 * Notes
+
+** removing connected nodes
+- nodes that are connected must be disconnected before deletion
+- otherwise strange things happen
+
+** Timing
+- add a child node
+- search for Timer
+
+*** properties
+- autostart: whether it starts as soon as scene is ready in tree
+- one shot: time once and stop
+- wait time: the actual time it goes
+
+*** signals
+- timeout
+  - got to Inspector->Node
+  - timeout emits a signal when the wait time hits zero
+
+** Spawning Gems
+
+Put the following in the script that you want to create nodes in based on a scene:
+
+#+BEGIN_SRC gdscript
+@export var gem_scene: PackedScene
+#+END_SRC
+
+*** terms
+- =@export=
+  - makes the variable accessible and modifiable from the Godot editor
+  - allows assigning variables through the interface
+
+    #+ATTR_HTML: :width 300px
+    [[file:../../../_share/media/albert/img/section03/S03_L15_EX01.png]]
+
+- =PackedScene=
+  - resource that holds a scene in a packed, ready to load state
+
+*** what it does
+allows us to create instances of the scene
+
+- drag a scene into the property in the inspector
+- call instance
+
+#+BEGIN_SRC gdscript
+func spawn_gem() -> void:
+	var gem_instance = gem_scene.instance()
+	add_child(gem_instance)
+#+END_SRC
+
+** how to explicitly assign the type of a custom script
+- in the script near the top type in
+  #+BEGIN_SRC gdscript
+  class_name CustomName
+  #+END_SRC
+
+- then override on assigning the value
+  #+BEGIN_SRC gdscript
+  var new_gem: CustomName = gem_scene.instantiate()
+  #+END_SRC
