Programmier Strukturen (C++/Universell)

Ich verfasse diesen Post auf Englisch, weil mir das leichter fällt (ja, meine Muttersprache ist Deutsch). Falls Ihr lieber auf Deutsch antwortet, tut dies. I have no idea what the right word for this is. Is it structure? Paradigm? Strategy?

I have the following struct:

namespace o
{
    struct Mouse
    {
        // Button Pressed This Frame
        bool bptf;




        // Button Released This Frame
        bool brtf;




        // Button Pressed
        bool bp = false;

        // Mouse Properties
        sf::Mouse::Button button;
        sf::Vector2i position;
    };




} // Namespace o

All the properties are being updated every frame. The variable name

buttonPressedThisFrame

is extremely long, so I have shortened it to

bptf

since it is commented at the declaration anyways. Is this the correct thing to do?

I also have a function, which is called every frame, called

void handleInput(o::Mouse m)

which surprisingly enough handles all the input. The project I am currently working on has to do with nodes and mouse controls are there for the selection and moving of said nodes. So in that function I have a few if-statements. Is it better to have completely dry code and only have every if-statement once, or is it better to logically separate them?

Examle:

void handleInput(o::Mouse m)
{
    if (m.bp)
    {
        // Selection of Nodes




        // Moving of Nodes
    }




    else if (m.brtf)
    {
        // Selection of Nodes




        // Moving of Nodes
    }
}

vs

void handleInput(o::Mouse m)
{
    // Selection of Nodes
    if (m.bp)
    {




    }




    else if (m.brtf)
    {




    }




    // Moving of Nodes
    if (m.bp)
    {




    }




    else if (m.brtf)
    {




    }
}

What is to be said about my project, is that those if-statements become quite nested (up to 6 tabstops with else-statements to each of them) and also cover keyboard input combined with mouse input (e.g. Ctrl + LMB).

Which of these strategies is the correct/best one to use?
