When I play Minecraft, I usually try to pick the perfect spot to build my house and spend the rest of the game in a relatively small, unchanging area. This is a fun survival aspect, as it gives the player a real motivation to keep the creepers and enderman from destroying all of my hard work, but it also means that I spend almost most of my time in the same biome, which has the same few weather effects. So there needs to be a way to bring adventure to the player who has settled down.
I was thinking, to change things up, it would be a great addition to the game to have a season cycle. Now, I know this has been suggested before and has even been turned into a mod, but hear me out on this.
My system, which unlike the mod I’ve just shown you, is not just an aesthetic addition, is a complete overhaul to the survival system. Because after about the third day of survival, it gets kind of easy, and the game becomes just creative mode. Which is great for creativity, but the survival element of the game is also great, and I believe it can be improved.
So anyway, with added seasons that you can get from the alt shop Minecraft, days would be longer in summer and shorter in winter. Further elaborating on that idea, you could have different weather effects,(more frequent snow in winter, and not just in snow biomes) and less snow during the summer months. The seasons could affect every aspect of your gaming experience: Crops could grow faster during the appropriate seasons (which is actually added in the mod I mentioned), and (most importantly and what makes my idea unique) not at all during winter, forcing the player to stock up for the hard winter months in order to survive. You could even add food spoilage for added tension.
But upon further inflection, I came up with a few things that could possibly be a problem with this new system: there is no good way for the world to remove snow after it’s there. This could be fixed by making snowmelt in high temperatures and during rain. A temperature mechanic would obviously be needed to be added.
Also: the entire world isn’t loaded at once. So if you were in one area of the world for long periods of time and it became winter, then you moved elsewhere while it wasn’t snowing you would notice a straight line between biomes where one side is snowy and the other isn’t. This problem is not unsolvable, however, because this was actually one of the big flaws with the early biome program before it was perfected.
I think that having temperatures affect the climate (so that snow melts in spring or when it rains) would be the best solution. It’s a dynamic that would just make a lot of sense, and it doesn’t seem like a stretch at all from a programming perspective. The temperature could be partially tied to light level, making it an easy implementation.Figures
Abstract experimentally validated soft sphere discrete element method simulation of the granular medium. In this paper, we use the simulation to study the detailed mechanics of undulatory swimming in a “granular frictional fluid” and compare the predictions to our previously developed resistive force theory (RFT) which models sand-swimming using empirically determined granular drag laws. The simulation reveals that the forward speed of the center of mass (CoM) oscillates about its average speed in antiphase with head drag. The coupling between overall body motion and body deformation results in a non-trivial pattern in the magnitude of lateral displacement of the segments along the body. The actuator torque and segment power are maximal near the center of the body and decrease to zero toward the head and the tail. Approximately 30% of the net swimming power is dissipated in head drag. The power consumption is proportional to the frequency in the biologically relevant range, which confirms that frictional forces dominate during sand-swimming by the sandfish. Comparison of the segmental forces measured in simulation with the force on a laterally oscillating rod reveals that a granular hysteresis effect causes the overestimation of the body thrust forces in the RFT. Our models provide detailed testable predictions for biological locomotion in a granular environment.

Introduction
Undulatory locomotion is widely used by organisms living in water [1], [2] and on the surface of the ground [3], [4]. However, thrust and drag forces can differ depending on the physics which govern the body-medium interaction. Small organisms, such as nematodes and spermatozoa, live in fluids where viscous forces dominate and inertia is negligible [1], [5]. Larger swimmers in water propel themselves with forces which arise from accelerating fluid. For terrestrial locomotion of undulatory crawlers like snakes and eels, frictional ground reaction forces provide thrust. Study of the mechanics of undulatory locomotion in varying environments advances our understanding of these organisms. The principles learned from the locomotion of organisms may also facilitate the development of robotic systems that can move efficiently in various environments [4], [6], [7].) [1] and Lighthill's elongated body theory [8] provide insights into the coupled dynamics between the hydrodynamics of media and the kinematics of the animal. Computer simulation which couples computational fluid dynamics (CFD), internal forces, and elastic structures enables examination of neuromechanical control hypotheses and analysis of morphological features beneficial to locomotion (e.g. [9]–[11]).
Granular environments such as sand-covered deserts, beaches, rain-forest soils and leaf litter are common habitats for terrestrial animals. A granular medium has a complex rheology since it can behave both like a solid or a fluid [12]: it remains static under stress until the yield stress is reached, after which it will flow and deform. Accurate equations at the level of the Navier-Stokes equations for fluids have not been developed for granular media. Further, flow visualization techniques in optically opaque granular materials are less advanced than those in fluids (e.g. Particle Image Velocimetry (PIV)). Nonetheless, some principles about the resistive force on an intruder moving within granular media have been revealed. At low speeds (quasi-
