Movie Script

on startMovie()
  spr = channel(1).makeScriptedSprite(member("shape"))
  scr = script("moveSprite").new()
  spr.scriptInstanceList.add(scr)
end

  go(the frame)
end

Behavior - script("moveSprite")

property speed

on new(me)
  speed = random(10)
  return me
end


on exitFrame(me)
  if(sprite(me.spriteNum).locH > 300) then sprite(me.spriteNum).locH = -30
  sprite(me.spriteNum).locH = sprite(me.spriteNum).locH + speed
end
