A little bit help here...

[GTX]

Hello, I changed topic, I need a help with getting alpha.

I'll explain:

I want to get alpha because I want to make dx text hidding smoothly, so:

  
function dxDrawColorText(str, ax, ay, bx, by, color, scale, font, alignX, alignY) 
  
  if alignX then 
    if alignX == "center" then 
      local w = dxGetTextWidth(str:gsub("#%x%x%x%x%x%x",""), scale, font) 
      ax = ax + (bx-ax)/2 - w/2 
    elseif alignX == "right" then 
      local w = dxGetTextWidth(str:gsub("#%x%x%x%x%x%x",""), scale, font) 
      ax = bx - w 
    end 
  end 
  
  if alignY then 
    if alignY == "center" then 
      local h = dxGetFontHeight(scale, font) 
      ay = ay + (by-ay)/2 - h/2 
    elseif alignY == "bottom" then 
      local h = dxGetFontHeight(scale, font) 
      ay = by - h 
    end 
  end 
  
  local pat = "(.-)#(%x%x%x%x%x%x)" 
  local s, e, cap, col = str:find(pat, 1) 
  local last = 1 
  while s do 
    if cap == "" and col then color = tocolor(tonumber("0x"..col:sub(1, 2)), tonumber("0x"..col:sub(3, 4)), tonumber("0x"..col:sub(5, 6)), tonumber("0x"..col:sub(7, 8))) end 
    if s ~= 1 or cap ~= "" then 
      local w = dxGetTextWidth(cap, scale, font) 
      dxDrawText(cap, ax, ay, ax + w, by, color, scale, font) 
      ax = ax + w 
      color = tocolor(tonumber("0x"..col:sub(1, 2)), tonumber("0x"..col:sub(3, 4)), tonumber("0x"..col:sub(5, 6)), tonumber("0x"..col:sub(7, 8))) 
    end 
    last = e + 1 
    s, e, cap, col = str:find(pat, last) 
  end 
  if last <= #str then 
    cap = str:sub(last) 
    local w = dxGetTextWidth(cap, scale, font) 
    dxDrawText(cap, ax, ay, ax + w, by, color, scale, font) 
  end 
end

You want to get alpha?

If you want to change the alpha of the text, just edit it in ' color ' - Wherever that is.. I can only see the argument.

You can't understand... I want to get alpha of the dx text, I need to change the line 28 and 33 at argument 4 in tocolor function. So, I need to get alpha, how?

[JR10]

There is no way to get the alpha of a dx text.

You need to have variable, which you will use in dxDrawText as the alpha argument.
