PIXI.Ticker.system

[Rob Gordon]

Greetings,

I'm trying to understand what PIXI.Ticker.system actually does.

I have experimented with doing the following after initializing my application:

PIXI.Ticker.system.autoStart = false;
PIXI.Ticker.system.stop();

The result is much less energy use (as measured by the Activity Monitor in OSX) and no change in the functionality of the application. The docs mention it's used by PIXI.interaction.InteractionManager (which I use a lot), but all my functionality is intact.

FYI, I'm also stopping the shared Ticker and just using app.ticker for everything at maxFPS of 30.

Thanks,

I may have just answered my own question. It seems the InteractionManager doesn't NEED PIXI.Ticker.system, but can send it events and is set up by default to do so.

You can do this to shut that down:

app.renderer.plugins.interaction.useSystemTicker = false

well it covers one case: when mouse is stationary and object is moved under it. If you dont need that - you can switch it off

I believe the prepare plugin, to upload textures to the GPU, also uses the system ticker, to try and not flood the GPU with tons of uploads all in 1 frame

Right. Don't generally need that (but I can see how it can come up for others).
