meteor->runAction(sequence);

}
2. We grab the next available meteor from the pool, then we pick a random start and
end
x
value for its
MoveTo
action. The meteor starts at the top of the screen and
will move to the bottom towards the city, but the
x
value is randomly picked each
time.
3. We rotate the meteor inside a
RepeatForever
action, and we use
Sequence
to move the sprite to its target position and then call back
fallingOb-
jectDone
when the meteor has reached its target. We finish by adding the new
meteor we retrieved from the pool to the
_fallingObjects
vector so we can
check collisions with it.
4. The method to retrieve the health (
resetHealth
) sprites is pretty much the
same, except that
swingHealth
action is used instead of rotate. You'll find that
method already implemented in
GameLayer.cpp
.
