The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

problems with initializing my map

6 posts in this topic

Hey guys,
so I am working on a simple level editor for a platform game I'm making, and everything's been going smoothly up until now.
I decided I wanted to have a 3d vector to allocate tiles for my editor instead of a 3d pointer because they are very difficult to understand( for me anyway). The level allocates correctly ONLY if the width, height, and layers of the level are all the same value, and that is what is stumping me.
I would greatly appreciate it if someone could help me out.
 
//My vector container
vector<vector<vector<Tile*> > >map;

//How I'm allocating the map... in the Level constructor
Level::Level(int tileWidth, string tilePath)
{
	AskProperties();
	AskFileName();
	sheet.Init(tileWidth, tilePath);
	
	for(int l = 0; l < layers; l++)
	{
		map.resize(layers);
		cout << "Layer " << l << endl;
	
	for(int i = 0; i < height; i++)
	{
		map[i].resize(height);
		cout << endl<< "Row " << i << endl;
		for(int t = 0; t < width; t++)
		{
			map[i][t].resize(width);
	     	map[i][t].push_back(new Tile(t * sheet.GetTileSize(), i * sheet.GetTileSize(), false, sheet));
		    cout << "X " << t << endl;
		}
	}
	}
	
	
	

}

//How i am saving the level -- using integers to represent tile types
void Level::Save()
{
	
	cout << "NOPE" << endl;
	ofstream file(fileName.c_str());
	for(int x = 0; x < layers; x++)
	{
	file << endl << endl << "Layer: " << x + 1 << endl << endl;	
		for(int y = 0; y < height; y++)
		{
			file << endl;
			for(int z = 0; z < width; z++)
			{
				file << map[x][y][z]->GetType();
			}
		}
	}
	
}

I tried that, and it had the same result as before. It only works when the width, height, and layers are all the same. When, for example, i set the width and height to 10, and the layers to 3, it returns an error that says: vector subscript is out of range.

Thank You Brother Bob. I still have much to learn. rolleyes.gif But then again, we're never done learning are we?

If you resize in the 'i' loop, instead of reserve, you don't need to push back, you can just use the indices directly map[l][i][t];

 

Probably makes it clearer what is going on.

 

Virtual spanks all round for using lower case L as a variable name, looks too much like the number 1. (EDIT: I'd use layer, row, col instead for the index variables I think).

 

I'm not jumping for joy about naming the array vector3 'map' either, since that is also the name of a class in namespace std.
