Writing a Program for loading Maps

[sli]

Have you considered that the values might be in reverse endian?

For example, you say you're getting 3,000 million textures (3 billion). The maximum value of four bytes is 4,294,967,295 (that is, FF FF FF FF). Not too far from 3 billion. In fact, 3 billion in hex is B2 D0 5E 00. However, if you reverse it (00 5E D0 B2) you get 6,213,810. The reason I point this out is because while 00 00 00 01 is only 1, 01 00 00 00 is 16,777,216.

In short: try reversing your four byte texture count buffer and see what you get. If it works, you'll want to make sure you reverse ALL numerical values.

(Look, guys! I didn't flame or anything! I ran into this problem when hacking ZSNES save states back when I was like... 14. I kept wondering why Ness had 6,144 HP at level 1.)

Hm it doesnt seem to be this either...

Look I got some Screens



The first one is when I try to get the texture count.
There you may see that the Size is changing aswell and the Bitmaps aren't correctly displayed anymore

In the second one you see that I removed the texture count and the Size and Bitmaps are correctly displayed again.

The code is here:

Code: Select all

char* buffer;
	unsigned int count;


	ifstream File("data\\payon.rsw");
	ifstream GND("data\\payon.gnd");
	ifstream GAT("data\\payon.gat");
	streamoff curpos = 0;

// Header
	GND.seekg(0);
	buffer=new char[4];
	GND.read(buffer,4);
	curpos += 4;
	cout<<"Header : "<<buffer<<endl;
	delete buffer;

	// Version
	//GND.seekg(curpos);
	//buffer=new char[2];
	//GND.read(buffer,2);
	curpos += 2;
	//cout<<"Version : "<<*((char*)buffer)<<endl;
	//delete buffer;

	// Size X
	GND.seekg(curpos);
	buffer=new char[4];
	GND.read(buffer,4);
	curpos += 4;
	cout<<"Size X : "<<*((int*)buffer)<<endl;
	delete buffer;

	// Size Y
	GND.seekg(curpos);
	buffer=new char[4];
	GND.read(buffer,4);
	curpos += 4;
	cout<<"Size Y : "<<*((int*)buffer)<<endl;
	delete buffer;

	// Proportion
	GND.seekg(curpos);
	buffer=new char[4];
	GND.read(buffer,4);
	curpos += 4;
	cout<<"Proportion : "<<*((float*)buffer)<<endl;
	delete buffer;

	// Count
	//GND.seekg(18);
	//buffer=new char[4];
	//GND.read(buffer,4);
	curpos += 4;
	//cout<<"Count : "<<*((int*)buffer)<<endl;
	//delete buffer;

	// Size
	GND.seekg(22);

	delete buffer;

	//Textures
	for (int i=0;i<26;i++){
