Flight Plan

Plan your (Space) Flight! Fly your Plan! Handy tools to help you set up maneuver nodes that will get you where you want to be. Making spaceflight planning easier for Kerbal Space Program 2 one mission at a time.

NOTE: This mod draws heavily on some core MechJeb2 code that has been adapted to work in KSP2, and would not be possible without the kind and generous contributions of Sarbian and the MechJeb development team! It is not the intent to replicate all MechJeb2 features and functions in this mod, but merely to make some handy maneuver planning tools available for KSP2 players. While you may be able to create some useful nodes with this mod, you'll still need to execute them accurately! Also, understanding some basic mission planning will be very usful for those employing the tools in this toolbox.

Compatibility

• Tested with Kerbal Space Program 2 v0.1.2.0.22258 & SpaceWarp 1.1.3
• Requires SpaceWarp 1.0.1+
• Requires Node Manager 0.5.2+
• Optional, but highly recommended: Maneuver Node Controller. See capabilites described below.

Installation

1. Download and extract BepInEx mod loader with SpaceWarp 1.0.1 or later (see link above) into your game folder and run the game, then close it. If you've done this before, you can skip this step. If you've installed the game via Steam, then this is probably here: C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program 2. If you complete this step correctly you'll have a BepInEx subfolder in that directory along with the following files (in addition to what was there before): changelog.txt, doorstop_config.ini, winhttp.dll
2. Install Node Manager 0.5.2 or later (see link above). From the NodeManager-x.x.x.zip file copy the BepInEx folder on top of your game's install folder. If done correctly, you should have the following folder structure within your KSP2 game folder: ...\Kerbal Space Program 2\BepInEx\plugins\node_manager.
3. Download and extract this mod into the game folder. From the FlightPlan-x.x.x.zip file copy the BepInEx folder on top of your game's install folder. If done correctly, you should have the following folder structure within your KSP2 game folder: ...\Kerbal Space Program 2\BepInEx\plugins\flight_plan.

Features

Display Current Target Selection

• Drop Down Menu for easy selection of Celestial Targets

Own Ship Maneuvers

• Circularize at Ap
• Circularize at Pe
• New Pe (user specified value) - planned for next Ap
• New Ap (user specified value) - planned for next Pe
• New Inclination (user specified value) - if e < 0: Planned for cheapest AN/DN, otherwise planned for ASAP

Maneuvers Relative to the Selected Target (only available if a target is selected)

• Match planes with Target at AN
• Match Planes with Target at DN
• Hohmann Transfer to Target

Display Status of Last Command

• Normal/Good results are shown in Green indicating a maneuver node was generated and it's ready for you to execute it. Don't forget to get your craft pointed in the right direction first!
• Warnings and Cautions are shown in Yellow indicating a node was generated, but you should inspect it carefully first and may need to modify it.
• Failures are shown in Red indicating no node has been generated with some clue as to why.

Game Input Enable/Disable Status

• To prevent the things you type in a user input field from passing through to the game and affecting things in odd ways, the game input is automatically disabled when you click inside a text input field. This will cause the game to not respond to your mouse or to anything you type, although you can freely type what you need into the input field. Typing a "." as part of a decimal number will not increase your time warp setting, and using the 1 and 2 keys on your number pad will not mute the game or the music. To restore full functionality for keyboard and mouse inputs simply click anywhere else other than the text input field. Closing the Flight Plan GUI will also have this effect.

Integration with Maneuver Node Controller, v0.8.3+

• If Maneuver Node Controller (v0.8.3 or later) is installed, and if the Launch Maneuver Node Controller configuration setting is Enabled, then when you activate an experimental node creation function the Maneuver Node Controller mod will automatically be brought up if it is not already up. This can make it easier to evaluate and adjust nodes constructed using experimental functions (those listed under Planned Improvement below)

NOTE: At this time Flight Plan has no capability to execute nodes - it just helps you plan them. Getting a Good result in the status does not mean your craft is pointed in the right direction or is otherwise ready to execute the node, but rather that the node is ready for you!

UI Screens

In addition to the basic UI screen above the UI will automatically asjust to offer capabilities relevant to the current orbit and selected target.

Selecting a Celestial Target with the Drop Down Menu

With a Local Object Selected (selected target is orbiting the same body your vessel is)

Configuration Parameters

This mod includes a number of user configurable parameters which can be accessed through the SpaceWarp configuration screen. Press Alt + M to pull up the SpaceWarp Mod dialog, and select the Open Configuration Manager button at the bottom to display the list of installed mods with configurable settings. Clicking on the Flight Plan entry will display the ionterface shown above. There are tool tip strings which describe what each setting does. Using the configuration parameters you can change a variety of things such as how long a status message sticks around before it start to fade, and also how long it will take to fade.

NOTE: The following settings are dyanically managed and may be usted by the user while the game is running. All others will require exiting and restart to take effect.

• Experimental Features: Enable/Disable
• Launch Maneuver Node Controller: Enable/Disable
• Status Fade Time: Seconds
• Status Hold Time: Seconds

Planned Improvement / Experimental Functions

Work In Progress developmental features may be enabled by switching on the Experimental Features in the mod's configuration screen. You will need to restart the game for this setting to take effect, but it will allow you to play with some broken toys if you like. As these featuers mature and become realiable enough to use they will be moved up into the main feature set avaialble without turning on the Experimental Features setting.
