Aux Power Drain

[Carbonis]

Hi,

As I have limited C++ knoledge, I was wondering if anyone here could help me. I have a screenoverlay which will eventually be a nightvision feature in game. However, I do not know how to drain the aux power when the overlay is on and to turn it off when the power is drained.

Any suggestions? Thanks in advance

This is checks if there is enough power.

if ( m_HL2Local.m_flSuitPower <= 0.0f )
{
if( IsSprinting() )
{
StopSprinting();
}
}

[Carbonis]

Thanks. Now, if I knew the code to drain power...

[longshanksAOC]

pOwner->SuitPower_Drain(20.0f);

[Carbonis]

Thank you very much!

[Carbonis]

Hmm, sorry to bother everyone again, but I still have problems with the code provided.

Current solution snippet involving the screenoverlay:

if( bDisplayed )
{
// turn it off
view->SetScreenOverlayMaterial( NULL );
cvar->FindVar("mat_fullbright")->SetValue(0);
}
else
{
// turn it on
view->SetScreenOverlayMaterial( pMaterial );
pHLPlayer->SuitPower_Drain(20.0f);
cvar->FindVar("mat_fullbright")->SetValue(1);
}

Any help please on where I am going wrong?

Thanks

you need a bool IsDisplayed then set it something like this
if( bDisplayed )
{
// turn it off
view->SetScreenOverlayMaterial( NULL );
cvar->FindVar("mat_fullbright")->SetValue(0);
IsDisplayed = false;
}
else
{
// turn it on
view->SetScreenOverlayMaterial( pMaterial );
cvar->FindVar("mat_fullbright")->SetValue(1);
IsDisplayed = true;
}

and below it

if ( IsDisplayed == true )
{
pHLPlayer->SuitPower_Drain(20.0f);
}

so now it drains if its enabled and not when its toggled on.

[Carbonis]

I did have a bool, just not shown in quote, nevertheless I thank you for the help with the power drain implementation.

[Carbonis]

One final request, I keep on getting two main errors when compiling (I got rid of 5!)

Could somebody help me correct the solution so the errors do not occur?

1>.\view_scene.cpp(4742) : error C2065: 'pHLPlayer' : undeclared identifier
1>.\view_scene.cpp(4742) : error C2227: left of '->SuitPower_Drain' must point to class/struct/union/generic type
1> type is ''unknown-type''

Current, and hopefully penultimate solution!
//NightVision
static void ScreenOver_f( void )
{
IMaterial *pMaterial = materials->FindMaterial( "HUDoverlays/nightvision", TEXTURE_GROUP_OTHER, true );

{
static bool bDisplayed;
bool IsDisplayed;


if( bDisplayed )
{
view->SetScreenOverlayMaterial( NULL );
cvar->FindVar("mat_fullbright")->SetValue(0);

IsDisplayed = false;
}
else
{
view->SetScreenOverlayMaterial( pMaterial );
cvar->FindVar("mat_fullbright")->SetValue(1);
IsDisplayed = true;
}

bDisplayed = !bDisplayed;

if( IsDisplayed = true )
{
pHLPlayer->SuitPower_Drain( 30 );
}

}
}
static ConCommand r_screenover( "r_screenover", ScreenOver_f );

Thanks to everyone for their help so far!

[razvan252]

try this

CBasePlayer *pPlayer = ToBasePlayer( GetOwner() );
pPlayer->SuitPower_Drain( 30 );

[Carbonis]

One final request now, as I know what to do except one thing. At the beginning of the file all the headers to be included are shown, right? How would I include one from the client side, as the view_scene.cpp file is in the server side?

Thanks

[Carbonis]

Please? Anyone?

[Lolmen]

You can't use client side headers on server side.

[razvan252]

what do you need to include?

[Carbonis]

The nightvision instructions are in view_scene.cpp (client side, source files, HL2 DLL), the code which is for the suit's power interface is in the header HL2_Player.h (Server side, Source files, HL2 DLL).

[Carbonis]

One final error which I would like assistance with:


1>.\view_scene.cpp(4751) : error C2065: 'player' : undeclared identifier

view_scene.cpp

Additional includes:

#if defined( CLIENT_DLL )
#define CHL2_Player C_BaseHLPlayer
#include "c_basehlplayer.h"
#else
#include "hl2_player.h"
#endif

Additional code (end of document):

static void ScreenOver_f( void )
{

IMaterial *pMaterial = materials->FindMaterial( "effects/combine_binocoverlay", TEXTURE_GROUP_OTHER, true );
// Final material "HUDoverlays/nightvision"

{
static bool bDisplayed;
bool IsDisplayed;

{


if( bDisplayed )
{
// turn it off
view->SetScreenOverlayMaterial( NULL );
// Deactivate the 'light'
cvar->FindVar("mat_fullbright")->SetValue(0);
CLocalPlayerFilter filter;
C_BaseEntity::EmitSound( filter, 0, "Sole Survivor.NightVisOff" );
//play the off sound
IsDisplayed = false;
}
else
{
// turn it on
view->SetScreenOverlayMaterial( pMaterial );
// Activate the 'light'
cvar->FindVar("mat_fullbright")->SetValue(1);
CLocalPlayerFilter filter;
C_BaseEntity::EmitSound( filter, 0, "Sole Survivor.NightVisOn" );
IsDisplayed = true;
}

bDisplayed = !bDisplayed;

if( IsDisplayed = true )

{
#if defined( CLIENT_DLL )
C_BaseHLPlayer *pHLPlayer = assert_cast<C_BaseHLPlayer*>( player );

if ( pHLPlayer->m_HL2Local.m_flSuitPower > 30 )
pHLPlayer->m_HL2Local.m_flSuitPower = max( pHLPlayer->m_HL2Local.m_flSuitPower - 25, 0 );
else
return false;
#endif
}

}
}
}

I would be grateful for any more assistance - and thanks to those who have helped already!

[razvan252]

where youget the error declare the player like this:
CBasePlayer *pPlayer = ToBasePlayer( GetOwner() );

[Carbonis]

I presume that I will need to include another header - as GetOwner() is not a member of my current headers. Are you sure that your solution is correct? At the moment I just keep on getting even more errors

[Lolmen]

Use a communication between server to client for manipulating an nightvision from server on the client.

[Carbonis]

Use a communication between server to client for manipulating an nightvision from server on the client.

The question I have been asking on this thread for the last couple of times is how do I enable the server to communicate with the client?

Thanks

[Carbonis]

How do you make a communication between server to client for manipulating an nightvision from server on the client?

[Winston]

Is this is still the issue with the line C_BaseHLPlayer *pHLPlayer = assert_cast<C_BaseHLPlayer*>( player );?

If so, then replace player with C_BasePlayer::LocalPlayer() (or it might be C_BasePlayer::GetLocalPlayer(), I don't have the code right now) - otherwise, what exactly are you trying to send with this "communication?"

[Carbonis]

What I am trying to send is the signal (from view_scene.cpp) to drain the aux power (sever side) when the Nightvision overlay is applied.

[Carbonis]

Aha, I might actually have this solved - yet one problem not related to any other has occured.

well, replace "return false" with just "return" and you won't be returning a value.
Also, you appear to have several braces ( { & } ) that dont really say or mean anything, so I suggest you get rid of them. From that snippet, remove the 2nd & 3rd ones, and the last two. You only need them for defining a "section" of code, eg if ( some condition )
{
Do this
Also do this
And this
}
else
do this only
do this, regardless of the last if
Indentation also makes this logic easier to see
