The start project
If you run the
Start Project
option, you should see the basic game screen already in place.
There is no need to repeat the steps we've taken in our previous tutorial to create a batch
node and place all the screen sprites. We once again have a
_gameBatchNode
object and
a
createGameScreen
method.
But by all means, read through the code inside the
createGameScreen
method. What
is of key importance here is that each planet we create is stored inside the
_planets
vec-
tor. And we also create our
_rocket
object (the
Rocket
class) and our
_lineCon-
tainer
object (the
LineContainer
class) here. More on these soon.
In the
Start Project
option, we also have our old friend
GameSprite
, which extends
Sprite
here with an extra method to get the
radius()
method of our sprites. The
Rocket
object and all the planets are
GameSprite
objects.
