How to make multi-mode engine? [1.3]

UbuntuLinuxKing · October 20, 2017

So,

I'm attempting to combine two engines in my mod into one with a mode for each engine, like the Afterburning Turbofan. However, I'm confused at what I have to do, even after looking into stock CFGs with multiple modes. Can anyone help me with this?

Thanks!

I found this in the R.A.P.I.E.R. engine code:

MODULE
	{
		name = MultiModeEngine
		primaryEngineID = AirBreathing
		primaryEngineModeDisplayName = #autoLOC_6001897 //#autoLOC_6001897 = AirBreathing
		secondaryEngineID = ClosedCycle
		secondaryEngineModeDisplayName = #autoLOC_6001898 //#autoLOC_6001898 = ClosedCycle
	}

Start with a full copy of the config for one of the working engines in game, then slowly add in your changes and customizations Until you have what you want.

I can't do that, though - I've already set up all the animations for my engine in my original CFG. I tried copy-pasting some of the stuff in the Turbofan CFG, but the only thing that changed was that a "switch mode" button appeared on the rightclick menu. It doesn't do anything, unfortunately.

Post config file for your engine here.

Here you go:

You have double closing bracket in your config after first "ModuleGimbal", here:

	MODULE

}

Actually, you don't need two gimbal modules and two SurfaceFX.

Here is config with corrections, it should work:

Also, I have noticed that second engine mode has 4x more thrust, and no other changes comparing to first engine mode. Is this intented?

Yes. It's a Kerman Drive, which is essentially a torch drive for KSP. Or an Epstein drive if you've seen The Expanse. The first mode is a Low-G mode for ensuring your Kerbals aren't reduced to a fine paste by the acceleration. The High-g mode is for when you just feel like getting somewhere fast with a probe and/or crushing some kerbals.

Alright, that worked. Thanks! However, in the primary mode, the engine effects don't show up. It still works, but can you explain to me why the plume and smoke aren't showing up? Thanks!

My only guess is second engine mode should have it's own "runningEffectName".

	description = The Kerman Drive is a fusion drive with incredible power AND efficiency. Scientists say it works by fusing Keuterium and Kritium to create plasma, which is then accelerated out of the craft. We personally think it's just witchcraft, but either way it's great for jetting around the solar system. It has two modes: Low-G and High-G. Low-G is limited to 5000kn, while High-G unlocks the drive and allows for up to 20000kn of thrust. KDT is not liable for any damages sustained from crushing g-forces.

Yes. It's a Kerman Drive, which is essentially a torch drive for KSP. Or an Epstein drive if you've seen The Expanse. The first mode is a Low-G mode for ensuring your Kerbals aren't reduced to a fine paste by the acceleration. The High-g mode is for when you just feel like getting somewhere fast with a probe and/or crushing some kerbals.

Insert these into the LowG mode's ModuleEnginesFX node. This enables th spool effect and gradual, tolerable acceleration. Lower values mean a longer spool time. Examples of the difference in spool time are most stock jet engines with 0.5, and the Panther in Wet mode (which spools the quickest) with 0.8, and the Goliath airplane engine with 0.06 and 0.25 which should take really, really long. My example will have your engine taking roughly a minute to reach full thrust and somewhere less than that to stop thrusting.

useEngineResponseTime = True
engineAccelerationSpeed = 0.15
engineDecelerationSpeed = 0.3

Also, this... :wink:

MODULE
{
	name = MultiModeEngine
	primaryEngineID = AirBreathing //You can safely change this
	primaryEngineModeDisplayName = LowG
	secondaryEngineID = ClosedCycle //You can safely change this too, and in its ModuleEnginesFX node
	secondaryEngineModeDisplayName = HighG
}

MODULE
{
	name = ModuleEnginesFX
	thrustVectorTransformName = Thrust
	engineID = AirBreathing //You can safely change this
