切换到手册
public static Vector2 BeginScrollView (Vector2 scrollPosition, params GUILayoutOption[] options);
public static Vector2 BeginScrollView (Vector2 scrollPosition, bool alwaysShowHorizontal, bool alwaysShowVertical, params GUILayoutOption[] options);
public static Vector2 BeginScrollView (Vector2 scrollPosition, GUIStyle horizontalScrollbar, GUIStyle verticalScrollbar, params GUILayoutOption[] options);
public static Vector2 BeginScrollView (Vector2 scrollPosition, GUIStyle style);
public static Vector2 BeginScrollView (Vector2 scrollPosition, GUIStyle style, params GUILayoutOption[] options);
public static Vector2 BeginScrollView (Vector2 scrollPosition, bool alwaysShowHorizontal, bool alwaysShowVertical, GUIStyle horizontalScrollbar, GUIStyle verticalScrollbar, params GUILayoutOption[] options);
public static Vector2 BeginScrollView (Vector2 scrollPosition, bool alwaysShowHorizontal, bool alwaysShowVertical, GUIStyle horizontalScrollbar, GUIStyle verticalScrollbar, GUIStyle background, params GUILayoutOption[] options);

参数

scrollPosition 用于显示的位置。
alwayShowHorizontal 可选参数,指示始终显示水平滚动条。如果为 false 或省略,则仅在滚动视图中的内容比滚动视图本身更宽时才显示。
alwayShowVertical 可选参数,指示始终显示垂直滚动条。如果为 false 或省略,则仅在滚动视图中的内容比滚动视图本身更高时才显示。
horizontalScrollbar (可选)用于水平滚动条的 GUIStyle。如果省略,则使用当前 GUISkinhorizontalScrollbar 样式。
verticalScrollbar (可选)用于垂直滚动条的 GUIStyle。如果省略,则使用当前 GUISkinverticalScrollbar 样式。

返回

Vector2 修改后的 scrollPosition。将其反馈到您传入的变量中,如示例所示。

描述

开始一个自动布局的滚动视图。

自动布局滚动视图将接受您放入其中的任何内容并正常显示。如果大小不适合,将显示滚动条。BeginScrollView 调用必须始终与 EndScrollView 调用配对使用。

\ 游戏视图中的滚动视图。

using UnityEngine;

public class ExampleScript : MonoBehaviour { // The variable to control where the scrollview 'looks' into its child elements. Vector2 scrollPosition;

// The string to display inside the scrollview. 2 buttons below add & clear this string. string longString = "This is a long-ish string";

void OnGUI() { // Begin a scroll view. All rects are calculated automatically - // it will use up any available screen space and make sure contents flow correctly. // This is kept small with the last two parameters to force scrollbars to appear. scrollPosition = GUILayout.BeginScrollView( scrollPosition, GUILayout.Width(100), GUILayout.Height(100));

// We just add a single label to go inside the scroll view. Note how the // scrollbars will work correctly with wordwrap. GUILayout.Label(longString);

// Add a button to clear the string. This is inside the scroll area, so it // will be scrolled as well. Note how the button becomes narrower to make room // for the vertical scrollbar if (GUILayout.Button("Clear")) longString = "";

// End the scrollview we began above. GUILayout.EndScrollView();

// Now we add a button outside the scrollview - this will be shown below // the scrolling area. if (GUILayout.Button("Add More Text")) longString += "\nHere is another line"; } }
