I need help in finding/ and or Making Scripts

[Paradox]

♦ Power-Ups Scripts (I need help with the Power-Ups e.g. Speed, 2x Damage Etc.)

That should be really easy. Something like
[lua]
box = script.Parent
player = hit.Name

function onCollide(hit)
game.Players.player.Speed = 8.0 --Can be changed to desired speed
sleep(10) --Time Powerup lasts (seconds)
game.Players.player.Speed = 4.0
end

link(box.Collided, onCollide)
[/lua]
