      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. 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.

RPG Weapon Stats

3 posts in this topic

I have a weapon generator for a 2D roguelike RPG I am developing. It has variables that store the name of the weapon, the base damage output, the base attack speed, the required strength to equip, and the gold value of the weapon. For example.... A Short Sword could have 5 base damage, and 3 attack speed with 10 required strength to equip and a gold value of 200. But what would be a good way to add weapon "levels"? So the damage would be greater if the level was higher. I don't want the attack speed to change but what would be a good equation to use to increase the damage, required strength, and gold value of the weaon if the weapon is of a higher level?

One possible way is to add a level scaler variable such that when you create the weapon variable, you would supply it's level along side with its power, requirements etc. All its attack or level sensitive data would be multiplied or added to the level scaler. For example, the attack would be: [code]attack = level*(attack_increase_per_level) + baseAttack[/code] You may also use this on other variables so that it scales with level. You might want to add a [code]levelUp()[/code] function to the weapon so that you can change the level.

I can give you an example for the multiplier. In this example we add 0.1 for each level, but you can change it with whatever you want. Of course this would be a linear incresing, but they're simple maths, and I hope you can do it with this example.

level1 - multiplies by 1
level2 - multiplies by 1.1
level3 - multiplies by 1.2
and so on

we can see we add (level-1)/10 to the base multiplier, which is 1. So we got it:

1+(level-1)/10 = (9+level(/10


[code]int multiplier = (9+weaponlevel)/10;
attack = damage_it_should_do*multiplier[/code]


That's an example, I hope it helped.

There are numerous ways this can (and has) been done. One way is as suggested above to simply multiply the level by a value and add it to the base stat. You could have different multipliers for each stat, or you can base certain stats (such as gold) off the others.

Instead of a simple level, you can have descriptive tags that get added to items, each tag having its own modifiers. Examples include material ("Mithril knife", where "mithril" has +2 damage and +500 gold), a quality ("Well-balanced cudgel", +1 speed, +1 damage, +20 gold), or magical ("Katana of Destruction", +10 damage, +10 min strength). Certain tags can get mixed for powerful items: "Epic Dragonbone Spear of Slaying Rodents". In this scenario, tags are statically defined, but added randomly to items during generation.

Expanding on the "tag" system, you could have special items ("runes", "enchantments", etc.) that get added to items to enhance their effect. Items only get a certain number of "slots" for enhancements. This could be a form of rudimentary crafting, where enhancements can only be added to items at special places (e.g. a forge) or by certain NPCs.

Whichever path you choose, you are going to want it to be easily tweakable - balancing these types of games can be a major (oft times seemingly impossible!) task. Keep all multipliers, tag modifier data, etc. in a [i]single place, separate from your logic that uses them, [/i]and somewhere that it can be easily changed, like a config file or a section of static code.
