I'm working on a simple platformer in my spare time with Phaser 3 and I'm currently working on trying to tighten up my controls. Currently I'm trying to prevent jump spamming so that every jump is an intentional action taken by the player. One press of the jump button should translate to only one jump being performed (ie, key must be released to jump again). Looking at the `Key` class, each key has a property of interest: `_justDown`. This appears to be the property I should use, however it's always `true`. Digging into the source code for v3.1.0 the only time this property is modified is during the process event (`ProcessKeyDown`) and when manually checking using `JustDown`: function create () { this.cursors = this.input.keyboard.createCursorKeys(); } function update () { if (Phaser.Input.Keyboard.JustDown(this.cursors.up)) { // Do some jumping } } This seems to work--sort of--except `ProcessKeyDown` gets called repeatedly and resets the property.. Is there an alternate approach I should be using? I know I could use a jump timer but that seems like a hack. Perhaps this scenario is simply a bug with Phaser at the moment?

I've been struggling to figure out if the "_justDown" property of a key is working properly or not. It seems to always be true as long as the key is held just like "isDown" when accessed directly (ex: someKey._justDown). It seems that the intention is to use the Phaser.Input.Keyboard.JustDown() getter method, but it returns the same results as key.isDown and key._justDown (ex: Phaser.Input.Keyboard.JustDown(someKey)) If this is a bug then I'm comfortable enough to try and make a fix, but I figured I should first see if I'm misunderstanding how to use it in the first place.
