dxDrawText alpha animation

[xTravax]

hello!

i wanted to ask something

how can i make some dx text dissapear after 6 seconds with animation of fading out(alpha decreasing-fourth argument i believe) ?

[WASSIm.]

you can use:

interpolateBetween

i tried reading the wiki about it but i dont understand how to do this with: vector?

any example please?

You can just simply use a variable to define the alpha and do alpha = alpha +/- 1

i am really sorry i am a total noob in this,i tried to make it but it just draws the text and doesnt decrease alpha at all because my code is wrong,feel free to laugh

screenWidth,screenHeight = guiGetScreenSize() 
function someFunction() 
local alpha = 255 
if (alpha) then 
dxDrawText ( "TEST", screenWidth/2, screenHeight/2, screenWidth, screenHeight, tocolor ( 255, 255, 255, alpha ), 1, "bankgothic" ) 
alpha = alpha - 1 
end 
end 
addCommandHandler("dx",someFunction) 
  
  
function HandleTheRendering ( ) 
    addEventHandler ( "onClientRender", root, someFunction ) -- keep the text visible with onClientRender. 
end 
addEventHandler ( "onClientResourceStart", resourceRoot, HandleTheRendering )

Don't make the variable local inside the function because the function is called every frame and every time it's called you assign 255 to the same variable. That is logical and alpha will be 255 every frame.

text still gets drawn before i even use the command, and alpha doesnt change at all

You can create a nice fadeIn and FadeOut effect using

getTickCount

local ScreenSizeX,ScreenSizeY = guiGetScreenSize(); 
local StartTick,Duration,EndTick = nil,5000,nil; 
local Debounce = false; 
local function RenderHandler() 
    local CurrentTick = getTickCount(); -- get the current tick; 
    local Progress = (CurrentTick-StartTick)/Duration; -- calculate the progress between 0 and 1 using simple math; 
    local Alpha = interpolateBetween(0,0,0,255,0,0,Progress,"InOutQuad"); 
    dxDrawText("This text is fading in...",ScreenSizeX/2,ScreenSizeY/2,ScreenSizeX,ScreenSizeY,tocolor(255,255,255,Alpha),1,"bankgothic"); 
    if CurrentTick>=EndTick then -- if the animation is finished; 
        StartTick,EndTick = nil,nil; -- clear variables; 
        removeEventHandler("onClientRender",root,RenderHandler); -- remove the render handler; 
        Debounce = false; -- we can now use /dx again; 
    end; 
end; 
addCommandHandler("dx",function() 
    if not Debounce then -- if the text isn't already rendering; 
        Debounce = true; 
        StartTick = getTickCount(); -- get the current tick as the start tick of the animation; 
        EndTick = StartTick+Duration; -- calculate the end tick; 
        addEventHandler("onClientRender",root,RenderHandler); -- add the render handler only when you type the command; 
    end; 
end); 
  

I have not tested it, but it should work.
