triggerClientEvent

[Anubhav]

Hello everyone!,

I want to ask that, how to trigger a event only for a player? It should render something only FOR HIM.

My server side code:

  
addEventHandler("onPlayerLogin", root, function() 
        triggerClientEvent(source,"createGUI", root) -- will it only trigger for him? D: 
        end 
    ) 
  

I'm not showing my full client sided code due to script leakings!

My client side code:

  
function startRendering(forWhom) 
        local whoToRender = forWhom or lp 
        addEventHandler("onClientRender", whoToRender, render) 
    end 
    addEvent("createGUI", true) 
    addEventHandler("createGUI", root, startRendering)

it should work, did you test it with multiple people?

[Anubhav]

I'll test it soon with multiple people.

I will reply tommorow maybe.

[Anubhav]

Another doubt:

  
function startRendering() 
        guiSetVisible(windowOne, true) 
    end 
    addEvent("createGUI", true) 
    addEventHandler("createGUI", root, startRendering) 
  

So will it set the window visible for everyone?

Depends on who you'll trigger the event. If you call the function startRendering(), it will execute the function for each client.

[Anubhav]

Can you give me a example for only the player who loginned? :-/

[DNL291]

Actually, your server-side code above is correct, but the another one is wrong.

Use this one:

function startRendering() 
    addEventHandler("onClientRender", root, render) 
end 
addEvent("createGUI", true) 
addEventHandler("createGUI", root, startRendering) 

It should work.

If I use guiSetVisible instead of addEventHandler( I removed dx functions. ), will it only be for that plr?

[DNL291]

If I use guiSetVisible instead of addEventHandler( I removed dx functions. ), will it only be for that plr?

Yes, of course.

But like I said, if you call startRendering without calling it for a specific player, the function will be called for all clients.

[Anubhav]

So if I do like this:

  
lp = localPlayer or getLocalPlayer() 
    addEventHandler("onClientPlayerJoin", root, function() 
            startRendering(lp) 
        end 
        ) 
  

correct?

[DNL291]

That function will be called for all players except the local player.

This event is triggered when a player joins a server. It is triggered for all players except the local player, as the local player joins the server before their client-side resources are started.

If that is what you want then it's right.

By the way, lp = localPlayer or getLocalPlayer() is useless. Change it to: lp = localPlayer

You do not have to do anything in Client .. because u sent the trigger For Player and Client just for local player

[Anubhav]

If I do it like this:

SERVER:

[lua]

addEventHandler("onPlayerJoin", root, function()

triggerClientEvent(source, "createGUI", root, source)

end

)

[#DRAGON!FIRE]

trigger will send just to player because in First arg u put player .. and arg 3 it's the source of event

[DNL291]

If I do it like this:

SERVER:

addEventHandler("onPlayerJoin", root, function() 
      triggerClientEvent(source, "createGUI", root, source) 
end 
) 

You can pass the player element as the source of the event instead of an argument.

Do you understand that a client can't affect another client at all?

addEventHandler("onPlayerLogin", root, function() 
  
        triggerClientEvent(source,"createGUI", source) -- due to first argument, this will trigger for 1 player and 3rd argument is for specifying source of the évent  
        end 
    ) 
  

  
local function startRendering () 
dxDrawText(...) 
end 
  
addEvent("createGUI",true) 
    addEventHandler("createGUI", root, 
     function() 
      addEventHandler("onClientRender", root, startRendering ) 
        end 
        ) 
  
  
  

EDIT: I changed the event name to "createGUI". I have no idea how I missed this

Stuff.

This event is triggered when a player joins a server. It is triggered for all players except the local player

As soon as a client joins the server, you just can use 'onClientResourceStart' (Remember to use the resource-root, not root! (Otherwise it will start by every resource that gets started)) or put: functionname() to start the function. Why? Because when she/he joins, the scripts get started.
