[ARC]-Roadkill's programming tutorial part I-

*stickied by scio

All right here we go. If you would like to learn to program, I will help. Please note that LUA is very foreign to me, and I probably shouldn't be teaching about it. If someone wants to add LUA, feel free to do so.

First off, programming is easy. Especially when you know the basic commands in a program. A program executes these commands flawlessly and very fast.

First off, the variable.

Variables are defined like this:

Code:

//THIS IS A COMMENT.  IT IS IGNORED BY THE COMPILER, SO YOU CAN TYPE
//WHATEVER YOU WANT BEHIND IT.

/*
YOU CAN ALSO COMMENT LIKE THIS
*/

//THE FOLLOWING LINE DEFINES myNumber AS THE NUMBER 1
var myNumber = 1;

//THE FOLLOWING LINE DEFINES myString AS THE STRING "I'm a pirate"
var myString = "I'm a pirate";

What's a string, you might ask? It's a collection of characters strung together.

Code:

//IF YOU REMEMBER YOUR BASIC ALGEBRA, YOU CAN DO THIS TO
var number1 = 1;
var number2 = 2;
var number3 = number1 + number2;

//THE + OPERATOR CAN ALSO APPEND THINGS TO STRINGS
var string = "number1 = " + number1;

If we were to output number3, it would be the number 3.
If we were to output string, it would be "number1 = 1".
We will cover this later.

Code:

//HERE'S SOME MORE ALGEBRA
var number1 = 1;
var number2 = 5;
var number3 = 2;

var number4 = number1*number2*number3;

var number5 = number4/2;

number4 would then be... You guessed it! 10!
number5 would then be... 5!

Now for the quiz!

I need you to write me a program that creates a human readable string containing the following variables. x, y, z, rotation, dx, dy and dz.

Please do not post the answer in the comments section, pm it to me instead. Thanks!

Also, could we change the text color inside the code blocks to something like black?

I might add Lua if I ever find some time..

I quit.

want some lua?

Code:

--lua prime gen i made a while ago (i'll add the one that records to a file if i find it....
numbers = {}
n = 1
_G["return"] = (function ()
return numbers
end)



work = (function (number,tab)
a = false
i = 2
if #numbers > 2 then
repeat
got = number/tab[i]
if got == math.floor(got) then
a = true
else
i = i+1
end
until a == true or i >= #tab
end
if a == false then
table.insert(tab,number)
print("number"..number.."Is It")
end end)

coroutine.resume(coroutine.create(function ()
b = false
repeat
work(n,numbers)
n = n+1
until b == true end))

lua is not that hard.

variables 101.

you dont need to define the type of any variable. if you say lol = 42 it automatically says that lol is a int with value 42.

variables and even functions, tables and threads can many times remain anonymous, which means they need not their name to be determined

lol = 42 --number
var = "42" --string
bool = true --bool
fun = (function ...end) --function
coroutine.resume(coroutine.create(function() end)) -- notice that function ha not been defined



i know lua (though i do not have much experience with metatables) and i've started to learn C++ (but school has left me with no time to learn though)
see lua.org for details and stuff...

@roadkill

i think you mean something like this:
var = "x, y, z, rotation, dx, dy and dz"
the output would be: x, y, z, rotation, dx, dy and dz
you might also mean to something like this:
val = "x"
val2 ="y"
var = val..","..val2

...I'm pretty sure that was part of the quiz.

And I thought Sven was a dictator!

Oh, em, I mean I pass.

Please?

Not eneryone needs to program. It's actually a bad idea to have everyone here programming, because lots of people really aren't clear on all of our current ideas. Too many cooks will undoubtedly spoil the broth.

So, thank you very, very much for putting this up, but I'm the one calling the managerial shots here, ok?

First they should learn Console input and output with mathematics, then teach them OpenGL.

Lovely, but until I can do more than smack at my calculator, I stop at algebra.

Though thank you for putting this up, as it gives me an idea of the math that will be required in order to define our biomes and population dynamics.

Mysterious Calligrapher, you are doing a splendid job at giving us information and doing the science! You are not required to learn how to program, as i see it, you are way to much needed in the science section and making concept arts.

However, it would maybe proove beneficial to have you learn a little bit, so that your concepts don't go overhand and are actually realistic to accomplish

I agree, I probably ought to have a look at the basics of math that the system can handle before I dump a lot of theorems on you.

I'm almost finished with finals, though, and I'm still hard at work on the biomes - I'm mostly interested in knowing if the math I've got for biome determination for the automatic placement can be handled by the programming... and unfortunately scio has class during the day, so I can't be pestering him for the answers all the time.

Kudos to you lot who actually make the machines accept all this math.
