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.

Melee, Spell-casting, Item Use

Did some more work on codifying the actions and skills system. I took out the old melee code, and implemented a more general structure for executing an action. All actions are now described by a table of data, and a combatant can be commanded to execute an action. For example, a melee attack currently looks like:



testmelee=
{
movementcost=3,
nocastonblock=true,
needslos=true,
range=1,
animation="Melee",
needstarget=true,
castonself=false,
arearadius=0,
execute=function(self,creator,world,args)
local targetid=world.hex:getObjectID(args.targetx, args.targetz)
if targetid<0 then return end
local target=world.objects:getObject(targetid)
if target==nil then return end
local amount=rnd:getRange(1,20)
world:combatLogMessage("#11 Entity "..creator.guid.." #13 hits #12 Entity "..targetid.." #13 for #10 "..math.abs(amount).." #13 damage.")
target:handleMessage("ModifyLife", {amount=-amount})
end
}


The preliminary data describes how it should be targeted, who it can affect, whether or not it requires an actual target to cast it upon, if it can be cast upon friendlies, how large an area it affects, what the maximum casting range is, movement cost. When the action is actually performed, the execute() function is called.

By contrast, here is the action descriptor for TestFireball:


testspell=
{
movementcost=3,
nocastonblock=true,
needslos=true,
range=-1,
animation="Cast",
needstarget=false,
castonself=false,
arearadius=1,
execute=function(self,creator,world,args)
local target=world.hex:calcTileCenter(args.targetx, args.targetz)
world:spawnTestProjectile(creator, target.x, target.y)
end
}


At this point, it's a simple matter of implementing the various assistant components. Just now I implemented (or re-implemented, I should say, since it's based on the original real-time GC version) the PeriodicAreaHeal component. At the beginning of each round, the periodic entities go first and perform their heartbeat actions. PeriodicAreaHeal pulses a heal out to any friendlies within its radius. In the above screenshot, the area heal has just healed a player unit. PeriodicAreaDamage will operate in a similar fashion. Other components to be re-implemented today include the DirectHeal and DirectDamage components, in order to add an actual damage or heal payload to projectile objects and other types of objects.

I do need to settle down and really put brain to paper on the combat system and character stats. All of that is still the placeholder stuff from the original GC.

I also spent a bit of time working on the ashlands tile set, used for volcanic islands:

Throw some volcanic peaks in there instead of the brown and snow-capped mountains, and render some black, leafless, skeletal tree trunks, and I think it would look pretty good.

Where do you find the time to work on this?!?
Since my son was born, I barely have time to sleep and eat...
Anyway, I think you're doing a good job with GC
