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