    You have to run a while loop that checks the targets position at least once a second(but probably more like every .1 seconds or faster) in order to update your target position variable in real time. If you set the position once and never update the variable, it won't change, even if the actual position changes over time. This is why your target seems to drift, as well as the fact that a specific ground position does not always occupy the same PCI coordinates because of the planet's rotation. If you sit motionless on the ground with your PCI coordinates displayed you'll see that everything moves even if it hasn't moved relative to the ground surface itself. The only way to remedy this is to rapidly update the current position like above

    A quick Google search can give you plenty of sources for the equations and explanations of where the terms come from and why the math works out how it does. The info on Wikipedia isn't bad, but it's not easy to understand, so I suggest the NASA.gov pages with the relevant information since it's easier to follow along with.

    @SamTheFox There's another way to do that too, but I can't remember off the top of my head. Either way though, it's as simple as copying the files into the proper folder or just saving them there in the first place lol

    Simple answer: a good bit of math.

    You'd have to calculate a number of things like the Kepler Orbital Elements, the Delta V requirements for a change in your orbit, and some method(s) for converting everything into proper inputs for stuff like throttle, pitch, yaw, etc.

    There's a number of different maneuvers to choose from as well depending on the starting state and target state orbits and craft design/specs. This means many different equations and methodologies to keep track of and implement if you want a fully capable system, and it will challenge you.

    I've personally made most of what I just mentioned in vizzy and made some simple automated maneuver test programs, but I haven't quite taken the time to make comprehensive maneuver program using all those pieces. It's not as difficult as it might seem, you just have to do a lot of research and spend quite a bit of time experimenting with vizzy. If you start off making smaller individual programs for specific maneuvers or calculations, as you learn more you can then combine them into larger more complicated programs and libraries

    @plane918273645 yeah, that's a good point too. You agree to those terms when you sign up lol. If someone wants to use the site, they have to follow the rules or risk losing access. However, if they get banned from the site, there's nothing to stop them from continuing to play the game itself, especially if they legitimately purchased it. But without access to the site, you can't save backups, easily transfer crafts,etc between devices, or use anything made by other players. Some of this is basic functionality for the game which shouldn't be dependent on a seperate website. IDK, it's not really a big deal anyway because most people will go out of their way NOT to get banned, and even if they do, it's not hard to set up a new email address and use a VPN to change your ISP, etc and just make a new account

    I know basically nothing about Mac or iOS, so I can't give you a definite answer. I would assume that much like Windows you'd have to download the mod(s) and remember where they got saved to(preferably you'd make a new folder just for that). Then, depending on where the game itself is stored on your os (for example the C: folder on windows), you'd want to copy an paste the mod files into it. I'm not sure cause I haven't bothered with mods yet, but the game might have a built in mod menu somewhere in the settings, idk. I'm sure other players know alot more about it than me lol

    I don't exactly have that issue, but I can agree that the designer tool in mobile is very difficult to use. It's always in the wrong place at the wrong time, too small for your fingers, and doesn't respond to input sometimes. I wish they could find a better way to give us the functionality, but I don't know how that would work with mobile. If you can afford a Bluetooth keyboard, you can use the same hotkeys as PC and eliminate the need for the button system, but that's not something many players would do

    @Toinkove that's a great analogy, pretty close to what I would've used myself. It's basically how a high school physics teacher would introduce the topic of Newtonian physics to class(along with some kind of visual demonstration involving a toy car rolling down sloped track).

    To add a bit for clarity, acceleration(and deceleration) is always positive because it requires some type of force effecting the body. An object falls toward the ground because of gravitational force(downward acceleration), the air in it's path imparts drag force(upward acceleration), and when the two balance each other then acceleration is 0(terminal velocity). In the absence of these forces(or any others), then an object would never have any acceleration. This is all regardless of velocity or direction of motion/force applied.

    Acceleration is a vector quantity
    A=F•m
    since F is a directional force(vector), m is mass(scalar), and a scalar times a vector is always a vector in the same direction but of a different length.
    Velocity is also a vector and typically represents the path of motion of an object(assuming some outside force doesn't change that), so it's common to accept any acceleration that increases velocity length as positive "acceleration" and any acceleration that decreases velocity length as negative "deceleration". Acceleration can be in any direction though, so it doesn't necessarily mean the velocity vector's length(the actual "speed" of the object) will change with a given acceleration vector, the direction of velocity is instead effected.


    If the angle measures between the two vectors
    [Angle(v)(a)]
    Is less than 90°, then it's likely acceleration, and if the angle is greater than 90°, then it's likely deceleration, but only if the length of v changes respectively.


    PS, I realize there's a lot more to it than that, especially since I'm leaving out angular moment and rotational acceleration, but that's waaaaaay beyond anything I'm capable of explaining in a reasonable manner

    @Toinkove true, but the mobile version always has its own set of bugs and stuff to deal with, so we'll see how that goes. I play a bit on PC too, but don't have a lot of time to do so(unlike mobile, which is pretty much always with me). I have messed around with the most recent PC updates a bit(beta and normal) and I'm excited to see where the devs end up taking it as time goes on.

    So, it sounds like you should probably look up stuff like orbital mechanics and the Kepler Orbital Elements(trust me, the basic idea is easy even if the math behind it isn't). Most new players aren't gonna have much knowledge on the subject, but that's part of the point of the game: learning about the physics and stuff involved in spaceflight. You just have to keep trying and look up stuff that you have problems with(also, continue to ask questions here and/or the discord server).


    Now, to answer your question:
    Inclination is the angle of your orbit relative to the planet's equator. If inclination is 0° then your orbit is perfectly around the equator(from west to east), if inclination is 90° then your orbit goes from pole to pole(south to north). The thing is, inclination can be anywhere from 0° to 180° depending on the direction of orbit over the planet. 180° is the same as 0° except in the opposite direction(east to west instead of west to east).

    For a 100° inclination, you'd want to launch your rocket at either 100° or 280° on the nav sphere(both will give you the same inclination) and hope you don't need to adjust it much(depending on where you launch from, you might have a bit of difficulty getting to the correct inclination). If you do need to adjust things, you can use the burn planner to make things easier, but you'll probably want a tutorial on that as well if you're not familiar with how it works

    Hmmm. Not sure what's going on there, but it must be an error of some sort. I can still download crafts and stuff on mobile no problem(I literally just checked), so it's probably not the site itself, but I don't know for sure. Sorry that's happening to you, it must suck.

    That's not possible with the game as it is. While the mobile version is generally optimized for phones/tablets, it's still basically the same as the PC version just with a slightly modified UI to make up for the lack of keyboard and mouse. Tilt controls(accelerometer) are common on mobile devices and nearly nonexistent on PC, so the devs probably decided it wasn't worth the extra time and effort.


    As a side note, I prefer that this game doesn't have tilt controls because I tend to play while I'm in a car/bus that's moving and the game would pick up the vehicle's acceleration as me tilting the controller. I used to play a racing game with tilt controls until I realized that it was impossible to steer like that in a moving vehicle

    You can't really target it which is probably a big part of why it seems to not be there anymore. For a while there, the only way to target it was to target the general position at a few meters ASL which could be tricky. Then there's the fact that it wouldn't function like a real droneship because it's a structure, and players figured out ways to make functional droneships anyway

    Someone who knows more about this than me will probably correct me if I'm wrong, but I believe it has to do with floating point accuracy just like the limit on physics distance. You can't time warp in atmosphere with engines active because of the lift/drag calculations, and you can't change time warp speed with engines active because the orbital equations are calculated based off time. Ion engines are the exception because the thrust is so low that it doesn't really matter

    I mean, that's already technically a thing, you just have to upload everything to this site manually and then redownload it on the other device(s). That can be time intensive and relies on the user uploading things immediately after making them to minimize the chance of losing them, however it also gives the user control over how much data is being transferred or stored on a device which is much more desirable.

    As great of an idea as that is, I could see some people taking advantage of it to troll or harass others. Still, much like YouTube, there is a good use for it since downvotes would indicate if something is good/useful or not a lot better than upvotes alone(a craft with 50 upvotes alone must be good, but a craft with 50 upvotes and 100 downvotes must be bad). YouTube removed the ability to downvotes videos, and now terrible videos are receiving huge praise because they can't be marked with downvotes, and I can see how that's probably happening here too

    As far as organization of the forum posts goes, maybe try a "master" forum post that has a list of links to individual posts. That way, you still get the benefits of a new post each time while also having an easy way to find all the posts in one spot(that and it doesn't fill your bio page with links lol). All you gotta do is edit the new link in for each new post, or just comment and pin the links

    To add to the previous comments, once you get to the main menu(blue screen with a star and whatever recent craft displayed on top of a play button) if you press the play button it opens a menu with a list of options to play with. The first 2 are the tutorials, one for the craft designer, one for flight view, the next two are the same, but the standard "sandbox" mode, and the rest are challenge missions(still mostly "sandbox" but with specific goals/rules to follow).

    You can go through the tutorials as much as you want, and the challenges are always replayable too. I suggest doing the tutorials a couple more times, then giving it a go at the challenges to learn more and practice different techniques. There's also technically a couple tutorial challenges, one for docking and another for landing a shuttle that are worth checking out.


    Controls are the same across all devices, except for a few optimizations for touch controls/keyboard depending on the device. You can easily and reliably use the nav-sphere and other UI buttons to control any craft without the joysticks, etc. However, the joysticks are easier to use for airplane flight and good in a pinch with rockets.

    Most inputs can be remapped to "sliders" that you can pop up next to the throttle slider and they work the same except in both directions(-1 to 1 instead of 0 to 1). These can be used to control parts of a craft that aren't easily controlled another way such as cargo bay doors, rotators, motors, etc. You can also use them to control individual control surfaces(ie, an airbrake) seperately from pitch, yaw, and roll.


    The power button in the bottom corner is only for activating the next stage, it does not turn things off, only on. If you want to be able to turn things on and off with a toggle, use "Activation Groups". In flight, you can open the AG panel with button on the right side of the screen above the joystick toggle. The AG panel will pop up next to the power button and give you a list of toggleable buttons linked to various parts/systems on the rocket. By default, there 3 AGs set(Landing Gear, RCS, and Solar Panels) but there's a max of 10 AGs per craft(you can get more if you use additional command chips, etc).

    An engine linked to an AG can be toggled on and off without even having to activate the stage it's in(best for aircraft since the engines can't be shut down after the stage is activated).


    My advice is to look up tutorials on YouTube and download so

I can run the game at nearly maxed everything on my PC, but if I actually max out all the settings, it crashes immediately after the first stage activates on any craft.

    No, but that doesn't sound unrealistic for modern long range Air-to-air missiles. Radar guided missiles can use ground based radar and AWACS radar signals for guidance well beyond the range of the radar on the jet that fired it. "Fire and forget" "over the horizon" AMRAAM missiles assisted in such a way are basically standard these days, and can have a range in excess of 400km.

    Shot 1 is an auto-tracking camera program(WIP). Still lacking major functionality, but I'm getting closer to a useable product. Automatically sets the target to the closest non-player craft but also allows the user to select a target from a list of all crafts within the current planet's SOI(for now) at any time. Using a simple motor/rotator setup to "gymbal" the camera on 2 axes coupled to sliders, it automatically tracks moving targets(ie, a rocket launch/landing) along with adjusting the zoom to keep the target in frame(when possible). Currently this is a demonstration model to prove the concept before developing a complete auto tracking camera system for multiple use cases.


    Shot 2 is my first real attempt at implementing a simple PID to make a rocket hover at a predetermined altitude. Results have been lackluster with many hours spent in frustration agonizing over bugs and various implementations of the processes involved. While the PID itself works flawlessly, the current implementation of the overall code makes it nearly useless. Overcorrection and "bouncing" between extremes is inevitable, and even when it seems to balance out close to the target Integral creep causes wild variations in output after a while. Needs more testing and a complete rebuild from the ground up

    It's just a slightly more complex ranking system. It's been redone and added onto because of the shear number of users and how quickly some users got to the original highest rank.

    Each color is split into 4 sub-ranks denoted by 1-3 bars or stars depending on your points. This makes it easier to tell how close someone is to ranking up to another color without doing math. It also just looks cooler like that lol

    A launch tower is stationary, while a gantry moves out of the way. Systems like the Saturn V and Space Shuttle used launch towers(although the quick disconnect systems are technically just small gantries). Soyuz on the other hand uses a wraparound gantry tower that opens from the top like a flower immediately after ignition. A lot of smaller rockets use gantries too. I'm not sure exactly why one system is chosen over the other for different applications, but I'm sure it boils down to economics and the reliability of the rocket in question.
