Enforce low to no updates/ fps, save battery

[MichaelD]

Hello,

 

I'm looking for a way to enforce the least amount of updates and render, I have two buttons that only change their state (up, down). and a timer that sends the status of these buttons.

 

So I'm looking for a way to conserve power because if I have the app running even with a charger attached it manages to run out my battery.

 

Anything I can do to reduce the amount of battery the app is using?

 

Thanks.

I don't know if I fully understand your question, but if you only have two buttons and a status event, you can you use plain HTML/JS/CSS with two buttons and onclick events.

The easy way would be to use this:

this.game.time.desiredFps = 5;

The other way would be to create a main timer and use it to run updates instead of the update method.

The desiredFps doesn't seem to work, I still get 60 FPS I'm also running Phaser.HEADLESS to stop any rendering. The html/css solution is not viable because I'm using other parts of Phaser

I think you'd have to manually run the update loop yourself, stop letting Phaser call it via requestAnimationFrame. Check out Phaser.Game#enableStep and disableStep for updating the game loop manually.

I've seen lots of people complaining about desiredFps not working, but for me it has always worked like a charm. ?

I tried desiredFPS once maybe 8 months ago, it was definitely not working as expected, I looked into the code and it was flawed and broken at that time.  The problem showed itself when you targetted a low value on a device that was already struggling.
