, agentset, etc) no longer check their argument types at runtime.The Table extension now contains to-json and from-json primitives for converting to and from JSON strings.The Functional Programming extension is now supported on NetLogo Web.July 6th 2022 - v2.10.0 The major feature in this release is the ability to create and edit plot widgets in NetLogo Web! Check out the Authoring mode documentation for more information on creating and editing widgets.
LPUT NETLOGO CODE
It also includes some changes to NetTango Web, including syntax highlighting in block code tips. The random-normal reporter is no longer broken as it was in v2.10.0.The random-exponential reporter is now properly checked for runtime errors.The major feature in this release is the ability to jump to the exact primitive in the code tab that causes a runtime error. Saving a model to an nlogo file with a plot with blank axes names correctly sets the values to NIL so the file can be loaded without errors.Using a variable argument primitive like word concisely with reduce would give incorrect results.When you display an anonymous procedure as a string, it will include the names of let variables.The range primitive will work when using the three-argument version.
LPUT NETLOGO GENERATOR
LPUT NETLOGO PATCH
And the one-of is to select one turtle from the set of all turtles on that patch - NetLogo can't tell that it will always have one or none so you would get an error essentially saying 'I don't know which turtle to find the colour of'. Finding north is done with patch-at 0 1 but you also have to say north of what - hence of this-turtle.

It follows fairly closely what you were trying to do - start with an empty list and then run through a list of all the turtles in who order (the sort-on turtles creates that list) and calculates the colour of the turtle on the north patch. The foreach version is probably easier to understand. of one-of turtles-on of this-turtle outlist ] Just change the print north-color-map to print north-color to try out the foreach version.
