i am trying to write a cob file loader and so far i have managed (with help from nate's ase loader tutorial) to get my program to be able to get basic info from the cob file such as the number of vertices. i can succesfully write a program that reads the file and obtains the correct info but when i go to assign an array of floats, to hold the correct amount of vertices, it won't compile. i have pasted the code bellow. can someone please help me.

            
#include <stdio.h>

#include <string.h>


char fileData[256];
FILE *stream;
int numVertex;
int numTexVertex;
int numFaces;

int main()
{
	if(!(stream = fopen("box.cob", "r")))
	{
		printf("Could not open file. Please make sure it exists.\n\n");

		return 0;
	}

	rewind(stream);

	while(!feof(stream))
	{
		fscanf (stream, "%s", &data);

		if(!strcmp(data, "World"))
		{
			fscanf(stream, "%s", &data);
			if(!strcmp(data, "Vertices"))
			{
					fscanf(stream, "%d", &numVertex);
			}
		}

		if(!strcmp(data, "Texture"))
		{
			fscanf(stream, "%s", &data);
			if(!strcmp(data, "Vertices"))
			{
					fscanf(stream, "%d", &numTexVertex);
			}
		}

		if(!strcmp(data, "Faces"))
		{
			fscanf(stream, "%d", &numFaces);
		}

	}

	float verts[numVertex][3];
	float texVerts[numTexVertex][2];

	printf("Number of vertices = %d\nNumber of TexVertices = %d\nNumber of Faces = %d\n\n", 
			numVertex, numTexVertex, numFaces);
	
	return 0;
}

You can''t size an array with a variable in a declaration, unfortunately. You''ll have to use new.
Here''s what you wrote:

    float verts[numVertex][3];float texVerts[numTexVertex][2];[/source]Here''s how it would work:[source]typedef float tVertex[3];typedef float tTexVertex[2];tVertex *verts = new tVertex[numVertex];	tTexVertex *texVerts = new tTexVertex[numTexVertex];    

( Might be a slight error in the typedefs, but you get the idea )

the compiler most know at COMPILE time how big the array is going to be. You cant use a variable to create an array...
where you have
float verts[numVertex][3];
float texVerts[numTexVertex][2];
cant do that
but you can create it dynamically like this

    struct VERTICE{   float x, y, z;};VERTICE* verts = new VERTICE[numVertex];VERTICE* texVerts = new VERTICE[numTexVertx];    

now just use them like you normally would
then before you exit the program do this
delete [] verts;
delete [] texVerts;

*lol* Looks like we both replied the same thing at the same time.

I am not quite sure of how to implement what you said about the typedefs. How would I store vertices in the array elements? and how would I retrieve them. I tried just going:

            for(index = 0; index < numVertex; index++){	fscanf("%f %f %f", &verts[index][0],                           &verts[index][1],	                   &verts[index][2]);}            

but the compiler complains:

fscanf' : cannot convert parameter 1 from 'char [9]' to 'struct _iobuf *'.

Can you please clear things up for me. BTW thanks for answering my post.

Did you include the FILE* in that fscanf? I forget what param it is (1 or 4) but it must be in there somewhere.

Check out my favorite C standard library reference (also includes source for the functions).

Man do I feel like a dumbass. Maybe late night coding isn''t for me.

MadKeithV can you please modify my code so that it uses the typedefs for I am still unsure of how to do what you said.
