Overview

A simplistic engine may contain only a small number of top-level areas, each a zone in itself. A complex engine may have a small number of areas, but each does extensive managing of its sub-locations.

Instance Method Details

#adjacent_positions(pos, options = {}) ⇒ Array<String>

Returns an array of position strings for positions adjacent to the one given. In some Zones this won't be meaningful. But for most "plain" zones, this gives possibilities of where is moveable for simple AIs.

Returns:

  • (Array<String>) —

    Array of position strings

Since:

  • 0.0.1

def adjacent_positions(pos, options = {})
  []
end

#intentions_for_next_step ⇒ Array<Demiurge::Intention>

By default, a zone just passes control to all its non-agent items, gathering up their intentions into a list. It doesn't ask agents since agents located directly in zones are usually only for instantiation.

Returns:

  • 0.0.1
