[HL] Flashlight indicator bug

[Matthaiks]

Save game with fully recharged and switched off flashlight, quit HL, launch HL, load that saved game and look at the flashlight indicator. It says depleted, but it's recharged if you activate it.

I can also confirm this on the Mac build

This happens because the server doesn't update the HUD on save game load.

To fix this UpdateClientData needs to send an update.

Add a member bool m_bRestored; to CBasePlayer.

Then before this code:

halflife/dlls/player.cpp

Line 3066 in c7240b9

return status;

Add this:

m_bRestored = true;

Then before this code:

halflife/dlls/player.cpp

Lines 4069 to 4097 in c7240b9

	// Update Flashlight
	if ((m_flFlashLightTime) && (m_flFlashLightTime <= gpGlobals->time))
	{
	if (FlashlightIsOn())
	{
	if (m_iFlashBattery)
	{
	m_flFlashLightTime = FLASH_DRAIN_TIME + gpGlobals->time;
	m_iFlashBattery--;
	if (!m_iFlashBattery)
	FlashlightTurnOff();
	}
	}
	else
	{
	if (m_iFlashBattery < 100)
	{
	m_flFlashLightTime = FLASH_CHARGE_TIME + gpGlobals->time;
	m_iFlashBattery++;
	}
	else
	m_flFlashLightTime = 0;
	}
	MESSAGE_BEGIN( MSG_ONE, gmsgFlashBattery, NULL, pev );
	WRITE_BYTE(m_iFlashBattery);
	MESSAGE_END();
	}

Add this:

if (m_bRestored)
{
	//Tell client the flashlight is on
	if (FlashlightIsOn())
	{
		MESSAGE_BEGIN(MSG_ONE, gmsgFlashlight, NULL, pev);
		WRITE_BYTE(1);
		WRITE_BYTE(m_iFlashBattery);
		MESSAGE_END();
	}
}

And before this code:

halflife/dlls/player.cpp

Line 4181 in c7240b9

}

Add this:

//Handled anything that needs resetting
m_bRestored = false;

On save game load the server will tell the client that the flashlight is on. This code is designed so any other data that needs resetting can be done inside an if (m_bRestored) check as well.

[SamVanheer]

This needs one more thing to work properly in all cases:

if (m_bRestored)
{
	//Always tell client about battery state
	MESSAGE_BEGIN(MSG_ONE, gmsgFlashBattery, NULL, pev);
	WRITE_BYTE(m_iFlashBattery);
	MESSAGE_END();

	//Tell client the flashlight is on
	if (FlashlightIsOn())
	{
		MESSAGE_BEGIN(MSG_ONE, gmsgFlashlight, NULL, pev);
		WRITE_BYTE(1);
		WRITE_BYTE(m_iFlashBattery);
		MESSAGE_END();
	}
}

Otherwise the battery value will be whatever it was before, zero if the game has just been launched.

25th Anniversary Update

Partially fixed, i.e. it displays as turned off instead of depleted:

This should be resolved in the October 2, 2024 Steam build.
