| Parameter | Description |
|---|---|
| value | The target y coordinate for the bottom edge, in the parent's coordinate space. |
| preserveSize | When true (default), the element translates so the bottom edge reaches value while height is unchanged. When false, only the bottom edge moves: the top edge stays fixed and sizeDelta is adjusted to match the new height. |
Moves the bottom edge of this RectTransform to the specified position in its parent's coordinate space.
When preserveSize is true, adjusts anchoredPosition so that GetLocalBottom returns value; the element's size (sizeDelta) and top edge are not affected. When preserveSize is false, the top edge remains at its current position and the height is resized to reach value.
