NetLogo Help: in-cone

### in-cone3.0

#### agentset in-cone distance angle

This reporter lets you give a turtle a "cone of vision" in front of itself. The cone is defined by the two inputs, the vision distance (radius) and the viewing angle. The viewing angle may range from 0 to 360 and is centered around the turtle's current heading. (If the angle is 360, then in-cone is equivalent to in-radius.)

in-cone reports an agentset that includes only those agents from the original agentset that fall in the cone. (This can include the agent itself.)

The distance to a patch is measured from the center of the patch.

    ask turtles
      [ ask patches in-cone 3 60
          [ set pcolor red ] ]
    ;; each turtle makes a red "splotch" of patches in a 60 degree
    ;; cone of radius 3 ahead of itself
