File I/O - working incorrectly

I'm working on level saving, in the engine i've been working on.
I've created the following functions:

save:

Code:

---

void level::savestaticmesh(char *fname)
{
        remove(fname);

        for (int i=0; i<num_meshs; i++)
        {
                stream = fopen(fname, "a");
                fprintf(stream, "%s %s %s %d %d %d %f %f %f %f %f %f %f %f %f\n",
                        meshP[i].filename, meshP[i].tex1, meshP[i].tex2, meshP[i].textype, meshP[i].repeatx, meshP[i].repeaty,
                        meshP[i].pos.x, meshP[i].pos.y, meshP[i].pos.z,
                        meshP[i].scale.x, meshP[i].scale.z, meshP[i].scale.y,
                        meshP[i].rot.x, meshP[i].rot.y, meshP[i].rot.z);
                fclose(stream);
        }
}

---

load:

Code:

---

void level::loadstaticmesh(char *fname)
{
        stream = fopen(fname, "r");

        while(1)
        {
                int result = fscanf(stream, "%s %s %s %d %d %d %f %f %f %f %f %f %f %f %f\n",
                        tmpfname, tmptex0, tmptex1, &tmptype, &tmprx, &tmpry,
                        &tmppos.x, &tmppos.y, &tmppos.z,
                        &tmpscale.x, &tmpscale.z, &tmpscale.y,
                        &tmprot.x, &tmprot.y, &tmprot.z);

                if(result==EOF)
                        break;

                meshnum++;
        }

        rewind(stream);

        for(int i=0; i<meshnum; i++)
        {
                fscanf(stream, "%s %s %s %d %d %d %f %f %f %f %f %f %f %f %f\n",
                        tmpfname, tmptex0, tmptex1, &tmptype, &tmprx, &tmpry,
                        &tmppos.x, &tmppos.y, &tmppos.z,
                        &tmpscale.x, &tmpscale.z, &tmpscale.y,
                        &tmprot.x, &tmprot.y, &tmprot.z);
                if(tmprx==0)
                        tmprx=1;
                if(tmpry==0)
                        tmpry=1;
                _ceStaticMesh->createstaticmesh(tmpfname, tmptex0, tmptex1, tmptype, tmprx, tmpry,
                        tmppos.x, tmppos.y, tmppos.z,
                        tmprot.x, tmprot.y, tmprot.z,
                        tmpscale.x, tmpscale.y, tmpscale.z);
        }
        fclose(stream);
}

I've run into some trouble though.
Suppose I create two cubes. They each have different texture names, and different positions. I click the 'save' button, and exit the engine. Restart the engine, both cubes are still rendered with different textures; the save appears to have worked correctly. Click 'save' and exit again. Restart, both cubes now have the same texture; the second save messed up.

Just for clarification, the load function reads through the formatted text, and creates a staticmesh entity with the createstaticmesh() function. The function arguments are stored in the array meshP[]. On save, the meshP[] array index is cycled through, and the arguments are read into the file...I'm sure you get the idea.

Any help will be very much appreciated!

Do any of the char arrays you write have spaces? If they do, this could cause problems when you read the file.

You should probably check to make sure you actually read 15 items:

Code:

---

        while (fgets(buf, sizeof(buf), fp) != NULL)
        {
                int result = sscanf(buf, "%s %s %s %d %d %d %f %f %f %f %f %f %f %f %f\n",
                        tmpfname, tmptex0, tmptex1, &tmptype, &tmprx, &tmpry,
                        &tmppos.x, &tmppos.y, &tmppos.z,
                        &tmpscale.x, &tmpscale.z, &tmpscale.y,
                        &tmprot.x, &tmprot.y, &tmprot.z);
                if (result != 15)
                        printf("Error reading file.\n");
        }

why 15?

>why 15?
fscanf and sscanf both return how many items were read. It looks like you are trying to read 15 items.

Ah, gotcha. I though you meant 15 loop cycles :)

>Ah, gotcha. I though you meant 15 loop cycles
I guess what it is I'm getting at, since you said the second save messed up, how many records did it actually write, and were you able to read each line of data back.

It kind of has the feel like one of the reads may have only read a few items, not all 15.

Ran it through the debugger, and everything is reading back, but the texture name values change for some reason??
