Ending Matches | Dokümantasyon - Roblox Yaratıcı Merkezi

Matches can end in a few conditions including timers running out or a single player being left.

Managing Defeated Players

Right now, defeated players respawn in the arena. Instead, send them back to the lobby to wait for the next match.

In PlayerManager, create a local function named respawnPlayerInLobby(). In that function, do the following:

Set the player's RespawnLocation property to the lobbySpawn.
Reload the character with Player:LoadCharacter(). Remember, LoadCharacter() recreates the player at their spawn, removing any tools they had.

Using Anonymous Functions

Anonymous functions are commonly used in advanced scripts under specific situations. Before defining them, it's important to understand a situation your script may encounter.

Consider this: To teleport defeated players to the lobby, the respawn function will have to be connected to the player's Died event. There is a problem though. If you connect the event as we have in the past, there's no way to get the name of the player from the Died event. The script needs that name to remove a defeated player from the table tracking active players.

To get the name of the player that triggered the Died event, use an anonymous function. Anonymous functions don't have names, and can be created directly within Connect() rather than separately.

A sample anonymous function is below that shows the syntax.


myPlayer.Died:Connect(function()
	print(player)
end)

Coding the Died Event

For this function, whenever a player's character dies, they'll trigger the function that respawns them.

To get access to the player's Died event, in PlayerManager > preparePlayer(), add a variable for the player's humanoid.


local function preparePlayer(player, whichSpawn)
	player.RespawnLocation = whichSpawn
	player:LoadCharacter()

	local character = player.Character or player.CharacterAdded:Wait()
	local sword = playerWeapon:Clone()
	sword.Parent = character

	local humanoid = character:WaitForChild("Humanoid")
end

Create an anonymous function that connects to the Died event. Start by typing humanoid.Died:Connect(). Then, inside Connect(), type function(), press Enter to autocomplete end, and delete the extra parenthesis.


local humanoid = character:WaitForChild("Humanoid")

humanoid.Died:Connect(function()

end)

In the anonymous function, call respawnPlayerInLobby(). Pass in player, a variable storing the player getting ready to enter a match.


local humanoid = character:WaitForChild("Humanoid")

humanoid.Died:Connect(function()
	respawnPlayerInLobby(player)
end)

Start a server and play a match. Test that when a player dies, they respawn in the lobby. To defeat players, walk up to them and use your weapon until you can confirm they've respawned in the lobby.

Note, there are also some different ways of testing if desired.

To kill a player, in the Server > Output Window > Command Bar, copy and paste: workspace.Player1.Humanoid.Health = 0. Press Enter to run the command. To remove other players, use Player2, Player3, etc.
Setting GameSettings > matchDuration to a longer time can give you more time to find and take out all players.
To have quicker tests, change GameSettings > minimumPlayers to smaller number, like 2.

Ending the Game

Now that defeated players respawn, start working on ending the game. Remember creating the MatchEnd event? It'll be fired when either the timer runs out or a winner is found.

To tell other scripts which condition ended the game, create a table with variables for TimerUp and FoundWinner. When the match end event fires, it'll pass in a variable so other scripts can respond.

In GameSettings, create an empty module table named endStates.


local GameSettings = {}

-- Game Variables
GameSettings.intermissionDuration = 5
GameSettings.matchDuration = 10
GameSettings.minimumPlayers = 2
GameSettings.transitionTime = 5

-- Possible ways that the game can end.
GameSettings.endStates = {
}

return GameSettings

Create two variables named TimerUp and FoundWinner. Set each to a string matching their name. These strings will be used to test the code.


GameSettings.endStates = {
	TimerUp = "TimerUp",
	FoundWinner = "FoundWinner"
}

Ending with a Timer

When the timer ends, fire the Match End event and send the matching end state variable. That way, other scripts listening for that event can respond accordingly. Remember that while events fire signals, that can also send data that's received by listening scripts, like TimerUp or FoundWinner.

In GameManager, in the while true do loop, find the line matchEnd.Event:Wait(). At the start of the line, add local endState =.


while true do
	displayManager.updateStatus("Waiting for Players")

	repeat
		task.wait(gameSettings.intermissionDuration)
	until #Players:GetPlayers() >= gameSettings.minimumPlayers

	displayManager.updateStatus("Get ready!")
	task.wait(gameSettings.transitionTime)

	matchManager.prepareGame()
	local endState = matchEnd.Event:Wait()
end

To confirm that the correct state was received, add a print statement including endState.


while true do
	displayManager.updateStatus("Waiting for Players")

	repeat
		task.wait(gameSettings.intermissionDuration)
	until #Players:GetPlayers() >= gameSettings.minimumPlayers

	displayManager.updateStatus("Get ready!")
	task.wait(gameSettings.transitionTime)

	matchManager.prepareGame()
	local endState = matchEnd.Event:Wait()
	print("Game ended with: " .. endState)
end

In MatchManager, find timeUp() and remove the print statement. Then, to fire the match end event, type matchEnd:Fire() and pass in gameSettings.endStates.TimerUp.


-- Values
local displayValues = ReplicatedStorage:WaitForChild("DisplayValues")
local timeLeft = displayValues:WaitForChild("TimeLeft")

-- Creates a new timer object to be used to keep track of match time.
local myTimer = timer.new()

-- Local Functions
local function timeUp()
	matchEnd:Fire(gameSettings.endStates.TimerUp)
end

Test a match. Once the timer runs out, check that the print statement includes the string stored in the TimerUp variable.

Troubleshooting Tips

At this point, the message wasn't displayed, try one of the following below.

Check that wherever the end state variables are called, that they're written exactly, like here: gameSettings.endStates.TimerUp.
Make sure to use : (colon operator) with the Fire() instead of the dot operator, like in matchEnd:Fire().

Coding a Winning Match

Next, the script needs to identify winning players, remove losing players, and run cleanup such as stopping the timer. Matches will also end if one player is left. To see if the FoundWinner condition is met, you'll need a function that checks the number left in the table tracking players in a match.

Checking Player Count

Matches will end if there's only one player left. To check this, the script needs to track the players in a round. Once one player is left, a winner can be assigned.

In PlayerManager, define the following variables:

ModuleScripts folder
GameSettings module - Used to access end state variables
Events folder and the MatchEnd event - Fires event


local PlayerManager = {}

-- Services
local Players = game:GetService("Players")
local ServerStorage = game:GetService("ServerStorage")
local ReplicatedStorage = game:GetService("ReplicatedStorage")

-- Modules
local moduleScripts = ServerStorage:WaitForChild("ModuleScripts")
local gameSettings = require(moduleScripts:WaitForChild("GameSettings"))
-- Events
local events = ServerStorage:WaitForChild("Events")
local matchEnd = events:WaitForChild("MatchEnd")

Above respawnPlayerInLobby(), add a new local function named checkPlayerCount().


-- Player Variables
local activePlayers = {}
local playerWeapon = ServerStorage.Weapon

local function checkPlayerCount()

end

local function respawnPlayerInLobby(player)

Remember, to be in scope, this function needs to come before the functions that will use it later in the script.

Within that function, use an if then statement to check for a winner. In that statement:

Check if the size of the activePlayers table is 1.
If so, fire matchEnd and pass in gameSettings.endStates.FoundWinner.


local function checkPlayerCount()
	if #activePlayers == 1 then
		matchEnd:Fire(gameSettings.endStates.FoundWinner)
	end
end

Removing a Player

An accurate count can't be kept unless players are removed. When a player is defeated, keep an accurate player count by removing them from the player table. Then, check the size of the active player table to see if there's a winner.

Under checkPlayerCount(), create a new local function named removeActivePlayer() with a parameter named player.


local function checkPlayerCount()
	if #activePlayers == 1 then
		matchEnd:Fire(gameSettings.endStates.FoundWinner)
	end
end

local function removeActivePlayer(player)

end

To find the player in the activePlayers table, iterate through it using a for loop. Then, add an if statement that runs if a player matching the name passed into the function is found.
```
local function removeActivePlayer(player)
	for playerKey, whichPlayer in activePlayers do
		if whichPlayer == player then

		end
	end
end
```
Keep similar variable names different. As you code, may sure you don't have overlapping variable names, like the above function which includes two versions of player: player and whichPlayer.
For instance, adding which to a variable name in an iterating table is a good convention to avoid confusion, such as whichPlayer or whichPart.

To remove the player, in the if statement:

Call table.remove(). Inside the parentheses, pass in activePlayers, the table to look in, and playerKey - the player to remove from the table.
Set the value of the playersLeft object to #activePlayers.
Check for a winning player by running checkPlayerCount().


local function removeActivePlayer(player)
	for playerKey, whichPlayer in activePlayers do
		if whichPlayer == player then
			table.remove(activePlayers, playerKey)
			playersLeft.Value = #activePlayers
			checkPlayerCount()
		end
	end
end

Connecting Events and Testing

To use the function just created, call it from within the anonymous function connected to the player's Died event.

Find preparePlayer(). In the anonymous function with the Died event connection, call removeActivePlayer(). Then, pass in the player as the parameter.


humanoid.Died:Connect(function()
	respawnPlayerInLobby(player)
	removeActivePlayer(player)
end)

To see if a winning player is found, start a test server. When there is only one player left you should see FoundWinner in the output window.
Continue testing and let the match end. Notice as a new match starts, an error appears in the Output Window:

This error is because the timer wasn't stopped, which will be fixed in the next section.

Stopping the Timer

Whenever a match ends with a winning player, the timer should stop as well. To halt the timer before time is up, have the timer stop whenever the match end event fires. This is one of the benefits of creating events. They can be reused in multiple situations to script cause and effect relationships.

In MatchManager, create a new local function named stopTimer(). Inside, type myTimer:stop() to halt the timer.


-- Creates a new timer object to be used to keep track of match time.
local myTimer = timer.new()

-- Local Functions
local function stopTimer()
	myTimer:stop()
end

local function timeUp()
	matchEnd:Fire(gameSettings.endStates.TimerUp)
end

To stop the timer when the match ends, connect the matchEnd event to stopTimer().


-- Module Functions
function MatchManager.prepareGame()
	playerManager.sendPlayersToMatch()
	matchStart:Fire()
end

matchStart.Event:Connect(startTimer)
matchEnd.Event:Connect(stopTimer)

return MatchManager

Test that the previous error no longer appears by starting a server. Eliminate all but one player and then wait a few seconds once the match ends.

Next Steps

While the two win conditions are finished, there are still some tasks left to finish the game loop. For instance, the winning player isn't ever teleported to the lobby. In the next lesson, you'll display how the match ended to players and reset the game, finally completing the whole loop.
