Unit Movement

This site explains how units decide to move.

Decision

Chooses randomly any of these possibilities, of none remains the unit does not move (e.g. stands still on tile where it was spawned)

Priority =>	Low	Middle		High
	Move to an reachable ..			Attack an ..
Type	town-center[1]	enemy[2]	enemy-building	enemy	enemy-building
		.. in sight-range		.. in sight-range, in line-of-sight, and in attack-range
Melee	x	x	x
Archery	x	x	x	x	x
Siege Melee	x		x
Siege Archery	x		x		x

Every target's possibility is overridden by it's highest priority. (e.g. if an archery could move to an enemy AND attack it, it would never move to it)

Melee units attack when their on the same tile as the target.
