Question

Basically this:

gameObject.tag = "theTag";

On a prefab, needs to tag all the children in the prefab with that tag, without knowing their names specifically.

Is it possible?

Not tested, but this should work (C#):

foreach(Transform t in transform)
{
    t.gameObject.tag = "theTag";
}
gameObject.tag = "theTag";

Won't work on deep hierarchies- Transform[] only works on the layer directly below, it doesn't work recursively. Try using GetComponentsInChilderen<.Transform>() (without the . infront of the Transform (silly html tags having the same format as generics)) - this returns an array of all the transforms below the current transform.

Thanks, feel like I've learned something from this. Would be nice if layers and tags were components eh?

Here's the final JS:

for (var child : Transform in transform) { child.tag = "theTag"; }

I had the same issue and found it doesn't help when going past the first level of children. What I ended up doing was a recursive loop to solve the issue.

C# void OnDrawGizmosSelected () { ReTag(transform, transform.tag); }

void ReTag (Transform _transform, string tag) { foreach(Transform child in _transform){ child.gameObject.tag = tag; ReTag(child, tag); } }

Thought I would post for anyone else that might need it.

You can easily achieve that with a recursive method:

    AddTagRecursively (transform, "theTag");

void AddTagRecursively(Transform trans, string tag)
{
    trans.gameObject.tag = tag;
    if(trans.GetChildCount() > 0)
       foreach(Transform t in trans)
         AddTagRecursively(t, tag);
}

Thanks for this, I'll check if it works. My initial feeling is that you can't access grandchildren with GetComponents, because Unity throws an error as tags are not components...?

No, you use GetComponents, and then for each component returned use

component.gameObject.tag

to fix up the tag! No, tags are not components, but it is possible to access the tag of any object with just a reference to one component on that object.

Is there an easy way to apply the same tag to all children of an object?
