v0.22.1 "Foundation" Release Notes

Rocket Science

Some spacecrafts may be broken because of these changes.

Features:

  • thermodynamics was introduced to the game;
  • added re-entry effect;
  • extended Earth and Mars atmospheres density, pressure and temperature calculations up to its maximum altitudes supported by models;
  • [Flight] total rework of all part windows;
  • [Assembly] rocket stages now support undo / redo;
  • [Assembly] added an ability to change root part;
  • [Assembly] you can change side attachments on already placed part;
  • [Assembly] you can configure any module on placed part;
  • [Map] you can now pin any tooltip on right mouse click;
  • fins are aerodynamic surfaces now that can be used to control the rocket;
  • you can disable and hibernate probe cores now to reduce electricity consumption;
  • you can disable reaction wheels;
  • added new fuel pair: kerosene - lox and engines that support it;
  • engine plume was completely reworked;
  • all tutorial windows can be dragged now;
  • added new thermal part category.

New rocket parts:

  • “Razryad-518”, “Zaryad-021”, “Duga-8” liquid fuel engines;
  • General-Purpose Heat Source (RTG) and Multihundred-watt RTG;
  • Payload Fairing Strait Base GO-5;
  • Small Fin;
  • Passive Heat Shields for 0.55 m, 1.2 m and 2.5 m
  • Passive Radiator Panel and Passive Radiator R-2.

Part changes:

  • Basic Fin now have control surfaces
  • “Vega-072” engine was made bigger and now requires star socket to attach to;
  • tweaked ISP and thrust for “Iskra-758”, “Energia-C8.95” and “Yuzhniy-348” engines to be inline with real analogs;
  • Structural Adapter 1.2-Cube and Structural Adapter 1.2-Module were moved from structures category to adapters.

Changes:

  • flight part window now opens on right mouse click for consistency with assembly;
  • engine system performance was increased by a factor of 5 in some cases;
  • engine heat emission is no longer fake;
  • reworked “warp to” algorithm, it is now much more precise;
  • improved precision at which drag data is baked;
  • reaction wheels consume energy evenly (previously small wheels consumed first);
  • camera will continue to follow spacecraft if its command module was destroyed;
  • [Assembly] you can now open part config by right clicking on part;
  • [Assembly] removed angle restrictions from all socket types for attached part rotation;
  • [Assembly] you can’t reattach already attached part to another one;
  • [Assembly] significantly improved “Reset all stages” algorithm, that composes stages better now;
  • all selection and hover outlines now brighter;
  • increased electricity capacity up to 2x for all batteries, probe cores and command modules;
  • collapsed solar panel partially produce electricity, reduced by amount of area hidden from the Sun;
  • solar panels energy production now depends on distance to the Sun.
  • added “burnTime” into engines tooltip. This is the amount of time an engine can burn in vacuum continuously without overheating.
  • added area and volume parameters to all tooltips;
  • all single side attachments were rotated 90 degrees to be consistent with the direction of line attachments;
  • some positions of side attachments were swapped to better support changing them on already placed part;
  • cleanup a lot of code and assets related to old timeline system;
  • build size was reduced by 2 GB.

Fixes:

  • when clicking on item on parts panel, click event happens twice;
  • reaction wheels consume 2x time more energy than in spec under heavy load;
  • Rocket does not reset if you make changes to it and then exit to space center via main menu;
  • if you create new rocket, not make any changes to it and then try to exit from editing mode, not saved window is not shown;
  • orbit raycast sometimes not working on highly eccentric orbits (again).
  • game freezes when entering atmosphere on high time warp;
  • sometimes rocket parts suddenly rotate after coupling;
  • [Assembly] center markers get wrong positions if you move spacecraft and then attach any part to it;
  • [Assembly] part resets its rotation when reattaching from one socket to other;
  • navball autocorrection buttons not change state, when autocorrection was changed from command module window;
  • Seeker Decoupler can not be clicked during the flight
  • exception when changing part config when part is not attached to the rocket;
  • sometimes fuel indicator near navball stuck after decoupling;
  • rocket with extended landing struts / solar panels has incorrect bounds when loading from save;
  • wrong tooltip for reaction wheel status indicator;
  • countless bugs tied to old flight window system;
  • stage loses selection outline, when stage button was pressed and there are no more stages left;
  • all aerodynamic surfaces have wrong position of lift force application point;
  • if aero surface had no control surface, it doesn’t change when selecting any other one in part config;
  • you can not hover or select engine during the flight if it was placed inside tail block 0 and was smaller that it;
  • when spacecraft is in physics simulation, time in spaceport is at 10x speed, not 1x
  • infinite exception loop, when you have part selected with symmetry, and then closing spacecraft with changes reset;
  • exception related to orbit panel when you first time load flight.
