Just a question..

Aibo · December 8, 2010

are you sure? and what is the output? white with color code or white with color code deleted?

the output is the name whitout codes but white

ok, my bad, function doesnt read the color value if string starts with it, update dxDrawColorText function:

function dxDrawColorText(str, ax, ay, bx, by, color, scale, font) 
  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)), 255) 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)), 255) 
    end 
    last = e + 1 
    s, e, cap, col = str:find(pat, last)

  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

in that case i dont know. as you can see — i've tested.

maybe you dont have a hex code in the name at all.

maybe something else, i cant see from here.

It's works, but it doesn't works just whit player's name...

DiSaMe · March 9, 2011

guess it has something to do with how Lua treat signed/unsigned 32bit integers, because:
string.format("%X", "0x7F0000FF") returns 7F0000FF

but

string.format("%X", "0xFF0000FF") returns FF000100

idk why, maybe some Lua pros will explain

This is not related to tocolor function. tocolor actually returns 32bit signed integer, so if the value is bigger than 0x7FFFFFFF, it's negative. Therefore if color value is 0x80000000 or more, you need to subtract 0x100000000 from it to get a value which dx functions can understand.

Can someone do it with centering compatible?

actually i've figured that out, and tried to subtract and all that, but it didnt work out as i recall. also: http://bugs.mtasa.com/view.php?id=5854

I'm trying to do it, but I fail

well it's enough to calculate from size of the resulting dx text and bounding box size. something like this:

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)), 255) 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)), 255) 
    end 
    last = e + 1 
    s, e, cap, col = str:find(pat, last)

  if last <= #str then 
    cap = str:sub(last)

Thank you!

Works great, only one more problem:

dxDrawText(cap, ax, ay, ax + w, by, color, scale, font, "left", "top", false, true)

Doesn't break the text to a new line..

well because line breaks are not supported there. that is what needs to be done

what is getPlayerName() at line 22? it need player element.

right now it returns false.

very strange, it seems it IS defined before.

probably i'm missing something obvious.

Aibo · May 16, 2011

function(player,name): and how do you plan to get player and name from onClientRender event?

use getPlayerName(getLocalPlayer()) (and you dont need to do it every frame)

but since you're stripping color tags, you dont need dxDrawColorText function anyway.
