Function: createUiTooltipEcsSystem()
createUiTooltipEcsSystem(
time):EcsSystem<[TooltipEcsComponent,UiInteractableEcsComponent]>
Defined in: ui/systems/ui-tooltip-system.ts:62
Creates a system that shows/hides a TooltipEcsComponent's panel/
label (toggling SpriteEcsComponent.enabled/TextEcsComponent.enabled,
the same mechanism createDropdown uses to hide its closed option list)
based on the source entity's own UiInteractableEcsComponent state:
visible while deriveUiInteractionVisualState reads hover or pressed
(pointer-hovered, gamepad/keyboard-focused, or mid-press - source-agnostic,
like the rest of this module) and that state has held continuously for
at least showDelayMilliseconds; hidden immediately otherwise.
Positioning is deliberately not this system's job - createTooltip
parents the tooltip to the source entity with an ordinary anchored
RectTransformEcsComponent, so createUiLayoutEcsSystem resolves its
position every frame exactly like any other UI child, following the
source (and reflecting layout changes to it) with no extra code here.
Must be registered after createUiInteractionEcsSystem and
createUiNavigationEcsSystem (it reads the interaction state they
write) and before createRenderEcsSystem.
Parameters
time
The time instance driving hoverElapsedMilliseconds.
Returns
EcsSystem<[TooltipEcsComponent, UiInteractableEcsComponent]>
The UI tooltip ECS system.
