add prefix to children names in unity

Questions & Answers
1

I need to rename the bones of many characters because from where I bought the models and animations they rename the bones to prevent people from using the same animations from character to character, why would I have the same animation 30 times when I could have just one animation for all character. So I wanna rename the bones of all characters so I can have the same animations on all characters, could someone help me create a script to do this automatically? I know C# but I have never done anything like this (editor scripting) and bones are to many to rename them manually. What I need to do is add a Prefix to the bones names, I already tested it by doing it manually and it works perfectly.

Thanks in advance.

// Drop this in Assets/Editor, and you will get a new menu item.
// Change the prefix to what you want.
// Backup your project.
// Use menu item to apply changes.

using UnityEngine;
using UnityEditor;

static class PrefixSelectionChildren 
{
	const string prefix = "PREFIX_"; // Change to whatever you want to prefix with

	[MenuItem("Answers/Apply Prefix to Children")]
	public static void ApplyPrefix()
	{
		if (!EditorUtility.DisplayDialog("Child Prefix Warning", 
            "You are about to rename children of your current selection. Undo is not possible.

Are you sure you want to continue?",
“Yes, I understand the risk”,
“No, I changed my mind”))
return;

		GameObject[] gos = Selection.gameObjects;
		foreach (GameObject go in gos) 
		{
			var children = go.GetComponentsInChildren(typeof(Transform));
			foreach (Transform child in children) 
			{
				// Don't apply to root object.
				if (child == go.transform)
					continue;
				
				child.name = prefix + child.name;
			}
		}
	}
