Saves the current selection and load it later with a simple click.

// Simple example that lets you save the current selection and load it.

using UnityEngine; using UnityEditor; using System.Collections;

public class ExampleClass : EditorWindow { private int[] selectionIDs;

[MenuItem("Example/Selection Saver")] private static void Init() { ExampleClass window = (ExampleClass)GetWindow(typeof(ExampleClass)); window.Show(); }

void OnGUI() { if (GUILayout.Button("Save")) SaveSelection();

if (GUILayout.Button("Load")) LoadLastSavedSelection(); }

void OnSelectionChange() { selectionIDs = Selection.instanceIDs; }

private void SaveSelection() { var saveStr = "";

foreach (int i in selectionIDs) { saveStr += i.ToString() + ";"; }

saveStr = saveStr.TrimEnd(char.Parse(";")); EditorPrefs.SetString("SelectedIDs", saveStr); }

private void LoadLastSavedSelection() { string[] strIDs = EditorPrefs.GetString("SelectedIDs").Split(char.Parse(";"));

int[] ids = new int[strIDs.Length]; for (var i = 0; i < strIDs.Length; i++) ids[i] = int.Parse(strIDs[i]); Selection.instanceIDs = ids; } }
