new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

return_values

2 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.

Nullable Dictionary return pattern

For Dictionary returns, use empty dict to signal 'not found' and caller checks .is_empty(). Caller: var room: Dictionary = find_room(id); if room.is_empty(): return.

Nullable Object return pattern

For Object-typed returns like CharacterBody2D, use null to signal 'not found'. Example: if nodes.is_empty(): return null; return nodes[0].
