Information Changelog Stats

The mod displays trajectory predictions, accounting for atmospheric drag, lift, etc. Works with the stock aerodynamic model, and also with Ferram Aerospace Research (FAR).

If you have FAR installed on KSP 1.0.5, make sure it's not version v0.15.5.3_von_Helmholtz, as it has an issue that might break your vessel when Trajectories is installed as well. Use the version of FAR v0.15.5.4_Hoerner. Note that FAR versions after Hoerner are also known to be incompatible (trajectory not affected by atmosphere), which will be fixed some time in the future.

Version 2.0.0 for Kerbal Space Program 1.3.1

Released on 2018-02-15

v2.0.0 for KSP 1.3.1

  • 2018-02-15

Changes since the last release

  • Completely new and overhauled user interface, based on the DialogGUI system. Includes (automated) localizations for Russian, Spanish and Chinese (traditional). If you know any of these languages, please consider helping out with translations. Send all Thanks and Kudos to PiezPiedPy for this amazing contribution!
  • In-Flight trajectory vector line and ground marker persistence bug fixed.
  • ModuleManager updated to v3.0.3
  • When combined with FAR, aerodynamic forces calculated on a packed vessel would lead to NRE's. Vessels are now no longer calculated when a vessel is in a packed state. Thanks go to Alex Wang for this bug fix.
  • Higher precision and better performance through more advanced numeric techniques using an RK4 integration method. Try disabling the Cache for more precise predictions, predictions that should not kill your FPS anymore. Courtesy of fat-lobyte aka Kobymaru.

For Developers

  • API changes to help catch NRE's from improper calling of the API methods.
  • New API method HasTarget() checks if a target has been set.
  • Flickering entries bug in the Profiler is fixed :)
  • Added Reset averages & Show zero calls buttons, a Framerate limiter, avg calls and frame counter to the Profiler.

Known Issues

  • Sometimes In-Flight trajectory ground target marker can cover entire screen when camera is close.
