This smaller update adds hunting and wild animals that can be hunted for meat.

[h2]Wildlife[/h2]

I added several wild animals -- foxes, boars, wolves and deer.



These wander around, graze and generally hang out in the forests. I think they add some nice livelihood to otherwise extremely static forests.

[h2]Hunting[/h2]

I added a Hunting technology unlocked before the Herding technology. The Smokehouse will now also unlock with the Hunting tech.



I added a new building - Hunter's Lodge. You can adjust its operating range to cover the nearby animal location. You can also toggle which animals get hunted:



The workers will then run out to any wild animals, shoot them and then harvest them for meat. Meat can be taken to smokehouses same as from the butcher.

Smokehouses will now require Firewood:



This makes early high-quality meat food production more balanced.

I also renamed Pork to Meat and Ham to Roast since multiple animals now "drop" meat and it would be slightly confusing. I might eventually differentiate between the different types of meat, but I don't want to add more items to the market and houses at this time. This is also the reason why animals only drop meat for now and not other stuff like leather or pelts or something.

[h2]Habitats[/h2]

Something to consider is where I would spawn the wild animals. As simple as that sounds, it quickly becomes a rabbit hole (har har) of design questions and decisions.

A naive approach would be to just spawn animals randomly in the forests. I would add some rules to not spawn too many or to not spawn "incompatible" animals together or to choose "nicer" less-populated locations to spawn. I can even simulate some rudimentary population growth. The player would just place hunters randomly around forests.

But there is a major usability problem with all of this. How do I explain to the player how many animals there are in any particular place? And whether they are breeding or spawning or anything else? You can may be individually track them, but this is rather silly:



And secondly, if the player was to hunt out all animals, then there is no guarantee that more will ever spawn right there and the production rate would be inconsistent at best. As a player, I can see how I might completely avoid hunting, especially if I didn't know the rules of animal spawning.

I can add further rules that prevent animals from disappearing and spawn animals for hunters. But now I'm 3 layers deep into spawning rules and this just doesn't feel right. It doesn't fit the sort of structured approach to resource management that I want to have.

So I decided that animals will instead spawn in species-specific habitats, which will have an in-world indicator:



You can mouseover the indicator for all the info in the tooltip:



I think this makes it instantly clear that animals are a "resource" in this location and that it can be "harvested". This becomes a clear source of a renewable resource chain. This is something you can plan for from the start of a new game.

There are some rules to the habitats (which are similar to what individual animals would have had without habitats). They will only spawn in forested areas on around grassy tiles. They won't spawn near buildings or roads. They will decay if the forest is cut down or things are built nearby. Animals will only spawn in habitats. These factor contribute to the habitat's "quality score".

The tooltip also explains when things aren't "working", mainly when new animals won't spawn:



[h2]Game warden[/h2]

Going with habitat quality concept further, I also added Conservation tech and a Game Warden's Lodge building. The warden will tend a nearby animal habitat, improve its quality (and thus spawn rate) and prevent it from decaying even under poor conditions. This is reflected in the habitat's tooltip:



This isn't a big or important feature; I just think it's kind of cool and I haven't really seen it done in other games. It's relatively easy for me to add, yet provides an extra level of depth.

[h2]Parameters galore[/h2]

The habitat feature happens to need a lot of parameters and I think it's a good opportunity to provide some technical insight into these:



Since I am dealing with randomness and procedural generation, everything that can go wrong will go wrong. Every time I add a parameter, I am essentially trying to extract order from randomness and prevent things going wrong. (For example, I would not want to spawn a habitat right next to another one. But this is a perfectly valid random result unless I stop it. Hence, I need a parameter that says how many tiles must be between habitats. In other words, I reduce the number of garbage results from randomness.)



I can change these values on the fly as the game runs. I can also restart/regenerate the world quickly while running to preview changes. Most of the time I start with a few parameters that I expect I would need and gradually add more as I find various edge cases and "problems".

For example, here's me debugging the validity of spawning a new habitat in different locations:



Some of these never get modified unless I make drastic changes. These values may as well have been written directly in code, but having them external makes initial testing much faster. Others I would tweak continuously and those parameters determine balance and gameplay. Of those, some are "public" and these are values you see in the game, in tooltips and such.

Of course, it's not like every parameter belongs to an exact "group". It's more like a way of converting design into implementation. I know I want to show some values to the player. I know I will need other constants to determine high-level decision. I know I will need to cover edge cases. Etc.

A final note is that every parameter adds maintenance. To be accurate, each parameter represents underlying code, which adds maintenance. Having parameters displayed like this together gives me a good estimate of complexity. When I see the parameter list growing, I know that I am increasing the feature's complexity and may be that's not always a good thing.

[h2]Future plans[/h2]

As before, I intend to be making smaller more frequent updates. I don't want to do heavy programming or involved design during the Holidays (especially after last patch's backend work), so I will probably work on some graphics and informational stuff. I think the in-game info codex is a likely addition.
