Inner classes

Learn Inner classes in GDScript with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.

10 min read • Beginner

Inner classes is an atomic GDScript topic inside Classes & Scripts. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what Inner classes changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.

Topic-specific example

gdscript-03-03-inner-classes.gd
gdscript Try It Live 
class InventoryItem:
    var name: String
    func _init(n: String): name = n
Edge case / engineering note

Pay attention to the contract exposed by the type, which members belong to instances versus the type itself, and what dispatch occurs at runtime.
