#eqly_spaced(possible_hits = 4, chance = 1, ignore_first = 0, ignore_last = 0) ⇒ Object

Adds into #hits.

possible_hits

number of hits that can occur. Must be int

chance

chance a hit will be included. range: 0 to 1

ignore_first

skip the first n possible hits

ignore_first

skip the last n possible hits

e.g. disperse_hits(16,1,4,4) makes this pattern [-|-|-|-|+|+|+|+|+|+|+|+|-|-|-|-|]
