What just happened?
We created our first particles. ParticleDesigner exports the particle system data as a
.plist
file, which we used to create our
ParticleSystemQuad
objects. You should
open one of these files in Xcode to review the number of settings used in a particle system.
From Cocos2d-x you can modify any of these settings through setters inside
ParticleSystem
.
The particles we'll use in this game are as follows:
•
_jet
: This is attached to the
_rocket
object and it will trail behind the
_rock-
et
object. We set the system's angle and source position parameters to match the
_rocket
sprite.
•
_boom
: This is the particle system used when
_rocket
explodes.
•
_comet
: This is a particle system that moves across the screen at set intervals and
can collide with
_rocket
.
•
_pickup
: This is used when a star is collected.
•
_warp
: This marks the initial position of the rocket.
•
_star
: This is the particle system used for the star that the rocket must collect.
The following screenshot shows these various particles:
