|
-- Blocker consume input if `gui.pick_node` works on it.
|
|
--
|
|
-- • Blocker inheritance @{BaseComponent}, you can use all of its methods in addition to those described here.
|
|
--
|
|
-- • Blocker initial enabled state is `gui.is_enabled(node, true)`
|
|
--
|
|
-- • The Blocker node should be enabled to capture the input
