Saurian DevLog #9 – “You bred raptors?”

It is DevLog time again! This week we have raptor ontogeny, the science of dinosaur nutrition and a giant turtle concept.

This past week Tom, Bryan and I knuckled down and put together the final stretch of art assets that need to be created for the initial release. Item one on the list of priorities was getting the Dakotaraptor ontogeny done. Despite Henry’s milk related distractions I was able to complete the texture work over the weekend. Much work still left to be done, expect many more updates from me in the following dev logs. I’m a busy busy guy.

Dakotaraptor growth series.

In the past couple weeks our programmers have been working hard on some important-but-not-particularly-devlog-suited progress, so this week will be a short update about one of the few, neat ways that we’ve tried to incorporate paleontological literature directly into our code. While many survival games have a simple “hunger” meter that depletes at some arbitrary rate, we wanted to make our system for dinosaur metabolism more complex, with simulated stomachs and digestion. Andrew Clarke, in his 2013 paper, described an algorithm for a hypothetical metabolic rate of both mesothermic carnivores and herbivores, which, with some correspondence with Clarke himself, I was able to translate into C# for use with our dinosaurs’ digestion system. It’s the type of detail a player will never be able to notice during gameplay, but we pride ourselves on basing our game on scientific literature whenever possible, even when it won’t be obvious to our players. Stay tuned for some more juicy programming tidbits in the coming weeks!

I’m now working on some of the smaller non-dinosaur, non-playable animals. This last week I have been doing concept artwork for the giant softshell turtle, Axestemys. This river turtle had a leathery carapace, with the “rim” being boneless. It’s crazy how large it was too: with a carapace covering well over a square meter of ground, it would be a quite a snack if you manage to get close enough through the mud to catch it. Oh, and I also re-touched Leptoceratops, now with 100% more patagium! If by any chance you have seen RJ tell him we miss him. Come back RJ, I promise I wont hit you again.

    How about make Alamosaurus, it’s a saurpod which would length over 45m or more when they fully grown. Or a saurpod which is even much more bigger ~ ❤❤❤

    • paleosir on December 14, 2016

      Alamosaurus has not been found in Hell Creek, the formation the game is set in.
      And 45m is a pretty big overestimation: a lil’ over 30 m is more realistic for large specimens.

    I’m curious on how a soft shell tortoise could survive in a world full of large carnivores with bone crushing jaws into adulthood.

  • mrplcole on December 11, 2016

    judging from the pic on twitter, does triceratops have cheeks like it has traditionally?

  • DarkEnder64 on December 11, 2016

    Cool but… why Leptoceratops hasen’t any faethers ??? He was so cute with…
    Sorry for taht weird language, I’m french.

    • Paleosir on December 13, 2016

      Parce que Leptoceratops n’a pas de preuve pour des plumes.
      Seulement une espece de Psittacosaurus, qui vivait plus plus tot.

    • Paleosir on December 13, 2016

      No direct evidence for Leptoceratops.
      Only in one species of Psittacosaurus, which lived way way earlier

  • Turtledragon on December 10, 2016

    Aw I love that Axestemys, turtles are my favorite animal. Dakotaraptor looks great, I can’t wait to play as them! It’ll also be cool to see Leptoceratops in the game as well. 🙂

  • Ian Malcom on December 10, 2016

    Question, why does the snout of the Dakotaraptor look so square and bullish until it’s an adult? I know part of it is due to the fact it hasn’t matched the rest of the skull in size, yet, but the concept art and the 3D model I see seems to round out its snout, in comparison with the square-ish one as it’s younger.

  • Sam on December 9, 2016

    I can’t wait for this game! When will you have an idea of pc stats for this game? Im going to up grade my pc and would like to make sure I can run this awesome game!

  • slimeywoodchip on December 9, 2016

    you guys planning to do something spectacular for #10? Or are we just gonna relax and look at some more softshell turtles?

    • Nick Turinetti on December 9, 2016

      Well we were gonna do something cool, but since y’all love turtles so much we can do that instead

      • slimeywoodchip on December 9, 2016

        Maybe we could do something super cool, but manage to put in a turtle at the end 😉

  • Joseph Lopez on December 9, 2016

    You don’t have to answer my question but i would like to know if the T.rex hatchling will able to call out to it’s father when he or she is in danger.

      • J Lopez on January 5, 2017

        How so? or did you just want to comment “no”.

        • AllosaurAlex on February 11, 2017

          godamm i thought you just wanted a question anwered

  • nonavian on December 9, 2016

    I was so happy to see a new devlog! These models look stunning, honestly. And I’m so excited for the complex digestion system, that will really set the game apart from others while providing more immersion. Keep up the good work, you guys =)

  • Estemmenosuchus on December 9, 2016

    Soft shell turtles are vicious though… Even the little baby ones will do anything they can to bite you 😛

  • John Keane on December 8, 2016

    What happened to RJ?

  • Falcolf on December 8, 2016

    Ack, where’d RJ go? I hope he’s okay! Loving these journals!

    • Hobbes the Tiger on December 9, 2016

      Judging by his recent posts, I think he moved someplace without a lot of wi-fi.

  • Kyle Payne on December 8, 2016

    This game is looking more and more incredible with every DevLog! I can’t wait for the game to be released, but don’t rush anything at the expense of your home lives or accuracy!

  • Kemda on December 8, 2016

    Waiting for a devlog from Saurian is one of my highlights of the day. I’m so looking forward for when the game come out into EA, your work seems extremely interesting and cannot wait for the world your going to create. It’s going to be a boys dream to play a realistic dinosaur game.
    Keep up the good work!

  • Christian on December 8, 2016

    Was in on purposely creepy at the end? Also, if I’m not being lied to by the website, FIRST!

    • Christian on December 8, 2016

      Nvm I did not get first, Gg hunter. Gg.

      • Christian on December 9, 2016

        If you didn’t comment then you were not first…

  • classified on December 8, 2016

    imagine that turtle slurping spaghetti

    • Christian on December 9, 2016

      I don’t even know how to reply to that.

  • Hunter1324 on December 8, 2016

    So you are telling me that you are going to simulate the metabolic and nutritional needs of the animals in the game? Amazing!

    Also that’s one big softshell.
