Now we can't make it shake forever so we'll define a variable to count how much it has shaken.

Variables, created with 'create var', are able to run a routine when their value satisfies a condition. This lets us set a counter and have a routine run when the count equals 5.

create routine as Start
  launch ball
end

create sprite from 8ball.png as ball
  where x=400 y=300 center=250,250 click=Touched
end

create routine as Touched
  insert into ball where alt=WiggleLeft
  insert into ball where alt=RotLeft
end

create var as WiggleCount where value=0 completion=WiggleDone condition=5 end

create slide as WiggleLeft
  where speed=600 distance=40 direction=220 completion=WiggleLeftDone
end

create slide as WiggleRight
  where speed=600 distance=40 direction=45 completion=WiggleRightDone
end

create rotation as RotLeft
  where distance=20 speed=800 completion=RotLeftDone
end

create routine as RotLeftDone
  insert into ball where alt=RotRight
end

create rotation as RotRight
  where distance=20 speed=-800
end

create routine as WiggleLeftDone
  insert into ball where alt=WiggleRight
end

create routine as WiggleRightDone
	update var WiggleCount add=1
  insert into ball where alt=WiggleLeft
  insert into ball where alt=RotLeft
end

create routine as WiggleDone
  remove from ball where alt=WiggleLeft
  remove from ball where alt=RotLeft
end

create var as lets us name a variable and set conditions for it. In this case, when the value is equal to 5, we run the indicated completion event.
Of course we need to change the value of our variable so each time WiggleRightDone is called, we add one to its value.
Finally, in the completion event for the variable reaching 5, WiggleDone removes alterations that move the sprite. This stops the sprite.

As it is, if you click on the sprite again, it will wiggle forever because we haven't yet reset the variable to less than 5.
