efects in special move

[A-Man]

So nobody replied till now. Oh well, I guess i asked a similar question last week, so next time please search first, then post if u didn't find the answer.So now, all wat you have to do is:
1- Opoint 2 state 3000 balls, one in the very left of the screen and the other one in the very right of the screen.
2- Add hit_j: 1 in each ball; this will make go toward the inside of the screen(in the z axis) behind all the characters and objects (as a background)
3-Now, let the 2 balls opoint a kind5 object with a state 9997(the background picture).

I guess this shall work.
