[0.22] Extraplanetary Launchpads Legacy Thread

[Spazmatism]

Is there a reason I can't find the debug setting in the launchpad part.cfg?

[taniwha]

Is there a reason I can't find the debug setting in the launchpad part.cfg?

Yes. You don't need it. If you don't have Kethane installed, it will (or should) auto-enable. If you do have Kethane installed, then why would you want it unless actually debugging?

[greg12]

So, I found a problem. I built a base on Minmus with Kethane and EL. I get all the resources to able to spawn my rocket on the launchpad. After I built the rocket all the resources stayed in the tanks. nothing get removed to fill up the spawned rocket. So now, I can spawn anything and I don`t need to go mining because the resources not going to be taken from the tanks. What should I do to fix this?

purge the obviously possessed launch pad

[taniwha]

Yeah, it sounds like you've got a pad with debug enabled. just delete the line from the part.cfg. EL now checks for Kethane and sets the mode automatically if Kethane is not present, so third-party pads no longer need to include the debug setting.

You mean it may be possible to use the ship selection from EPL in OSY instead of launching and teleporting the ship to the shipyard? That would be very cool! It somehow feels wrong to have to launch from KSC first, then catapult the vessels to your yard. I know there isn't much technical difference in result (other than the wait for the physics shift jumping back and forth) but I definitely would prefer this method used in OSY.

[Spazmatism]

Yes. You don't need it. If you don't have Kethane installed, it will (or should) auto-enable. If you do have Kethane installed, then why would you want it unless actually debugging?

Can I still write it in with kethane installed? I want to keep kethane because I have some working ships using kethane that I don't want to despawn, and sometimes I play without cheating.

Hi,

The center of mass and the center of thrust on the "launch pad 2" seem to be misaligned. When I try to fly it using its own rockets, it leans forward and eventually starts spinning, which makes it uncontrollable. No other part was connected to it when this happened.

I didn't see another post about the same issue, so I wasn't sure if this was a bug or some problem with my installation.

Can you guys help me out? Thanks.

[BigOto2]

Sounds like an issue with the pad itself not having enough control authority. But attaching reaction wheels doesn't work well because of another issue, that also makes it seem to me that the Launch Pad 2 is impossible to use...

It seems sensible to attach parts such as a docking port that would allow other modules to be connected, for example one with a Rocket Parts tank. But all of the parts move, and when I unfold it, none of the attached parts move with it. They just get weirdly suspended in the air where the attachment points used to be before the whole thing moved. So it's basically impossible to attach anything to it, which means transferring resources to it is also impossible without another addon for it.

Am I overlooking something here?

That is the case. I am posting the modified dll. I am hoping skykooler will add this to the mod. It seems to work well. Replace the original dll with mine, and LaunchPadEx parts will function in orbit. However, there is a bug: you will have to "switch to" another spacecraft before having control.

Yes you are =P

use a pancake tank as a base for LP2. OR just get KAS and land LP2 and then slap a pipe connector on it.

http://emlia.org/ksp_shared/Launchpad.dll

As long as you can switch ships within physics distance (ie the to the shipyard and back with '[', ']' ) to get control then that should be fine. If it needs unloading and loading physics by switching out of the area and back it'd be a pain with 0.21, 0.22's extra delays, but still workable.

[taniwha]

spiriteplumber: I've been looking at the code and I think the problem with switching is you copied a little too much from hyperedit: the spawned ship should already be active from when it is first created

[BigOto2]

Thanks, a seemingly odd solution but it sounds like it would work. I think I'll just use KAS for now so it won't be oddly propped up on the ground.

Hi,

The center of mass and the center of thrust on the "launch pad 2" seem to be misaligned. When I try to fly it using its own rockets, it leans forward and eventually starts spinning, which makes it uncontrollable. No other part was connected to it when this happened.

I didn't see another post about the same issue, so I wasn't sure if this was a bug or some problem with my installation.

Can you guys help me out? Thanks.

No one has a solution for this?

Well, continuing off of Khaoscorp's idea, ASAS pancake on the bottom of the pad for better reaction wheel control?

LaunchPad2 was never really meant to 'fly' of its own power. The small engines it has can ASSIST in landing, OR are perfect for bunny-jumping the pad off of a more capable landing craft. A little bit of RCS or SAS and that more than fixes the tiny bit the CoM is offset.

I have honestly had the best luck with landing the pad ontop of a more than capable lander, and then hopping the pad off...this method also leaves the lander to be recycled.

spiritplumber: Sorry if I'm asking a noob question but editting code is a first for me. I unpacked the mod and looked for the ExLaunchPad.cs file in order to edit it according to your very interesting suggestion. I am unable to find a file called ExLaunchPad.cs. Can you help?

The source for the mod is not in the zip to save download size. You can find it on Github.

If you do not wish to compile this yourself, I also linked a modified Launchpad.dll with the functionality. http://emlia.org/ksp_shared/Launchpad.dll I hope the creator of the mod is OK with this as a temporary solution.

spiritplumber: The only problem you really should be distributing the "full"^* source with your dll. (^* just the source to the plugin itself, probably no need to distribute the models too so long as you provide a link).

I don't include the source or link to my github reporsitory because I send my changes to skykooler and he merges them into his tree, which is linked on the front page, pretty quickly, and even that is pushing things.

Once I get some time (I expect some this weekend), I'll integrate your patch into my tree (probably modified).
