read acces error on vector=...
Author
I have a simple line of code but i keep on getting read acces errors there and i have no clue why.
I have a vector of a vector(vector< vector <int> >) and want to get one of those int-vectors seperated(vector<int>=vector< vector <int> >) and that's exactly where the error happens.
the code:
std::vector<int> adjFaces=adjacentFaces[vertexindex]; //read acces violation!
this line is in a loop and the error occurs when vertexindex is 260, the line worked without an error for other indices.
adjacentFaces is ca 1500 elements large.

You should prolly be obtaining a reference to the vector you are getting from the 2D array not a value copy.

ok that error is fixed but now get a user breakpoint error on a line that just contains a "}".
Where could that come from?
The call stack:
calculateNormals is the function in which the compiler says the error occured on "}"
the calclulateNormals function:

The call stack:

the calclulateNormals function:
void ngMesh::calculateNormals(){ //ok the follwing function is not really the perfect way of getting vertexnormals(does it all multiple times per vertex) but at least it (should) work(s) int sz=Indices.size(); vertexnormals.resize(Verts.size()); for(int i=0;i<Indices.size();i++) { short index=Indices; std::vector<ngTriangle> adjFaces=adjInfo.getAdjacentFaces(Indices); ngVector3 avgNormal(0.0f,0.0f,0.0f); for(int j=0;j<adjFaces.size();j++) { avgNormal=avgNormal+adjFaces[j].getNormal(); } int size=adjFaces.size(); avgNormal=avgNormal/size; vertexnormals.x=avgNormal.x; vertexnormals.y=avgNormal.y; vertexnormals.z=avgNormal.z; } //User Breakpoint error?! wtf? }regards,

Where could that come from?
Usually from the destructor of a local variable of automatic storage duration.

a variable of automatic storage duration?
does that mean a variable which is automatically deleted after needed?
and why is there an error? where's the problem with that?
