Overview

The RescalePanel control allows users to rescale a parent panel by dragging a handle. Unlike ResizePanel, this control modifies the parent’s local scale rather than its size delta, and automatically adjusts the handle’s size delta to maintain visual consistency during scaling.

Properties

The properties of the RescalePanel control are as follows:

Property Description
Min Size Minimum scale constraint for the panel (Vector2). Defines the minimum local scale values for X and Y axes
Max Size Maximum scale constraint for the panel (Vector2). Defines the maximum local scale values for X and Y axes

Methods

The RescalePanel control implements Unity’s IPointerDownHandler and IDragHandler interfaces but does not expose additional public methods.

Method Arguments Description
OnPointerDown PointerEventData Handles pointer down events to bring panel to front and record starting position
OnDrag PointerEventData Handles drag events to rescale the parent panel by adjusting local scale and compensating handle size

Usage

To use the RescalePanel control:

  1. Add the component via “Add Component -> UI -> Extensions -> RescalePanels -> RescalePanel”
  2. Attach the component to a child GameObject of the panel you want to rescale
  3. The parent Transform will be automatically detected and become rescalable via local scale
  4. Configure min/max size constraints in the inspector to limit scaling range

Example code for setting scale constraints:

var rescalePanel = rescaleHandle.GetComponent<RescalePanel>();
rescalePanel.minSize = new Vector2(0.5f, 0.5f);  // Minimum 50% scale
rescalePanel.maxSize = new Vector2(3.0f, 3.0f);  // Maximum 300% scale
