Static typing
In the use case above : is used to declare a variable’s type.
For classes and buitl-in types this exposes their members for use
e.g target._all_members_of_CollisionObject2D
Additionally you can use this with function arguments to force that type as a requirement so any thing that’s not of the type trows an error.
e.g func get_target(targetBody : CollisionObject2D):
Side Note: This actually mandatory in the family of C languages for function and variables and in other use cases is known as Type Casting
What i wrote before was off the top of my head and it took me a while but was able to find the official documentation
