Revision as of 21:23, 15 October 2014

This is for SourceMod plugin development involving the TF2 Vote System. If you are looking into the details on configuring TF2 Voting on your TF2 server, see Voting on the Official Team Fortress Wiki.

Team Fortress 2 has a new VGUI voting system based on the Left 4 Dead Voting system and is controlled by Game Events and User Messages. You can use either a string from the resource file, or TF_playerid_noteam which will let you create any vote you want.

How voting works

  1. A client issues a callvote with the vote type and argument, or the server calls a vote (server uses entity index 99).
  2. The server sends a vote_options event.
    • For Yes/No votes, the values it sends are Yes and No (in that order). For Multiple Choice votes, the actual vote options are sent.
  3. The VoteStart User Message is sent, the last argument determines the vote type.
  4. Clients use the "vote" command to register their votes (option1 through option5), after which the server sends a vote_cast event with a 0-based option number (so option1 = 0, option5 = 4). It also updates the vote_controller entity's vote counts.
  5. When the vote is complete, the server sends either a VotePass or VoteFailed User Message.

Server Entity

The server should update this as appropriate. Unfortunately, the valid values for m_iActiveIssueIndex is unknown.

Name: vote_controller (CVoteController)
Structure:
int m_iActiveIssueIndex Number of the active issue
int m_iOnlyTeamToVote Corresponds to VoteStart's team argument.
int[5] m_nVoteOptionCount Table of 5 vote counts numbered 0-4
int m_nPotentialVotes Number of players eligible to vote
int m_bIsYesNoVote Corresponds to VoteStart's yesno argument


Console Commands

callvote

Note: This command can take 0 arguments. If it does, a VoteSetup usermessage is returned to that user.

Name: callvote
Structure:
string type "Kick", "RestartGame", "ChangeLevel", "NextLevel", "ScrambleTeams", or "ChangeMission". Should return VoteSetup Usermessage if left blank.
string param1 "userid_short kicktype_string" for Kick, map name for Changelevel/NextLevel, or popfile for ChangeMission. Otherwise, left blank


kicktype_string is one of these (at least in the English version):

  • other
  • cheating
  • idle
  • scamming

This data is primarily there if you want to intercept these messages in a plugin.

CallVoteFailed UserMessage is sent back if a vote cannot be called unless a vote is already being displayed.

vote

Note: This command is only valid when a vote is ongoing.

Name: vote
Structure:
string option F1 is "option1", F2 is "option2", F3 is "option3", F4 is "option4", F5 is "option5"


Note that these are 1-based, but the vote_cast event is 0-based.

User Messages

Note: These user messages use unsigned bytes for the team number. Since the October 15, 2014 update, all teams is now represented by 0 (it used to be -1 / 255)


The User Messages that exist in the TF2 Voting system are:

VoteSetup

Note: Sent to a player when they load the Call Vote screen (which sends the callvote command to the server), lists what votes are allowed on the server
{{qnotice|This changed in the October 15, 2014 update

Name: VoteSetup
Structure:
byte issue_count Count of vote issues allowed on this server. Not present in protobuf version
repeated message issue issue fields as shown below


Name: issue
Structure:
string potential_issue Vote issue name that will be sent for the callvote command
string translation name Translation name, such as #TF_Issue_NextMap
bool enabled true if this issue is enabled, false if not


There is one string sent for each supported issue. Valid strings are:

  • Kick
  • RestartGame
  • ChangeLevel
  • NextLevel
  • ScrambleTeams
  • ChangeMission

Disabled issues can be either omitted or followed by " (Disabled on Server)". The default is to omit them (sv_vote_ui_hide_disabled_issues 1).

CallVoteFailed

Note: Sent to a player when they attempt to call a vote and fail.

Name: CallVoteFailed
Structure:
byte reason Failure reason (1-2, 5-10, 12-19)
short time For failure reasons 2 and 8, time in seconds until client can start another vote. 2 is per user, 8 is per vote type.


Valid Failure Codes are:
1 - VOTE_FAILED_TRANSITIONING_PLAYERS - Cannot call vote while other players are still loading. This appears to be a holdover from L4D2; use code 10 instead.
2 - VOTE_FAILED_RATE_EXCEEDED - You called a vote recently and cannot call another one for X seconds (second argument to CallVoteFailed specifies the number of seconds)
5 - VOTE_FAILED_ISSUE_DISABLED - Server has disabled that issue.
6 - VOTE_FAILED_MAP_NOT_FOUND - That map does not exist.
7 - VOTE_FAILED_MAP_NAME_REQUIRED - You must specify a map name
8 - VOTE_FAILED_FAILED_RECENTLY - This vote failed recently
9 - VOTE_FAILED_TEAM_CANT_CALL - Your team cannot call this vote
10 - VOTE_FAILED_WAITINGFORPLAYERS - Voting not allowed while Waiting for Players
11 - VOTE_FAILED_PLAYERNOTFOUND - Doesn't appear to work
12 - VOTE_FAILED_CANNOT_KICK_ADMIN - Can't Kick Server Admin
13 - VOTE_FAILED_SCRAMBLE_IN_PROGRESS - Vote Scramble is pending
14 - VOTE_FAILED_SPECTATOR - Spectators can't vote
15 - VOTE_FAILED_NEXTLEVEL_SET - Next level already set
16 - VOTE_FAILED_MAP_NOT_VALID - Map is not in the map list
17 - VOTE_FAILED_CANNOT_KICK_FOR_TIME - Cannot kick yet. Used for MvM
18 - VOTE_FAILED_CANNOT_KICK_DURING_ROUND - Cannot kick during round. Used for MvM
19 - VOTE_FAILED_MODIFICATION_ALREADY_ACTIVE - Modification is already active, used by Eternaween

VoteStart

Events

Server to Client Events

vote_cast

Note: Sent to all players when a player chooses a vote option (or more specifically, the server receives a vote command)

Name: vote_cast
Structure:
byte vote_option which option the player voted on
short team [Ed: Usually -1, but team-specific votes can be 2 for RED or 3 for BLU]

string option5


If sv_vote_issue_nextlevel_allowextend is set to 1, option5 is "Extend current Map"

Client-only Events

These events are passed between the TF2 client and the client's VGUI voting panels. They have no server interaction and the server should not be touching them in any way.

vote_ended

Name: vote_ended
Structure:


vote_started

Name: vote_started
Structure:
string issue
string param1
byte team
long initiator entity id of the player who initiated the vote


vote_changed

Note: These values are read from the vote_controller entity on the server

Name: vote_changed
Structure:
byte option1
byte option2
byte option3
byte option4
byte option5
byte potentialVotes


vote_passed

Name: vote_passed
Structure:
string details
string param1
byte team


vote_failed

Name: vote_failed
Structure:
byte team


Example voting plugin

This is a basic plugin that starts a vote, "Is gaben fat?". It does not ensure the same client does not vote multiple times, nor does it actually kick the user.

#include <sourcemod>
// TF2's internal map vote uses client index 99 for the server
#define TF2_SERVER_CLIENT_INDEX 99
#define TF2_TEAM_ALL -1

new yesvotes;
new novotes;
#define MAX_VOTES 4

public Plugin:myinfo = 
{
	name = "Test Yes/No Vote",
	author = "Powerlord",
	description = "A test vote plugin for the AlliedMods wiki",
	version = "1.0",
	url = "http://wiki.alliedmods.net/TF2_Voting"
}

public OnPluginStart()
{
	RegConsoleCmd("testvote",Callvote_Handler);
	RegConsoleCmd("vote", vote);
}

public Action:Callvote_Handler(client, args)
{
	new Handle:bf = StartMessageAll("VoteStart", USERMSG_RELIABLE);
	BfWriteByte(bf, TF2_TEAM_ALL);
	BfWriteByte(bf, TF2_SERVER_CLIENT_INDEX);
	BfWriteString(bf, "#TF_playerid_noteam");
	BfWriteString(bf, "Is gaben fat?");
	BfWriteBool(bf, true);
	EndMessage();
	
	yesvotes = 0;
	novotes = 0;
	
	return Plugin_Handled;
}

UpdateVotes()
{
	if (yesvotes+novotes >= MAX_VOTES)
	{
		PrintToServer("voting complete!");
		if (yesvotes > novotes)
		{
			new Handle:bf = StartMessageAll("VotePass");
			BfWriteByte(bf, TF2_TEAM_ALL);
			BfWriteString(bf, "#TF_playerid_noteam");
			BfWriteString(bf, "Gaben is fat");
			EndMessage();
		}
		else
		{
			new Handle:bf = StartMessageAll("VoteFailed");
			BfWriteByte(bf, TF2_TEAM_ALL);
			// Check list of failure reasons
			BfWriteByte(bf, 3);
			EndMessage();
		}
	}
}

// If the TF2 vote system is running (sv_allow_votes 1), this needs to be a command listener
// because TF2 registers the vote command only when a vote is ongoing, and thus hooking it using RegConsoleCmd doesn't work.
public Action:vote(client, args)
{
	new String:arg[8];
	new option = 0;
	GetCmdArg(1,arg,8);
	PrintToServer("Got vote %s from %i",arg,client);
	if (strcmp(arg,"option1",true) == 0)
	{
		yesvotes++;
		option = 0;
	}
	else if (strcmp(arg,"option2",true) == 0)
	{
		novotes++;
		option = 1;
	}
	
	new Handle:msg = CreateEvent("vote_cast");
	SetEventInt(msg, "entityid", client);
	SetEventInt(msg, "team", -1);
	SetEventInt(msg, "vote_option", option);
	FireEvent(msg);
	
	UpdateVotes();
	return Plugin_Continue;
}
