Game tips, fixes, Water Well monuments, viewmodel clothing, and more.

25 January 2018

One of the last things on the roadmap for leaving early access was a series of game tips that would appear contextually for new players to help them learn the game. I spent this week finishing these. We've added about 20, which should help players learn how to do things like drink from lakes and rivers, use bows, and play the mining minigames. In case these are popping up for you veteran players... don't worry, just do the action a few times and they will eventually stop appearing. Hopefully new players will have an easier time getting into the swing of things. Next week I plan to implement a 10 step tutorial that guides players through crafting their first tool, to building their first base, and visiting their first radtown.

Some tips didn't fit into the game in a contextual way, so I've added some text to the top left of the loading screen, which will cycle through helpful hints while you're waiting to join a server. These range from reminding people that they can wash off radiation in water, to being able to melt cans for metal fragments in a campfire. All in all there are about 25 loading screen hints that will cycle randomly. Please don't be shy to suggest new hints for us, as implementing them is very easy.

I think SMGs may have been a little too expensive in requiring two Springs each, so I've removed one Spring and 5HQM from the Thompson and Custom SMG costs. Maybe we'll see them being used a bit more? Or maybe I'll actually have to nerf the AK47 even more?

I always thought it kinda sucked that you had to find a blueprint to get a decent melee weapon. I've made the Machete a default blueprint requiring a Tier 1 Workbench. I may remove the workbench requirement next week, but let us see how this plays out.

Planters once again show their saturation value via a darkening of the soil. This was disabled for some time due to performance considerations but has since been fixed. Note that there is a small bug where the wood gets darker as well, which will be fixed next patch.

Remember how annoying it was to have to use 300 frickin’ Wood to craft a Sheet Metal Door? What about 100 Wood for a Sleeping Bag? Well, don't worry about it anymore because those costs have been removed from both of these items.

Paper was a totally useless hoop players had to jump through. I've removed it from the game so the Note and Building Plan can be crafted directly from Wood instead.

Now that the viewmodels are using a single consistent rig, I've gone back to the viewmodel clothing I prototyped a couple of months ago.

It's something that's been requested pretty frequently, but it takes a fair bit of effort to get something that looks acceptable, and even then we'll have to make some concessions in the detail we're able to display. The items were all designed with the criteria of being seen on another player, showing them on the viewmodel is displaying them many, many times larger than the polycount and texture resolution was intended for (particularly visible on the Burlap Shirt, bottom right) and unfortunately upping that resolution isn't a viable option due existing skins being authored at a specific resolution.

Despite these issues, it's pretty awesome to pull out a gun and see what you're wearing after all these years of staring at your naked hands.

I've done a pass of most of the attire items that will display on the viewmodel, although I think I'll go back and add just a little more geometry to try and eliminate some of the artifacting. I should be able to get them finished off next week, provided there are no major issues, ready to hand off to a programmer to get them implemented.

I added two more variations of the Water Wells I introduced last week. Here's some pictures:

A side effect of the restricted movement for players on Junkyard meant that the helicopter loot would sometimes get stuck floating in the air on top of invisible volumes. That part is fixed. However, if you are looking to farm the patrol helicopters, look for a different site as the crashed choppa could still fall within restricted zone at Junkyard. Be smart, take it to your pretty base instead.

While debugging the memory leak, I came across a number of areas that could be optimized. The biggest one of those was an overhead of 5ms and significant GC allocations whenever taking damage over time from things like bleeding, cold, heat, starvation or dehydration. This was a pretty significant hit as the damage was applied multiple times per second, so it quickly added up to losing multiple frames every second.

Another one was a 6ms hit every second from refreshing our reflection probe, even though we barely render anything in the probe. I reconfigured some parameters and reduced the impact to approximately 1ms - still not ideal but it'll have to do until Unity gives us better ways to deal with this.

Alistair and I are in the process of debugging an elusive memory leak. It's one of those things that occur at seemingly random times and can take hours to reproduce. We're trying to narrow it down by systematically eliminating potential causes, but so far we haven't had much luck as neither Unity nor Mono even show the memory that appears to have leaked. I still wanted to mention it so you know we're working on it.

I spent the better part of two days debugging our infamous "crash on exit" issue. It was rather difficult to track down, since most of us weren't even able to reproduce the issue, and even when it happened the game didn't give us any stack trace in the log, which made crash reports from players rather useless. What it came down to was that we were shutting down EAC before disconnecting from the server. Duh. Say goodbye to this:

If you own a skin for a Bandana, Boonie Hat, or Cap, the item was supposed to become unlocked for you to craft. Unfortunately we had a bug in the system where this only worked if you owned one of the original skins for these items, which was bundled in the game. Because of this it was very difficult to pinpoint the issue as only some people were affected. This is now resolved and owning a single skin for any of these items will allow you to craft it in game on any server. Sorry about that.

The new Douglas Firs and Pine trees are now finished and I've been looking at the performance and the technical side of things. I have done LODs for all of them and have managed to create smooth LOD transitions without noticeable pop-in. I've discussed implementing a custom imposter system that will allow us to render billboards without creating too much performance overhead with Diogo. While there's nothing glamorous to show this week, all this work was essential in helping us figure a way forward, while keeping everything clean and streamlined. With this new imposter system we're hoping to achieve a higher density of trees and bushes and we hope to keep the rendered even at very long distances. I will keep you all updated on all this in the coming weeks.

I've customized the mip-maps for all new trees, too. Unity has a setting that allows for preserving alpha coverage on smaller mip maps and, as a result, the trees now look very full even from far away.

I've continued with the remaining admire animations. The flare and flashlight were new additions, so they needed setting up in Unity as well. I hope to be done on the updates by the end of this week. After that I'll be doing a quick review of them all in context, just to check pacing matches between weapons, double checking clipping issues, making tweaks, etc.

As we navigate towards leaving early access, aside from a few bugs, I've been generally focused on graphics related polishing work. Namely performance and memory overhead. This week I eliminated a few memory allocations in both hair and culling code, as well as runtime optimization for the latter.

I'll keep polishing as much as I can until we leave EA, postponing any new features for later.

I was mostly focused on finishing up the third/first person sound consistency stuff I've been working on this week, and I think it's all done now! I finished up all the hand-held water containers (Bucket, Bota Bag, etc) including making first-person deploy sounds for a couple of them. I did third-person sounds for the Medical Syringe and did a little polish pass over the rest of the syringe sounds. I also made a new set of sounds for the Flare (first and third-person), and made third-person deploy sounds for the building planner.

I did a few other little audio things this week too. The survey charge has a burning fuse sound and nicer deploy sounds now. I adjusted volume of some of our ambient sounds, and I lowered the global maximum voice count on gunshots to alleviate some performance issues that'd crop up if an admin spawns a bunch of scientists and they all shoot at once.

A lot of changes has happened to the Scientists this week. They will charge less, hug cover more and sidestep in/out from it. They will know the difference between advancing, flanking and retreating to cover, and when they retreat they will turn and sprint. They will also know when their cover has been compromized. They'll stop to shoot, rather than run-and-gun with perfect aim. Steps have been taken to prevent their wallhacks, but more testing is required to confirm its been fixed. There is now also a slight delay from when the Scientists spot you to when they start to shoot. Since their behaviour saw so much change this week, we need to test them for at least another week before they are ready for prime time. As with last week, they are disabled by default, but can be enabled by server owners.
