Switching to the next player - Scenario - 21.08.2011

Hello there.

I am currently attempting to form an advanced spectating system and I would like to make it so a player could press a button and then they would spectate the next connected player. How can I do this properly? I want to avoid unconnected players obviously...

Re: Switching to the next player - Machida - 21.08.2011

To avoid unconnected users you can use IsPlayerConnected(playerid) .
And about the Keys i think you should use GetPlayerKeys..https://sampwiki.blast.hk/wiki/GetPlayerKeys
And when the key is pressed, You should spectate the current player id +1, ofc if its connected.

Like (not real code) :

if GetPlayerKeys then

if IsPlayerConnected(playerid) then
// Spectated playerid +1

end if

end if

Im a newbie, but i think its something like that.
I code C++ but i started to pawn now xD

I understand how to do those things. Although, my problem is what do I do if the ID used in "IsPlayerConnected" isn't connected? Should I just do "check_id++"?

Are you using zcmd, strcmp, dini .. ? Which one are you using ?

Yes, if its not connnected add 1, then check again, etc..

ZCMD

Re: Switching to the next player - Lorenc_ - 21.08.2011

pawn Code:

SpectatePlayer(playerid, whoid + 1);

Like that? Though you need to check if the player ID is connected if he isn't return 0 or just add another + 1 to check again.

Re: Switching to the next player - Deskoft - 21.08.2011

Basically, what Lorenc_ said.

pawn Code:

if(IsPlayerConnected(whoid + 1))
{
        SpectatePlayer(playerid, whoid + 1);
}else{
        SendClientMessage(playerid, 0xFF0000, "Player is not connected");
}

Is that what you need? That's basically using Lorenc_'s example, and checking if he is connected.

Edit: Also, if he is not connected, go to the next id, if it's not connected, switch to the next id... and so on.

Re: Switching to the next player - Scenario - 21.08.2011

Kind of. Although, why are you using "whoid + 1" instead of "whoid?" Why are you adding the one to the ID?

I am trying to make it so if a player isn't connected, it moves to the next ID. It should keep doing that until it finds a connected ID. Any thoughts?

Re: Switching to the next player - Lorenc_ - 21.08.2011

Ok, let say you're spectating ID 1 and you want to move to ID 2 then 3

Whoid = ID 1

pawn Code:

if((keys & KEY_FIRE))
{ 
    if(IsPlayerConnected(whoid + 1))
    {
            SpectatePlayer(playerid, whoid + 1);
    }else{
            SendClientMessage(playerid, 0xFF0000, "Player is not connected");
    }
}

Come on, you should understand my post and Deskoft's..

Oh Jesus... I am honestly being stupid right now... I guess this is from those beers I had a couple hours ago! I don't normally drink, but I needed a beer after doing yard-work all day yesterday (it's 1:34 AM here now).

I understand this absolutely perfect now, I can't believe I didn't think this through very much! Like I said though... alcoholic beverages...

Thanks guys!

Re: Switching to the next player - Deskoft - 21.08.2011

Oh! Now I understand what you want to do!

pawn Код:

new found;
    new existingid;
    new newid;
    do
    {
        existingid++;
        if(IsPlayerConnected(existingid))
        {
            newid == existingid;
            found == 1;
        }
    }while( found == 1);

So basically, when that loop happens, newid will be the id to spectate. I didn't test it, but I guess that should work. right?

Re: Switching to the next player - Scenario - 21.08.2011

I basically need a function which will choose the next available player ID.

For example:

I am spectating player ID 43 and I want to spectate the next player, I push LMB and it should advance to the next player (i.e. ID 52). I don't want to need to push LMB 9 times in order to get to ID 52- it should automatically choose the next player and return the ID.

Does this make sense?

There is an EXACT example of what you're trying to accomplish in the Barron gamemode that comes with the SA:MP Server Package.

Honestly, I don't see a system in there that does this...

Re: Switching to the next player - Bakr - 21.08.2011

pawn Код:

new gPlayerObserving[MAX_PLAYERS]; // player observing which active player

ObserverSwitchToNextVehicle(playerid)
{
    new x=0;
    while(x!=MAX_PLAYERS) { // MAX_PLAYERS iterations
        gPlayerObserving[playerid]++;
        if(gPlayerObserving[playerid] == MAX_PLAYERS) {
            // we need to cycle back to the start
            gPlayerObserving[playerid] = 0;
        }
        // see if the target player has a vehicle,
        // if so assign this player to observe it
        if(gPlayerVehicles[gPlayerObserving[playerid]] != 0) {
            PlayerSpectateVehicle(playerid,gPlayerVehicles[gPlayerObserving[playerid]]);
            return;
        }
        x++;
    }
    // didn't find any vehicles to observe. we'll have to default to last
    PlayerSpectateVehicle(playerid,gPlayerVehicles[gPlayerObserving[playerid]]);
}

//OnPlayerKeyStateChange
if(gPlayerObserving[playerid] >= 0 && IsKeyJustDown(KEY_FIRE,newkeys,oldkeys)) {
       // They're requesting to change observer to another vehicle.
       ObserverSwitchToNextVehicle(playerid);
    }

//OnPlayerDeath
new x=0;
    while(x!=MAX_PLAYERS) {
        if(x != playerid && gPlayerObserving[x] == playerid) {
            ObserverSwitchToNextVehicle(x);
        }
        x++;
    }

You should be able to create your own system, very easily, based on the system in that script.
