how can i change text when pausing / resuming phaser game?

Question

I'm trying to toggle between 'Pause' and 'Resume' text when pausing and resuming, i tried the following in create:

gameState.playPauseText = this.add.text(660, 547, 'Pause', { fontFamily: 'Roboto Mono, monospace', fontSize: '20px',  fill: '#FFFFFF' });

then tried changing that inside a callback function:

gameState.playPauseArea.on('pointerdown', () => {
        if(!gameState.isPaused) {
            gameState.playPauseText.setText('Resume');
            game.loop.sleep();
            gameState.isPaused = true;

        }
        else {
            gameState.playPauseText.setText('Pause');
            game.loop.wake();
            gameState.isPaused = false;
           
        }
    });

then i tried same, but changed .setText to .text =. The best i got from all above is to change text to 'Resume' after 2 clicks, but never back to 'Pause'.

I also tried the following in update:

if(gameState.isPaused) {
        gameState.pauseText.setText('Resume')
        

    } else {
        gameState.pauseText.setText('Pause');
       
    }

that didn't do anything.

I also tried creating two separate texts and hiding one with setVisible(false) and tried all of the above toggling both 'Resume' and 'Pause' between setVisible(true) and setVisible(false).

also nothing.

I use .setText() somewhere in my code, to change score text and it works fine.

The problem is, that you are stopping the game loop, so nothing is going to be painted/updated any more. You could call the game.loop.sleep() with abit of delay, so that a repaint, will still be triggert.

...
setTimeout( () => game.loop.sleep(), 50);
...

Or with the Phaser delayedCall function:

...    
this.time.delayedCall(50, game.loop.sleep, null, game.loop);
...

here a short demo:

document.body.style = 'margin:0;';

var config = {
    type: Phaser.AUTO,
    width: 536,
    height: 183,
    scene: {
        create
    },
    banner: false
}; 

function create () {
   let text = this.add.text(30, 90, 'Click me to start');
   let pause = false;
   
   this.input.on('pointerdown', () => {
    if(!pause) {
            text.setText('Click me to Resume');
            setTimeout( _ => game.loop.sleep(), 50);
            pause = true;

        }
        else {
            text.setText('Click me to Pause');
            game.loop.wake();
            pause = false;
           
        }
   })
}

let game = new Phaser.Game(config);
