[Fun with Save File Editing (Instant Orbits for 0.14)]

I put a station at the GSO height but its orbiting clockwise whereas the planet is rotating anti-clockwise. Anything I can do to reverse the direction of orbit?

INC should be 0 and not 180.

A question: a conventional object will explode if the ground comes within 0.2 m of the node_collider origin. Do the same thing happen to the cart wheels?

[[0.14] Instant Orbit / Debris Generator with bonus Asteroid]

So, is this the final version???

Currently spending most of my time messing around with the plugin system so changing it isn\'t high on my priority list.

Sorry if I sound like a idiot, but what would the instructions be for a Munar orbit at 5KM going over the poles? I\'m not good at the whole 'Eccentricity' thing.....

Semi-major axis = 205000

Eccentricity = 0

Inclination = 90 or 270

[[0.14] Instant Orbit / Debris Generator with bonus Asteroid]

It\'s possible to collide with them but the main problem is that the collider is limited to 256 faces and it\'s the collider that determines what you can collide with.

The asteroid has 1000 faces so the collider only approximates the shape of the asteroid. The collider might be above the visible surface in one area and below the visible surface in another area.

[New Efficient Lunar Challenge]

I had around 40 units of fuel left at the end.

3.5 tanks is probably reaching the limit for Mun landings. 3 tanks might be possible everything would have to be done perfectly. May be a flight computer module could do it.

[[0.14] Instant Orbit / Debris Generator with bonus Asteroid]

Put the program in the KSP save file and run it.

Without any kind of in-depth tracking, it\'s very difficult to intercept an asteroid in Kerbol orbit. Landing isn\'t really possible either since the asteroid surface and the collider don\'t match up.

[New Efficient Lunar Challenge]

Landed on the Mun and returned safely* with 3.5 tanks. ^{*Landed on a hill so constant control imput is required to prevent toppling over and save-scummed once because time warp did not unwarp quickly enough.}

No landing legs, no RCS, no SAS and no parachute.

[[0.14] Instant Orbit / Debris Generator with bonus Asteroid]

So if you try this when you have 2 ships with the same name, will they just translate up to the new orbit height, without changing their position on the orbit, or will they both occupy the same point, and therefore destroy each other, or C, none of the above? I dont know, i havent tried it (I have a mac, and want to wait a little before i try it out)..

All the ships are moved to the chosen orbit. It does not change the position along the orbit.

[[0.14] Instant Orbit / Debris Generator with bonus Asteroid]

I could compile a mac version for you.

This would be nice.

New script in the works; an asteroid field generator.

but really, will there be a mac version?

Sorry, but I neither own a Mac or know how to cross-compile.

[[0.14] Instant Orbit / Debris Generator with bonus Asteroid]

[list type=decimal]

[li]Put the Instant Orbit program in the /saves/default folder in Kerbal Space Program.[/li]

[li]Launch a ship in KSP and immediately return to the Space Center (don\'t end the flight). The ship should still be on the launchpad. Check the Flight Tracking building to confirm.[/li]

[li]If KSP is still open, return to the main Space Center scene and then open the Instant Orbit program.[/li]

[li]Enter the name of the ship that was just launched and then follow the prompts.[/li]

Step 2 is only required if you want to put something directly into orbit. Ships that are already in orbit and have their orbits changed.

All ships with the same name will have their orbits changed.

[JellyCubes Advanced Weapons R&D - Weapons and Other Miscellanea]

Added a railgun version that works with 0.14. Ships now experience recoil when firing. The recoil force may force rip the railgun off your ship.

Ideally, I would like to create a railgun that spawns railgun shells so you don\'t have to manually add them in the VAB and make ammunition a consumable like fuel. A user controlled, turreted railgun version would probably also be possible or maybe a railgun that automatically detects other ships and fires on them.

[[0.14] Instant Orbit / Debris Generator with bonus Asteroid]

The semi-major axis is the sum of the apoapse radius and periapse radius (NOT altitude) divided by two. For a circular orbit, the semi-major axis is equal to the orbital radius.

Kerbin radius = 600 000 m

Mun radius = 200 000 m

Kerbol radius = 65 400 000 m

Geostationary Kerbin orbit semi-major axis = 3 468 400 m

[[0.14] Instant Orbit / Debris Generator with bonus Asteroid]

So instead of just orbiting we can modify those orbits?

The semi-major axis, eccentricity and inclination can currently be changed for any ship. Longitude of ascending node, and craft position along the orbit can\'t be changed.

Only test this with 0.14 x2 but I presume it would work for the other experimental builds.

[[0.14] Instant Orbit / Debris Generator with bonus Asteroid]

A very simple program that can put ships into orbit and change the orbits of any existing ships in orbit. You can put a ship into low Kerbin orbit, geosynchronous orbit, low Mun orbit, Kerbol orbit, anything.

Put the file into the same folder as the persistent save files. Enter the name of the ship and change the orbital parameters. Program will change the orbital parameters of all ships with the same name. Program can be used while in the Space Center so you don\'t have to close KSP.

Backup your save just in case of any errors.

Instant Orbit / Orbit Modifier V0.1

---

A debris field generator that puts debris into orbit. It is limited to debris with only one part. Need to enter every orbital parameter, which may be a good or bad thing depending on your point of view.

Space is so vast that unless you have tens of thousands of parts in the same orbit, you\'re unlikely to hit anything when travelling through a debris field. As a reference, our own asteroid belt only is only around 4% of the mass of the moon.

[Fun with Save File Editing (Instant Orbits for 0.14)]

Instant orbits in 0.14 just got a whole lot easier now since orbital information is stored in the save file. Custom parts may be able to give an instant orbit, but since there\'s no documentation available right now, manual editing will have to suffice. No Battlestar Galactica style jump drives just yet.

I recommend using an editor such as Notepad++ to edit save files.

Instant Orbits

Launch a ship, and while still on the launchpad return to the Space Centre. Open the persistance.sfs file and search for the name of the ship you just launched. You should have something like this:

VESSEL {
	name = Instant Orbiter
	sit = PRELAUNCH
	landed = True
	landedAt = LaunchPad
	splashed = False
	met = 0
	lct = 4.17999990656972
	root = 0
	pos = 0,0,0
	lat = -0.236453328375202
	lon = 27.8244657605096
	alt = 66.4334788515698
	rot = 0.3673681,0.6042479,0.6059003,-0.3644312
	CoM = 0.0008940728,-4.480832,-0.007221261
	stg = 1
	cPch = 0, FLOAT
	cHdg = 0, FLOAT
	cMod = 1, INT
	ORBIT {
		SMA = 300809.642266737
		ECC = 0.994822866051143
		INC = 0.236455925375334
		LPE = 90.2300765984522
		LAN = 117.664053966235
		MNA = 3.14159348003525
		EPH = 4.17999990656972
		REF = 1
		OBJ = 0
	}

Change the sit, landed and landedAt fields to:

	sit = ORBITING
	landed = false
	landedAt = 

Then under the ORBIT section, change the parameters to whatever you want.

SMA = semi-major axis

ECC = eccentricity

INC = inclination

LPE = longitude of periapsis?

LAN = longitude of ascending node

MNA = mean anomaly?

EPH = epoch

REF = body the spacecraft is orbiting (0 for Kerbol, 1 for Kerbin, 2 for Mun)

OBJ = what kind of object spacecraft is (0 for a controllable ship, 1 for ship to be debris)

Instant orbits are even easier in 0.14. You easily change altitude, eccentricity and inclination of orbits now.

Has the added bonus of your ship not exploding into a million pieces too.

Maybe. I\'m really lazy though, so don\'t hold your breath for it.

Could you try to make the bullets have a collision only at their bottom? that way we could stack WAAAAY more stuff...

Use the smaller training rounds. Funny things happen it the bullet travels too fast and the node collider is too small.
