// and to use it:
api -> SendClientMessage(playerID, 0xFFFFFFFF, "stuff");
Refer to the VCMP API for the function calls.

[habi]

thanks Xmair for pointing it out.
@MEGAMIND, in our template it is named VCMP
So VCMP->SendClientMessage(......)

You need to replace playerID with the player's ID.

how do i send to all isntead of a playerid

[habi]

i just made one, it is working

Code Select Expand

char buf[10];
        for ( int i = 0; i <  VCMP->GetMaxPlayers(); i++ )
        {
            int b = VCMP->GetPlayerName(i, buf, 10);
            if (b == 0)
            {
                VCMP->SendClientMessage(i, 0xFFFFFFFF, "hello");
            }
        }

            }
        }

ok plugins loads successfully but no ingame message

[Xmair]

I'm not sure about this but in Java, we pass null instead of the ID to message it to everyone. It might or might not work in C++, give it a try.

Are you using that code upon the plugin being loaded? If yes then it won't show any message because no players are connected to the server when the plugins are being loaded initially.

Code Select Expand

void playerCreated(int32_t playerId) {
VCMP -> SendClientMessage(playerId, 0xFFFFFFFF, "hello");
}

unsigned int VcmpPluginInit(PluginFuncs* pluginFuncs, PluginCallbacks* pluginCalls, PluginInfo* pluginInfo) {
pluginCalls -> OnPlayerConnect = playerCreated;
}You should wrap up player and other entities into classes for better accessibility.

[habi]

In SQMain.cpp, find VcmpPluginInit function.

You can see a line
pluginCalls->OnServerInitialise = OnServerInitialise

This is attaching the function on Right hand side to server. Right hand side can be renamed as anything you like. But there must be a function with that name.

Also to make the function,  you can see it's details by moving mouse to pluginCalls->onPlayerConnect


So

Code Select Expand

void myFunction( int32_t playerID )
{
//your code
}

Thanks to @Xmair & @habi Solved, locking topic..
