Function: resolveCanvasGroupState()
resolveCanvasGroupState(
world,entity):CanvasGroupState
Defined in: ui/utilities/resolve-canvas-group-state.ts:45
Walks entity's ParentEcsComponent chain (starting at entity itself)
combining every CanvasGroupEcsComponent found along the way: alpha
multiplies, interactable/blocksRaycasts AND together. The walk stops
after including a group whose ignoreParentGroups is true - that
group's own values still apply, but nothing further up the chain does.
Used by createUiCanvasGroupEcsSystem (alpha) and by
createUiRaycastEcsSystem/createUiInteractionEcsSystem/
createUiNavigationEcsSystem (interactable/blocksRaycasts) so a group's
effect reaches every descendant without mutating each one's own
UiInteractableEcsComponent/SpriteEcsComponent/TextEcsComponent
fields - only the generic opacityMultiplier fields are ever written,
leaving each element's own authored tint/interactable/blocksRaycasts
untouched underneath.
Parameters
world
The ECS world entity belongs to.
entity
number
The entity to resolve the combined canvas group state for.
Returns
The combined alpha/interactable/blocksRaycasts, { alpha: 1, interactable: true, blocksRaycasts: true } if no CanvasGroupEcsComponent governs entity at all.
