Help With Rocket Part

[Nicholander]

Yeah, this rocket part I'm making, the HypeDrive isn't working. I set it's thrust to 1000, but when it's in the game, it doesn't even have any actual thrust, (MechJeb says TWR 0, and when I tried launching it, nothing happened) it doesn't have any effects, and the sound I added isn't playing. This is it's .cfg:

        rate = 6.0
    }
}

}

}

Is there something in there which requires an animation, which my part doesn't have? Has anyone else had this problem, and they now how to fix it? If you do now what I'm doing wrong, please tell me how to fix it. Thanks in advance!

Also, why does it say in the VAB that it eats 29 Hype/sec, but there's no parameter in the cfg for that?

Check if you have thrustTransform on your model or if it is set on the config or if the transform you used on the model matches the config.

[Nicholander]

Oh... I don't have thrustTransform, and I don't even know what that is.

[OrbitusII]

Here's an example Unity setup and the compiled part. It's good for seeing how gimbals, fairings, and the basic engine setup work.

[blackheart612]

Check the guides around here, many on the mod development links compilation. You'll be able to make it work in no time.

I would also say you remove the ' scale = 1 ' and replace it with " rescaleFactor = 1 ', then your model has the same size as you modelled it.That's quiete iimportant. To lower the amount of hype it required, you can increase the ISP, you do that with typing a higher number than 700 in under atmospphere curve, as higher the ISP is, it will need less propellant.

Hope I could help

Hmm... I looked at (I loaded it up in Unity) And it doesn't even seem to have anything useful really. It's 2 basic dark pink cylinders, both with the exact same animation and one of them has a mono script which it says that doesn't exist. If I remove the gimbal, will it then work if I don't have this thrustTransform thing?

[OrbitusII]

As long as you do have an object to use as a thrustTransform, the engine can work. Make sure the blue (+Z) arrow is pointing the direction you want the thrust to go.

I'll take a look at the package in a little while, I've noticed that my packages want to export with a bunch of odd stuff so that may be affecting things a bit. Do you have the KSP Part Tools installed? Things won't work correctly unless you have those installed.

[Nicholander]

Yes, I do have KSP Part Tools. But could you answer my original question, if it does not gimbal, and does not have thrustTransform, will it work?

EDIT: Wait, so was I also pointing it wrongly in Unity?

Look at the way it's pointing and the 3D direction thing on the top right.

[OrbitusII]

No, you need a thrustTransform object. Without that the engine has no idea where to apply the force from and what direction to apply it in.

[Nicholander]

So how do I give it the thrustTranform then?
