position | 屏幕上用于滚动条的矩形。 |
value | 最小值和最大值之间的位置。 |
size | 我们能看到多少内容? |
leftValue | 滚动条左端的值。 |
rightValue | 滚动条右端的值。 |
style | 用于滚动条背景的样式。如果省略,则使用当前 GUISkin 的 horizontalScrollbar 样式。 |
float 修改后的值。用户可以通过拖动滚动条或单击末端的箭头来更改该值。
创建一个水平滚动条。滚动条是用于滚动文档的控件。大多数情况下,您需要的可能是滚动视图。
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { public float hSbarValue;
void OnGUI() { hSbarValue = GUI.HorizontalScrollbar(new Rect(25, 25, 100, 30), hSbarValue, 1.0F, 0.0F, 10.0F); } }
搜寻额外的元素:
系统按以下方式在当前皮肤中搜寻滚动条的样式:1) 对于滚动条末端的按钮,向样式名称添加“leftbutton”和“rightbutton”;
2) 对于滚动条滑块(鼠标拖动的条),向样式名称添加“thumb”。
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { public float scrollPos = 0.5f;
// This will use the following style names to determine the size / placement of the buttons // MyScrollbarleftbutton - Name of style used for the left button. // MyScrollbarrightbutton - Name of style used for the right button. // MyScrollbarthumb - Name of style used for the draggable thumb. void OnGUI() { scrollPos = GUI.HorizontalScrollbar(new Rect(0, 0, 100, 20), scrollPos, 1.0f, 0.0f, 100.0f, "Scroll"); } }
