On the topic of the thread; I'm working on making a "File Mover" tool for Uplink, because whenever I played that game I always felt a need to rearrange the contents of my databanks.
Should make for a decent exercise in getting used to how that sort of stuff works.
After seeing the Terraria example, I think no-one else can ever make that funny again.
(But I'll never find the pastebin code again... Basically every item in Terraria was checked over with an if/elseif structure - hundreds of lines! The indentation wrapped onto newlines!)

Since amc was struggling with Lua Patterns I created this small (but hopefully useful) utility:
[lua]
local help = [[Lua Pattern Help:
. (a dot) matches any character
%a : from a to z upper and lower case
%c : special characters \t \n etc.
%d : digits( from 0 to 9 )
%l : any letter that is lower case
%p : punctuation characters . , etc.
%s : space characters <space> tab etc.
%u : any letter that is upper case
%w : alphanumeric characters ( all letters and numbers )
%x : hexadecimal digits ( 0-9, a-f, A-F )
%z : null character \0
%x : represents itself ( x is any non-alphanumeric character )
[s] : Union of characters
[^s] : Opposite of the Union s
Upper case will match the opposite, %A matches non letters
Characters separated with - eg. 0-5, a-e will match everything inbetween
+ after a class matches 1 or more and the longest sequence
- after a class matches 0 or more and the shortest sequence
* after a class matches 0 or more and the longest sequence
? after a class matches 1 or 0 characters
%n ( n is a digit between 1 and 9 ) will match the nth capture
%bXY matches strings that start with X and end with Y
% is the escape character
Starting the pattern with ^ will match a string at the beginning
Ending the pattern with $ will match a string at the end]]
function Pattern(...)
local cmd = ""
print("Enter your pattern below:")
while (cmd ~= "stop" and cmd ~= "exit") do
io.write("-> ")
cmd = io.read()
if (cmd ~= "help") then
for _, str in pairs({...}) do
if (type(str) == "string") then
for match in string.gmatch(str, cmd) do
print("=> " .. match)
end
end
end
else
print(help)
end
end
end
--[[
Usage: Pattern("one", "or more strings", "you want to check with your pattern")
It'll switch into the interactive mode you can leave with stop or exit.

Fair enough, I guess I can't top that! There are quite a few places in Uplink that do similar things to this, it makes me wonder why they didn't use a hashmap or some other viable alternative that would have simplified the code a lot.

If I remember correctly, Uplink was Chris Delay's first project - literally written in his bedroom, which gave rise to their motto "last of the bedroom programmers". Given this situation, I can see why he wasn't using the most efficient\cleanest\best code - he probably didn't know any better at the time.

Also... I didn't know you could directly deal with binary values in C, I swear I read that there was only octal and hex. The whole lookup table and string representation wouldn't have been necessary if I had known that.
[QUOTE=Darwin226;33518692]Well we're working with complex number in math class and when you want to square it you first translate it to trigonometric form then the square is r^2(cos(2*angle) + i*sin(2*angle)).[/QUOTE]
You don't have to use trig to square it. It's like polynomial multiplication. FOIL.
i.e.
(x + iy)*(x + iy) = x*x + 2iyx - y*y
Remember that i = sqrt(-1) so i*i = -1.
In code this is:
[code]
z.r = z.r * z.r - z.i * z.i
z.i = 2.0 * z.r * z.i

You can't write binary constants in standard C. That's a compiler-specific extension.
You don't need it, either. Each digit of a hex character represents four bits (this is exactly why it's there), and it isn't hard to do bit-twiddling stuff in hex.
0x1 = 0b0001
0x2 = 0b0010
0x4 = 0b0100
0x8 = 0b1000
0xC = 0b1100
0xF = 0b1111
0x8F = 0b10001111
Use it a little and you'll get used to it, and start thinking in hex/binary.

Still doing something wrong, though. That's supposed to be a dragon curve...
[IMG]http://dl.dropbox.com/u/17216535/screengrab_20111201153043.png[/IMG]
Oh wow found that one by accident :D (13 iterations/levels of recursion, takes 5 mins to render)
Next up: first trying to get an actual dragon curve out of it, then ditching that and trying colour coding stuff, maybe even some 3D stuff, and in my wildest dreams a function that takes a random curve (could be your name in cursive) and uses that as a base figure.
[code]
function draak(X,Y,n)
hold on %Need to hold the current figure window, otherwise it'll draw each line segment in a new window
if n==0
axis square % x & y axis are same scale
plot(X,Y) %Plots the given line if recursion level is 0
else
m=n-1; %Reduce recursion level by 1
v=[X(1,2)-X(1,1) Y(1,2)-Y(1,1)]; %Move the X,Y line to origin (X contains the x coordinates of two points (row vector form))(Y analogous to X)
h=atan(v(1,2)/v(1,1)); %Determine angle with x-axis
R1=[cos(-h) -sin(-h); sin(-h) cos(-h)]; %Rotation matrix
R2=R1'; %Inverse rotation matrix
p=R1*[v(1,1) v(1,2)]'; %Rotate line so it's parallel with x-axis
p=p'; %Terug transponeren %Make p a row vector again
k1=[0 -p(1,1)/2]'; %k1 k2 and k3 determine the shape that replaces this line, you can modify these to change the fundamental replacement shape,
k2=[p(1,1)/2 -p(1,1)/2]'; %though try changing the stuff below first, it's easier
k3=[p(1,1)/2 0]';
l1=(R2*k1+[X(1,1) Y(1,1)]')'; %Use inverse rotation and translate them to where the X,Y line is
l2=(R2*k2+[X(1,1) Y(1,1)]')';
l3=(R2*k3+[X(1,1) Y(1,1)]')';
%Dragon curve preset:
draak([X(1,1) l1(1,1)],[Y(1,1) l1(1,2)],m) %calls the function on every line of the figure that replaces the original line, but with recursion m=n-1,
draak([l2(1,1) l1(1,1)],[l2(1,2) l1(1,2)],m) %changing these four thingies will also drastically change the curve
draak([l2(1,1) l3(1,1)],[l2(1,2) l3(1,2)],m)
draak([X(1,2) l3(1,1)],[Y(1,2) l3(1,2)],m)
end
hold off %Done drawing stuff
end
% Other preset:
% draak([X(1,1) l2(1,1)],[Y(1,1) l2(1,2)],m)
% draak([l2(1,1) X(1,2)],[l2(1,2) Y(1,2)],m)
% draak([l2(1,1) l3(1,1)],[l2(1,2) l3(1,2)],m)
%draak([X(1,2) l3(1,1)],[Y(1,2) l3(1,2)],m)
