[solved] Using z pos in a move?

[Nyamaiku]

from the video, i would say the spawner has moved upward, then (not so)slowly moved downward and get stuck to the lower boundary. since you kept the chase in the balls, the balls moved upward towards the enemy.

if you want to make the effect showed in sketchtoy(if i didnt understand wrongly),
make the spawner move just a little upward, not until it reaches the upper boundary, then slowly move downward without moving on the x-axis, while spawning balls until a certain z-axis range.

Yes it would have been easier to make it move on the x-axis, but I wanted to defy the laws of DCing :3

just switching the axis movement is actually almost the same. and achieving this didnt defy any laws of DCing. =-=
