Inspector Plugins

Introduction

Godot 3.1 comes with a new inspector. Adding plugins to it is now possible.

This tutorial will explain the process.

Inspector Plugin

This short tutorial will explain how to make a simple value editor. Create an EditorInspectorPlugin first. This is needed to initialize your plugin.

GDScript

  1. # MyEditorPlugin.gd
  3. extends EditorInspectorPlugin
  5. func can_handle(object):
  6.     # if only editing a specific type
  7.     # return object is TheTypeIWant
  8.     # if everything is supported
  9.     return true
  11. func parse_property(object,type,path,hint,hint_text,usage):
  12.     if (type==TYPE_INT):
  13.          add_custom_property_editor(path,MyEditor.new())
  14.          return true # I want this one
  15.     else:
  16.          return false

Editor

Here is an editor for editing integers

GDScript

  1. # MyEditor.gd
  2. class_name MyEditor
  4. var updating = false
  6. func _spin_changed(value):
  7.     if (updating):
  8.         return
  10.     emit_changed( get_property(), value )
  12. func update_property():
  13.     var new_value = get_edited_object()[ get_edited_property() ]
  15.     updating=true
  16.     spin.set_value( new_value )
  17.     updating=false
  19. var spin = EditorSpinSlider.new() # use the new spin slider
  20. func _init():
  21.    # if you want to put the editor below the label
  22.    #   set_bottom_editor( spin )
  23.    # else use:
  24.    add_child( spin )
  25.    # to remember focus when selected back
  26.    add_focusable( spin )
  27.    spin.set_min(0)
  28.    spin.set_max(1000)
  29.    spin.connect("value_changed",self,"_spin_changed")
