Qt Quick offers graphical and special effects that are very easy to start using. Particles, in particular, are great for gaming apps. You now know how to use the ParticleSystem
to emit an ImageParticle
at a particular angle using AngleDirection
. We examined how Affectors
such as Turbulence
will affect an Emitter
by adding variation to the particle stream.
Gradients
, Glow
, and DropShadows
are useful for bringing emphasis to certain items. The Blur
effects are used to simulate movement action or to add your watermark to images.
In the next chapter, we delve into using something now ubiquitous on mobile phones—touch input. I will also touch upon (pun intended) using other forms of inputs, such as what to do when there is no hardware keyboard and your app is what gets booted into.
