How to send text from server side?

[3HAXAPb94]

Hello, I have one problem I cant send text from server side to client side. I want to use dxDrawText

I use message = "My text"

[Dzejki]

You have to use triggering. Look how it works on wiki

[Dealman]

You can read this post for an example - it's from client to server. But should work the other way.

[3HAXAPb94]

--client

addEvent ("onUpgradeText",true) 
addEventHandler ("onUpgradeText",root,weaponBar) 
 function weaponBar(message) 
 if not message then  
 message = "no upgrade" 
dxDrawRectangle (posX*2+300,posY,250,100, tocolor (0,0,0,150)) 
dxDrawRectangle (posX*2+300,posY,250,Hvis, tocolor (255,255,255,150)) 
dxDrawText ("Upgrade",posX*2+300,-(vis)+50-(Hvis),sX,sY,tocolor (255,255,255,255),1.5,"default-bold", "center", "center") 
dxDrawText (message,posX*2+300,-(vis)+100-(Hvis),sX,sY,tocolor (255,255,255,255),2,"default-bold", "center", "center") 
 end 
    end 
 addEventHandler ("onClientRender",root, weaponBar) 
  

--server

  
function someFucntion () 
message = "Barrel" 
triggerClientEvent ("onUpgradeText",source,message) 
end 

its doesnt work...

[Dealman]

function someFucntion () 
message = "Barrel" 
triggerClientEvent ("onUpgradeText",source,message) 
end 

You don't have any event handler attached to this function, so as far as I can see - source would be nil. Also I believe you would have to construct your triggerClientEvent like this;

triggerClientEvent (source, "onUpgradeText", message) 

[3HAXAPb94]

Still not working.

[Dealman]

Ah, I mis-read the wiki. Try this;

triggerClientEvent (source, "onUpgradeText", getRootElement(), message) 

Source being the element you want to send the message to. Make sure there actually is a source for the function you're working with. Also if there are errors and/or warnings - post them.

[3HAXAPb94]

Debug empy and still not work...

[.:HyPeX:.]

Surely you havent done what he says, how are you triggering the function? (server)

[3HAXAPb94]

local luck = math.random(1,5) 
if luck == 1 then 
message = "Barrel" 
triggerClientEvent (source, "onUpgradeText", getRootElement(), message) 
giveMeBarrel () 
elseif luck == 2 then 
message = "Aura" 
triggerClientEvent (source, "onUpgradeText", getRootElement(), message) 
giveMeAura() 
elseif luck ==3 then 
message = "Fix" 
triggerClientEvent (source, "onUpgradeText", getRootElement(), message) 
fixVehicle ()  
elseif luck == 4 then 
message = "Nitro" 
triggerClientEvent (source, "onUpgradeText", getRootElement(), message) 
nitro () 
elseif luck == 5 then 
message = "Rocket" 
triggerClientEvent (source, "onUpgradeText", getRootElement(), message) 
doShoot() 
end 

Its server side

PS i use this if player get racepickup

addEvent ("onUpgradeText",true) 
addEventHandler ("onUpgradeText",root,weaponBar) 
 function weaponBar(message) 
 if not message then 
 message = "not upgrade" 
dxDrawRectangle (posX*2+300,posY,250,100, tocolor (0,0,0,150)) 
dxDrawRectangle (posX*2+300,posY,250,Hvis, tocolor (255,255,255,150)) 
dxDrawText ("Upgrade",posX*2+300,-(vis)+50-(Hvis),sX,sY,tocolor (255,255,255,255),1.5,"default-bold", "center", "center") 
dxDrawText (message,posX*2+300,-(vis)+100-(Hvis),sX,sY,tocolor (255,255,255,255),2,"default-bold", "center", "center") 
 end 
 end 
 addEventHandler ("onClientRender",root, weaponBar) 

client side

[Dealman]

What event handler are you using for the server-side code you pasted? Are you sure source is returned as a player element?

[Chronic]

This should work.

triggerClientEvent ( "onUpgradeText", source, message ) 

[Dealman]

This should work.

triggerClientEvent ( "onUpgradeText", source, message ) 

bool triggerClientEvent ( [element sendTo=getRootElement()], string name, element theElement, [arguments...] ) 

First argument is the element to send it to.

[3HAXAPb94]

so what i need to do?

[Castillo]

triggerClientEvent ( source, "onUpgradeText", source, message ) 

[Chronic]

Trust me, this will work. I tried doing that on my other scripts, but didn't work.

triggerClientEvent ( "onUpgradeText", source, message ) 

[Castillo]

That'll trigger to everyone, not just to 'source'.

[Chronic]

Oh, sorry didn't see your post when I said it. Anyway thanks for telling me!

[3HAXAPb94]

Guys, but it still not work. Maybe in client somethink bugged?

[Castillo]

Post both client and server side scripts.

[3HAXAPb94]

--Client 
addEvent ("onUpgradeText",true) 
addEventHandler ("onUpgradeText",root,weaponBar) 
 function weaponBar(message) 
 if not message then 
 message = "not upgrade" 
dxDrawRectangle (posX*2+300,posY,250,100, tocolor (0,0,0,150)) 
dxDrawRectangle (posX*2+300,posY,250,Hvis, tocolor (255,255,255,150)) 
dxDrawText ("Upgrade",posX*2+300,-(vis)+50-(Hvis),sX,sY,tocolor (255,255,255,255),1.5,"default-bold", "center", "center") 
dxDrawText (message,posX*2+300,-(vis)+100-(Hvis),sX,sY,tocolor (255,255,255,255),2,"default-bold", "center", "center") 
 end 
 end 
 addEventHandler ("onClientRender",root, weaponBar) 

--server 
local luck = math.random(1,5) 
if luck == 1 then 
outputChatBox ("barrel ") 
message = "Barrel" 
triggerClientEvent ( source, "onUpgradeText", source, message ) 
giveMeBarrel () 
elseif luck == 2 then 
message = "Aura" 
triggerClientEvent ( source, "onUpgradeText", source, message ) 
outputChatBox ("you gived AURA(6 sec)") 
giveMeAura() 
elseif luck ==3 then 
message = "Fix" 
triggerClientEvent ( source, "onUpgradeText", source, message ) 
outputChatBox ("you vehicle fixed") 
fixVehicle ()  
elseif luck == 4 then 
message = "Nitro" 
triggerClientEvent ( source, "onUpgradeText", source, message ) 
outputChatBox ("nitro") 
nitro () 
elseif luck == 5 then 
message = "Rocket" 
triggerClientEvent ( source, "onUpgradeText", source, message ) 
outputChatBox (" rocket") 
doShoot() 
end 
  

[Castillo]

local message = "" 
  
addEvent ( "onUpgradeText", true ) 
addEventHandler ( "onUpgradeText", root, 
    function ( msg ) 
        removeEventHandler ( "onClientRender", root, weaponBar ) 
        message = msg 
        addEventHandler ( "onClientRender", root, weaponBar ) 
    end 
) 
  
function weaponBar ( ) 
    dxDrawRectangle (posX*2+300,posY,250,100, tocolor (0,0,0,150)) 
    dxDrawRectangle (posX*2+300,posY,250,Hvis, tocolor (255,255,255,150)) 
    dxDrawText ("Upgrade",posX*2+300,-(vis)+50-(Hvis),sX,sY,tocolor (255,255,255,255),1.5,"default-bold", "center", "center") 
    dxDrawText (message,posX*2+300,-(vis)+100-(Hvis),sX,sY,tocolor (255,255,255,255),2,"default-bold", "center", "center") 
end 

I'm assuming that you have 'posX', 'posY', 'Hvis', 'vis' variables defined already?

[3HAXAPb94]

Thanks Solidsnake now Its work =)

"I'm assuming that you have 'posX', 'posY', 'Hvis', 'vis' variables defined already?"

yes

[Dealman]

so what i need to do?

As I said, what event are you using for your server-side function? 'Cause you didn't post the entire part of that function. Are you sure that source is returning a player element and not something else?
