SDL2_pollevent() Controller dpad continuous hold? - c++

Question

I'm trying to register controller button/dpad presses and continuous hold of said buttons that way it spits the output out continuously instead of one press at a time and then exiting the poll event loop. Right now I have a small piece of dummy code that I'm trying to print in a stream if I hold a button down. Any assistance into this issue?
while( !quit_program )
{
//Handle events on queue
while( SDL_PollEvent( &e ))
{
//User requests quit
if( e.type == SDL_QUIT )
{
quit_program = true;
}
else if(e.type == SDL_CONTROLLERBUTTONDOWN)
{
count++;
cout<<"button pushed# "<<count<<endl;
}
}
}

Answer 1

Until you get a SDL_CONTROLLERBUTTONUP (for the same button of course) you can consider the button as being pressed. Then to count you could do something like this (for a single button):
bool that_button_pressed{false};
while(!quit_program) {
//Handle events on queue
while(SDL_PollEvent(&e)) {
// User requests quit
if(e.type == SDL_QUIT)
quit_program = true;
if (e.type == SDL_CONTROLLERBUTTONDOWN && e.button == a_button_of_your_choice) {
that_button_pressed = true;
}
if (e.type == SDL_CONTROLLERBUTTONUP && e.button == a_button_of_your_choice) {
that_button_pressed = false;
}
}
if (that_button_pressed) {
count++;
// Print or implement your logic
}
}
Of course this counter would also depend on your loop timings. Here that_button_pressed would represent one of the SDL_GameControllerButton's.
