Textdraw len bug - scottyishere - 25.12.2010

Hello.

I have a textdraw which updates when the player does something. The problem is, this TXD can reach 1000 strlen.

The bug is the fact that if the length passes the 280 string length, it crashes the client with error:

I may state that I use ~n~ to form some kind of list in the textdraw.

Any ideas?

Re: Textdraw len bug - kurta999 - 25.12.2010

Please post here you textdraw.

The 1024 is 'not the characters limit', this is problem.

I would love to post the txd but I don't want to make it public (hope you understand me). I can make an example.

pawn Код:

new str[1000];
format(str,1000,"   ~r~List~w~~n~~n~");
for(new x=0; x!=50;x++)
{
    format(str,sizeof(str),"%sRowBLABLABLABLABLABLABLA%d~n~",str,x);
}
TextDrawSetString(txd,str);
TextDrawShowForPlayer(txd);

I have done many tests and it seems that it crashes between 278 & 289 so it may be 280 the limit.

I hope this can be fixed.

Re: Textdraw len bug - Sascha - 25.12.2010

you could use something like this:

Код:

new str[1000];
format(str,1000,"   ~r~List~w~~n~~n~");
for(new x=0; x!=50;x++)
{
    format(str,sizeof(str),"%sRowBLABLABLABLABLABLABLA%d~n~",str,x);
}
if(strlen(str) <= 280){
TextDrawSetString(txd,str);
TextDrawShowForPlayer(txd);
}

this won't show the textdraw if it is too long... you can change the number to the length which is the highest possible for you..

Re: Textdraw len bug - Rac3r - 25.12.2010

50 ~n~ in one textdraw is asking for problems. I have no idea what the symbol limit is, but using it as much as you have will cause crashes.

Код:

if(strlen(str) <= 280){

You could also add better defence to this

Код:

if(strlen(str) <= 280)
{
    format(str, sizeof(str), " ");
}

It's a global textdraw, just split it into more textdraws. Make about 3 and position them so they all line up nicely.

Why do this if it's a nasty bug and it could be (easily i think) fixed by the dev team.

Btw it was just an example i only use 'n' 9 times and thats not the reason of the crash.

Re: Textdraw len bug - scottyishere - 26.12.2010

I'm just bumping this topic because this is a really serious issue.

(has not been fixed in RC7 - atleast it's not written in the changelog)

EDIT: Confirmed, it's still crashing the client if TXD len passes 280.

Re: Textdraw len bug - Rainmaker - 26.12.2010

Do you use any color tags ? Its a known bug, that color tags used before 255 sign in TD string longer than 255 crash.

No ~r~ ~g~ ~b~ ~p~ etc. ?

Re: Textdraw len bug - scottyishere - 26.12.2010

Yes I do use colors and I really need them.

Indeed it's a bug and it NEEDS a urgent fix. It will be deeply appreciated.

Re: Textdraw len bug - Rainmaker - 26.12.2010

Ok Dont use color tags. Thats it, problem solved.

I already discussed this with Kalcor during 0.3a development and he cant find out solution for this. Its hardcoded limitation in San Andreas. Nothing has to be fixed and if you don't like it, code MP yourself and make it better.
