Trouble With Strlen()
 

im sorry i havent posted code in a while..
plz help meh X_x



if (created) {
timeout=0.05;
}
if (timeout) {
timeout=0.05;
setstring message2,This is NOT a Test;
showimg 2,@@b@#s(client.message2),screenwidth-strlen(message2)*8,screenheight-21;
changeimgvis 2,4;
}

I need it to be kinda like the little thing on GK that says you know "you avatar of govannon atmoizes Glok Lord"

1) Strlen takes a string, not the name of a string. Currently it's returning the length of 'message2'.
2) Use a this.string for temp stuff.

what would i use to get the length of "this is NOT a test" then?

Use a for loop. What you need to do is get the strlen of the string's value (this is NOT a test), not just the length of the string name.

a for loop?

how would the script look then?

I don't know why protagonist is talking about loops. Anyway:

#s() converts string names into strings.

Everybody always tells me to do for loops :(.


I would do something like for(i=0;i<strlen(#s(message2));i++) type thing.

...for what purpose?

X_x

strlen(#s(client.message2))

would be the length of "this is NOT a test" then?

strlen(#s(message2))

woo! alright i got it working now... i feel good now that stefan posted in my thread thanks for the help guys

Ugh, sorry, that would just give i the the value of the length of message2.

Whoa, you are awake late.:megaeek:

yea stefan's crazy like that...



now i gotta figure out the right number to multiply it by.. X_x

and i think capital letters will screw that up
Edit : Yep... having lower case letters numbers and capital letters changes everything... now im gonna have to check the string for caps, numbers, and lowercase letters X_x

Uh. Do you even know what you're talking about?

Do you even know what the guy's trying to do?

He's trying to use strlen to return a value.

Using a for loop does not help him learn to use strlen.

And the fact that everyone else tells you to do for loops has absolutely nothing to do with this situation. Sorry, just had to complain about that.

Anyway, as for your problem wonderboy, align your showimg text to the right instead of the left perhaps? Then you need not worry about strlen at all, really.

omg i can just Align it?????

Well, that was mean, I already admitted my mistake.
I was thinking about sarraylen, not strlen.

To the very best of my knowledge, yes. It requires putting a letter in between the @ signs of the showimg, and I believe is explained in one of the newfeatures.txts (though I may be wrong about it being in there- it's been a while since I looked for image-showing clarifications). As it happens, I haven't had an occasion to align something to the right, so I do not know the letter off the top of my head (although, the logical guess is r). If you can't find it, I'll have access to my other computer in a couple of hours, and can find it then.

Perhaps it was mean, but he was trying to learn, and you were giving him incorrect information. Naturally, I will be very critical of cases like that, because when people are trying to learn, receive incorrect information, and it is not corrected, they not only learn wrong, but in some cases their own ignorance will prevent them from ever learning their way is wrong. I dealt with a case like this recently, in which a scripter not only refused to acknowledge something stefan had explained about triggeractions, but deleted a script of several hours work, as well as a few weeks' worth of that script's running and logging. :\

Yes, I didn't have the right command. But Kaimetsu pointed it out already, and I made it clear I was mistaken.

If you look in newfeatures2003.txt you will notice there is a nice new handy variable added called textwidth :)
so instead of using strlen() I would suggest using textwidth

NPC Code:

---

textwidth(size,font,style,text)

---

Makes things easier and more accurate than guessing a formula to get the width of your text

---Kain Morbid

:confused: umm... i dont think anyone has really helped solved my problem...

Ask Tseng,he is the best scripter of the world. ^_^

NPC Code:

---

if (created) {

  timeout=.05;

}

if (timeout) {

  timeout=.05;

  setstring message2,This is NOT a Test;

  showimg 2,@@b@#s(client.message2),screenwidth-strlen(#s(message2))*8,screenheight-21;

  changeimgvis 2,4;

}

---

I have bolded what you forgot in your script.
though I do suggest using text width instead of strlen()*8 seeing as how textwidth is MUCH more accurate.

---Kain Morbid

yea kain i had gotten that part figured out but it turns out that *8 only works when each letter in message2 is lower case... numbers and CAPS screw up the placement.. which is why i want to know what tseng was talking about when he said i can probably align things to the right

It doesn't work at all when the font is not monospaced. Anyway:

Firstly, use showtext instead of showimg. Secondly, use an 'r' in the style argument. If you don't understand, read newfeatures.txt.

alright thanks kai
i used showimg because im just more used to showimg @@@ but yea ok show text and r in style arguement all so simple ^_^

lol, showtext, I can't stand that!
sarraylen() needs a for loop why? Sarraylen you don't need #s for, and it checks the amount of arrays in it rather than it's length x-x

¬_¬

cmon kai you cant deny that after using showimg @@@ for a while, it's hard to switch over to a new command

Uh, no it isn't. I never used showimg to display text after showtext was released.
