Removal of texture

Hi,

these are very specific questions. It would probably help if you learn a bit more about the Timeline. For instance, instead of using apply, you could use appendTo to schedule a new animation that follows the first. For example, you could fade in and then out again using:

const float kDuration = 1.0f;
timeline().apply( &mAlpha, 1.0f, kDuration );
timeline().appendTo( &mAlpha, 0.0f, kDuration );

You can also specify a delay, so that we wait 5 seconds before fading out. Replace the second line with:

timeline().appendTo( &mAlpha, 0.0f, kDuration ).delay( 5.0f );

You can also add a callback function, which will be called once we’re done fading:

timeline().appendTo( &mAlpha, 0.0f, kDuration ).delay( 5.0f ).finishFn( [&]() { 
    // Do something in this lambda function. Example: just quit.
    quit();
} );

Hopefully with these additional tools under your belt you will be able to animate what you need.
