如何在Phaser中获得ActivePointer按下的精灵持续时间

Question

I'm creating pinball game using Phaser Framework .

When the ball holder is pressed (please check attached screenshot so you have an idea what I mean ball holder), depending on the press speed, it should move the ball around the spiral channel. So now trying to detect the down pressed duration of the holder.

Here is my code:

var ballButton;
ballButton = game.add.sprite(196, 100, 'ballHolder');
ballButton.inputEnabled = true;
ballButton.events.onInputDown.add(inputDownAction, this);

function inputDownAction(ballButton, pointer) {

    /* returns 0 */
    console.log( pointer.duration);
}

So pointer.duration is not working and returns 0 .

But game.input.activePointer.duration inside update() function is working and returns duration.

if (game.input.activePointer.duration > 200 && game.input.activePointer.duration < 500){
    console.log('first range '+game.input.activePointer.duration);
}else if(game.input.activePointer.duration > 500 && game.input.activePointer.duration < 700){
    console.log('second range '+game.input.activePointer.duration);
}else if(game.input.activePointer.duration > 700){
    console.log('third range '+game.input.activePointer.duration);
}

How can I make it work for specific item/sprite? Any ideas please?

Answer 1

in phaser 3 something like

function update(){
 var duration = 0
 if( this.input.activePointer.isDown ){
  duration++;
 }
}

Answer 2

You can get the time from the scene and calculate it with the downTime from the activePointer. So, you can try this approach:

function update(time, delta){
    console.log(time - window.game.input.activePointer.downTime);
}

I came to the conclusion that this is the best approach when you want to get the duration on press down key because there is not duration attribute in activePointer anymore(Phaser3). So, this code works on Phaser 3 as well.

I hope it helps!
