説明

ILayoutSelfController は所有する RectTransform を操る ILayoutController です。

The iLayoutSelfController derives from the base controller ILayoutController and controls the layout of a RectTransform.

Use the ILayoutSelfController to manipulate a GameObject’s own RectTransform component, which you attach in the Inspector. Use ILayoutGroup to manipulate RectTransforms belonging to the children of the GameObject.

Call ILayoutController.SetLayoutHorizontal to handle horizontal parts of the layout, and call ILayoutController.SetLayoutVertical to handle vertical parts. You can change the height, width, position and rotation of the RectTransform.

//This script shows how the GameObject’s own RectTransforms can be changed.
//This creates a rectangle on the screen of the scale, positition and rotation you define in the Inspector.
//Make sure to set the X and Y scale to be more than 0 to see it

using UnityEngine; using UnityEngine.UI; using UnityEngine.EventSystems;

public class Example : UIBehaviour, ILayoutSelfController { //Fields in the inspector used to manipulate the RectTransform public Vector3 m_Position; public Vector3 m_Rotation; public Vector2 m_Scale;

//This handles horizontal aspects of the layout (derived from ILayoutController) public virtual void SetLayoutHorizontal() { //Move and Rotate the RectTransform appropriately UpdateRectTransform(); }

//This handles vertical aspects of the layout public virtual void SetLayoutVertical() { //Move and Rotate the RectTransform appropriately UpdateRectTransform(); }

//This tells when there is a change in the inspector #if UNITY_EDITOR protected override void OnValidate() { Debug.Log("Validate"); //Update the RectTransform position, rotation and scale UpdateRectTransform(); }

#endif

//This tells when there has been a change to the RectTransform's settings in the inspector protected override void OnRectTransformDimensionsChange() { //Update the RectTransform position, rotation and scale UpdateRectTransform(); }

void UpdateRectTransform() { //Fetch the RectTransform from the GameObject RectTransform rectTransform = GetComponent<RectTransform>();

//Change the scale of the RectTransform using the fields in the inspector rectTransform.localScale = new Vector3(m_Scale.x, m_Scale.y, 0);

//Change the position and rotation of the RectTransform rectTransform.SetPositionAndRotation(m_Position, Quaternion.Euler(m_Rotation)); } }
