LUA GetTerrain error

[Gandi]

Hi,

 

In my lua code i use

function class:GetTerrain(world)
local terrain
for terrain in iterate(world.terrains) do
 return terrain
end
end

 

in:

 

function class:CreateObject(model)
local object=self.super:CreateObject(model)
local terrain = class:GetTerrain(model.world)
end

 

But i get the error message:

"attempt to call global 'iterate' (a nil value)" at the for-loop.

 

this error occures after i loaded the map where a object of this type exists, or when im adding a new object to my map (but its gone when i placed a road-node once)

 

can anyone help me get rid of it?

are you using:

require("scripts/linkedlist")

 

that is needed for the iterate() function... and its the reason why it doesn't occur when you place a road node, as it uses the linkedlist.lua script

[Gandi]

yes, im using linkedlist..

 

require("Scripts/class")
require("Scripts/Math/math")
require("scripts/linkedlist")

 

the strange thing is, that it also doesnt occur with my object after i placed a road-node.. (also if i deleted the road node again)

It looks like something wrong with including "linkedlist".

 

Try to copy/paste this line from road_node.lua:

require("Scripts/linkedlist")

 

And check paths.
