Script that moves to target named Zombie?
Okay, so I'm not entirely sure if these questions are allowed, but if they are, feel free to reply. This is not my script. It is one I have found from a model, I wish to edit it so I can learn better and I feel it would really help me if the community could help me with a thing or two about the script I found and some things I've had trouble locating in the wiki.
Thank you so much ( I commented on the things I don't understand, the rest I get ):
local larm = script.Parent:FindFirstChild("Left Arm")
local rarm = script.Parent:FindFirstChild("Right Arm")
function findNearestTorso(pos)
local list = game.Workspace:children()
local torso = nil
local dist = 1000
local temp = nil --Why make a variable for nil?
local human = nil -- ^^
local temp2 = nil -- ^^
for x = 1, #list do
temp2 = list[x] -- What exactly is the [x] for? Is this restating or..?
if (temp2.className == "Model") and (temp2 ~= script.Parent) then
temp = temp2:findFirstChild("Torso")
human = temp2:findFirstChild("Zombie")
if (temp ~= nil) and (human ~= nil) and (human.Health > 0) then
if (temp.Position - pos).magnitude < dist then
torso = temp -- nil to nil? do not understand
dist = (temp.Position - pos).magnitude
end
end
end
end
return torso
end
Again, thanks. Just a few things I pointed out and hope you can clarify. Cheers :)

local larm = script.Parent:FindFirstChild("Left Arm")
local rarm = script.Parent:FindFirstChild("Right Arm")
function findNearestTorso(pos)
local list = game.Workspace:children()
local torso = nil
local dist = 1000
local temp = nil --These are made nil because the part that they refer to later in the script isn't in the game at the beggining. These aren't really even needed here, the script should work fine without declaring these variables nil.
local human = nil
local temp2 = nil
for x = 1, #list do
temp2 = list[x] -- The x is used to find the part in the table (If you don't understand "for" functions, look at this page: http://wiki.roblox.com/index.php?title=Generic_for). Anyways, it finds the children in the table that was created on line 5 and changes the variable "temp2" from nil to the child.
if (temp2.className == "Model") and (temp2 ~= script.Parent) then
temp = temp2:findFirstChild("Torso")
human = temp2:findFirstChild("Zombie")
if (temp ~= nil) and (human ~= nil) and (human.Health > 0) then
if (temp.Position - pos).magnitude < dist then
torso = temp --This isn't "nil to nil". If you look on line 14, temp is the character's torso. The script is changing the "torso" variable from nil to the character torso.
dist = (temp.Position - pos).magnitude
end
end
end
end
return torso
end
I edited what you wrote and did my best to explain what I could...If you have any further questions, please leave a comment below. Hope I helped :P
