so i just found in the original project two little snippets of code put inside of a multiline comment.
The first one being this
if e.altshoot then
x = x - width
e.altshoot = false
x = x + width
e.altshoot = true
which by removing the
--[[ from the start of it and the
]] you unlock a different stream of bullets for you main ship with it alternating from a left and right stream.
and the second code snippet is a neato explosion for the enemy ships (and yourself!)
local sqrtfrac = math.sqrt(e.frac)
for i=36, 360, 36 do
local lr = i * (math.pi / 180)
local r = 10 + sqrtfrac * 100
local c = math.cos(lr) * r
local s = math.sin(lr) * r
_r.sprite(x+c,y-s,2,4 + b * 20,lr - math.pi * .5)
which again by removing the code block ends you unlock the cool animation for deaths!
these are just little things i found when exploring the code trying to figure out how to make a cool thing, so i thought i'd share them since i hadn't seen them mentioned anywhere.
