Does it matter if a function is called within or outside the event block?

[kim366]

Do the following code snippets do the exact same thing?

while (window.isOpen)
{
        sf::Event event;
        while (window.pollEvent(event))
        {
                if (event.type == sf::Event::mouseButtonPressed)
                {
                        // Do something here
                }
       
        } // Poll Events

} // Game Loop
 

bool bolean;

while (window.isOpen)
{
        bolean = false;

        sf::Event event;
        while (window.pollEvent(event))
        {
                if (event.type == sf::Event::mouseButtonPressed)
                {
                        boolean = true;
                }
       
        } // Poll Events

        if (boolean)
        {
                // Do the same thing here
        }

} // Gameloop
 

I am asking this, because you mentioned some sort of delay and timing in my last question and I want to know, if I am understanding this right, so sorry if this question seems stupid.

Thanks,
Kim

This would be a pretty common thing to do. Setting a variable from an event and then processing it outside the event loop makes a lot of sense.

I don't think you could consider this a 'delay'. Processing the event loop is mostly almost instantaneous; consider the fact that the final event to be processed is at the end of the loop. The following code (outside of the event loop) is then immediately executed.
Note that the entire "cycle" of the game loop will be happening many times per second so each one could be very quick indeed.

Thanks! Makes sense

If you have 2 (or more) mouseButtonPressed events at the same time (for example left mouse click and right mouse click at the same frame), "do something" will be executed twice in the first snippet of code but only once in the second.
