  1. @Enceos That particular solution is sync issues rather than waiting. Consider the examples here:
  2. Multiplayer with timewarp means you must choose at least one of the following: 1. Sync issues 2. Waiting OP's suggestion chooses sync issues.

    Add proper units!

    I've never understood why this wasn't done from the beginning. You need to use units in the game anyway, why not use real ones? @klgraham1013 has the right idea though: At this point the effort:reward ratio is likely way too high for this to be worthwhile. Maybe if there's a KSP2?
  4. Horizon relative SAS is not a thing in stock. Picture shows Mechjeb's Smartass being used in lieu of stock SAS. It would be very useful for planes to have a "maintain angle of attack" button for SAS. Would make long flights way less tedious.

    Why would they want to pretend that? And why are you proud of it to the point of posting publicly about it?

    Dislike Reactions

    There's also the phenomenon of spite downvoting, when a user gets upset with another user for whatever reason and systematically goes through every post of their history and downvotes all of them out of pure malice. An active poster can lose a thousand Internet points just by setting off the wrong person, whether legit or not. While I'm not a big believer in the value or importance of internet points, this sort of thing does make for hard feelings.

    Dislike Reactions

    I cannot imagine a single use for a dislike button that isn't some form of "make the person feel bad about their post". I also cannot imagine that the forum would be improved by making people feel bad about posting.
  8. If you use mods then don't update your game until your mods have caught up. Problem solved, as it has been since modding became possible.

    A farewell is necessary!

    Good luck to you, Badie. I am sure your enthusiasm and positivity will serve you well in your next endeavor.

    Thankfully. But for a week or two it was gloriously on point, which is about as much as one can ask from a meme.

    KSP Loading... Preview: The Δv per Stage Display

    The best implementation of a visualization for transfer windows I've seen is in the Android game Spaceflight Simulator. Select a target body and it highlights a segment of that body's orbit, a segment that moves along that orbit as the origin body moves. Warp until the target is in the segment and you're good to go. A similar thing is done on the spacecraft's orbit to indicate the proper ejection angle. My description here is not that great, but it's such a good implementation that after seeing it I immediately thought "KSP needs this". Simple and intuitive, with zero information overload. Worth a look if you get a chance.

    KSP Loading... Preview: The Δv per Stage Display

    You literally have all the information to calculate dV by hand from day one, locking the automatic calculation of it behind career unlocks is a terrible idea as it just pushes people back to mods or external tools.

    Do any of you actually use the chat?

    Other good topics: - The superiority of the metric system over Imperial measurement. - SpaceX vs NASA, because they're totally competitors. - The fact that both the USS Intrepid and Kennedy Space Center are better tours for aerospace nerds than the NMUSAF in Dayton. They both have shuttles.

  15. I disagree. The developers haven't been overly shy about breaking saves when it comes to adding features to the game, even post 1.0. Even the cosmetic part revamp is doing it do a small degree. Neither is life support. Literally everyone with the mildest interest in spaceflight knows that you need to bring air, food and water with you to survive in space. It's is unintuitive that it's ignored in KSP, and would be even more counterintuitive if we needed to worry about psychological well-being while ignoring physical. If what you propose doesn't change the game or add a new system, then what does it do, exactly? If we have to make accommodations on craft to keep the crew happy, won't that mean that craft already in flight will not be able to do so? How is that any less save breaking than adding LS? Can't have life support in the thread title and then say it had nothing to do with life support. One could certainly argue that morale is a part of crew support, indeed several of the LS mods implement some variation of it. Not everyone is willing or able to mod their game. This has never been a valid excuse to not include a feature, or to dismiss someone's suggestion.
  16. There are a few draw backs to implementing a telemetry system. They interfere with current save games, it's punishing for casuals, require adding multiple commsats to keep track of, and there is already a very robust telemetry mod community. There are a few draw backs to implementing a better aero system. They interfere with current save games, it's punishing for casuals, require adding multiple stats to keep track of, and there is already a very robust aerodynamics mod community. There are a few draw backs to implementing a spaceplane parts system. They interfere with current save games, it's punishing for casuals, require adding dozens of parts to keep track of, and there is already a very robust spaceplane parts mod community. I think you see where I'm going with this. Nearly every new or improved feature added to the game has these effects, and I don't think the game is the worse for adding them. Further, a space game that makes any claim about realism (and KSP does) is incomplete without life support, full stop. It is the big challenge to making crewed missions in real life, it's baffling that this is omitted after all this time and development. Don't like it? I'm sure you'll be able to turn it off in the settings like the telemetry stuff. Or just run uncrewed stuff.

    Confess your KSP sins

    Share the KSP-related things you really shouldn't have done but did, or things you really should do but haven't. Please commiserate if someone does the same as you, or discuss interesting sins, but please don't criticize other people for their confessions. And please don't post until you've confessed at least one thing. To get the ball rolling, my confessions: I am a mediocre pilot. I can perform almost all maneuvers by hand, but almost none of them very efficiently. I hardly finish any missions. I only actually execute maybe 1/5 of the missions for which I build ships. I love building and problem solving in the VAB and test flights, but I seem to get distracted by another design project before getting around to completing the mission. I've never watched a Scott Manley video. No longer true.
  20. Interplanetary transfer burns can be tricky, especially if the vessel has a low TWR (as is often the case when using nuclear or ion engines). Manouver nodes assume instantaneous burns, so if your vessel has to do a substantially long burn to escape they become inaccurate. One of the techniques to minimize that effect is to split up the single big burn into a succession of smaller burns (sometimes called "periapsis kicking"), but that introduces its own problems: - The time taken completing the interim orbits makes it hard to hit the transfer window precisely. - Ejection angle changes as Kerbin revolves around the Sun, so your periapsis may not be where you want when you make the final burn. To sidestep the above issues, I have applied Kepler's 2nd Law and the Vis-viva equation to precompute a simple series of small burns (300m/s or less) to complete before escape, applicable to any interplanetary transfer from Kerbin: Inital Orbit: 100km circular. Burn 1: Raise apoapsis to 658km, costing 300m/s of ΔV. Burn 2: At next periapsis, raise apoapsis to 2,250km, costing 300m/s. Burn 3: At next periapsis, raise apoapsis to 31,930km, costing 298m/s. Burn 4: At next periapsis, burn to transfer, costing 20m/s plus the remainder of the transfer burn. To hit the transfer window correctly, schedule the first burn for as close to 11 Kerbin days (66 hours) before the ideal transfer time as possible. To get the periapsis at the correct ejection angle, subtract 9.3 degrees from the computed transfer ejection angle for the first burn. It is more important to get the ejection angle correct than the time. Another set of burns for very low TWR craft using burns of about 100m/s, gives burn times of less than two minutes even with a TWR of about 0.1: Inital Orbit: 100km circular. Burn 1: Raise apoapsis to 240km, costing 100m/s of ΔV. Burn 2: At next periapsis, raise apoapsis to 419km, costing 100m/s. Burn 3: At next periapsis, raise apoapsis to 658km, costing 100m/s. Burn 4: At next periapsis, raise apoapsis to 987km, costing 100m/s. Burn 5: At next periapsis, raise apoapsis to 1,471km, costing 100m/s. Burn 6: At next periapsis, raise apoapsis to 2,250km, costing 100m/s. Burn 7: At next periapsis, raise apoapsis to 3,708km, costing 100m/s. Burn 8: At next periapsis, raise apoapsis to 7,409km, costing 100m/s. Burn 9: At next periapsis, raise apoapsis to 34,650km, costing 99m/s. Burn 10: At next periapsis, burn to transfer, costing 18m/s plus the remainder of the transfer burn. To hit the transfer window correctly, schedule the first burn for as close to 15 Kerbin days (90 hours) before the ideal transfer time as possible. To get the periapsis at the correct ejection angle, subtract 12.7 degrees from the computed transfer ejection angle for the first burn. It is more important to get the ejection angle correct than the time. In using these precomputed burns a few times, I have come to realize something that should have been obvious to me: Getting the correct semi-major axis is more important than getting the apoapsis correct. So ideally your Ap+Pe would be as close as you can manage to CalculatedAp+100km, especially for the final interim orbit. Limitations/Assumptions: Calculated assuming instantaneous burns, hopefully the vessel's TWR is high enough for reasonable burn times of the smaller nodes. Assumed no inclination change for the transfer. No normal/antinormal burn components are considered. The last interim orbit is higher than the Mun's orbit, an encounter with it could mess up your carefully laid plans. Useful tools: A transfer window calculator, such as http://ksp.olex.biz/ (simpler) or http://alexmoon.github.io/ksp/ (more complex), to calculate the ideal transfer window's time and ejection angle. There are also mods such as Transfer Window Planner or MechJeb that include such tools in game. Mods for precisely setting the ejection angle of a node, such as PreciseNode, KER or MechJeb. Finally, for those who would like to play around with their own values, here is the spreadsheet I used to calculate the above (xlsx format, please forgive the sparse formatting): MultiburnEscape.xlsx. I release this into the public domain, do with it what you will. Edit: regex was kind enough to expand upon the original spreadsheet and make it more general purpose, get it here: MultiburnEscapeExpanded.xls Questions, comments, or corrections are very welcome. Happy flying!
  21. The Curse client seems to offer some compelling features for keeping mods updated and synchronized, if it works as advertised it would be very useful. Back when the move to Curse was announced, one of the Curse people on the forums mentioned that the Curse client was being updated "this year" to remove ads and support KSP. The year is approaching its end, is there any update on whether this will happen? (If you are about to post some Curse hate, please don't bother and move along to another thread.)

    Oddly enough, that makes you more qualified for the job. Perhaps I'm not understanding, but isn't this something that the bookmark feature of your browser handles nicely? Most browsers support synced bookmarks across devices already.

    SAS: Hold Horizon

    That's not what Persistent Rotation does, to my understanding. It closes the loophole of rotation stopping during timewarp, but doesn't change reference frames or anything. It doesn't do anything with SAS as far as I know. That said, I haven't used it in a while, maybe the scope of the mod has changed.
