Doing so should automatically add an image point. Note that
Imagepoint
has a different
icon than
Origin
. The image point is not the origin; it is simply a place where we can
point to on the sprite. Place the image point outside where you want the green ball to
spawn. This is really handy because this would be much harder to do in other environ-

Now, we are almost ready. Let's go back to our event sheet and find

and find

events.
Let's compare whether
isWave
is to equal to
1
and
ballCount
is equal to

isWave
to
0
. The way this
works is that once all of the balls have been spawned, we need to turn off the spawner. We
do this by setting
isWave
back to
0
.
Your event sheet should look like the following screenshot:
