  1. Hm I don't really get what Krakensbane is doing, but I just took a short look at the code at github in USI_ModuleWarpEngine.cs. Apparently to move the ship the current vessel position is taken and then krakensbane is moved to a new position based on old vessel position and and a jump distance based on the warpdrive operation. If this is working in a kerbol relative coordinate system wouldn't it be enough to just add the speed (multiplied by physics step) of the object I currently orbit to the ps vector in line 314? I guess if I am within the SOI of a moon this would actually be needed to be applied recursive to apply the speed of the planet too. The thing I actually really like about this warp drive is the ability to make small precise course correction and directly see the new orbit (compared to the one from KSPI (last used version: KSPInterstellar-v0.11)), so enforcing a minimal throttle setting really does not sound appealing for me. Unfortunate without further guidance hints its very hard once the relative speed is low and the dirty old tricks like gravity adjusting extremely close to the sun and via extreme but precise (mechjeb landing guidline information) aerobrake maneuvers do no longer work because in both cases the ship is converted into a fiery ball of molten plasma :-), so precise control is more important than ever.
  2. Hello not sure if this a bug or a feature. Basically I put a ship into a polar duna orbit by jumping into the SOI and doing a number of careful aerobrakes and realignment jumps. Turns out that an awful (real)time inefficient way to go there, but ok thats the price to avoid waiting for an ingame launch windows. After scanning for ore I tried to change my orbit into an equatorial orbit by some other jumps, but the ship behaved really erratic. Basically at low warp speeds if flow backward or in completely wrong directions and only by going faster stuff began to make sense. I thought there was some internal screwup in the algorithm, but now I realize that the warp drive seem to move the ship (or the rest of the universe) relative to the sun and not relative to the object within the SOI I currently are. This does not really matter if the vessel speed is way faster than the planet orbital speed, but makes navigation almost impossible if the speed is matched, because the navball is basically fully useless then. Is this behavior really desired or some kind of bug? Note: I have only used the speed conservation method so far and have version WarpDrive_0.2.1 installed.
  3. Hello, I have two new findings (v0.5): 1. The craftURL in sat-1.cfg does not match the case of the craft name. Needs to be changed to Mil-sat-1.craft to let the target spawn under linux. 2. I think you use the wrong Parameter for mission sat-7.cfg. I just tried the mission and after successfully destroying the target the counter is still running (or actually seem to have started counting). I think instead of setting name and type to 'Duration' you wanted to set them to 'Timer' instead so they count down from the start.
  4. if you want to rely fully on mechjeb you can go like this: 1. ascend autopilot into something like 75 km (the lower the better, but you should avoid falling back into the atmosphere, so 75 is what I usually use) 2. select mun and use hohman transfer to target. Tweak node to get the closest encounter match your desired orbit high and execute it 3. fast forward to the SOI change (the new handy '>>' buttons) 4. use the circularize feature, choose @ periapsis and execute it Not a single 'I win'-button but close enough :-)
  5. Hello nightingale, I have encountered two bugs while playing with contract configurator v1.0.4 and v0.4 of 5dims military contract pack (running BahamutoDs_Armory-v0.8.2). While doing the first mission I first noticed that the targets are not correctly marked as destroyed in the contract window: Originally everything locked fine, but then the initial targets changed back to 'x' when I hit more targets. I then tried quicksaving and quickloading which results in everything marked as incomplete. Upon destroying the last target the mission finished successful trough, so this may be a pure visual thing. Btw: Your recent change to consider a target destroyed if only debris or 'subvessels' remain seems to work like a charm. Thanks for that I then broke my plane upon landing. This triggered the mission finished event multiple times: I reverted back to my quicksave and landed my plane in one piece. I had 100 science points less, so apparently 'mission finished' was triggered three times and its not just a visual problem. Another thing I noticed is that there are a lot of exceptions coming up when the vessels are spawned. I have ExceptionDetector-v.1.1 installed and when I accept a mission the windows comes up. They stop after a scene change trough, so there is a clear workaround.
  6. Hello, just want to notify you that you seem to have messed up 1.3.3 slightly. https://github.com/severedsolo/KerbinSpaceStation/releases lists 1.3.2 first and both release are indicated to be based on commit bbcbd95.
  7. Hello, given that the engine table @ http://wiki.kerbalspaceprogram.com/wiki/Parts is out of date I decided to run my own calculations. Following the concept 'why solve a problem when you can solve a metaproblem instead' I decided to write python script to parse the actual cfg files . The script is quiet ugly and creates a big wall of text as output, but so far is seem to fulfill its goal This is the primary output: partname , cost, mass, thrust_atm, ISP_atm, TWR_atm, thrust_vac, ISP_vac, TWR_vac, gimbal, EngineType, max_atm(ISP) IX-6315 "Dawn" Electric Propulsion System , 8000, 0.25, 0.048, 100, 0.02, 2.000, 4200, 0.82, 0.0, Electric, 1.2(0.001) 24-77 "Twitch" Liquid Fuel Engine , 400, 0.09, 13.793, 250, 15.64, 16.000, 290, 18.14, 8.0, LiquidFuel, 7.0(0.001) 48-7S "Spark" Liquid Fuel Engine , 200, 0.10, 16.200, 270, 16.53, 18.000, 300, 18.37, 3.0, LiquidFuel, 7.0(0.001) T-1 Toroidal "Aerospike" Liquid Fuel Engine, 3850, 1.50, 153.529, 290, 10.44, 180.000, 340, 12.24, 0.0, LiquidFuel, 20.0(0.001) LV-1 "Ant" Liquid Fuel Engine , 110, 0.02, 0.540, 85, 2.75, 2.000, 315, 10.20, 0.0, LiquidFuel, 3.0(0.001) LV-1R "Spider" Liquid Fuel Engine , 120, 0.02, 1.793, 260, 9.15, 2.000, 290, 10.20, 8.0, LiquidFuel, 8.0(0.001) LV-909 "Terrier" Liquid Fuel Engine , 390, 0.50, 14.783, 85, 3.02, 60.000, 345, 12.24, 4.0, LiquidFuel, 3.0(0.001) LV-N "Nerv" Atomic Rocket Motor , 10000, 3.00, 13.875, 185, 0.47, 60.000, 800, 2.04, 0.0, Nuclear, 2.0(0.001) LV-T30 "Reliant" Liquid Fuel Engine , 1100, 1.25, 200.667, 280, 16.38, 215.000, 300, 17.55, 0.0, LiquidFuel, 7.0(0.001) LV-T45 "Swivel" Liquid Fuel Engine , 1200, 1.50, 168.750, 270, 11.48, 200.000, 320, 13.61, 3.0, LiquidFuel, 6.0(0.001) RE-M3 "Mainsail" Liquid Engine , 13000, 6.00, 1379.032, 285, 23.45, 1500.000, 310, 25.51, 2.0, LiquidFuel, 9.0(0.001) Mk-55 "Thud" Liquid Fuel Engine , 820, 0.90, 108.197, 275, 12.27, 120.000, 305, 13.61, 8.0, LiquidFuel, 9.0(0.001) RE-L10 "Poodle" Liquid Fuel Engine , 1300, 1.75, 60.714, 85, 3.54, 250.000, 350, 14.58, 4.5, LiquidFuel, 3.0(0.001) RE-I5 "Skipper" Liquid Fuel Engine , 5300, 3.00, 568.750, 280, 19.35, 650.000, 320, 22.11, 2.0, LiquidFuel, 6.0(0.001) S1 SRB-KD25k "Kickback" Solid Fuel Booster , 2700, 4.50, 599.474, 170, 13.59, 670.000, 190, 15.19, 0.0, SolidBooster, 7.0(0.001) O-10 "Puff" MonoPropellant Fuel Engine , 150, 0.09, 9.600, 120, 10.88, 20.000, 250, 22.68, 0.0, MonoProp, 4.0(0.001) CR-7 R.A.P.I.E.R.

So basically I calculated how much payload a single engine can accelerate for various delta-v values starting from a predefined TWR ratio and which engine has the best payload fraction for a given TWR and delta-v value. The generated output is the following big wall of text. Some limitations: - values assume a fuel tank to fuel weight ratio of 1:8, so only the values for the LFO engines should be correct --> affects Dawn, Nerv and all solids - electric energy is not considered --> affects Dawn In a nutshell the result seem to be: - For vac. usage the LFO engines are quiet similar (I had expected that the vac optimized engines come out much better, but apparently they are just primary weak under atmospheric conditions). - The monoprop engine seem to loose flat out and the calculated values are even too good, considering that monoprop tanks have a worse mass fraction than 1:8 - While the LV-N is already quiet good for low delta-v values it only starts to shine when the delta-v gets in the 4 digits range - The 48-7S is finally no longer imba Engine comparsion for single stage performance based on ISP_atm and thrust_atm and an inital TWR of 1.20 possible single stage payload [t] for various delta-v values 100 200 500 1000 1500 2000 2500 3000 3500 4000 4500 5000 5500 6000 Mk-55 "Thud" Liquid Fuel Engine : 7.9 7.6 6.5 5.1 3.9 2.9 2.0 1.4 0.8 0.3 --- --- --- --- LFB KR-1x2 "Twin-Boar" Liquid Fuel Engine : 142.3 136.2 119.0 94.2 73.5 56.3 42.0 30.0 20.0 11.7 4.8 --- --- --- IX-6315 "Dawn" Electric Propulsion System : --- --- --- --- --- --- --- --- --- --- --- --- --- --- 48-7S "Spark" Liquid Fuel Engine : 1.2 1.2 1.0 0.8 0.6 0.5 0.3 0.2 0.1 0.1 0.0 --- --- --- Kerbodyne KR-2L+ "Rhino" Liquid Fuel Engine: 71.0 65.7 51.7 33.4 19.8 9.7 2.2 --- --- --- --- --- --- --- LV-1R "Spider" Liquid Fuel Engine : 0.1 0.1 0.1 0.1 0.1 0.0 0.0 0.0 0.0 --- --- --- --- --- RT-10 "Hammer" Solid Fuel Booster : 15.8 14.6 11.3 7.2 4.3 2.2 0.7 --- --- --- --- --- --- --- LV-1 "Ant" Liquid Fuel Engine : 0.0 0.0 0.0 --- --- --- --- --- --- --- --- --- --- --- RT-5 "Flea" Solid Fuel Booster : 13.6 12.5 9.6 5.9 3.4 1.6 0.4 --- --- --- --- --- --- --- LV-T45 "Swivel" Liquid Fuel Engine : 12.3 11.7 10.1 7.8 5.9 4.3 3.0 1.9 1.0 0.3 --- --- --- --- RE-I5 "Skipper" Liquid Fuel Engine : 43.4 41.5 36.3 28.7 22.5 17.2 12.8 9.2 6.2 3.6 1.5 --- --- --- LV-909 "Terrier" Liquid Fuel Engine : 0.6 0.5 0.1 --- --- --- --- --- --- --- --- --- --- --- S1 SRB-KD25k "Kickback" Solid Fuel Booster : 43.1 40.0 31.6 20.6 12.4 6.4 1.9 --- --- --- --- --- --- --- O-10 "Puff" MonoPropellant Fuel Engine : 0.7 0.6 0.4 0.2 0.1 --- --- --- --- --- --- --- --- --- BACC "Thumper" Solid Fuel Booster : 20.3 18.8 14.9 9.8 6.0 3.2 1.2 --- --- --- --- --- --- --- LV-T30 "Reliant" Liquid Fuel Engine : 15.1 14.5 12.6 10.0 7.7 5.9 4.3 3.0 2.0 1.1 0.3 --- --- --- RE-M3 "Mainsail" Liquid Engine : 106.6 102.1 89.6 71.6 56.4 43.8 33.2 24.4 17.0 10.8 5.7 1.4 --- --- 24-77 "Twitch" Liquid Fuel Engine : 1.0 1.0 0.8 0.6 0.5 0.3 0.2 0.2 0.1 0.0 --- --- --- --- LV-N "Nerv" Atomic Rocket Motor : --- --- --- --- --- --- --- --- --- --- --- --- --- --- RE-L10 "Poodle" Liquid Fuel Engine : 2.8 2.2 0.8 --- --- --- --- --- --- --- --- --- --- --- CR-7 R.A.P.I.E.R.

  8. I was playing around with 5dims mod yesterday too and noticed similar behavior. It have the feeling that if the command pod is destroyed first TargetDestroyed is immediate triggered, but if another part overheats first and splits the command pod off the remaining (but now passive) stuff is set to debris and renamed, but the mod starts to track this. In the contract window the goal destroy 'drone-x' changed to destroy 'drone-x debris' for me. So at least for 5dims mission pack it would likely be more useful if such a reclassification would be detected and be enough to trigger the goal.
  9. Hello, I have problems getting the initial contract to launch a station core to complete. I have fulfilled every goal apart from the supposedly optional 'include a cupola' for which I miss the technology so far and I use the basic non-deployable solar cells (again missing technology). With my station core selected in orbit all goals apart from the cupola one have the green check-mark. While locking at it in the contract center I get this output: I guess its harmless that the lvl3 items are back to incomplete once the lvl2 state is set to Complete, but then its seems like the last one is not optional Any hints what I am missing or where I shall look? Using 1.3.1 of this mod and 1.0.2 of ContractConfigurator
  10. Hello, I downloaded v0.4 and tried in combination with BD amory 0.8. So far I didn't finished anything trough. Thinks I noticed during initial testing: - I get the plane as expected now, but apparently aero model of 1.0.2 seem to disagree that this thing can fly - When I accepted the first training mission and go to the tracking station or launch a vehicle for the first time the log gets swarmed with this messages (4MB logfile after 30min kerbal runtime): [EXC 13:15:01.859] NullReferenceException: Object reference not set to an instance of an object Part.ModulesOnStart () Part+.MoveNext () [EXC 13:15:02.006] NullReferenceException: Object reference not set to an instance of an object Part.requestResource (.Part origin, Int32 resourceID, ResourceFlowMode flowMode, Double demand, Int32 requestID) Part.RequestResource (Int32 resourceID, Double demand) ModuleCommand.CheckControlSourceState () ModuleCommand.FixedUpdate () I suspect kerbal isn't fully happy with the way the targets are generated. This stops after going back to the space center and switch to the vessel again. Ok next step is building a plane that flies. Thanks to your tech-tree changes I have unlocked more than kinetic impactors now
  11. Hello, I tried v0.2 with kerbal 0.90 some days ago on linux and had problems with the provided crafts due to case sensitive file systems. Your spelling in /ContractPacks/5dim/ships/ is not consistent with the spelling in the cfg files. I observed this first on the initially provided plane. To actually get the plane I had to change the filename from 'drone-1.craft' to 'Drone-1.craft'. I guess at least all drone-x.craft files don't have fitting names, but kerbal 1.0 came in the way so I temporary stopped messing around with this addon and try to relearn how to build a rocket instead :-)
  12. I have not played around with it, but I guess it is sufficient to extend the "AllowableResources = Karbonite" line. From my understanding the TechnologyUnlocks list only ensures that you don't get the contracts without being able to fulfill them. But if this understanding is correct then the configuration may be a bit lacking because "collect 2800 units of antimatter" is likely a quiet different beast than "collect 2800 units of Karbonite" :-)
  13. I would really prefer if construction would continue when the vessel is unfocused. My experience so far is that the energy supply is not really an issue and due to the fact that construction usually takes multiple days effects like eclipses don't have much of an influence. Given the fact that I need to put smart Kerbals in my construction craft I think it is save to assume the guys ensure that the vessel is kept oriented to the sun such that the solar arrays produce at least 90% of their nominal power on average. (Ok we are in role-playing terrain now given that unfocused craft don't rotate on their own, but who cares) So my proposal is to allow background construction. If you want to ensure that at least a reasonable power supply is present you could limit the construction speed under this conditions such that no more than 90% of the nominal solar power is necessary. Other power generation methods like the kethane powered generators may be more problematic so maybe only solar and rtg's should be considered. Even then it would be a huge comfort increase compared to the current solution and I guess for 'normal' vessels this should be a quiet good estimation.
  14. For me all experiments got a "finalize results"-button while still attached to the station. You have to press this button before releasing the experiment return craft. If you get said message after undocking its basically a warning that you have just screwed up. I don't know if you can dock again to finalize it correctly or if you need to quickload/send a new experiment.
  15. I think the landing (at least sometimes) triggers the "launch new vessel" part of the mission and now silence please before ethernet tries to fix this
