Samples preloading - a visual indication

[tomekslesicki]

Would it be possible to add some sort of a visual indication that the samples are preloading? Like a little blinking two-state button that disappears after they are loaded?

@d-healey Awesome, thank you!

If some of you would like to do a similar thing, here's a code I've ended up with:

// ****** IMAGE PRELOADER ****** //
const var preloadBar = Content.getComponent("preloadBar");
preloadBar.loadImage("{PROJECT_FOLDER}loader.png", "filmstrip");
preloadBar.setImage("filmstrip", 0, 0);

preloadBar.setTimerCallback(function()
{
    this.data.progress = Engine.getPreloadProgress();
    this.setImage("filmstrip", 0, parseInt(this.data.progress * 8) * 14); // number of frames * frame height
});

preloadBar.setLoadingCallback(function(isPreloading)
{
    this.data.progress = 0.0;
    this.set("visible", isPreloading);
	if(isPreloading)
        this.startTimer(50);
    else
        this.stopTimer();
});

The strange thing is that sometimes the animation happens and sometimes only the first frame is displayed. It disappears when the loading is finished so I guess it kind of serves the purpose. I can live with that, but maybe there's something wrong with the code after all?

@tomekslesicki said in Samples preloading - a visual indication:

Could it be that sometimes it's loading really quickly so you're only seeing a quick flash of animation before the panel vanishes?

@d-healey I don't think so, when it doesn't animate, there's just no motion at all.
