Es/VGUI Health bar

Resumen

Este tutorial te enseñará como integrar una Barra VGUI(en) Health(en). Esto es un copia pega del tutorial del SDL del 2013

Código

Primero crea los archivos hud_healthbar.cpp y hud_healthbar.h en tu cliente preferido, luego pega el siguiente código:

hudhealthbar.cpp

#include "cbase.h" 
#include "hud.h" 
#include "hud_macros.h" 
#include "c_baseplayer.h" 
#include "hudhealthbar.h" 
#include "iclientmode.h" 
#include "vgui/ISurface.h"

using namespace vgui;

#include "tier0/memdbgon.h" 

DECLARE_HUDELEMENT (CHudHealthbar);

# define HULL_INIT 80 

//------------------------------------------------------------------------
// Purpose: Constructor
//------------------------------------------------------------------------

CHudHealthbar:: CHudHealthbar (const char * pElementName) : 
	CHudElement (pElementName), BaseClass (NULL, "HudHealthbar")
{
	vgui:: Panel * pParent = g_pClientMode-> GetViewport ();
	SetParent (pParent);

	SetHiddenBits (HIDEHUD_HEALTH | HIDEHUD_PLAYERDEAD | HIDEHUD_NEEDSUIT);
}

//------------------------------------------------------------------------
// Purpose:
//------------------------------------------------------------------------

void CHudHealthbar:: Init()
{
	Reset();
}

//------------------------------------------------------------------------
// Purpose:
//-----------------------------------------------------------------------

void CHudHealthbar:: Reset (void)
{
	m_flHull = HULL_INIT;
	m_nHullLow = -1;
	SetBgColor (Color (0,0,0,128));
}


//------------------------------------------------------------------------
// Purpose:
//------------------------------------------------------------------------

void CHudHealthbar:: OnThink (void)
{
	float newHull = 0;
	C_BasePlayer * local = C_BasePlayer:: GetLocalPlayer ();

	if (!local)
		return;

	// Never below zero 
	newHull = max(local->GetHealth(), 0);

	// DevMsg("Sheild at is at: %f\n",newShield);
	// Only update the fade if we've changed health
	if (newHull == m_flHull)
		return;

	m_flHull = newHull;
}


//------------------------------------------------------------------------
// Purpose: draws the power bar
//------------------------------------------------------------------------

void CHudHealthbar::Paint()
{
	// Get bar chunks

	int chunkCount = m_flBarWidth / (m_flBarChunkWidth + m_flBarChunkGap);
	int enabledChunks = (int)((float)chunkCount * (m_flHull / 100.0f) + 0.5f );

	// Draw the suit power bar
	surface()->DrawSetColor (m_HullColor);

	int xpos = m_flBarInsetX, ypos = m_flBarInsetY;

	for (int i = 0; i < enabledChunks; i++)
	{
		surface()->DrawFilledRect(xpos, ypos, xpos + m_flBarChunkWidth, ypos + m_flBarHeight);
		xpos += (m_flBarChunkWidth + m_flBarChunkGap);
	}

	// Draw the exhausted portion of the bar.
	surface()->DrawSetColor(Color(m_HullColor [0], m_HullColor [1], m_HullColor [2], m_iHullDisabledAlpha));

	for (int i = enabledChunks; i < chunkCount; i++)
	{
		surface()->DrawFilledRect(xpos, ypos, xpos + m_flBarChunkWidth, ypos + m_flBarHeight);
		xpos += (m_flBarChunkWidth + m_flBarChunkGap);
	}

	// Draw our name

	surface()->DrawSetTextFont(m_hTextFont);
	surface()->DrawSetTextColor(m_HullColor);
	surface()->DrawSetTextPos(text_xpos, text_ypos);

	//wchar_t *tempString = vgui::localize()->Find("#Valve_Hud_AUX_POWER");

	surface()->DrawPrintText(L"HULL", wcslen(L"HULL"));
}

HudLayout.res

Ahora añade este otro código al archivo HudLayout.res en la carpeta scripts , localizada en el directorio mod, y abajo del todo añade el siguiente código:

    HudHealthbar
    {

    "fieldName" "CHudHealthBar"
    "visible" "1"
    "enabled" "1"
    "xpos" "12"
    "ypos" "420"
    "wide" "120"
    "tall" "10"
    "text_xpos" "5"
    "text_ypos" "2"
    "TextColor" "0 255 0 80"
    "PaintBackgroundType" "2"

    }
