Game object custom properties


Hi, is it possible to create custom game object properties?
For example, would be great if I could set type of property and programmatically could fetch it.

For example, if I want to use game object instead of Gui node, but I want to be able to adjust alpha property in editor, not changing value programmatically.


#2 can be used to add custom properties to a game object. See the link below for more information.
