wheel problem

[Deltafee]

Hey I created two landing gears and this is the first time I created a wheel so I am not sure if I did this right. here is the picture of the wheel in unity and them in ksp.

As you can see the wheels are not working properly, in fact the only reason my capsule is up is because of the stock gears. Also this a static landing gear so there is no animation.

One problem is that your wheelCollider is sideways, the green line should be pointing downwards.

[Deltafee]

Okay I fixed that and it still doesn't work.

[EndlessWaves]

I had a closer look at the image and another problem if that you've got the wheel model and wheel collider on the same object. It won't work like that as the collider is designed to stay stationary and not rotate.

I can't see any other issues in that screenshot, can you post the config file?

Also, what errors does the game give you related to the part or the module you're using in the output_log.txt file in the KSP_data folder?

WheelColliders are disabled by default, so once they're the right way up any sinking to the ground is likely to be due to the module not loading far enough to enable them.

[Deltafee]

So the wheel collider is all by itself, just the size and location of the model? In my model there are two wheels, so should there be two different wheel colliders? Ill try that tommorrow!

this might help:

Given he's using the name suspensionParent and referred to the part as a landing gear I inferred two things:

1) He's using the landing gear module not the rover wheel one

2) He's already checked the stickies and seen the picture of the stock landing gear setup, hence his use of the suspensionParent name.

@Deltafee:

It doesn't have to be by itself but it does need to be on a separate object to the wheel model (that isn't a child of the wheel model). You need to position it at the suspension's point of maximum compression.

I don't know if the default wheel position matters for the landing gear module or if it snaps it to the centre of the wheelCollider but to be on the safe side I would put them in the same location.

[Deltafee]

Yeah I am using the stock part diagram, I have the wheel Colliders separate but in the same directory as the wheel models, I am alittle lost on what you mean by the "suspension's point of maximum compression". Here is a picture of what I have done:

here is the stock diagram i am following as well:

They still appear to be the wrong way round, I can't see the line on the WheelCollider in that picture so I assume it's pointing off to the side as it was in the previous screenshot. You don't need the mesh filter on the WheelColliders.

On the suspension, I just mean that if the wheels go up and down then they should start out as far up as possible.

I thought you said the green arrow should be pointing down?

[Devo]

Line, not arrow.

[EndlessWaves]

I thought you said the green arrow should be pointing down?

The WheelCollider representation is a green circle with a line from the centre to a point on the circumference, that line needs to be vertical and touching the ground.

[Deltafee]

Okay so as of now it is vertical in the x-y plane from what I am understanding it needs to be vertical in the y-z plane?

so like this?

With the circle of the wheel collider being head on in that picture I can't see where the down indicator line on them is.

sorry about being absent, I had to deal with finals for three weeks. Here's the new picture:

[EndlessWaves]

The line circled in red is the one I'm talking about, that has to be at the bottom of the wheel:

[Deltafee]

OH I didn't even see that! So yeah that fixed it, I'll post a picture of the completed project tomorrow thanks everyone!!!

Update

[Deltafee]

So here's the finished version of my landing gear:

Unfortunately there's a new problem which is how do I make it so the wheels brake?

It should be automatic, if it's not working try adding wheelName = WheelCollider to the ModuleLandingGear section of the config.

[Deltafee]

So after updating to v0.20 and now my landing gear isn't working, here's what I did:

I'm not really sure what I am doing wrong.

[EndlessWaves]

0.20 of the game or 0.20 of the part tools?

[sirkut]

Judging from what the Part Tools section on the right looks like I would venture it's .20 Part tools. (I haven't switched yet, just finally figured out making wheels)

[Deltafee]

Both ksp 0.20 nad parttools.

[EndlessWaves]

Both ksp 0.20 nad parttools.

At the same time? That makes troubleshooting harder. What error are you getting in the debug console/output log?

[Deltafee]

The debug says

NullReferenceException: Object reference not set to an instance of an object

Here's a picture of what it looks like in parttools:
