Persist keyboard events between states

[GameDemon]

Is it possible to persist keyboard events between states? I am setting one with `game.input.keyboard.addKey()` and `myKey.onUp.add()` in the first state `create` function, but changing states seems to remove the listener.

 

I'm using 2.4.4, but can't find the documentation for what occurs between state transitions, is this available somewhere?

 

Thanks in advance

AFAIK it's not possible, no. I just end up re-binding them on state transition.

Thanks Dr! I was looking at that file but managed to miss that line 

 

Hm… can I ask if there is a good pattern or best-practice for storing logic/methods outside of the various game states, so that it doesn't have to be redeclared? Are people extending Game?

I'd love to hear other people chime in but here's what I do (not authoritative! not a best practice or anything! just what works for me!)

 

If it's something that needs to be a part of the update or render cycle I make a Phaser.Plugin. Anything that manages tweens, or ensures timings between events, even particle effects, that kind of thing... I tend to make those Plugins. Most of those plugins make themselves properties of the game instance.

 

If it's just a collection of stuff that would be handy to reference elsewhere I make an object and stick it on the game instance, too.  For example, every layer in my game is hung off a "groups" property on the game instance.

Thanks a lot for your detailed answer Dr, I should probably make it a separate thread because it's an interesting topic and people might not find your post here.
