additional variables to addEventHandler

[Elohim]

Hello, i want to do an function that triggers other dx function, like this:

local sw,sh = guiGetScreenSize() 
function draw(splashpath,name,text) 
  if (splashpath) and (name) and (text) then 
dg =  dxDrawImage(sw*.1,sh*.65,sw*.900,sh*.600,"tt.png") 
nm =  dxDrawText(name,sw*.3,sh*.85) 
spl = dxDrawImage(sw*.12,sh*.72,sw*.200,sh*.400,splashpath) 
txt =  dxDrawText(text,sw*.29,sh*.90) 
else 
  outputDebugScript("Incorrect Syntaxis: drawDialogue(splashartpath,name,text)") 
end 
end 
--This triggers the function in top 
function drawDialogue(splashpath,name,text) 
  addEventHandler("onClientRender",getLocalPlayer(),draw) 
end 

i dont know how to add the arguments splashpath,name, and text into the eventHandler

Just make them global variables I guess.

Then the drawDialogue function would not just start the rendering but also do the checks and set the values.

[Elohim]

Oh, ok, and what is the best way to render that? "onClientRender"?

Edit: sorry, i cant get it to work, how can i do correctly the global variables? only add the _ ?

[Bonsai]

They best way would probably be to put them the same way as you put the "local sw,sh" variables.

They are available in the whole script file, as long as they are outside of a function.

Without the "local" they would be available in every script file e.g. all client-side scripts, of the resource.

I did this

local sw,sh = guiGetScreenSize() 
local spacer = dxGetFontHeight(1.2,"default") 
local nm = nm 
local spl = spl 
local txt = txt 
function draw(splashpath,name,text) 
  if (splashpath) and (name) and (text) then 
dg =  dxDrawImage(sw*.1,sh*.65,sw*.900,sh*.600,"tt.png") 
nm =  dxDrawText(name,sw*.3,sh*.85) 
spl = dxDrawImage(sw*.12,sh*.72,sw*.200,sh*.400,splashpath) 
txt =  dxDrawText(text,sw*.29,sh*.90+spacer) 
else 
  outputDebugScript("Incorrect Syntaxis: drawDialogue(splashartpath,name,text)") 
end 
end 
  
function drawDialogue(splashpath,name,text) 
  local nm = "bartender" 
  local spl = "bartender.png" 
  local txt = "test" 
  addEventHandler("onClientRender",getLocalPlayer(),draw) 
end 

didnt work, i think i did a mistake anywhere, or everywhere u.u

21 line replace getLocalPlayer() with root.

Also 13 line replace outputDebugScript with outputDebugString

You might need to go through the basics again.

Those dx functions don't return anything useful.

local nm = nm 

That seems kinda wrong too.

And the rest.. remove the if else from the render function and put that in the other one for the start.

local sw,sh = guiGetScreenSize() 
local spacer = dxGetFontHeight(1.2,"default") 
function draw(splashpath,name,text) 
local dg =  dxDrawImage(sw*.1,sh*.65,sw*.900,sh*.600,"tt.png") 
local nm =  dxDrawText(name,sw*.3,sh*.85) 
local spl = dxDrawImage(sw*.12,sh*.72,sw*.200,sh*.400,splashpath) 
local txt =  dxDrawText(text,sw*.29,sh*.90+spacer) 
end 
  
function drawDialogue(splashpath,name,text) 
  local nm = "bartender" 
  local spl = "bartender.png" 
  local txt = "test" 
  addEventHandler("onClientRender",root,draw) 
end 
  
drawDialogue("bartender.png","bartender","testing the shoots") 
  
  
  

i removed the locals on top, and repaired the errors that anubhav wrote, but i still cant add the variables to the event

[Anubhav]

  
local sw,sh = guiGetScreenSize() 
local spacer = dxGetFontHeight(1.2,"default") 
local name = "" 
local splashpath = "" 
local text = "" 
  
function draw(splashpath,text) 
    local dg =  dxDrawImage(sw*.1,sh*.65,sw*.900,sh*.600,"tt.png") 
    local nm =  dxDrawText(name,sw*.3,sh*.85) 
    local spl = dxDrawImage(sw*.12,sh*.72,sw*.200,sh*.400,splashpath) 
    local txt =  dxDrawText(text,sw*.29,sh*.90+spacer) 
end 
  
function drawDialogue(splashpath,name,text) 
    name = "bartender" 
    splashpath = "bartender.png" 
    text = "test" 
     
    addEventHandler("onClientRender",root,draw) 
end 
  
drawDialogue("bartender.png","bartender","testing the shoots")

dont work, "Expected string at argument 1" "Expected material at argument 6 " and "Expected string at argument 1"

[Anubhav]

  
local sw,sh = guiGetScreenSize() 
local spacer = dxGetFontHeight(1.2,"default") 
local name = "" 
local splashpath = "" 
local text = "" 
  
function draw() 
    local dg =  dxDrawImage(sw*.1,sh*.65,sw*.900,sh*.600,"tt.png") 
    local nm =  dxDrawText(name,sw*.3,sh*.85) 
    local spl = dxDrawImage(sw*.12,sh*.72,sw*.200,sh*.400,splashpath) 
    local txt =  dxDrawText(text,sw*.29,sh*.90+spacer) 
end 
  
function drawDialogue(splashpath,name,text) 
    name = "bartender" 
    splashpath = "bartender.png" 
    text = "test" 
  
    addEventHandler("onClientRender",root,draw) 
end 
  
drawDialogue("bartender.png","bartender","testing the shoots")

Returns error loading dxDrawImage on line 10. sorry if i cause troubles.

[Gravestone]

Line 10:

    local nm =  dxDrawText(name,sw*.3,sh*.85) 

I don't see any image path or function which should draw the image. Send us a screenshot of your debug script mode 3, that'll be helpful I guess.

First of all

Add 0 before every . (In the dxDraw functions)
