RemoteEvents Assistance

Help and Feedback Scripting Support
#1

I have recently came back on ROBLOX to script and the one thing I find to struggle with is RemoteEvents. I understand somewhat of the concept but what I want to seek an answer for is how can I transfer player information from one place to another.

Let me stretch it out a bit. If you go to my other topic I recently wrote, I asked on how I can make a certain GUI appear on a certain player. I want to use the same idea and add it something else.

If anyone doesn’t mind explaining how information, or in this case, a player’s name, can be transferred from one place to another.

#3

If I am understanding correctly, you want to pass info to different places within the same game?

#4

Well, kind of yeah. I am trying to make a feature where if a player touches a certain part, a text from a billboard GUI gets changed into the player’s name.

#5

Well, you wouldn’t need a RemoteEvent for that.

local part = (Part)

part.Touched:Connect(function(hit)
    local hum = hit.Parent:FindFirstChild("Humanoid")
    if hum then
        --It's a player
        local chr = hit.Parent
        local plr = game.Players:GetPlayerFromCharacter(chr)
        local textLabel = (textLabel in billboard gui)
        textLabel.Text = plr.Name
    end
end)

Edit: Unless you want the billboard gui text to be seen only by the player and nobody else

#6

So, how would it work if it was only meant to be seen on the player’s screen?

#7

You could change that script to a LocalScript if you want it to be client-sided (Or visible to you only and not to everyone else)

Just make sure to define your Part where it is & put it inside StarterPlayerScripts

#8

Then you would have to fire a remoteevent to the player.

Create a RemoteEvent in ReplicatedStorage(presumably in a folder), and name it something like “BillboardDetection”

Then, in a regular script, put this:

local part = (Part)

part.Touched:Connect(function(hit)
	local hum = hit.Parent:FindFirstChild("Humanoid")
	
	if hum then
		local chr = hit.Parent
		local plr = game.Players:GetPlayerFromCharacter(chr)
		local textLabel = (textLabel)
		game.ReplicatedStorage.BillboardDetect:FireClient(plr,textLabel)
	end
end)

In a localscript, put this


game.ReplicatedStorage.BillboardDetect.OnClientEvent:Connect(function(textLabel)
	textLabel.Text = game.Players.LocalPlayer.Name
end)

Thank you for informing on my issue but I also do want to learn from this so I have a question. When I fire an event, what do I put in the parenthesis. Like the example given, why was the second argument in the regular script, textLabel and the first argument in the LocalScript, “textLabel”

#10

When you are firing a RemoteEvent from a server script, you have 2 options:

RemoteEvent:FireClient(certainPlr) – Fires to a specific player, specification needed

RemoteEvent:FireAllClients() --Fires to all players, no specification needed

Pretend the first argument is like a direction to the server on which player to fire to

When you are firing a RemoteEvent from a local script to the server, you would just put your parameters

RemoteEvent:FireServer([parameters])

However, when receiving this from a server script, you need to include the player who fired the remote event as the first argument

RemoteEvent.OnServerEvent(plrWhoFiredTheEvent, [parameters])

#11

Could you give an example for RemoteEvent:FireClient

#12

Since the server doesn’t know what player to exactly look for, you need to pass a Player object when using FireClient()

game.Players.PlayerAdded:Connect(function(Player)
    game.ReplicatedStorage.RemoteEvent:FireClient(Player, WhateverElse)
end)

Doing it like this:

game.Players.PlayerAdded:Connect(function(Player)
    game.ReplicatedStorage.RemoteEvent:FireClient(WhateverElse)
end)

How would the server know which player to fire this to? :thinking:

#13

Ahh, this makes more sense, thank you.
