Post news RSS June Update

This month I've moved on from the lighting system that's been the focus of development in previous months, onto getting characters into the game and moving around. The goal of the first playable prototype is to have dwarves in the game as a playable race, before working on bringing other races in.

First of all, it's with great pleasure that I can unveil the first piece of concept art for King under the Mountain, produced by Anthony Avon. As something of a specialist in landscape concept art, I contacted Anthony with a description of the game, the setting, and a brief of producing a landscape depicting a dwarven settlement in the game world.

Concept art of a dwarven settlement


The artwork is actually meant to show different stages of the development of a settlement in the game - towards the foreground you can see simple structures for mining and a sawmill, the focus of the picture are dwarven buildings that would be constructed while the centerpiece in the background of the fortress set into the mountainside is the end goal. As part of what ended up being quite a large undertaking, Anthony first worked on some black and white concepts to feed into the final color piece.

Although the game is top-down 2D, these concepts will greatly help to set the look and feel of assets produced for in-game. I'm extremely happy with how the artwork has turned out and can't wait to see what Anthony produces next for the game! Don't forget to check out his artstation site at Artstation.com.

Before I started work on the AI systems which will drive a lot of the gameplay, I wanted to get some working graphical assets in place for dwarven characters rather than use abstract shapes or placeholder art. After contacting several 2D artists with a brief of requiring a few dwarven characters in a simple vector style (with no legs) I've decided to go with those produced by Dave Rigley shown below. Dave doesn't have an online presence yet but given the quality of his work I hope that he does soon!

Getting the characters into the game was complicated by the fact that I want the skin and hair colors to be dynamically colored (and open to mods) separate to the other parts making up the body. This can be done by separating the characters into different layers, but to complicate matters further, they can end up facing one of several directions which has some further implications for what is drawn when. It took some time but there's now a relatively simple, moddable system for defining parts of a character with the ability to color in different parts independently. I plan to carry this design on into most of the objects used in the game to allow a huge variety of colors and styles without requiring extra artwork to be produced.

With these in place I could finally start work on the AI behaviours of the dwarves in the game which is probably one of the most important parts of the game's implementation. For now, I've really only focused on path-finding and path-following. As ever, the excellent tutorials by Amit Patel of Red Blob Games were a huge help, thanks Amit!

Path-finding is a relatively mature and well-understood problem in game development so I had a wealth of experience to draw from. Although I've ideas for further improvements and refinements, for now the pathfinding is calculated by using good old A*. Despite the surface simplicity of the algorithm, running it over a large map or for a large number of game characters can significantly impact performance/framerate. I've come up with a multi-threaded solution which will use multi-core processing (as all game rendering and most updates tend to run on a single processor), which has allowed me to run the game in its current state with tens of thousands of dwarves without significant slowdown! As the final game will probably have at most dozens or hundreds of dwarves in a single settlement, this should do :)

Since getting the dwarves able to figure out a path to follow, actually following the path, at the same time as trying to avoid each other and not clip through walls, is another matter! Although still in progress I've got to a point I'm happy with and able to share an example video of it all put together in action


The dwarves in the video have a dynamically-chosen beard color based on one of several shades. The plan is for this and their skin color to be even more randomised for more procedural content. This video does not have lighting applied, shadowing of characters and outdoor lighting is something I hope to get onto in the near future. For now, I'm going to keep working away at the character movement. See you next time!

i have a few ?s as the game looks like something i would want to play as i do like settlement/ base building games.

1.Are there are factions in the game and if so do we unlock them or can we play all of them from the beginning

2. is there going to be any real time stragey combat since the settlement your building you will have to build a barracks and stuff if so that would be nice

Thanks for the questions!

1. Yes there's different factions and they'd all be available from the start of the game! Currently planned are Dwarves, who work as a kind of communal clan "for the greater good", humans who will be a bit trickier to play as each settler works for money, so the player will have to set taxes and wages and maintain a functioning currency. Also orcs, who rely more on raiding other settlements for food and resources, and have to be kept happy by being part of enough fights or else they'll turn on each other :) If/when I can launch this on Kickstarter or other crowdfunding platforms, I'd like to include more weird and wonderful factions as a stretch goal, such as playing as a necromancer raising hordes of undead servants to do your bidding, and other more "evil" factions inspired somewhat by Dungeon Keeper.

2. The grand plan is you'll be able to visit and attack other player's settlements - actually a copy of their settlement uploaded to the central server - with a party of adventurers who have grown out of your town guard / barracks. Combat is planned to be turn-based on a grid, somewhere between XCOM and pan and paper RPGs. Both players may gain rewards for playing in this way - the settlement under attack wouldn't actually lose anything - it's not going to directly affect the player's settlement as in something like Clash of Clans.

oh ok yeah im going to totally pick this game up when i can the turn base (as a person who mostly prefer real time)mostly play it for the base building as it does look fun might not fool around with the warring side do to me favoring real time might try it out from time to time
