Question by soham0243 · Jul 11, 2020 at 01:33 AM · rigidbodywheelcolliderboxcollider

Car collision problem for box collider and wheel collider

Hello, I am using Unity 2019.3.0f5. My car fails to collide with ground . It is the problem mentioned in the question below - Car falls through ground Wheel Collider My car hierarchy is the following - car_hierarchy I have attached a rigidbody to the car (parent), two box colliders to the Collider and transform and WheelCollider accordingly. Rigidbody - rigidbody Box Collider box_collider (Wheel Collider has default parameters) And a simple cs script attached the parent object.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Car : MonoBehaviour
 {
     public WheelCollider wheelColliderLeftFront;
     public WheelCollider wheelColliderRightFront;
     public WheelCollider wheelColliderLeftBack;
     public WheelCollider wheelColliderRightBack;
     
     public Transform wheelLeftFront;
     public Transform wheelRightFront;
     public Transform wheelLeftBack;
     public Transform wheelRightBack;
     
     public float maxMotorTorque = 100f;
     public float maxSteer = 20f;
     // Start is called before the first frame update
     //void Start()
     //{
         
     //}
 
     // Update is called once per frame
     void FixedUpdate()
     {
         wheelColliderLeftBack.motorTorque = Input.GetAxis("Vertical") * maxMotorTorque;
         wheelColliderRightBack.motorTorque = Input.GetAxis("Vertical") * maxMotorTorque;
         Debug.Log(Input.GetAxis("Vertical"));
     }
 }
 

Currently I only want my car to go forward without any turinig any direction. What's the possible way to resolve this issue ? Source: Youtube tutorial

Do the transform wheel objects have collider on it or Ridigbody on main collider? If yes, remove it.
