Sept 6th - Patch Notes 0.7.19

Hello all,

We’re moving our experimental branch to default today. 0.6.19 will become 0.7.19. The update below will go over what we’ve been up to. Along with what has changed in 0.7 and what to expect in 0.8.

This is a big update for the team. We’ve said from the start that Survive the Nights would be as optimized as possible. We’ve kept optimization in mind while developing. We’ve also learned a lot since we started development. We’ve done our best to maintain a standard when it comes to keeping things optimized, however as always, things can slip. It’s not just a loss of attention, everyday the team learns something new. 0.7 focuses greatly on optimizations but it’s not only optimizing we’ve been working on. Quite a bit more has gone into the project backend wise and will require a great deal of testing. You’ll find our current changelog below, it’s a great way to hunt for bugs. As always please leave any issues on our tracker so we can get them fixed!

We’ve also spent a great deal of time focusing on quality of life improvements in game. From improved player spawns to containers showing a inventory preview in our small UI box. Below you’ll find a list of fixes, improvements and additions that have been made for 0.7. Below that, you’ll find some information about 0.8 and our plans for the future.

General Fixes and Improvements/Additions

  • Fix for game starting in windowed mode.

  • Fix for hidden servers not working correctly.

  • Reduced overall size on disk for game from approximately 10.5gb to 8.5gb.

  • Fixed broken UV's on low quality water.

  • Dead/Rag doll characters no longer fall through roads.

  • Fixed issue where not all items that should be spawning were being chosen.

  • Enabled v-sync by default which limits frame-rate to 60fps and stops the GPU running at 100% usage unnecessarily.

  • Terrain in distance no longer casts unnecessary shadows.

  • Reduced waters overall GPU overhead.

  • Fixed several materials in the finishing town that didn't have use effects.

  • Fixed missing material on truck docking area in large grocery store.

Engine Upgrade to Unity 2017!

After being in unity 5 for over a year, we felt with this update it was time to upgrade to newer version the engine. This will allow us to take advantage of newer features/optimizations and not fall behind on supported Unity builds. After extensive testing of the newest unity releases, we felt that Unity 2017 LTS (Long Term Support) offered the best upgrade and stability at this time. Listed below are some of the advantages of upgrading the engine.

Shadow Improvements

Culling of shadows casters in 2017 has been optimized. This means there will be less objects casting shadows resulting in better performance. Improved filtering algorithms should also improve the look of the shadows as well.

Scene and Asset Bundle Improvements

The new unity update also includes improvements to the loading times of scenes and asset-bundles. These changes and several other small fixes we've made should help reduce the lag spikes when walking around in the world.

Particle Improvements

New tweaks to the particle system will allow us to create more realistic and optimized effects.

Future Proofing

Staying on newer builds of unity keeps us up to date with the newest features and support.

0.8.x and What's to Come! We're very excited about our next update. The 0.8.x update will introduce our first iteration of window fortifications. The player will be able to attach fortification materials to window frames and door frames. We'll introduce the feature with multiple plank types along with sheet based materials such as plywood and corrugated tin. Below you can see the system in the works.

Ignore the blue highlight, that's backend stuff. The player will simply walk up to a window with the proper tool in hand and if they have the required fortification materials it'll come out and snap to the window.

The player here is switching (ignore textures) through plank types. Weak planks (harvestable via fences and wood piles) vs stronger planks crafted from felled trees. We'll also include sheet materials like tin/plywood.

Just a short example of how boards can be manipulated once snapped to a window frame. This should add quite a good deal of customization adding the ability to totally cover windows or create space for shooting/viewing.

Here's the mechanic a bit further along showcasing the on plank UI. This will let the player know exactly what type of plank they're adding, how strong it is and how many they have. If the player highlights an already placed plank, it will show the player that planks current strength and that they can add nails to improve it.

Aggressive AI, Traps and Trap Damage

Of course now that windows are fortifiable, zombies will have to get through them. Below is a gif of the logic going into making that happen. You'll notice our off navmesh link orbs in the gif, this allows the AI to move through the opening and it's part of our test scene. This is a showcase of the logic. Eventually zombies will come through openings in many ways with the addition of more animations.

​Defensive traps will also be introduced in 0.8.x. With that in mind, work has been going into environmental damage. Below you can see both the player and a zombie taking fire damage. We've also smoothed out placement system, objects (traps included) will now follow the terrains contour on initial placement.

Smoothed object placement snapping to terrain regardless of it's angle.

The logic behind player damage via world objects like fire and traps are now working.

AI taking fire damage. We love the smell of burning zombie in the morning.

New Spawns and Points of Interest We've introduced new a new spawn point system in 0.7.19. We'll be slowly introducing points of interest at these spawns in the next couple of updates. The player should begin spawning near stuff making initial gameplay a bit more exciting.

Orange arrow is one of the spawns. All the green boxes are additional structures or design.

Just off a fresh spawn, small areas like the one above will also have road signs pointing towards the nearest towns.

Small Weekly Devblogs Some of you might have caught some of these screens and gifs in our DEVBLOG. We'll do our best to get smaller updates out every week (unless we're releasing a proper update like this). These updates will serve to provide our supporters with up to date information, showing some of what we've been up to each week.

We're Looking for Help!

As our last update mentioned, we've moved from our tiny closet of an office into a much larger and not so embarrassing space. We actually have the room to expand the team now and we're looking to do just that. If you are or know any programmers/unity developers looking for work in the UK please let us know. We're looking for like minded devs, the project is near and dear to us. The team is very small and being a team player is very important to us. If you'd like to send a CV to please do so :)

As always, thank you very much for the continued support. The project is really starting to shape up and the team is very excited for the future. Feel free to drop into the Discord and talk with us one on one!
