BehaviourComposer: ignore everything before this.
Set the value of an attribute of all patches.
End descriptionPatch attribute
Begin NetLogo code:
substitute-text-area-for attribute-name some-attribute-of-patch substitute-text-area-for patch-attribute-value 42 ask-every-patch [set attribute-name patch-attribute-value]
End NetLogo code
The first text area can be any NetLogo patch variable (pcolor plabel plabel-color pxcor pycor) or a name that ends with '-of-patch'. The second text area can be any expression or value. An example is the micro-behaviour that gives each patch a different random color.
This uses the Behaviour Composer NetLogo command ask-every-patch [...] which is a faster but equivalent to NetLogo's ask patches [...]. It uses NetLogo's set command.
Patch attribute was first implemented by Ken Kahn on 19 November 2011.
