Wheel collider of Landing Gear Problems

[K.Yeon]

hi, im currently making a part pack contains landing gears, but right now the landing gears have two problems, I hope someone can help me with this!

First one, currently the wheel collider is parented under the "Gear" (retractable part) instead of the gear's suspension parent(the turning part), which is why the gear doesnt turn atm. But when i parent the WheelCollider Under the suspension parent, the whole turning part including the mesh would just 'float' upwards into the sky and goes through everything, it makes me laugh and cry at the same time :s i have no idea how to fix it ... have i done something wrong with hierarchy?

Second problem is how to make the breaks more efficiently? right now if i turn on the break with this gear on the ksc runway it would take about 10 times longer to break than the stock landing gear... And if i put on the break when the craft is going up hill terrain, sometime the velocity even increases!

these are the current values i use (for FSWheel module), below that is the hierarchy i used.

forwardsStiffness = 1

forwardsExtremumSlip = 1

forwardsExtremumValue = 5000

forwardsAsymptoteSlip = 2

forwardsAsymptoteValue = 2500

sidewaysStiffness = 1

sidewaysExtremumSlip = 1

sidewaysExtremumValue = 5000

sidewaysAsymptoteSlip = 2

sidewaysAsymptoteValue = 2500

wheelColliderRadius = 0.2

suspensionSpring = 85

suspensionDamper = 40

suspensionTargetPosition = -0.01

Thanks in advance!!

Did you go through the gear rigging thread in the dev links post?

Breaking force is changed with brakeTorque.

Can you post your config please?

The wheel collider should be child of the steering gameobject, not the part named as the suspension component, which I suspect is the case here. Its the most common error when setting up wheels. Watch my wheel modding YouTube tutorial for clarification, and there are a great many Unity tutorials which may help you understand the hierarchy too. Landing gear is a little different in the details, but not fundamentally so.

Thanks lo-fi and cpt.kipard, i got it to work finally xD i used captain's skylon nose gear development pages as a reference. the wheel tutorial was helpful too for setting the values
