Function: resolveRect()
resolveRect(
parentRect,rectTransform,pixelsPerUnit?):Rect
Defined in: ui/utilities/resolve-rect.ts:64
Resolves a RectTransformEcsComponent's rect against its parent's
already-resolved rect. Pure - takes no EcsWorld/entity, reads no other
state - so the entire anchor/pivot/stretch surface is unit-testable in
isolation.
x and y are resolved independently by resolveAxis, since each
is its own UiPointAxis (literal size, moves with the anchor) or
UiStretchAxis (resizes with the parent, margin added to the anchored
span) - a mixed anchor (e.g. UiAnchor.stretchTop, stretched
horizontally but point-anchored vertically) simply resolves each axis
under its own rule.
Parameters
parentRect
The parent's already-resolved rect, in UI world space.
rectTransform
The rect transform to resolve.
pixelsPerUnit?
number = 1
The owning canvas's live reference-pixel-to-screen-pixel
ratio (see calculatePixelsPerUnit), used to convert a 'screenPixels'-unit
size/margin (see UiAxisSizeUnit) into reference pixels. Defaults
to 1 - a neutral value under which 'screenPixels' behaves exactly like
'referencePixels' - for callers that don't track a live ratio.
Returns
The resolved rect, in the same UI world space as parentRect.
