----(THIS IS JUST A LITTLE BIT OF CODE FROM THE PROGRAM)----

My program renders 3 menus  at the moment: startMenu -> mainMenu -> resourceMenu.

all menus handle sf::Event::KeyPressed: (Enter/Up/Down).

in resourceMenu when i press enter a number gets updated on the screen.

THE PROBLEM is that when i press enter from the mainMenu-Screen, the resourceMenu also registers that Enter was pressed and thus the resource number gets updated as soon as the resourceMenu is rendered to the screen.



What i want to achieve is this:

mainMenu (if Enter is pressed) -> resourceMenu displayed (if Enter is pressed) -> update resourceValue.



what i have:

mainMenu (if Enter is pressed) -> resourceMenu displayed (and since you pressed Enter in mainMenu resourceValue will be updated from that keyPress)


i guess i want to separate the sf::keyboard::Enter from each menu and make it so that the menus don't respond to eachothers keypress-Events.



Thanks in advance!

You can put your if inside else if you don't want to have multiple menus active during the same frame.
if (this->mainMenuActive)
{
   mainMenuEvents();
}
else if (this->startMenuActive)
{
   this->startMenuEvents();
}
else if (this->resourceMenuActive)
{
   this->resourceMenuEvents();
}
