lets say i have a table full of CFrame coordinates, and there was a start and a finish CFrame coordinate. the start is permanent, whereas the finish could be any of the other CFrames in the table. how would i make a new table, from start to finish, while effectively drawing a line between as few cframes as possible with as little distance? think of it like connect the dots.

table = {}
om = math.hude

for i = 1,#cframe do
if (starcframe - cframe[i]).magnitude < om then
om = (startcframe - cframe[i]).magnitude
table[1] = cframe[i]
end
end
print(table[1])--will print the closest cframe

that method would normally work, but then it can go anywhere from there and im trying to make the shortest line possible.

math.randomseed(tick())
coordinates = {start={1,1,1}}
mq = ""
nq = ""
ne = 5
for i = 1, ne do
table.insert(coordnates, "r"..i={math.random(1,100),math.random(1,100),math.random(1,100)})
end
repeat
nm = math.random(1, #coordinates)
until nm ~= 1
for q = 1, #coordinates[1] do
nq = nq..q
end
for w = 1, #coordinates[nm] do
mq = mq..w
end
c1 = tonumber(string.sub(nq, 1, 1))
c2 = tonumber(string.sub(nq, 2, 2))
c3 = tonumber(string.sub(nq, 3, 3))
v1 = tonumber(string.sub(mq, 1, 1))
v2 = tonumber(string.sub(mq, 2, 2))
v3 = tonumber(string.sub(mq, 3, 3))
mag = (Vector3.new(v1,v2,v3)-Vector3.new(c1,c2,c3)).magnitude
print(mag)

If you're trying to do what I think you are, that should work, hopefully

Wait, messed up:

math.randomseed(tick())
coordinates = {start={1,1,1}}
mq = ""
nq = ""
ne = 5
for i = 1, ne do
table.insert(coordnates, "r"..i={math.random(1,100),math.random(1,100),math.random(1,100)})
end
repeat
nm = math.random(1, #coordinates)
until nm ~= 1
for q = 1, #coordinates[1] do
nq = nq..coordinates[1][q]
end
for w = 1, #coordinates[nm] do
mq = mq..coordinates[nm][w]
end
c1 = tonumber(string.sub(nq, 1, 1))
c2 = tonumber(string.sub(nq, 2, 2))
c3 = tonumber(string.sub(nq, 3, 3))
v1 = tonumber(string.sub(mq, 1, 1))
v2 = tonumber(string.sub(mq, 2, 2))
v3 = tonumber(string.sub(mq, 3, 3))
mag = (Vector3.new(v1,v2,v3)-Vector3.new(c1,c2,c3)).magnitude
print(mag)

that's better

Put spaces around your less than signs "<". That causes that error.

function getpath(newpoints, start, finish, visual)
dis=100000
points={}
for i, v in pairs(newpoints)do
for q, w in pairs(mypath)do
if w~=v then
table.insert(points, v)
end
end
end
print("1")
for i, v in pairs(points)do
part.CFrame=v
local ray = Ray.new(start.p,(v.p-start.p).unit*500)
local s,p=game.Workspace:FindPartOnRay(ray,tool)
if s==part then
if (v.p-start.p).magnitude < dis then
print("2")

all the ends are in the right places, only it prints 1 in the output, but never prints 2.
