Would it not be better to handle key events with listeners ?

Hi,

I'm currently learning Phaser, and i need to handle key events, so i saw some tutorials and if i want to move my character, i need to know if key is down so, in the "phaser" way, things are done like this:

window.checkInputs = () => {
    
    let key = Phaser.Keyboard
    
     if ( game.input.keyboard.isDown(key.LEFT) )
     {
         console.log('Left is down !')
     }
    
}

And i need to call this method in the update loop, so 60 times / s, phaser will check if left arrow is down, like i come from node.js, i don't like this, i mean it waste resources no ?

So, is this methode better ? :

window.addInput = () => {
    
    document.onkeydown = (e) => {
        if (e.code == 'ArrowLeft')
        {
            console.log('Left is down !')            
        }
        
    }
    
}

 

Thanks !

I would recommend checking out the Phaser's keyboard class.

https://www.phaser.io/docs/2.6.2/Phaser.Keyboard.html

It handles keyboard events and gives you access to other useful functions as well.

Good Luck!

Phaser has both. For continuous input, it's more efficient and accurate to test the key directly. For infrequent events, you can bind to Phaser.Key.html#onDown. There's no need to add your own DOM handlers.
