Use this class to implement custom editor tools. This is the base class from which all editor tools are inherited.
Use this class with EditorToolAttribute to register custom editor tools with the Editor.
using System; using UnityEngine; using UnityEditor; using UnityEditor.EditorTools;
// Tagging a class with the EditorTool attribute and no target type registers a global tool. Global tools are valid for any selection, and are accessible through the top left toolbar in the editor. [EditorTool("Platform Tool")] class PlatformTool : EditorTool { // Serialize this value to set a default value in the Inspector. [SerializeField] Texture2D m_ToolIcon;
GUIContent m_IconContent;
void OnEnable() { m_IconContent = new GUIContent() { image = m_ToolIcon, text = "Platform Tool", tooltip = "Platform Tool" }; }
public override GUIContent toolbarIcon { get { return m_IconContent; } }
// This is called for each window that your tool is active in. Put the functionality of your tool here. public override void OnToolGUI(EditorWindow window) { EditorGUI.BeginChangeCheck();
Vector3 position = Tools.handlePosition;
using (new Handles.DrawingScope(Color.green)) { position = Handles.Slider(position, Vector3.right); }
if (EditorGUI.EndChangeCheck()) { Vector3 delta = position - Tools.handlePosition;
Undo.RecordObjects(Selection.transforms, "Move Platform");
foreach (var transform in Selection.transforms) transform.position += delta; } } }
