Another example of a meaningless annoying bug

[Qwertygiy]

Line 3: [lua] local controller = body.VelocityController [/lua]
--Some stuff


Line 14: [lua] function CheckVitalSigns() [/lua]
--Some stuff


Lines 17-20: [lua] if controller == nil then
controller = create("VelocityController")
controller.Parent = body
end [/lua]
--More stuff, including end of CheckVitalSigns


Lines 30-32: [lua]while true do
sleep(0.1)
CheckVitalSigns() [/lua]
--Even more stuff


Lines 46-48: [lua] if not controller then CheckVitalSigns() end
if thedude.Position.x > body.Position.x then
controller.Velocity.x = 5.0 [/lua]

Output: Script:48: attempted index of non-table
