Dev Progress (Dec 4-24): New items (including Gnome Caps & ingredients), Lockpicking, AI GOAP, Hurt-frame improvement, Audio (music ducking), and more...

Posted by on

Season's greetings! Unfortunately, we won’t be releasing the first public demo this year. We are getting closer and hopefully it won’t be too long into the next year before we get there. Nevertheless, here’s some of what we’ve accomplished this month:

tar_holidaygreeting(Interesting food choices)


There are now Gnome Caps! Which come in a variety of colors, not just green and red. There are also two variations, one with and one without the furry ball.


LOCKPICKING

You can now attempt to pick locks on doors or containers if you possess a lockpick. To lockpick, equip a lockpick and simply hold the ‘attack button’ while looking at the locked object. The radial meter will fill on your cursor and once full you will either succeed (picking the lock) or fail (breaking your pick).

Lockpicking experience points will be rewarded whether you succeed or not, however failing will reward less. Dexterity increases the speed the radial meter fills but your Lockpick skill determines your chances of succeeding. So you can be a very slow but skilled picker, or vice versa.


PICKING

New consumables: blueberries, strawberries, and acorns. As well as the new strawberry and blueberry plants. Oak trees, which have already been present for a while, will now drop acorns.

We wanted to get in some more ingredients that can be used for alchemy and we plan to make a few more before the public demo.


GOAP

NPCs are now using a system referred to as Goal-Oriented Action Planning (GOAP). As opposed to a State Machine, where transitions must be clearly defined between all states, GOAP allows more flexibility. In GOAP, you define actions and conditions for them that the planner uses to find a most cost-effective path towards the desired goal. Since, eventually, we want to have many variations in AI behaviors, this system makes more sense. However, it takes quite a bit longer to setup.

(Guess I shouldn’t have dropped that Quarterstaff over there…)


Jon has setup some goals that NPCs will attempt to fulfill such as Arming and healing themselves. If there’s a nearby weapon, and they are unarmed, they will go grab one as shown above. Also, they will consume healing items when their health is low. In addition, NPCs can actually use ranged weapons now, although not very effectively in many cases – it’s still a WIP. Anyway, It’s coming along and definitely makes interaction with NPCs more enjoyable.

For anyone interested in how GOAP works, here are some of the sources Jon has been using to develop the system in The Arcane Relics™:


NEW SHELVES & SCROLLS

We thought it was a bit cheesy having only primitive cubes & spheres for acquiring abilities in the public demo, so we made some quick scrolls to solve this. And now they appear on these diagonal shelves.


HURT FRAME IMPROVEMENT


tar_thinhurtframe(Looks pretty good for a 32×32 texture)


We got a lot of feedback about how the previous hurt frame was obstructive, which came way into the center view. We came to find it annoying ourselves, especially when you had low health – as the opacity increases and remains – but we still wanted to keep the additional feedback for when damaged or being close to death. Therefore, we changed it to the simple smaller outer frame as shown above and saved some texture memory in the process.


AUDIO: MUSIC DUCKING

The audio overhaul continues! There’s now layered music tracks: basic, weather (rain), interrupt (battle), & musical accent. Thus:

  • Musical accents (such as leveling up) cause all other music tracks to duck and to fade back in, after they have finished.
  • Rain overrides the basic music. That cheery town music didn’t seem to set the right mood when it rained.
  • The different layers can change, even if they’re not playing. This fixes some bugs in resuming wrong music clips (thus returning the track to rain instead of the town tune after a battle).

DEFERRED RENDERING

We mentioned (in our last post here) that we were planning to try out Forward rendering for a while. Well, after weighing the pros and cons, we found that we are sticking with Deferred rendering. We are using many dynamic, non-baked, lights, which Deferred handles much better than Forward, and think it’s vital to the design and look of the game. We also have found some workarounds and made some compromises for other issues we were having with Deferred rendering, like the outline around objects intersecting a player’s cursor.

Outlines around objects intersecting a player’s cursor will now be visible to all players. Previously, what highlighted for you would not be visible to other players. Alas, the system Jon was using created new materials and memory leaks, so good riddance. In Forward rendering, he was able to hide the outline per view with the new system but can’t seem to get that working in Deferred. So we have decided to have outlines visible to all players! Have a look:

(It’s kinda nice to see what other players are looking at.)


We’ve set the normal cursor and the object outline to tint to the player’s color, which is based on their ID (e.g. Player 1, 2, etc.) to hopefully make it clearer whether it’s your highlight or not.

If you’re interested in the differences between the two rendering paths a quick search of “Forward vs. Deferred rendering” would give you many results, but here are a couple of links anyway:

MISC IMPROVEMENTS & BUG FIXES

  • Scene intro text (eg. Water Cave) will now tint red if the scene is considered ‘dangerous,’ where all players being incapacitated will restart the scene.
  • Optimizations: setting up Level of Detail (LOD) meshes on equipment & various objects in game.
  • You can no longer sprint push while crouching.
  • Falling out of the map in the Grand Arena, hitting failsafe trigger, should now correctly reset the Area you are in to the underworks (no invisible walls).
  • Rain should now persist between scenes.
  • Weather changing console commands now happen immediately. Rain begins and stops almost instantly!
  • Combatant NPCs now cleanup after an arena match.
  • Added a console command, ‘condition damage’, which makes items flash a solid red when taking condition damage.
  • Adjusted Water Cave ambient light to make the dark areas more blue.

Happy holidays everyone!
