Just a question..

[Timic]

Hey,

im asking for dxText

well my question is

if i can make dxText with HEX color,

for example:

test = dxText:create('#ff0000Hey #ffffff._.', screenWidth - 88, 145, false, 'bankgothic', 1.5, 'right'),

he have to show like this on the screen Hey ._.

it is possible?

ty for reply

[dzek (varez)]

not possible in simple way.

you will need to write custom function that will be splitting text on every color code, then displaying few dx texts with various colors

I cant do it

[dzek (varez)]

i thought so. as you probably know - nobody is going to fulfill your request

[Timic]

i made it but it dont work

function justWords(str) 
  local t = {} 
  local function helper(word) table.insert(t, word) return "" end 
  if not str:gsub("%w+", helper):find"%S" then return t end 
end 
  
  
-- Direct X Drawing 
  
addEventHandler("onClientRender",root, 
     
function() 
         
dxDrawText("#ff0000TEST #00ff00CODE",958.0,16.0,1399.0,54.0,tocolor(255,255,255,255),1.0,"bankgothic","left","top",false,false,false) 
  
end)  
  
  

[dzek (varez)]

it have no sense at all o_O

[Timic]

how i fix it

[dzek (varez)]

i gave you some infos - you are just doing "random scripting".

just learn basics of lua, as you dont know even the most basic things as i can see..

[Aibo]

using the info posted by varez above i wrote a function for you:

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 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"..string.sub(col, 1, 2)), tonumber("0x"..string.sub(col, 3, 4)), tonumber("0x"..string.sub(col, 5, 6)), 255) 
    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 
  
-- example usage: 
  
testline = "testing: #ff0000red #00FF00green #0000ffblue blue #ff0000red again" 
addEventHandler("onClientRender", getRootElement(),  
function() 
  dxDrawColorText(testline, 100, 100, 900, 900, tocolor(255,255,255,255),1.0,"bankgothic")  
end) 

example result:

PS: maybe someone more experienced will optimize ('cause im not sure) this and/or add text alignment/line break support.

PS: variant for RGBA color codes with alpha:

function dxDrawColorAlphaText(str, ax, ay, bx, by, color, scale, font) 
  local pat = "(.-)#(%x%x%x%x%x%x%x%x)" 
  local s, e, cap, col = str:find(pat, 1) 
  local last = 1 
  while s do 
    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"..string.sub(col, 1, 2)), tonumber("0x"..string.sub(col, 3, 4)), tonumber("0x"..string.sub(col, 5, 6)), tonumber("0x"..string.sub(col, 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

add this please to wiki's Useful Functions and add it to See Also for dxDrawText

[Aibo]

i don't think i'm quite "eligible" to edit the wiki

[dzek (varez)]

why not? everyone can do it.

[Aibo]

i know that, it's just i'm not confident enough

[dzek (varez)]

i'll do it tommorow for you then i'll mark you as author

[Aibo]

ok, but i'm looking for a more efficient way to get tocolor() value (since it's a signed integer) from RGB, possibly without using tocolor().

according to wiki, dx function can use hex AARRGGBB format for color, and they do, problem is (when ive tried simply put hex color without all those tonumber()'s and stuff):

0xFFFF0000 -- is red

0xFF00FF00 -- is green

0xFF0000FF -- is black (?)

but

0x7F0000FF -- is blue (with half opacity)

something to do with signed integers messed up somewhere, or i'm dumb

[dzek (varez)]

lol, seems like something is broken indeed...

you could make some variables local (like: color, ax).

[Aibo]

since they are passed to the function the are local by default, or am i mistaken?

[Aibo]

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

To me, it looks like it's the Lua engine's issue with handling large numbers and that's been discovered. If you look at the example you posted:

FF0000FF == 4278190335

FF000100 == 4278190336 (it's just 1 more than it's supposed to be)

I had the same problem with saving player's bank balance in my bank resource. Lua is problematic at handling large numbers.

Thank you so much

[#Paper]

using the info posted by varez above i wrote a function for you:

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 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"..string.sub(col, 1, 2)), tonumber("0x"..string.sub(col, 3, 4)), tonumber("0x"..string.sub(col, 5, 6)), 255) 
    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 
  
-- example usage: 
  
testline = "testing: #ff0000red #00FF00green #0000ffblue blue #ff0000red again" 
addEventHandler("onClientRender", getRootElement(),  
function() 
  dxDrawColorText(testline, 100, 100, 900, 900, tocolor(255,255,255,255),1.0,"bankgothic")  
end)

ok ty, works, but it's white don't take the nick color <_<

testline = getPlayerName(player) 
dxDrawColorText(testline, sx, sy - offset, sx, sy - offset, tocolor(255,255,255,textalpha),0.4,"bankgothic") 

[Aibo]

does nick have color code in it at all?

[#Paper]

yes it have...

[Aibo]

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

[#Paper]

the output is the name whitout codes but white
