[request] C++ coder help

(1/1)

flagg78:
Hi all. i have an odd problem and need some assistance from a coder. I have reason to think there is a bug with the 3dstexmover program. i think it is having a problem when saving the model at the end. everything runs fine but the file size is reduced to zero. if someone has a chance and they could look at it that would be awesome! I think its in c++ but im not a coder. thanks for any help you can give.

--- Code: ---#include "modelheaders.h"
#include "lib3dsmesh.h"
#include "lib3dsfile.h"

ModelHeader *header;
ModelVertex *vertices;
ModelVertex *dVertices;//==dummyvertex
int nVertices;
int FileSize;
char *m2;

void write3ds(Lib3dsFile *f)
{
int i,meshV,meshNum;
Lib3dsMesh *m;

nVertices=0;
int nSubmeshes=0;


printf("Loading 3ds Filen");

for (m=f->meshes; m; m=m->next)
{
nVertices+=m->points;
nSubmeshes++;
}

//Load initial vertex & triangle data
meshV=0;
meshNum=0;
for (m=f->meshes; m; m=m->next)
{
printf("Processing Mesh %dn",meshNum);
meshNum++;
for(i=0;i<m->points;i++)
{
m->texelL[i][0]=vertices[i+meshV].texcoords[0];
m->texelL[i][1]=1-vertices[i+meshV].texcoords[1];
}
meshV+=m->points;
}

}

void load3ds(Lib3dsFile *f)
{
int i,meshV,meshNum;
