The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development.

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.

Implementing Objects with specifications

Hello, I have class Weapon:

[code]class Weapon {
private String name;
private int min_damage;
private int max_damage;
private int weight;

public Weapon(String name, int weight) {
this.name = name;
this.weight = weight;
}

public int getMinDamage() { return min_damage; }
public int getMaxDamage() { return max_damage; }

public void setMinDamage(int x) { min_damage = x; }
public void setMaxDamage(int x) { max_damage = x; }

}[/code]

and I want at beginning of the program to create three weapons like longSword, shortSword, saber, each of it would have parameters min_damage, max_damage, name and weight, so how I need to create them? I am thinking about two ways, first:

[code]Weapon longSword = new Weapon("Long Sword", 10);
longSword.setMinDamage(5);
longSword.setMaxDamage(10);[/code]

second:
[code]class longSword extends Weapon{
// same actions like upper
}[/code]

but I realise, that both methods are wrong, maybe you have any advice for java programming newbie? Thank you in advance :)

I would go for the first method, but with the modified class bollu suggested.

Are you planning to store the stats of the weapons in a text file? or a database? or an xml file? Seems the first method would work nicely with any of those.

If different swords don't need different attributes or behaviour, do not add separate Java classes for them.
For keeping them apart, for rendering for example, you could use enums instead of strings.

Thank you [b]bollu[/b] for fix, [b]mickd, [/b]thisis my other question, I noticed, that most of people store data in xml files, but my game will be really small, it will only containt 3 weapons and 3 armors also 2 players (human and computer), so maybe there is a way just to implement them all dinamically while game starting just with Weapon longSword = new Weapon("Long Sword", 10); without storing data somewhere[b]? 6510, [/b]abilities of the swords are the same, different only stats, same with armors, maybe you can give any example? I have been searching for it, but I did not find any simple ones. Because it is just my first java game at all and it will be simple for the first time. After finishing I will bring it here as object to learn :)

Something like this:

public enum WeaponClass {
LONG_SWORD, SHORT_SWORD, MAGIC_SWORD;
}

public class Weapon {
private enum WeaponClass weaponClass;

[color=#000088]public[/color][color=#000000] [/color][color=#660066]Weapon[/color][color=#666600]([/color]WeaponClass weaponClass[color=#666600],[/color][color=#000000] [/color][color=#000088]int[/color][color=#000000] weight, int minDamage, int maxDamage[/color][color=#666600])[/color][color=#000000] [/color]{
...
}
}

Only if you have use of it...
