Binding new Keys that run clientside functions. Created 4 years ago2020-01-21 15:36:53 UTC by abbadon

I am studying this tutorial trying to understand how to make that, when a impulse command is activated a function that is in the clientside part (cl.dll) runs.

Binding New keys TUT

But I cannot find a good solution for it, although I know that the weapon code is shared between client and server projects, overall if I try to use the function I want into the "impulse" cases part in the server side.

I DON´T know how to do it.
If there are any examples of that, please tell me where they are to study them so I can implement the method.

So you want to make a new key, which will basically do something completely clientside, right?
That tutorial shows you how to do things on the serverside. It is using client commands to do the job.

When you bind a key, like "firemode", e.g. bind x firemode, and then you press that key, it will send a client command, which will go from the client to the serverside.

The serverside handles it all in ClientCommand()You should know that pcmd is the string, which you are gonna compare, for example if pcmd's contents are equal to "firemode".
However, you're looking at the wrong place.

If you want to do things ENTIRELY on the clientside, you can easily do everything there. Just look at input.cpp Inside InitInput(), you can connect commands to an existing function on the clientside.
Here are several examples:However, in order to make any use of this, I gotta ask you, what are you exactly trying to do with a new keybind? Is it toggling a weapon fire mode, or is it meant to do something else?

It is supposed to use this two functions:

ShowScope ();
HideScope();

That is, the HUD overlay shown OVER the player HUD.Is the frame rectangle with the letters, the space for the radar, etc. When I hide the HUD (HIDEHUD_ALL) the frame persists, and the two functions that create and erase the frame are those two.

Hmm. This might be a bit more complicated since we gotta toggle a button. I'll see a bit more about this tomorrow.

But either way, input.cpp is the right place for this stuff and that's what I know for sure.

I did the duck part for the SIEGE position!!, the problem is that it was applied to IN_ keys, so I can´t figure how to do it for commands like "ShowScope" or "HideScope" as the impulse commnads do in the server side part:

	case 102:
       CLIENT_PRINTF( ENT(pev), print_console, "Radar System OFF \n" );
       EMIT_SOUND(ENT(pev), CHAN_VOICE, "player/radaroff.wav", 1, ATTN_NORM);
       radar_on = 0;
       MESSAGE_BEGIN( MSG_ONE, gmsgRadar, NULL, pev );
       WRITE_BYTE(0);
       MESSAGE_END();
       break;

Any material you´ll need just ask. Thank you so much Admer.

Done!! I have do some testings and discovered that I don´t need the IN_ whatever part, just create the command inside the client part and call the "showhud" part inside the code that handles the toggle mechanism. Now it works very well!!, pity that I don´t know how to put it in the kb_act.lst file so I can execute the impulse command that disables the HUD (HIDEHUD_ALL) and the command "showhud" at the same time... I mean, bind ONE key for two commands, of course.

You don't have to bind one key to call both showhud and impulse 102.
Instead, on the clientside, inside showhud's function, you can do something like EngineClientCmd( "impulse 102" ). Dunno if it's gonna exactly work, but it could be worth a try.

Alternatively, you can do the CLIENT_PRINTF part and the sound emitting part both on the clientside, unless you really need it on the serverside.

If the EngineClientCmd part doesn't work, we can hack it.
Call EngineClientCmd( "showhudsrv" ), and in the ClientCommands function in client.cpp, add an else if line where you'll compare pcmd to "showhudsrv", and inside of that, you're gonna change the player's pev->impulse to 102.
It's a bit ugly, but, there's always a workaround for everything.

HOW I DO IT

AKA: the absolute dummies method!!

NOTE: All credit must go to Sluggo the author of the original tutorial of which I commit the heresy of modifying it in the authentic Abbadon´s Clumsy Coding style!!

In your CLIENT workspace just do this for creating toggle keys:

In hud.cpp

Under

#include "vgui_scorepanel.h"

Put

bool g_bShowHudToggle;// Or whatever key you want

Inside

//DECLARE_MESSAGE(m_Logo, Logo)
int __MsgFunc_ResetHUD(const char *pszName, int iSize, void *pbuf)
{
return gHUD.MsgFunc_ResetHUD(pszName, iSize, pbuf );

Put

g_bShowHudToggle = false;

Inside

// This is called every time the DLL is loaded
void CHud :: Init( void )
{

Put

g_bShowHudToggle = false; 

Now in input.cpp

Under

extern int g_iAlive;

Put

extern bool g_bShowHudToggle;

Under

kbutton_t	in_graph;  // Display the netgraph

Put

kbutton_t   in_showhud;

Under

void IN_DuckUp(void) {KeyUp(&in_duck);}

Put

void IN_ShowHudToggle( void ) {g_bShowHudToggle = !g_bShowHudToggle;}

Now into

int CL_ButtonBits( int bResetState )
{

Put

//=============================
	if ( g_bShowHudToggle )
	{
	 Yourstuff here...
	}
//==============================

And into

void InitInput (void)
{

Put

gEngfuncs.pfnAddCommand ( "showhud", IN_ShowHudToggle);

Probably into both input.cpp and hud.cpp you must put...

#include "vgui_TeamFortressViewport.h"

...because I cannot remember if, because I add the "showhud" stuff there (the function that shows and hides the Combat HUD), the compiler needs it to build the client.dll.

Now in your kb_act.lst file into the yourmod\gfx\shell folder of your mod just add (I am using my code here as an example):

"showhud"				"Combat Screen Reticle CSR ON"

I hope that it works for you too.

I will try your method for the bind keys!. Thanks Admer!
Done...with some issues, but it works!!, BTW: How can I do the emitting sound in the client part? (and, BTW, the "monster following another monster" thingy forgotten ages ago, I swear I tried all but with no luck, haha!!!)

thread here...

Sound emitting is done via PlaySound(), if I remember correctly, you can find examples of its usage in ev_hldm.cpp

Oh. I found tons of errors when I try to use sounds...my bad coding again.

Compile time error or game crashes?

If the game crashes when playing the sound, you gotta precache the sound in ClientPrecache().

Oh nothing of that, just that I use the:

EMIT_SOUND(ENT(pev), CHAN_VOICE, "player/hudon.wav", 1, ATTN_NORM);

I obtain:

E:\DevZWC20\Elementos Basicos MAYO 2017\Single-Player Source\cl_dll\input.cpp(902) : error C2065: 'EMIT_SOUND' : undeclared identifier

BTW: i need spoonfeeding with the gunners following the trolleys. I have added the Nebuchadnezzar ship to the map, the Ganesha and Caduceus are ready too, I´m rewriting the manual, the mod is finished except for that part. I really can left that undone, I did it with the trolley code ages ago in 2008, but it could be cool if that part could be added before I can consider dinished the mod finally.

EMIT_SOUND is for the serverside.

On the clientside, you can use something like this:

gEngfuncs.pEventAPI->EV_PlaySound( idx, origin, CHAN_WEAPON, "weapons/pl_gun3.wav", gEngfuncs.pfnRandomFloat(0.92, 1.0), ATTN_NORM, 0, 98 + gEngfuncs.pfnRandomLong( 0, 3 ) );

Or a much simpler version, which can be found in `cl_util.h`:

inline void PlaySound( char *szSound, float vol ) { gEngfuncs.pfnPlaySoundByName( szSound, vol ); }

Example usage:

PlaySound("common/wpn_moveselect.wav", 1);

As for the gunners following the trolleys, I dunno, how do you exactly mean following them?
Are they in-air, on-ground, or?

They must get close to the trolley guys, as a bodyguard.
I will try your sound method!!. Thanks for helping me in this last steps!

BTW:

	//======================================
	// Mostrar-Esconder HUD HUD
	//======================================

	if ( g_bShowHudToggle )
	   	{

			gHUD.m_iHideHUDDisplay &= ~ HIDEHUD_WEAPONS;
            gHUD.m_iHideHUDDisplay &= ~ HIDEHUD_HEALTH;
			gHUD.m_iHideHUDDisplay &= ~ HIDEHUD_ALL;
			gHUD.m_iHideHUDDisplay &= ~HIDEHUD_FLASHLIGHT;
			if ( CL_IsThirdPerson ()) { gViewPort->ShowHud1(); gViewPort->HideHud();}
			if ( !CL_IsThirdPerson ()) { gViewPort->ShowHud(); gViewPort->HideHud1();}

			PlaySound("player/hudon.wav", 1);//(c)Admer


		}

		if ( g_bHideHudToggle )
		{
			gHUD.m_iHideHUDDisplay |=  HIDEHUD_WEAPONS;
			gHUD.m_iHideHUDDisplay |=  HIDEHUD_HEALTH;
			gHUD.m_iHideHUDDisplay |=  HIDEHUD_FLASHLIGHT;
			gViewPort->HideHud();//HUD reticle Firstperson
			gViewPort->HideHud1();//HUD reticle Thirdperson

			PlaySound("player/hudoff.wav", 1);//(c)Admer

		}


//=============================

It compiled fine this way!!

"They must get close to the trolley guys, as a bodyguard."

Still doesn't tell me what exactly the movement is supposed to be.
Is it aerial?

No. The Gunner guys walk and run, and the trolleys do the same. What I want is that the gunners follow the movement of the trolley guys that also walks and run. Once they spawn, the trolley guys run to "attack" (give ammo) the player, or the bot that has no ammo loaded, and I want the gunners (that spawn at the same time) follow the trolley guy at a given distance, instead of running or standing still engaging combat, I want them to engage combat BUT always keeping distance with the trolley guys, as if they are tied with a beam that has a fixed lenght.

Hmm.
TBH I don't do HL AI programming just yet, so I can't really help you on that one.

Don´t you worry. I repeat, that´s s feature that can wait, or maybe it will not be added once I finish this v2.0 of the mod. I have played this morning a full match and find that it is almost done, some little polishment in the health and damage of certain npcs and that´s all the code left I can do. I think it´s time to led Zion Warcry sourcecode have a rest.
