Sticky Notes

Fusion Industries prototyping Addons

This addon provides a ready to use sticky notes dispenser. A pen can be used to modify the sticky note texture, and each sticky note can be snapped to a magnetic surface.

The drawing itself is handled by the TextureDrawing addon, while the sticky aspect is dealed with the Magnets addon


StickyNoteDispenser is in charge to spawn a sticky note prefab when the user grab/ungrab the sticky note sample (uneditable) located on the dispenser. It is a subclass of the XRShared GrabbablePrefabSpawner class, that spawns an object when a reference grabbable is moved far enough.

It overrides the Awake() & ResetReferencePose() methods in to order to call the MoveStickyNote() function when a sticky note is spawned, to animate the reference grabbable after it returns to its default position, to give the impression a new post-it is printed.


StickyNoteColorSelection is in charge of synchronizing the sticky note background color. It is a subclass of the XRShared's GrabbableColorSelection class, that is a generic purpose color changing and synchronization class.

This class stores the color in the networked variable CurrentColor. The CheckColorModification() method is called during the FixedUpdateNetwork() to check if the local user used the joystick to change the sticky note color. In this case, ChangeColor() updates the networked variable CurrentColor. So, OnColorChanged() is called on all players thanks to the ChangeDetector. Then, the ApplyColorChange() override here updates the sticky note texture.

The default sticky note color will be the first of the colorList.

StickyNote prefab

In addition to the usual components required for a networked grabbable object, this prefab contains :

  • StickyNoteColorSelection to manage the sticky note color,
  • MagnetPoint from the Magnets addon to stick the note on a magnetic surface,
  • TextureDrawing & TextureSurface to manage the sticky note texture,
  • LayerSetter & Blocking surface on the DrawerContactzone object to set the layer and prevent the pencil from passing through the note

For a more complex prefab with a text layer, take a look at the Meeting sample.
