Anyone familiar with SFML - C++

[Gatorade]

^ If you are and you would be interested in eithor sharing some knowledge on how you came to learn it / be willing to write something for me I will pay you in game or real $ depending on your preference. No its not for HW its to finish a project that I couldn't complete last semester that my OCD is yelling at me for. (Serpinski's Triangle using SFML in C++ first for regular lines then for fractal lines)

This was the coding environment:

This was the assignment I failed that was bothering me why I didnt understand it:

used to have C++ about 2 years ago, sadly i don't remember alot of it.

Im taking a Comp Sci class, But were only learning in Java, If you want to know the basics I could show you some great sites to learn on, Most code platforms are very similar, Just sometimes they have different syntax. 

 

Whats the problem like?

It's pretty easy, hit me up in a PM if you need some starter help.

Well its honestly retarded. Its this dog shit library where you are forced to use things preset to load in different graphics and sound with your files to create different types of games and things. Problem is half the stuff doesn;t work properly or its poorly explained inside of the SFML documents and website.

 

Its to the point where it really doesn't encorperate any foundations that C++ really should other then the fact that it uses alot of inheriting

 

Edit: I put the stuff in the first post for the environment and assignment to make it more clear then my explanation

If you can figure out how to draw a serpinski's triangle in SFML using C++ ill pay you whatever you want in asylum money. Ive found code online that i tryed encorperating and running and none of it has worked. I use a linux type environment to run it. This was the assignment in the spring - I failed this one bad

Just to clearify its not against the rules  to exchange some asylum money for I guess you would call it tutoring right?

Wrote a script in Python to do it.  Obviously, this is not C++ nor the library you specified, but the logic and arithmetic will be the same.

I tryed reverse engineering one from python on the internet and it came out terrible

How so?  There really isn't a need to reverse engineer.  First, you need to understand how the program will work recursively.  All recursive functions have two main parts:

1. The Base Case: when do we want to stop

2. Else: what to do until we reach the base case

I imagine the library will require you to draw a polygon using coordinates.  Thus, a triangle will be made up of three coordinates (lower left, top, lower right), where each of those coordinates will be an X value and a Y value.  Our base case can be when we need to draw the big triangle, so it will just need the proper coordinates to do that (basic arithmetic will yield you that).

Now, we must figure out what to do until we reach the case were we need to draw the big triangle.  I find it best to look at it this way:

Imagine the next step beyond the big triangle.  That will be when there are three triangles inside the big triangle.  Let's call those A, B, C.  If we look closely, we see that each of these A's, B's, C's, will also contain three triangles.  Thus, it is a pattern.  So, theoretically, if we can tackle this first case of splitting the triangle into three triangles, then we solve the entire problem through recursion!

Now, through some geometry, you can figure out the coordinates of these three triangles.  Just pretend there is only one level of recursion to simply the problem in your head.  Then, you have to do what I consider the most important part of development/engineering: DEBUG!  Recursion requires a "leap of faith", as the concept can quickly go above one's understanding.  Trial and error is the key to solving problems such as these for beginners.  This is the best way to pick up the fundamentals of programming logic.

In 6th grade our computer science teacher taught the class Java and C++ but I forgot shortly after.

So essentially you are starting with one big ass triangle probably the size of the window and recursively dividing it by an algorithm that takes n divisions and uses it to make sub triangles with three different variables, one for each vertex of the triangle?

googie is that how you communicate with your fellow members? "wrote in python ... "  from all the softwares you choose Python => a snake ? a snake with triangles on it's skin. triangles within triangles. every triangle is a role. triangiception. googie head of IlluminatiTee (IT) departement confirmed.

btw what does HW mean?
