Question about Types (B3D)

If you want a function to return a handle to an object (custom type), do this:

Function FindBuilding.building(id)
	For b.building = Each building
		If b\id = id Then Return b
	Next
End Function

; Find the building with id = 5
ABuilding.Building = FindBuilding(5)

The ".building" at the end of the function name states that the function will be returning a pointer (= handle) to a building-instance.

It's the same as having a function that would return a string:

Function GetFirstChar$(aString$)
	Local b$ = Mid$(aString$, 1, 1)

	Return b$
End Function

Here the "$" states that the function will be returning a string.



This works, but you didn't create a house-instance yet.
The line "Global hse.house" just creates a global variable that is able to hold a handle to a house-instance, but the variable is still empty.
To create one, use this:

Global hse.house = New house
