Drunk On Nectar releasing on Steam Q4 – 2016

Drunk On Nectar was Greenlit on Steam last month and with this huge milestone realized, release plans are now in full swing!

After careful consideration I’ve decided to postpone release to Q4 – 2016. This provides sufficient room for polishing the current product to meet the expectations of DoN’s enthusiastic supporters on Steam, while also providing the opportunity to add new content to the game. It will be an Early Access release, the enormous scope that a full-fledged nature game represents necessitates that.

Finally, this IndieDB article I’ve written goes into much greater detail about all of this (along with a ton of new pics!) so be sure to check that out while you’re here!

DoN – Your ultimate Nature Sandbox is almost there!

Beauty Dragonfly Slider

It’s been a while since I last posted but rest assured, the only reason for that is how deeply entrenched I’ve been in taking DoN along towards completion.

And on that front, I have great news to share! DoN’s first playable build is almost ready for gamers to dive into and with that, Steam Greenlight submission is now imminent.

I’ve gone into more detail on all of this in this new article I wrote on IndieDB so be sure to check that out, there’s a bunch of new screenshots I’ve posted in there as well.

That’s it for now, I hope to see you play the game on Steam some day soon 🙂

 


Spider AI hunting and new gameplay mode!

Finally, Spider AI for DoN is ready! This proved particularly challenging because I had to write a custom pathfinding system again (this time for land based creatures). I was hoping to use Unreal’s native navigation for this but understandably it’s geared more towards humanoids (so it doesn’t work beyond 90 degree slopes and slender foliage like plant stalks are not covered even with maximum cell precision settings).

In another important development, DoN has a new game mode!

Combat Survival is a game mode where players can quickly jump into short timed matches with simple objectives (eg: survival for prey, a successful hunt for predators). In the short-term, this game mode will be the primary focus of the game until I’ve built enough momentum to carry the core nature simulation work forward again.

I’ve written a detailed article about this change in direction on DoN’s IndieDb page, so be sure to check that out as well. (I didn’t want to rehash the entire content here a second time :P)

My current focus is to complete work on DoN’s Menus, HUD, SFX and BGM. The aim is to take all the content available in the game now and package it neatly into a playable build.

For now though, enjoy this video of DoN’s agile Jumping spiders absolutely trouncing prey in style!


DoN Status Update for January 2016

 

I wrote a comprehensive post in DoN’s WIP thread on the Unreal Engine forums so that I’d add rehash that content here too while I was at it. Having all your content in one place is ideal but sometimes it can pay to add that extra bit of effort in developer forums especially for a technically complex game like DoN where there’s features that are sure to interest other game developers as well.

 

I’m also preparing a video for DoN’s first comprehensive gameplay demo! Not some fancy cinematic eye-candy backed by another astute selection of Vivaldi’s fabulous music, but the actual game with detailed commentary for many features I’ve never shown to date! (and there’s many of those for sure).

 

As Above, So Below!

As Above, So Below!

For now though, here are some massive DoN updates from last month:

 

1) DoN’s Voxel/3D AI Navigation for Unreal (as free plugin soon!)

Nearly all my time has been consumed by work on DoN’s voxel-esque 3D AI navigation. The good news is that by redesigning the system from ground up I’ve managed to pull off tremendous performance gains all across the board – generating 3D voxels is now faster (meaning players need to wait less for the game to load), high collision accuracy that was once considered unfeasible is now blazingly fast – to the extent that DoN’s butterflies now exclusively rely on this 3D / Flying AI package to travel from flower to flower amid some pretty dense foliage! The level of voxel accuracy needed for this was beyond reach with some of the previous techniques that I discussed last year on DoN’s youtube channel (or indeed, even the recent approach the game was using in December 2015).

 

It gets even better -fully dynamic obstacles are now supported! Blooming flowers accurately tag the chunks of voxels around them as unnavigable and even a blade of grass growing on the ground now can dynamically update the navigation voxels so that DoN’s tiny creatures don’t bump into these grassy walls! I’m also working on creating a separate plugin for this system; this involves decoupling my own game’s classes from the system (a fair chunk of refactoring) and learning about how Unreal’s plugin system so I can bundle it up into a nice tidy package. Why, you ask? I plan to release this plugin for free soon!

 

Here are some screenshots of dynamic collision (red voxels amid green) “blooming” around flowers including a pic I didn’t post on the Unreal forums (some fresh content for those visiting DoN’s website eh :))

2) Species Deisgner!

Simultaneously, I also worked on developing a scalable architecture for DoN’s Species Designer; this design is capable of rapidly onboarding new species of plants/animals/etc… not just species designed by the developer (i.e. me), but also (and especially) species designed by players themselves!

 

I had to throw away and rewrite vast amounts of existing code as usual. It’s quite a leap going from “this creature is a butterfly, all butterflies have x, y, z traits” to “this is a winged creature designed by the player that has traits x, y, z and therefore may interact with a hypothetical Species “S” with traits a, b, c under specific constraints defined as k, l, m, etc). It was a difficult a process to be sure, throwing away code that I’d painstakingly built over several months and trying to fit things back in – like pieces of a jigsaw puzzle, into this new, generic, species designer friendly framework. Painful, but absolutely worth it. Having strong, robust architecture as the backbone of your game (or indeed, software) provides an immense sense of relief and confidence, knowing that when the time is right, this thing can grow unimpeded into a large scale ecological simulation. Obviously the technical demands for a complex ecological simulation are pretty unforgiving (AI navigation and behavior across a huge variety of terrains, myriad species with highly bespoke locomotion and behavior, huge performance concerns for eusocial insect colonies, etc, etc) so any amount of time spent in perfecting the core classes and frameworks early on in the game is time well spent in my opinion.

 

Back to the Species Designer – this thing allows an unprecedented degree of customization for DoN by enabling players to design new species for the game, eventually controlling morphology of any species (the most difficult part), behavioral traits (almost there) and complex lifecycle events with intuitive event dependency chains that players themselves can add (should they desire to do so). The game itself will be released with a decent selection of developer created species, not to fear. Initial versions will probably have only a limited selection of insects, plants and hopefully some reptiles and amphibians. Birds are probably do-able, mammals are admittedly a distant dream. I’d rather have a small selection of species whose lifecycles (and lives) are well portrayed than a motley collection of creatures. If I’m able to develop a rich Morphology Editor for DoN’s Species Designer maybe even players can help with the process but that is a stupendously difficult technical exercise – several orders of magnitude more challenging than even DoN’s Voxel Navigation when animation solutions for custom morphology are taken into account.
Morphology aside, a Species Designer UI for designing roles, traits, lifecycles, etc hasn’t been developed yet either. I do have a developer version of it backed by Unreal’s native editor widgets but the actual player interface (backed by Unreal’s UMG or even raw Slate UI technology) is a crazy amount of work to do. I’m optimistic though, as architecture level support is there and data structures for the persistence layer are more or less locked in. And that’s what’s important for now.

 

Here’s a simple ASCII diagram – a brain dump of my thought process around modeling a generic species defined by player driven roles and constraints. Read the following sections more a more detailed take on how this actually works.

 

Species Roles System

 

3) Writing AI for a creature you don’t know at compile-time

The creators of Spore wrote an interesting paper entitled How to animate a character you’ve never seen before. I haven’t decided if I want to tackle that problem yet, but I do face a similar quandary myself – How do you write AI for a character designed by the player after the game is released?

 

To solve this I came up with a “Species planner” system. Each species (plant or animal) has a “Roles Plan”, “Lifecycle Plan” and “Locomotion Plan”. “Actionable roles” operate in a dual subject v/s doer modality. Players will assign appropriate roles to each species and enjoy full control through exposed metadata. A role itself is implemented fully in code.

 

Here’s a screenshot straight from my forum post with some practical examples of how species roles would work:

 

Roles Table

 

There’s more to it obviously, but this post is already getting long so just let me know if there’s interest and I’ll do a video on it when the system is ready for show time.

 

4) Camouflage System

A basic camouflage system is now ready! Both players and AI are governed by “Visual Trails” which react to the kind of surface a creature is sitting on, the speed at which it moves, etc. Bonus points for creatures with naturally disruptive patterns or pre-camouflaged morphological features (eg: Lichen Huntsman Spiders, Spiny Leaf Insects/etc).

 

Camouflaged Butterflies

 

Can you spot the butterflies in this pic? Jumping Spiders have superb vision though, so they sure can!

 

5) IKinema IK for foot, biting, etc

I purchased an IKinema Indie license recently and have started using it for Foot IK, biting etc. I’m going to do a complete video on it when I get some spare time (lol ) but here’s a screenshot for now. Foot IK for our eight-legged Jumping Spider was setup very quickly using their Foot Placement node. This is what ensures that the feet are grounded to an adjoining surface (even the underside of a petal) as opposed to having feet hanging in mid-air or poking through the upper side of the petal breaking immersion completely (this is what was happening before I setup IK).
