The Beasties

Dedicated to the lovely Clarien van Harten

A beastie is an array of values: age, sex, energy, horizontal en vertical position (+ possibly other experimental properties). 
All beasties are in a List. Add with list.add(beastie), remove with list.removeAt(index). Edit with list.put(index, beastie).

Food is in a 2D-aray. 

==========================================================================
Make two beasties, a boy and a girl. They have an amount of energy and search for food, until their energy surpasses a certain amount. Then they look for a playmate. At a certain age they come of age. If a grownup man plays with a grownup woman, a new beastie comes to life. Both parent give the same amount of energy. If one of the parents hasn't enough energy, the other compensates, if possible. In that way, death of a child is prevented as much as possible.

===========================================================================
The cycle:
1. is there food where you stand?? If yes, take e byte! Energy increases.
2. Age is increased by 1.
3. Determine ypur direction
	Are you hungry? Find food.
	Not hungry? Find someone to play with
4. take the step. Energy decreases by 1.
5. as 1.
6. Is there another beastie where you stand now? Meeting.
7. Is there a meeting between a grownup man and a grownup woman? 
	If yes, birth.
============================================================================
Birth
1. New beastie in the list
	age=0
	sex=random
	position:shoot away
	energy: if possible standard initial energy.
2. energy of parents decreases.
3. When shooting away: parents jump aside, child is shot away.
============================================================================
Death
If energy == 0 and at the position where you are, there is no food.
Remove from list.
============================================================================
