dxDrawText

[Lloyd Logan]

Why does this instantly delete the text?

function drawText() 
        dxDrawText("You have successfully bought a vehicle!", 92, 158, 720, 195, tocolor(65, 205, 4, 255), 1.40, "pricedown", "left", "top", false, false, true, false, false) 
        setTimer ( function() 
        triggerEvent("destroy") 
    end, 5000, 1 ) 
    end 
addEvent("drawSuccess", true) 
addEventHandler("drawSuccess", root, drawText) 
  
  
function destroyText() 
    removeEventHandler("drawSuccess", getRootElement(), drawText) 
end 
addEvent("destroy", true) 
addEventHandler("destroy", root, destroyText)

What do you mean?

[Lloyd Logan]

What do you mean?

As soon as the it draws the text, it disappears almost extremely quickly (like .5 seconds).

dxDraw functions are only drawn for ONE frame, thus needing to work in conjunction with an event such as onClientRender or onClientPreRender in order to draw them every frame.

Ah, I understand! So how would I trigger them (not using the render?)

[Castillo]

You can't use dxDrawText without onClientRender/onClientPreRender/onClientHUDRender.

You can't use dxDrawText without onClientRender/onClientPreRender/onClientHUDRender.

So how could I trigger it at a specific time?

[Castillo]

You add the event handler to render it.

[Lloyd Logan]

You add the event handler to render it.

But if I were to do onClientRender wouldn't it show as soon as the player joins? Instead of when I trigger it?

[Castillo]

If you add the event only when you need to, then no.

[WASSIm.]

you can make like this

function drawText() -- draw text 
        dxDrawText("You have successfully bought a vehicle!", 92, 158, 720, 195, tocolor(65, 205, 4, 255), 1.40, "pricedown", "left", "top", false, false, true, false, false) 
addEventHandler("onClientRender", root, drawText) 
  
 setTimer (removeEventHandler, 5000, 1, "onClientRender", getRootElement(), drawText) -- remove text 

OR

use Textdisplay

If you add the event only when you need to, then no.

Wait so I don't need to use addEventHandler within a function until I want to?

[Castillo]

Well, I thought that was obvious.

Well, I thought that was obvious.

I never thought of it to be honest! Thanks!

function renderMyText ( ) 
    dxDrawText ( arguments ) 
end 
  
addCommandHandler ( "render", 
    function ( ) 
        addEventHandler ( "onClientRender", root, renderMyText ) -- Begin rendering our text  
    end 
) 
  
addCommandHandler ( "stoprender", 
    function ( ) 
        removeEventHandler ( "onClientRender", root, renderMyText ) -- Stop rendering our text  
    end 
) 

That's an example.

function renderMyText ( ) 
    dxDrawText ( arguments ) 
end 
  
addCommandHandler ( "render", 
    function ( ) 
        addEventHandler ( "onClientRender", root, renderMyText ) -- Begin rendering our text  
    end 
) 
  
addCommandHandler ( "stoprender", 
    function ( ) 
        removeEventHandler ( "onClientRender", root, renderMyText ) -- Stop rendering our text  
    end 
) 

That's an example.

Thank you! All is working.

Line 13: addEventHandler should be removeEventHandler to stop rendering the text.

Yeah, I only used his example as a guideline, so all is good, thanks though!

[Castillo]

My mistake, fixed.
