Find out if two children/gameObjects have the same parent.
I am trying to find out if two or more gameObjects within a list have the same parent by comparing them.
Example :
if(child1.transform.parent == child2.transform.parent)
{
/////do this
}
or
childList : List.<Transform> = new List.<Transform>();
currentObject : Transform; ///the current gameObject
if(childList[i].transform.parent == gameObject.transform.parent)//////the children in childList and the currentObject have the same parent
{
//////do this`enter code here`
}
Any help is greatly appreciated.
Here's some sample code to help push you in the right direction.
bool ShareSameParent (IEnumerable<Transform> childList)
{
foreach (var child1 in childList)
{
foreach (var child2 in childList)
{
if (child1 == child2)
continue;
if (child1.parent == child2.parent)
return true;
}
}
return false;
}
I haven't tested this code, and it's written in C#, but it should be very simple to convert to JavaScript.
Thanks for the reply but it wont work because it gives an error if I try to remove the child from the list.I have tried indexing the list with a for (i) but it still dosent let me pass to the next line.If I compare child1.parent to child2.parent or childList[i].parent to gameObject.parent it wont let me pass.
If I say : if(childList[i].transform.parent ==gameObject.transform.parent) { print("a"); } //considering that the children in the list and the gameObject have the same parent It wont print the line.
You cannot modify the content of a List while you are enumerating it. If you want to remove children from the List during enumeration, then try the following,
void ShareSameParent (List<Transform> childList)
{
var remove = new List<Transform>();
foreach (var child1 in childList)
{
foreach (var child2 in childList)
{
if (child1 == child2)
continue;
if (child1.parent == child2.parent)
{
// Add it to a list of children to removed later
remove.Add(child1);
continue;
}
}
}
// Remove the children from the List
foreach (var child in remove)
{
childList.Remove(child);
}
}
Thanks for the reply but I have already tested something similar by comparing child1.parent to child2.parent or child.parent to gameObject.parent but it never lets me pass to the next line.
If I say :
if(childList[i].transform.parent == gameObject.transform.parent)
{
print("a");
}
//considering that the children in the childList and the gameObject have the same parent
It wont print the line
