unity3d - Unity - 设置 GUI.Box 背景颜色

Question

我正在尝试设置 GUI.Box 的背景颜色:

void OnGUI()
        {
            string LatLong;
           LatLong = map.calc.prettyCurrentLatLon;
            var mousePosition = Input.mousePosition;
            float x = mousePosition.x + 10;
            float y = Screen.height - mousePosition.y + 10;
            GUI.backgroundColor = Color.red;
            GUI.Box(new Rect(x, y, 200, 200), LatLong);
        }

但是，该框显示为半透明的黑色，而白色文本是柔和的，而不是不透明的白色。

你必须使用 s gui 样式:

private GUIStyle currentStyle = null;
 
void OnGUI()
{  
    InitStyles();
    GUI.Box( new Rect( 0, 0, 100, 100 ), "Hello", currentStyle );
}
 
private void InitStyles()
{
    if( currentStyle == null )
    {
        currentStyle = new GUIStyle( GUI.skin.box );
        currentStyle.normal.background = MakeTex( 2, 2, new Color( 0f, 1f, 0f, 0.5f ) );
    }
}
 
private Texture2D MakeTex( int width, int height, Color col )
{
    Color[] pix = new Color[width * height];
    for( int i = 0; i < pix.Length; ++i )
    {
        pix[ i ] = col;
    }
    Texture2D result = new Texture2D( width, height );
    result.SetPixels( pix );
    result.Apply();
    return result;
}
