An update that will hopefully put a smile on your faces: error messages have been greatly improved. It should now be within the realm of possibilities to hunt down that bug in your code Also, I've started work on providing globals for the different readings on your navball. Now we're at version 0.22

Could you add Kerbulator to your list of plugins that use your toolbar?

good to hear it's now working for you both. Gives me more time to focus on features instead of bugs.

Sorry, I can't seem to reproduce it. Can you give any more details? Does it happen every time? Was is some sort of fluke once? Does it work, even though you get the errors? Does it go away once you've run a function? Are you in orbit or on the ground? Anyway, thanks for reporting it, I'll keep an eye out for any null-pointer exceptions

I fixed something that looked like this in version 0.21. Are you running the latest version? If so, on what platform are you?

It should be compatible, but must admit I never tested it under linux. I will give it a go when I have access to a linux machine. In the meanwhile, could you perhaps check your KSP.log file in your KSP dir to see if any error messages have been put there? And maybe check the debug toolbar? (Mod + F12)

And the bugfixes are in! Version is now 0.21 Thanks Teseracto

Thanks for the feedback! I've put your suggestions into the Github issue tracker. The bugs I will fix ASAP. New features will come in due time

So, it turns out there is already a mod named Kalculator by agises. A very nice looking calculator, go check it out. I've decided to rename this project 'Kerbulator' instead and created a new thread for it as I cannot change the title of this thread. You'll be glad to hear that now, Kerbulator supports blizzy78's toolbar! I've spend some time making pretty icons for the thing and it looks much better now.

This is the new thread about Kerbulator. Here is the old thread, where the plugin was called Kalculator. Turned out that name was already taken. One of the big joys of Kerbal Space Program is that game progress is not based on experience points, or character level, but based on your own knowledge about orbital mechanics. Maybe this is why I don't like using MechJeb much, its free progress in the game. Inspired by Scott Manley's videos about 'orbital mechanics on paper', I spend an afternoon thoroughly enjoying myself deriving various formulae. Oh, how much fun the creators of MechJeb must have had with it themselves. So I created a mod that lets you put your own formulae in KSP and named it Kalculator Kerbulator. It is a small plugin that allows you to program mathematical equations, run them to see the output and create maneuver nodes. Of course, your calculations need various inputs (like the mass of the body you're currently orbiting, the value of the gravitational constant, etc.) and for this, Kerbulator aims to strike a balance between providing enough useful variables to be productive, and not supply too much information and rob you of the joy of calculating things for yourself. The current guideline is that Kerbulator gives you access to all the various numbers that appear in the vanilla KSP GUI. So, what are you waiting for? Download the plugin or get the source code Read the manual And start learning interesting math Author: Marijn van Vliet License: GPL v3 Feature highlights: Create manoeuvre nodes and alarms (if KAC is installed) based on your calculations Open windows that continuously evaluate your functions and present the result Unicode aware, so you can use math symbols for operators and greek letters for variables Contains a numeric solver to approximate answers that cannot be calculated analytically Edit functions in any editor you want. Returning to the KSP window will reload all functions. Current verion: 0.51 Changelog --------- 0.51 Small bugfix release, thanks to @linuxgurugamer.

Language features: Functions Expressions Lists List unpacking Globals: All celestial bodies Current orbit Orbit of target Target intercept information GUI features: Function list Description of input and outputs Very basic support for error reporting Editor with keyboard Re-scan function on window focus Add maneuver nodes

Not yet. But I'm working on it. Doesn't seem to hard to do. Hardest thing for me is to create a good looking icon

I've added license information. GPL v3.

Sometimes, the Run button didn't work on Windows (I'm on a Mac). Since it's kind of an important button, it's been fixed right away.

Good point. I've added a screenshot

There is a already a mod that does this? Which one? I know that there is KOS, which aims to supply a Kerbal scripting language, and there is ProgCom that emulates a CPU you can program with assembly code. Both of them are capable of performing some math, but their main focus lies elsewhere. Kalculator just wants to do math, and do it well.

One of the big joys of Kerbal Space Program is that game progress is not based on experience points, or character level, but based on your own knowledge about orbital mechanics. Maybe this is why I don't like using MechJeb much, its free progress in the game. Inspired by Scott Manley's videos about 'orbital mechanics on paper', I spend an afternoon thoroughly enjoying myself deriving various formulae.

The current guideline is that Kalculator gives you access to all the various numbers that appear in the vanilla KSP GUI. Kalculator is still a bit rough along the edges, but I'm curious to see what you think and whether there is an actual need such this kind of mod. So, what are you waiting for?
