IMGUI之GUI组件学习

废话少说，这是学习教程写下的笔记
对应学习的教程地址

Rect的使用及其的参数说明

Rect mRect = new Rect(0, 60, 200, 20);

四个参数分别为x、y、width、height，(x,y)就是位置，基于左上角的锚点，width和height就是宽和高，这四个参数能表达出控件的位置和大小。

Label 文本标签

Rect mRect = new Rect(0, 60, 200, 20);

void OnGUI()
{
	GUI.Label(mRect, "文本");
}

TextField 文本输入框

Rect mRect = new Rect(0, 60, 200, 20);
string mTextValue = "";

void OnGUI()
{
    mTextValue = GUI.TextField(mRect, mTextValue);
}

TextArea 文本输入区

Rect mRect = new Rect(0, 60, 200, 80);
string mTextValue = "";

void OnGUI()
{
    mTextValue = GUI.TextArea(mRect, mTextValue);
}

PasswordField 密码框

Rect mRect = new Rect(0, 60, 200, 20);
string mPasswordValue = "";
void OnGUI()
{
    mPasswordValue = GUI.PasswordField(mRect, mPasswordValue, '*');
}

Button 按钮（RepeatButton不写了）

void OnGUI()
{
    if (GUI.Button(mRect, "这是一个按钮"))
    {
        Debug.Log("这里是按下之后要做的事");
    }
}

Toggle 勾选项

bool mBoolValue = false;
void OnGUI()
{
    mBoolValue = GUI.Toggle(mRect, mBoolValue,"点击勾选我");
}

Toolbar工具栏

Rect mRect = new Rect(0, 60, 200, 20);
int mToolBarIndex = 0;
void OnGUI()
{
    mToolBarIndex = 
        GUI.Toolbar(mRect,
                    mToolBarIndex, 
                    new[] { "选项1", "选项2", "选项3", "选项4" });
}

Box框

Rect mRect = new Rect(0, 60, 200, 20);
void OnGUI()
{
    GUI.Box(mRect, "这是一个Box框");
}

ScrollView 滚动视图

Vector2 scrollPosition; //滚动到的位置
Rect mScrollRect = new Rect(0, 0, 200, 100); //在屏幕中显示的大小
Rect mViewRect = new Rect(0, 0, 200, 300); //包含内容的大小
Rect mTextRect = new Rect(0, 20, 200, 100);
Rect mBoxRect = new Rect(0, 0, 200, 300);

void OnGUI()
{
    scrollPosition = GUI.BeginScrollView(mScrollRect, scrollPosition, mViewRect);
    GUI.TextArea(mText
                 Rect, "测试用的Text框，不返回值");
    GUI.Box(mBoxRect, "这是一个Box框");
    GUI.EndScrollView();
}

参数看备注……第一个参数和第三个参数不要写反了

Slider拖动条

Rect mHorizontalSliderRect = new Rect(0, 0, 200, 300);
Rect mVerticalSliderRect = new Rect(30, 100, 200, 300);
float mLeftValue = 0; //左边的数值
float mRightValue = 1f; //右边的数组
float mSliderValue = 0; //拖动条的数值
void OnGUI()
{
    mSliderValue = GUI.HorizontalSlider(mHorizontalSliderRect, mSliderValue, mLeftValue, mRightValue);
    mSliderValue = GUI.VerticalSlider(mVerticalSliderRect, mSliderValue, mRightValue, mLeftValue);
}

拖动条分为水平和垂直，需要有一个变量保存拖动条的值。

Group 组

Rect mGrouprect = new Rect(0, 0, 200, 300);
Rect mTextRect = new Rect(0, 100, 200, 100);
Rect mBoxRect = new Rect(0, 50, 200, 100);

void OnGUI()
{
    GUI.BeginGroup(mGrouprect,"这是一个组");
    GUI.TextArea(mTextRect, "测试用的Text框，不返回值");
    GUI.Box(mBoxRect, "这是一个Box框");
    GUI.EndGroup();
}
