前段时间在研究VGUI，所以也就找了点资料写了一个简单的HUD，提供给大家参考：
客户端项目中添加：hud_hello.cpp

//============Copyright ?2007-2008, RootCat, All rights reserved========================//

3// Purpose: 通过一个Hud显示当前玩家是飞行模式还是行走模式

36class CHudHello : public CHudElement, public vgui::Panel

53DECLARE_HUDELEMENT(CHudHello);

55//-----------------------------------------------------------------------------

58CHudHello::CHudHello( const char *pElementName ) : CHudElement( pElementName ), vgui::Panel( NULL, "HudHello" )
59{

61 scheme = vgui::scheme()->LoadSchemeFromFile("resource/ClientScheme.res", "ClientScheme");
62 SetScheme(scheme); // Here we load up our scheme and set this element to use it. Using a different scheme than ClientScheme doesn\\\\\\\\\'t work right off the bat anyways, so :)

103{

105 if ( !pPlayer )
106 return;
107 wchar_t *pText = L"行走模式";
108 surface()->DrawSetColor( 247, 148, 28, 255 );
109 surface()->DrawSetTextColor( 247, 148, 28, 255 );
110 if ( pPlayer->GetMoveType() == MOVETYPE_NOCLIP )
111

112 pText = L"飞行模式";
113 surface()->DrawSetColor( 255, 0, 0, 255 );
114 surface()->DrawSetTextColor( 255, 0, 0, 255 );

117 // get the right font handle for this scheme
118 vgui::IScheme *pScheme = vgui::scheme()->GetIScheme(GetScheme());
119 vgui::HFont hFont = pScheme->GetFont( "Default" );
120 surface()->DrawSetTextFont( hFont ); // set the font
121 surface()->DrawPrintText( pText, wcslen(pText) ); // print text这里是打印文字
122 surface()->DrawFilledRect( 10, 0,100 ,10 ); //x0,y0,x1,y1这里是绘制长方型
123 BaseClass::Paint();
124}
并修改scripts/HudLayout.res文件，添加以下代码：
1HudHello
2 {
3 "fieldName" "HudHello"
4 "visible" "1"
5 "enabled" "1"
6
7 "PaintBackgroundType" "2"
8
9 "text_xpos" "8"
10 "text_ypos" "20"
11 "digit_xpos" "50"
12 "digit_ypos" "2"
13 }
