// Each species has a "name", a character that is

// Sensor parameters
// There are three sensor types: touch, vision, and
// sonar.  A critter species only gets a sensor if
// at least one of its parameters is specified.

// Touch
// Touch has only one parameter, the range of cells
// that can be touched (1 - 6).

touchRange		3

// Vision
// Vision has two parameters, resolution, that is, the number
// of "pixels" available on the retina (3 - 9),
// and the visual angle (60 to 360 degrees).

visualResolution	3
visualAngle		120

// Sonar
// Like vision, sonar has two parameters, resolution, that
// is, the number of "rays" that are sent out, each returning
// a distance value (3 - 9), and the angle that is observed
// (60 to 360 degrees).

sonarResolution		3
sonarAngle		120

// Effector parameters
// There are five effectors: rester, turner, mover, eater,
// and hitter.  For each the number of possible
// actions can be specfied (1 - 5 for turner,
// 1 - 3 for mover, 1 only for eater, and 0 or 1
// for hitter and rester). All critters get a turner, a
// mover, and an eater.  Critters have a hitter 
// only if "hit" appears in their species specification and
// a rester only if "rest" appears in their species
// specification.

// rest			1
turn			2
move			2
hit			1

// Reinforcement learning parameters
// Each of these is an integer representation of
// a real number.

// Learning rate: the integer * .01

//vary this: 
//	1=not high enough to learn before death
//	5=sometimes learn, sometimes don't
//	10=always learn
//	20,25=too high! -- always die (why?)	
learningRate            5

// Discount rate: the integer * .1

// Action parameter
// This affects the probability that an action
// is selected on the basis of its value for the
// current state.  The actual value is the integer
// * .001.
