how can I do this in c++?

[shadmar]

In lua I would do this :

--index which vary on each recurisive run.
local mid=-dim..":"..-df..":"..dim..":"..df..":"..xfactor..":"..yfactor..":"..division..":"..factor..":"..orientation.x..":"..orientation.y..":"..orientation.z

--create model if the index "mid" doesn't exist in table models
if models[mid]==nil then
	model = Model:Create()
    model:SetRotation(orientation)
    models[mid] = model
end

nevermind I kind of solved it

[Ma-Shell]

#include <stdio.h>
#include <unordered_map>
unordered_map<std::string, Model*> models;
...
  
std::stringstream mid_stream;
mid_stream << -dim << ":" << -df << ":" << dim << (...)
std::string mid = mid_stream.str();
if (models.find(mid) == models.end())
{
    Model* model = Model::Create();
    model->SetRotation(orientation);
    models[mid] = model;
}

Edit: meh, 5 minutes too late

Oh yours were much nicer than mine, I used 2 std::vectors one for the text index (I used stringstream) and one to store the models.

Thank you!
