now what i am try to do is to create AI for enemy car in my racing game for that i have to create a path first so in order to do that i have written this script in which i am try to access child nodes of parent so for that i have created array and in which it is giving me error Transform pathTranform = GetComponentInChildren();
error is

Cannot implicitly convert type UnityEngine.Transform to UnityEngine.Transform

i am using this tutorial for path making Car AI Tutorial #1 (Unity 5 ) - Make the Path - YouTube
please help me out

thanks in advance

    using UnityEngine;
    using System.Collections;
    using System.Collections.Generic;  

    public class path : MonoBehaviour {

public Color lineColor;

private List<Transform> nodes = new List<Transform>();

void OnDrawGizmos()
{
    Gizmos.color = lineColor;
    Transform[] pathTranform = GetComponentInChildren<Transform>();    // here is the error
    nodes = new List<Transform>();

    for(int i = 1; i < pathTranform.Length; i++)
    {
        if(pathTranform[1] != transform)
        {
            nodes.Add(pathTranform*);*

}
}
for(int i = 0; i < nodes.Count; i++)
{
Vector3 CurrentNode = nodes*.position;*
Vector3 previousNode = Vector3.zero;
if(i > 0)
{
previousNode = nodes[i - 1].position;
}
else if(i == 0 && nodes.Count > 1)
{
previousNode = nodes[nodes.Count - 1].position;
}
Gizmos.DrawLine(previousNode, CurrentNode);
}
}

}

If you want to access components in children, plural, then you need to use GetComponentsInChildren.

Transform[] pathTranform = GetComponentsInChildren<Transform>();
