Seismic Shift

A non-exhaustive list of power values from explosives:

We’re making several fishing changes this month to try and shake up the broader fishing meta. Our current issue is that it’s quite trivial to endlessly produce fish from a safe zone, then converting that fish to scrap. It’s not the fastest way to earn scrap but it is pretty reliable.

Our intention with the range of fish available to catch was always that you would work your way up the chain - catch a sardine, use that to catch a trout, use that to catch a shark. By allowing raw fish meat to be used as a bait you could easily gut one fish and catch dozens more fish with that meat, which could then be converted into even more fish.

To break this loop, this month raw fish meat is now only worth 0.5 bait (and can be used in stacks of 3) - whole fish can (and should) be used as bait but you now run the risk of losing that fish when casting out. The idea is to introduce a risk/reward mechanic. Do you cash out with your current trout catch or do you put them on line and go for the sharks? 

To balance out this reduction in bait, we’ve made several other forms of bait more useful. Several bait types can now be “stacked” - if a fish requires 5 bait to be caught and you stack two Worms worth 2.5 each, you can now catch that fish. This behaviour is applied across worms, grubs, berries and small fish, making these baits more viable. We’ve also increased the bait value of human meat (1 -> 3), bear meat (5 -> 10) and wolf meat (5-> 10). The stack amount can be seen next to the bait value when selecting the item in your inventory.

The Survival Fish Trap became a bit neglected after we introduced the Fishing Rod, so this month we’ve adjusted it to make it more relevant. The trap now uses the same underlying fish/bait system as the rod, meaning you can catch different fish in different water sources as well as catch better fish based on the bait provided. The only mechanical difference between these two fish sources is that the trap cannot catch the same fish as it has used as bait and the trap has a 50% chance to lose the bait without catching the fish. 

In hack week this month, I explored ways to reduce our memory usage, an area that is a real priority for us this year. While a lot of my experiments weren’t workable, one did actually end up saving several hundred megabytes of memory for very little cost, so it’s shipping as disabled by default this month.

A renderer in this case is simply a thing that is visible to the player - a crate, a rock, part of a structure, etc. Importantly for performance each renderer has LODs (Level of Detail) - lower quality versions of each renderer that we switch to based on the distance to the players perspective. In Unity each of these LODs typically lives on a child object of a master parent object, so Barrel01 will have a child Barrel01_LOD0, Barrel01_LOD1, etc that we switch to. What I discovered during hack week is that in a proc gen map of 4.5k size, we can have upwards of 1.3 million objects in the world, each of these objects has some overhead (we need to store its position, rotation, what the object does, etc). In a renderers case, for every single renderer we had 3-5 child objects, one for each LOD level.

I realised that in most cases each LOD object was just sharing a duplicate of all the information except for a different model, so I modified the system to detect when this happens and consolidate all needed information into a single object, then delete the child objects. By applying this to every renderer in the world, I was able to delete 385 thousand objects from the world, which had a combined memory saving of 484mb - pretty significant! 

This combination process is run every time the game is launched, we’re currently working on a change to make most of these modifications before we build the game, which should yield further savings next month.

Due to how risky this change is (deleting 385 thousand objects has had some unintended side effects that we’ve now fixed), we’re shipping this new feature off by default, but we’ll monitor it’s usage through the month and likely turn it on by default sometime next month. The convar is graphics.collapseRendererLOD and you’ll need to restart your game after turning it on or off. Let us know how it goes for you!
