For any bits of scripting that don't belong anywhere else. Feel free to share them here.
Newbie scripts are also accepted.

To get things started:

Having been learning how to work with math.cos and math.sin, I have achieved some wonderful results:
lua code:
len = 0
ang = 0
w,h = get_window_size()
angtbl = {}

while len <= w do
table.insert(angtbl,{x=(w/2)+(len*math.cos(ang)), y=(h/2)+(len*math.sin(ang))})
len = len + 0.1
ang = ang+0.01
end

add_hook("draw2d","y_test",function()
set_color(0,0,0,1)
draw_quad(0,0,w,h)
for i = 1,#angtbl do
set_color(math.random(),math.random(),math.random(),1)
draw_quad(angtbl[i].x-2, angtbl[i].y-2,4,4)
end
end)

Why don't you try it? :)

I was bored, so I decided to code 2 circle algorithms:
lua code:
function draw_circle_b(xc,yc,r)
local x = 0
local y = r
local p = 3 - 2 * r
if not r then return end
while y >= x do
draw_quad(xc-x, yc-y, 1, 1)
draw_quad(xc-y, yc-x, 1, 1)
draw_quad(xc+y, yc-x, 1, 1)
draw_quad(xc+x, yc-y, 1, 1)
draw_quad(xc-x, yc+y, 1, 1)
draw_quad(xc-y, yc+x, 1, 1)
draw_quad(xc+y, yc+x, 1, 1)
draw_quad(xc+x, yc+y, 1, 1)
if p < 0 then
x=x+1
p=p+(4*x+6)
else
x=x+1
y=y-1
p=p+(4*(x-y)+10)
end
end
end

function draw_circle_n(xc,yc,r)
draw_disk(xc,yc,r-1,r,r*2.5,1,0,360,0)
end

add_hook("draw2d","",function() set_color(0,0,0,1) draw_circle_b(500,300,50) draw_circle_n(700,500,10) draw_circle_n(700,500,100) end)


First one is a lua translation of Bresenham's circle algorithm, second one is a simplified version of draw_disk adapted for circles.
The hook provided is an example.

Parameters are x position, y position and radius of the circle on both functions.

A hacked startup.lua requested by john (aka box), it removes several restrictions while keeping backwards compatibility.
It removes all OS and cpath restrictions, and allows you to use the original file functions.
ex: _old_io_open("etc","w")
You can check for the hacked startup by checking the boolean _hackedstartup.
_startup.lua is the default startup.

Please don't mess around with this if you don't know what you're doing.

Great work, Yoyo. Your talent does not go un-noticed.

Working on a maze generator that john asked for, using prim's algorithm.
This is as far as I've gotten, but the maze still doesn't generate quite properly.
If anyone wants to help, feel free to.

What do you mean with "the maze still doesn't generate quite properly"? Looks like a maze to me.
Signature temporarily out of order.
