Assimp Unhandled Exception when importing .obj - c++

Question

I've been trying to get Assimp to work correctly for the past two weeks, to no avail, so I decided asking here was the best thing to do. I followed thecplusplusguy's tutorial on importing static meshes, and I've copied it word for word in an effort to get it to work.
When I try to import an .obj (a cube, if that matters) it says I have an "Unhandled exception at 0x00EF061B in OpenGL.exe: 0xC0000005: Access violation reading location 0xABABAFFB", it stops the program and tells me it's on line 30 of my code ( "for(int i=0; imNumMeshes; i++)" ).
#include "sceneloader.h"
sceneLoader::sceneLoader(){
std::cout<<"New scene created."<<std::endl;
}
sceneLoader::sceneLoader(const char* filename){
std::cout<<"Scene loading hath begun."<<std::endl;
Assimp::Importer importer;
const aiScene* scene = importer.ReadFile(filename,aiProcess_GenSmoothNormals | aiProcess_Triangulate |
aiProcess_CalcTangentSpace | aiProcess_FlipUVs |
aiProcess_JoinIdenticalVertices);
if(scene->mFlags == AI_SCENE_FLAGS_INCOMPLETE){
std::cout<<"MFLAGS - Scene '"<<filename<<"' could not be loaded."<<std::endl;
return;
}
if(!scene->mRootNode){
std::cout<<"MROOTNODE - Scene '"<<filename<<"' could not be loaded."<<std::endl;
return;
}
std::cout<<"Recursive processing about to begin."<<std::endl;
recursiveProcess(scene->mRootNode,scene);
std::cout<<"Recursive processing finished."<<std::endl;
}
void sceneLoader::recursiveProcess(aiNode* node, const aiScene* scene){
//process
for(int i = 0; i<node->mNumMeshes;i++){ //HERE IS THE PROBLEM
aiMesh* mesh = scene->mMeshes[node->mMeshes[i]];
processMesh(mesh,scene);
}
//recursion
for(int i = 0; 0<node->mNumChildren;i++){
recursiveProcess(node->mChildren[i],scene);
}
}
When I've added couts to debug it, the "scene->mNumMeshes" returns 1 (which it should, since it's one cube), but "node->mNumMeshes" returns 0.
I understand that an unhandled exception occurs when there's a null pointer, and that the null pointer here is the "node->mNumMeshes", but why is it null? And how would I fix this?

Answer 1

My bad.
There was a typo:
void sceneLoader::recursiveProcess(aiNode* node, const aiScene* scene){
//process
for(int i = 0; i<node->mNumMeshes;i++){
aiMesh* mesh = scene->mMeshes[node->mMeshes[i]];
processMesh(mesh,scene);
}
//recursion
for(int i = 0; 0<node->mNumChildren;i++){ //IT SHOULD BE AN i INSTEAD OF A ZERO
recursiveProcess(node->mChildren[i],scene);
}
}
Finished code looks like this:
void sceneLoader::recursiveProcess(aiNode* node, const aiScene* scene){
//process
for(unsigned int i = 0; i<node->mNumMeshes;i++){
aiMesh* mesh = scene->mMeshes[node->mMeshes[i]];
processMesh(mesh,scene);
}
//recursion
if(node->mNumChildren > 0){
for(unsigned int i = 0; i<node->mNumChildren;i++){
recursiveProcess(node->mChildren[i],scene);
}
}
}
Sorry.
Won't happen again.
