Putting the product youre working to ship aside, the world youre building is absolutely beautiful. I can't wait to try my hand at building me own engine. So inspiring.

[@vickylance]

Hey, man :D Awesome to find you here. I can't wait to see your video building your own game engine :D

[@ccstudios2960]

Nice can’t wait for the release! Also you should make some tutorials on how to make a game engine, I think it would be interesting to see how it’s done! Love your work and can’t wait to see how it turns out!

[@_Nerdiful_]

Check out The Cherno's channel. He's been doing a series on writing a game engine from the ground up for months now.

[@forgilageord]

Thank you, KZbin algorithm, for showing me this amazing looking game. Never heard of this before, but now I'm looking forward to its release!

[@z-beeblebrox]

Starting from rivers is brilliant! This is one of the few procedural terrain generators I've seen that generate rivers correctly because of it (well...as close to correct as reasonable!) I notice too, because of the way it uses the rivers to calculate terrain height, that you have lots of areas with very shallow banks (which is uncommon in games but very common irl), and that makes me wonder what it would look like if you added a very slight wave-ish motion to the water's actual height. I think you'd get some really interesting looking marsh-like areas where the banks are especially shallow. Plus, if that works, then you could introduce flooding! :D (or maybe not that sounds kind of brutal if the game can just wash away all your progress)

[@benrex7775]

I love the idea of marshes and waves.

[@surrealsupercell7217]

Natural disasters would actually be kinda cool...

This guy is making something really special. I don't even care when it releases. Just watching this design process unfold is super fascinating. I wish other games like Ancient Cities and Ostriv would do videos like these.

[@DeliusVDB]

Can't wait to play this when it's released. It look extremely good.

[@SizzlingSquiggle]

It's so cool to see you working from a distant view of the world... because you forget how small you are in it and how beautiful the world is when you step inside it!

[@criminallyinsaneskel]

I'm excited to setup a tribe on a river with those stunning views and send a boat down the river or explore that nearby mountain! I can't wait to see what there will be to find! Ancient treasure, other tribes, animals, who knows what else! I am also loving these videos, fascinating technical overview!

[@surrealsupercell7217]

The sense of vastness on being a real planet is simply incredible... Especially with the terrain detail and realism.

[@matyastomoga9944]

One of my favourite part of Rimworld was that you could travel, if you can make that good in your game, that would make the game a lot better! And you could also make secrets on the map, like obelisks and there could be a mystery to solve like in Surviving Mars. Keep up the good work!

[@gderu6109]

[@jeanjacquesstrydom]

From all the dev log videos I've seen, the world in Sapiens is by far the coolest terrain generation

[@houstonhampton2418]

Congratulations on the baby. I don’t have a pc but I’m very interested in this project. Keep up the great work

[@MrHeliMan]

I love your work. Each update seems to bring great features. The rivers look so realistic from the globe view too. I wish you keep adding features and make the planet more memorable and less flat. More biomes, caves, waterfalls, very steep mountains and such... It could end up looking like the Middle-earth :D

[@maxsmith8196]

This game honestly looks like my dream, I would to have a world generator like that alone. But to actually be able to play in the world is mind blowing to me, the feeling of the game is very important to me, and so far you’ve just nailed it! You take so many things that similar games struggle with, and find a way to solve the problem, instead of just doing some kind of patchwork of easy solutions. Can’t wait to where this goes!

[@UnintendedSheep]

That new tab to create a new world is amazing! I cant wait to mess around in this game. It looks like so much fun! Also grats on the baby!

[@gblawrence034]

Just recently stumbled across your channel. Started watching your Sapiens devblog series, which is really interesting by the way - I found it fascinating to see the development and creation of an idea and the gameplay steadily progressing. The game looks stunning and I will definitely look at buying it when it releases. Then I looked back at your earliest videos and realised you’re the creator behind some of my favourite mobile games as a kid! I used to play the chopper games for hours on end. Thank you for being here Dave and thank you for logging the journey of your new game. I will be subscribing and following your game from now on. Props to you!!

[@jesswasher7552]

Congratz on the baby!! And about the game i just want to say its looking great so far, and i really feel like you absolutely nailed the atmosphere with the couple songs you have that play.

[@ryann7760]

requesting jungle/dense forest. (ancient temples/structures from a lost civilization would be cool aswell) :) loving the updates!

[@sondrehyland3818]

I realy like the idea of building up a civilization, so adding ancient temples would take away from this mindset. However I am also intrigued by your idea. Adding an option for post apocalyptic world, like the surface in "The Time Machine" or that type of scenario, would be quite mysterious and thrilling!

[@ZeroRelevance]

Ryan Neuman You should copy this to the suggestions section in the discord server. He has a higher chance of reading it there than here

[@thomkok12]

Or be able to make structures like that would be awesome too.

[@ajmentel2453]

@@sondrehyland3818 I agree with you, but what is funny is that society as we know it currently doesn't recognize that there have been large societies before us that fell due to environmental changes that sent us back to the Stone Age and that our society is the result of our ancestors picking up the pieces. If you're intrigued, check out Joe Rogan's podcasts with Graham Hancock. I bring this up because I feel as if this game will try to incorporate some hints of mystery and things unexplained into it, like Minecraft or Terraria. But, Sapiens seems more grounded than those two titles, so adding mysterious ruins and ancient decrepit temples is definitely the way to go.

[@rijugas]

@@ajmentel2453That sounds ridiculously stupid...

[@ncoll36]

This game has such a beautiful aesthetic to it, and enabling biomes again adds so much more to it. I can't wait to see what other sort of content you add to this base engine along the way. I'm glad you brought up about how you plan to start the game and how you'd normally interact with it, because I've always wondered about how you speed around and things popping in and out of render. The way you plan to do it seems pretty solid to me.

[@DandolfiGames]

Looks great! Gotta love that globe view with the sliders! Amazing work, keep IT up! Looking forward to future updates

[@MaxEthoWatch]

I understand that having trees be visible from long distances is a performance issue, but if there were some way to make forested mountain-flanks appear darker green and mottled, that would be awesome; at the moment they look tragically barren. Love the work, been following since Ambience!

[@RialuCaos]

Maybe he could make the level of detail change the 3D trees into 2D billboard sprites with just images of trees at a distance? I'm not sure how it'd look but it might be an improvement from the complete disappearance of trees.

[@kiawildberger]

@@RialuCaos ive seen something like that done somewhere, and it was either bob ross or some rendering engine iirc it looked really good and wasnt bad performance-wise

[@spdhome]

Love the procedural generation! It's looking really nice. To add a bit of diversity to the rivers you might consider adding spring locations in certain biomes. A spring could generate pretty much anywhere and create a river or stream that would work it's way down to the lowest point. If it generated at a low point it would create a pond or lake, not sure if that fits in with your waterway system of travel though.

[@bradyunderwood8171]

LuaJIT is what he mentioned. JIT stands for "Just In Time", and is used to refer to compiling an interpreted language (like Lua) as you use the functions, so next time they're used, they don't have to be reinterpreted.

@@Gidaio lol, maybe I should have gone back to listen. But still, I am keen to find out more about it.

The terrain needs to be much more granular, you know, like small hills and the like. Right now the entire world feels like a desert with different colors; You could think about little cliffs, some small hills, more variation in terms of vegetation (like different colored grass, that would already add so much!) You're a huge inspiration, every time I watch these videos I get a boost of inspiration to just go and create stuff!

Just imagine how you can take this game. An I'm sure you can even Change it and release several games with the same base An idle viewing experience Or a strategy game.

[@benrex7775]

I like this change. The worlds are getting more interesting with every Devlog. And if I look at your forum I can see that I'm not the only one who likes a realistic landscape. And a good waterflow is the backbone of a realistic world. Is there a way to copy a world so that several people can play on their own version of the same world? Something like an overall seed, not just the seed for the random number generator. And congrats to your baby. Why do you have 4 children? That's quite a lot nowadays. Quite a few families around me have semi-big families as well and I plan to have that as well at some point. But if you look at national averages it's kind of rare.

Good luck with the next few weeks! On the rivers, minute physics has a great video on why rivers curve. I think the randomness could use a pass of river curves over the top.

[@JBzucc]

You could make it so in some areas along rivers instead of sand its more rocky and the river bed and banks are pebbles Also I'm guessing you've already planning this but a more Savanah type biome with dry vegetation so its not going from a forest to dry desert all of a sudden

[@ai-spacedestructor]

looks interesting, adding it to wishlist and coing to follow the development to see how it continues.

[@DreapsterAtRoblox]

Also a pattern I notice which makes it looks a little less organic and not like real planetary terrain is that there is no continental shift a lot more than often pieces don't connect from the continent its drifting from they just look like random cookie cutter spots cut out rather than pieces broken off from older land masses I don't know if that's intentional but it's easier to sense predictable generation even if it does look nice

This game looks so amazing man I’m so hyped

[@cjshakes]

Hey quick question! Although its hard to explain.. So are you going to have some sort of "scaling up management" that occurs as your civilization progresses? A much easier question! Will there be hostile npc villages? Or maybe actual diplomacy with some being hotheaded and others more nuetral or friendly? You can ignore the rest below if I'm totally off. Just trying to explain the possibilities. I hope to see your response! (or you can write these down for your next FAQ video!) What comes to my mind is how Spore did it. What I imagine is you begin with individual people and their needs as well as building individual houses, wall by wall. Then once you reach some milestone you place prebuilt houses or workshops (whether designed by the player or yourself). There'd be some mechanic of clicking and dragging for roads and farms. Also, you would no longer care about individual peoples hunger but whether there is enough food, beds, etc. Maybe a happiness boost for private living or improved houses? I imagine this level of management could be successfully scaled up the whole way to space-age stuff.

[@TheStupidGuyWithBlip]

I think you should start rivers with a random width value, which decides how many times it can split off. Each time it does, the branches split a random amount of the width among them.

Some ideas: Add saplings so that you can replant trees Make the grass regrow over dirt when there isn't an object on top of it so that it looks natural when you place terrain. Seasons and weather. Imagine some thunder for example which would make the people hide inside. Would be really cool!

[@mikaxms]

Are the rivers dynamic? In real life the rivers slowly move/change by pickup and dropping sediment. Also, do plants drop seeds resulting in new plants?

[@nn6404]

having more sheer cliffs and physically intraversable terrain would be amazing. Like I'm imagining mesas with huge gorges for rivers. Or tall pillar mountains like you'd get in China. You're getting somewhere with these river valleys being the starting points for the tribes. I think that a lot of this game could derive from how you interact with the landscape. Especially given the way that you've built the physics engine.

Kinda tangentially related, but I've noticed that there is this sort of aesthetic that your game has that it seems like Australians like a lot. The fonts and way you set up the ui and icons especially show this off a lot, but your choice of colors and the specific way you simplified things and made them cartoony is something I've only seen Australian things do. Where does that come from? Do you know? Or is is just this thing that looks good to you and seems obvious?

[@seagullseb9209]

I remember seeing your earlier devlogs and the game has definitely became amazingly brilliant in its current state. I'm also wondering what kind of progression are you planning on adding to Sapiens? Is it going to be all the way to high tier technology and stuff like space exploration and such or is it going to be more primitive/medieval kind of technology advancement? Either way cant wait to play the game. (also congratulations on the baby)

[@rachard]

KZbin Reccomended this to me *Now im hyped for the game*

[@hurktang]

I don't know if you want this information or not, but rivers are more sinuous in steep terrain and harder soil. And type of ground will also play a massive role in biomes. At this point you might go all the way with the idea of generating the mineral type of the terrain.

[@matthewgrotke1442]

Fabulous! Very impressive deciding to start with rivers. As someone who has done significant mod programming with the Source engine, I totally support your decision to use small modular C binaries as a plugin system. It's really the best option for performance. For security reasons, however, you do have to be cautious when players start posting pre-compiled mods. I know it's more work for you, but perhaps you could include a built-in compiler with the game, and force users to write mods in plain text only. Your built-in compiler would then take the plain source file and insert a unique key (a const or something based on the hash of the source) and your game would check for that key to ensure the mod was locally-compiled. That way, at least people would be able to review the mods they download.

[@matthewgrotke1442]

The nicest plugin system for modders is an event based system, where your game defines a bunch of events and mods have the opportunity to subscribe to events. It could be as simple as you have a bunch of folders. Like a folder called Player_Jump would correspond to the Player_Jump event and your game would run every mod in that folder whenever the player jumped. You could simply name the mods "0.mod", "1.mods", 2.mod", etc or whatever to determine the order of execution, although a more robust mechanism would involve some sort of mod registration screen where the user could move their run order up/down or temporarily disable them from within the game. For security reasons the mod files should only be plain text. Each start of the game, an integrated compiler will hash them, add security features, and dump their blobs into a single binary. If you compile the mods yourself, you can do some simple checks on their dependencies to ensure they aren't accessing resources they should be. You can check that all their variables are in the local scope (defined and used only within functions). Since the mods would run and immediately exit whenever called, they would have no ability to store persistent data across the life of the game. You could consider providing a game API that allows them to store and retrieve variables.
