[Lua] If-then always returning false

[Lemonilla]

Maybe some fresh eyes can see what's wrong here.  In the function Write_Map() the 2nd If tree is always providing false, whereas the 3rd works the way it should.  It is suppose to grab the coordinates from pt.txt and then display any that are withing a -7 -> 7 (y) and -7 -> 7 (x) area around you (at pos.x , pos.y , pos.z).  It works for everything accept displaying a point from pt.

There should be rings of points.

Code: [Select]

args = {...}
pt_length = 0
pos = {}

  local mult = 10^(idp or 0)
  return math.floor(num * mult + 0.5) / mult

pt = {}
local k = 1
for v in string.gmatch(s, "([^\n]+)") do
if v ~= nil then
if v ~= "\n" then
pt[k] = { a = v }
pt_length = pt_length + 1
k = k + 1
end
end
end
end

local k = 1
local tak = pt[b].a

[Lemonilla]

It turns out that the values in pt were saved as strings, so the statement was comaring strings to numbers and coming out false.  to fix this I used

Code: [Select]

if tonumber(x) == tonumber(pt[a][1]) then
if tonumber(y) == tonumber(pt[a][2]) then
if tonumber(pos.z) == tonumber(pt[a][3]) then
io.write("X ")
w = 1
end
end
end

Glad CH was able to help you.

This tends to happen a lot.  I'll post a question, and then 5-10 min later, when I go away to do something else, I'll come up with an answer.

[Geek-9pm]

Yes, no charge for out service.
Come back often.

You successfully rubber-ducked the problem.
