public static float ScaleSlider (float scale, Vector3 position, Vector3 direction, Quaternion rotation, float size, float snap);

파라미터

scale The value the user can modify.
position The position of the handle in the space of Handles.matrix.
direction The direction of the handle in the space of Handles.matrix.
rotation The rotation of the handle in the space of Handles.matrix.
size The size of the handle in the space of Handles.matrix. Use HandleUtility.GetHandleSize if you want a constant screen-space size.
snap The snap increment. See Handles.SnapValue.

반환

float The new value modified by the user's interaction with the handle. If the user has not moved the handle, it will return the same value as you passed into the function.

설명

Make a directional scale slider.

This method will draw a 3D-draggable handle on the screen that looks like one axis on Unity's built-in scale tool. The handle will stretch and will scale a single float up and down.


Scale slider handle in the Scene View.

Add the following script to your Assets folder as ScaleSliderExample.cs and add the ScaleSliderExample component to an object in a scene.

using UnityEngine;

[ExecuteInEditMode] public class ScaleSliderExample : MonoBehaviour { public float scale { get { return m_Scale; } set { m_Scale = value; } } [SerializeField] private float m_Scale = 1f;

public virtual void Update() { transform.localScale = new Vector3(scale, 1f, 1f); } }

Add the following script to Assets/Editor as ScaleSliderExampleEditor.cs and select the object with the ScaleSliderExample component.

using UnityEditor;
using UnityEngine;

[CustomEditor(typeof(ScaleSliderExample)), CanEditMultipleObjects] public class ScaleSliderExampleEditor : Editor { public void OnSceneGUI() { ScaleSliderExample example = (ScaleSliderExample)target;

float size = HandleUtility.GetHandleSize(example.transform.position) * 1f; float snap = 0.5f;

EditorGUI.BeginChangeCheck(); float scale = Handles.ScaleSlider(example.scale, example.transform.position, example.transform.right, example.transform.rotation, size, snap); if (EditorGUI.EndChangeCheck()) { Undo.RecordObject(target, "Change Scale Value"); example.scale = scale; example.Update(); } } }
