[vJASS] String "%" and "|"

[overcold_ice]

there's something wrong with percent (%) . . .
and a little wrong for "|" . . .

i tried to do something like this:

local string s = "!@#$%^&*()|"
call BJDebugMsg(SubString(s, udg_int, udg_int + 1))

//  if udg_int = 4
//  the result should show a "%"
//  but it doesn't, it shows the next character instead (^)

//  if udg_int = 10
//  the result shows a "|"
//  but i tried that for many characters at once,
//  and it turned out to be . . .
//  1. first "|" will be shown just normally
//  2. next "|" will be hidden
//  3. next "|" will be shown
//  4. next "|" will be hidden
//  5. . . . . .

for percent (%), it can be fixed by typing the percent twice (%%)
"%%" = "%"
for "|", can't be fixed, but can be evaded by typing "|" twice (||)
// to avoid some bugs of "|" (only for game message i guess)
/* change */ "|" /* to */ "||"

There's nothing wrong, it's just the way strings work in wc3. In most programming languages, strigns such as \n denote "newline", while % and| can ofcourse have other meanings. This is why you have to type the backslash twice when you use model paths in jass.

whatever you say, when i tested that,
it turns out to be like that . . .

local string s = "!@#$\%^&*()\|"

% is a placeholder for variables and the following letter indicates the format.

call DisplayTimedTextFromPlayer(Player(2), 0., 0., 10., "%s")

This will write the third player's name (as string) because the function sets this variable for the passed string.

| is for color codes, although there are only |c and |r.

Ok, I just tested that and that's not the case. "%s" displays "%s", not whatever the value of var s is.


Not sure what overloard_ice is on about..


btw, SubString(4, 5) would indeed ^.


Learn how substrings work bro ;p

%x will only work with DisplayTextFromPlayer, not DisplayTextToPlayer.

 

[Nestharus]

I used DisplayTimedTextToPlayer in my test, and %x displayed perfectly.

 

[Troll-Brain]

Read me again maybe ?

For sure %s is a valid argument, i don't know either ones.

EDIT : Ofc i mean that %s will be translated to the player name with DisplayTextFromPlayer but won't be remplaced with DisplayTextToPlayer.

 

[Nestharus]

But who uses DisplayTextFromPlayer anyways? lol

 

[Troll-Brain]

I do, with a valid player for debug messages, since it doesn't bug on replays (GetLocalPlayer bug on replays), or generally to display a text for all players.

Attention! The % symbol will lead the World Editor to strange behaviour if used in the Custom Script section.

[overcold_ice]

well . . .
it's strange . . . . . .
but i think this is really happened to me
(at least to me only)

and how about that "|" prob?
it's right, isn't it?

 

[Nestharus]

| is a blizzard specific escape character, so you need to escape it with \.

 

[overcold_ice]

have you tested that ?_?

 

[Nestharus]

The | is common knowledge... it's like \ for blizzard...

 

[overcold_ice]

that can't be done (\| = error)

 

[Nestharus]

Use ||

| is a special escape character by blizzard, so | escapes | just like \ escapes \.

\\ = \
|| = |

You can't use the two types of escape characters together, well you can ;o.
|\\ will work I believe (same idea as a\\)
\| will not work

| is sort of a pseudo escape character in that it only escapes characters that can be escaped... annoying as hell ;o.

For example, |f should display |f =).

 

[overcold_ice]

huh, misunderstood ~.~

it's the same idea as mine -_-

but that '%' thing is really happen . . . . @.@
