Children of a Dead Earth is an upcoming hard sci-fi space warfare simulator. On this blog I will post developer musings, random tidbits, and the like. A quick primer on how scientifically accurate Children of a Dead Earth is:
Realistic Orbital Mechanics – With a full N-Body Simulator, all manner of orbital dynamics are supported, from Orbital Perturbation, Gravity Slingshots, Hyperbolic Trajectories, and Lagrange Point Orbits. By comparison, most other games use the Patched Conic Approximation, which is extremely inaccurate at certain scales, and can’t simulate most of the above features.
Realistic Scale – The solar system is modeled perfectly to scale. The sizes of planets and moons are just as enormous as they are in real life, and the distances between planets are equally vast. Other games fudge the sizes of planets, or the densities of things, and almost all fudge the distance between planets.
Realistic Technology – Every technology in game was implemented using actual equations from engineering textbooks and white papers, from the exhaust velocity of the nuclear thermal rockets, to the thermal expansion stress of the railguns when firing. You can even tweak the actual properties of these systems to see how they affect their performance, such as altering the length and thickness of your railguns to determine how that affects the inductance, or altering the nozzle length and expansion angle to see how that affects rocket exhaust velocity.
Realistic Space Warfare – All combat in game is a physically and scientifically accurate simulation. Every gun turret draws power not just for firing, but also for the reaction wheels that orient it. Every propellant tank, filled or empty, affects the delta-v and the mass distribution of ships, affecting how the ship will tumble when torqued. Every projectile impact damages each tile of armor based on actual hypervelocity impact studies. Nothing is handwaved, nothing is glossed over.
More on the nitty-gritty details of the game in later posts.
