[Solved] Setting a boolean once in a infinite loop?

Newbie & Debugging Questions
#1 
            Alright so let's say I press a Key to make the game be able to pause, when I press that key I want the game to be paused and have to be pressed again to un-pause. Problem is, press said key makes it pause and pause almost instantly and keep doing that. Any help? I would suppose it would have to do with having my own input listener that checks for individual presses instead of having the button held.

if(Gdx.input.isKeyPressed(Keys.ESCAPE)){
			if(gameScreen.isPaused() == true){
				gameScreen.setPaused(false);
			}
			else{
				gameScreen.setPaused(true);
			}
		}

Either use isJustPressed or a listener.

Thanks again burnt pizza. Well I had a stage with the buttons and implemented InputProcessor on my HUD class and then created an Input Multiplexer to add both the HUD class and the stage. Works perfectly :D, and to think I looked over that a while ago thinking I would have no use for it since it seemed complicated! ;D 8)

I know it’s solved already, but another option is to use Gdx.input.isKeyJustPressed(Keys.ESCAPE). It’s meant for polling, but it’s not preferred over an event listener.

#5

And for the sake of completion, if the above solutions didn’t exist, we could do this ourselves by setting a flag when we press the key, and only run the event if this flag isn’t set. The flag is unset when the key is unpressed.

A flag? So just another boolean? Wouldn’t that make the class pretty clunky if you have multiple booleans devoted to running methods once?

#7

The way you have it there’s already multiple if statements devoted to it…

I use a similar system for things like key input , I dont want the person to spam in 50 letters just by tapping , a flag boolean is set when the key is pressed , if its true then do not call the handler function , call the function on the keypress then thats it. Then detect when the key is no longer pressed and reset this flag to false . Simples.
