Feature requests / Full UML Class Diagram for SFML?

« on: March 30, 2020, 10:53:35 pm »

Hello,
While i am browsing the SFML documentation, i can stumble on little diagrams showing which class inhetit who (like here : https://www.sfml-dev.org/documentation/2.5.1/classsf_1_1CircleShape.php).
I also found myself rewriting all this information on paper and trying to have a full view on all the available functions available.

I wondered if there was a full diagramm class showing all the inheritance between all classes? To have a place where you can click on any class at one glance.

General / How to be more efficient and faster in coding?

« on: March 16, 2020, 11:37:14 am »

Hello,
Since the coronavirus outbreak, and even before, i tried to spend some time to try to make my first game, and  it made me realize that i had to relearn all of SFML through tutorials since i am pretty new to SFML and the only free courses i took on SFML were not enough to cover everything.

But i find myself very slooww, what i thought finishing in one night, i found myself doing it in many days.

I tried to ask myself the question, how to get things done and be efficient in coding and code learning? i tried to see my patterns and see what "distracted" me.

I am curious about your experiences and your solutions. How do you learn a new langage fast? How do you code and focus and get things done fast with no distractions? What's your best and more efficient methods.

Thanks,
P~

SFML wiki / Confusion while Reading the documentation on : Events

« on: March 09, 2020, 07:59:52 pm »

Hello,

(I am still new to c++, but i made quite lot of progress, i am not a computer science student although.)

I have a question that could appear "non intelligent" but it kinda confused me. Here it is:
While using the "window" module, its functions were easy to use and pretty straighforward (https://www.sfml-dev.org/documentation/2.5.1/classsf_1_1Window.php)
The "Public Member Functions" section contains all the functions at one glance, for instance i can use window1.isOpen() if i created and object called window1 from the classe Window.

But then i went to the event page (https://www.sfml-dev.org/documentation/2.5.1/classsf_1_1Event.php)
because i wanted to check an example that i had read from here : https://www.sfml-dev.org/tutorials/2.5/window-events.php which is below:

         
  if (event.type == sf::Event::MouseWheelScrolled)

 {
 if (event.mouseWheelScroll.wheel == sf::Mouse::VerticalWheel)
   cout << "wheel type: vertical" << endl;
else if (event.mouseWheelScroll.wheel == sf::Mouse::HorizontalWheel)
 cout << "wheel type: horizontal" << endl;
else
 cout << "wheel type: unknown" << endl;
 cout << "wheel movement: " << event.mouseWheelScroll.delta << endl; // this line
 cout << "mouse x: " << event.mouseWheelScroll.x << endl;
   cout << "mouse y: " << event.mouseWheelScroll.y << endl;
                }

I got confused when i read this part "  event.mouseWheelScroll.delta",

What is : "mouseWheelScroll"?
It can neither be found on the classes section of the Event pages nor the public types, i can see it on the public Attributes somehow.
Checking the Event.hpp page : https://www.sfml-dev.org/documentation/2.5.1/Event_8hpp_source.php, i don't find "mouseWheelScroll", only "MouseWheelScrollEvent" and "MouseWheelEvent" which are different from "mouseWheelScroll".
As for the "delta" in "event.mouseWheelScroll.delta" no confusion, it's one of variables of the structures i found on the "Event.hpp" page.

Sorry if the answer is obvious, maybe i miss something in c++ that i still need to learn. If yes, please do enlighten me.
Thank you

Graphics / Do these three features exist? [Solved]

« on: March 08, 2020, 08:42:14 am »

Hello,
I was very exciting to discover SFML and the world of programming,
Now i have few quick questions if someone expert knows the answer

1) Is it possible to draw an object (with paint) and use some kind of tool/programm to transform it into a real in game item with the exact shape you have drawn?  (meaning the item will have the collision area you have drawn)

2) Is there a function to merge items/objects into 1 item? (example : 2 circles meet each other (one circle hits the other), resulting in making one single item with a shapre of "8")

3) Is it possible to give an item, let's say a rectangle, 4 different kind of interactions with other items depending on which side of the rectangle was hit by another item? (So if a user rotated the rectangle to make it hit with the side number 2 or 3, the result would change, my question is, can SFML differenciate between the 4 sides of the rectangle?)

Thank you
And a have a good day
P-
