@Jonforum iirc, the ticker class was one of the more recent addons to pixi, how far back was it added in? I want this plugin to be usable in all versions of MV, which is why I've opted for using the FPS meter, in the first place, also the code you provided would need a little bit of an adjustment. As pixi Tickers have to be started, or they don't ever execute.
PHP:
var ticker = new PIXI.tickerTicker();
ticker.add( function() {
// Also I'd more than likely use ticker.elapsedMS,
// as it returns the amount of latency direcetly.
console.log( ticker.elapsedMS );
}.bind( this ) );
ticker.start();
However, I don't see much use in changing it, as FPS meter is not removed automatically in a MV project, so the fps meter is indeed, still valid on an exported project, the only way it would not work, would be if someone manually removed the fps meter after exporting the game, and removed it's references from rpg_core.js as well.
Edit : thanks for the feedback though
@Jonforum , it might be a bit more stable, and less code, I'll have to play around with it a bit, I'll be sure to give you a mention if I do opt for a pixi ticker instead.
