Hey all, I was trying to make it so that when I type in a word or two, XY Text takes that word and centers it. For example, if I were to type in 'pie', it would normally show up as |pie |. But I want it to do something like this: | pie |. I started to work on this code:
string word;
integer length;
integer free_spaces;
default
{
state_entry()
{
word = "Hello!";
length = llStringLength(word);
free_spaces = 10 - length;
llSay(0, (string)free_spaces);
}
}
All this would tell me how many free spaces there are. But I need to know how to add a space to the beginning or the end of the word. If someone can help me, that'd be great.

I'm sure, someone will come up with a much more clever idea  I did it like this:
string word;
integer length;
integer free_spaces;
integer total_chars = 10; // Total chars in your XY-Text
default
{
state_entry()
{
word = "Hello!";
length = llStringLength(word);
free_spaces = (total_chars - length)/2;
integer i;
for(i=0;i<free_spaces;i++){
word = " " + word + " ";
}
// Now, free spaces/2 might be a float, e.g. 5/2 = 2.5, so we'd have to add an extra space on one side
if((free_spaces * 2) + length < total_chars)
word += " ";
llSay(0, (string)free_spaces);
}
}
didn't test this inworld, though... hope there aren't any typos |

string word;
string spaces = " ";
default
{
state_entry()
{
word = "hi!";
integer a = 10 - llStringLength(word);
integer b = a/2;
word = llGetSubString(spaces,1,b) + word + llGetSubString(spaces,1,a-b);
//For odd numbered strings, the extra space will be at the end
//Just reverse b & a-b if you want it the opposite way
llOwnerSay(word);
}
}

I was just wondering how Jesse's script should work... tried in inworld and didn't get the expected result... ... until I figured, that I don't have greasemonkey working with safari, so HTML renders multiple spaces just as one... If someone else is having the same problem, the trick is to make the space string 10 long(or whatever length your XY-Text is). With x's this would look like: string spaces = "xxxxxxxxxx" Then, Jesse's solution is - as expected - way smoother than mine |

grrrrrr! Always forget that LL STILL hasn't fixed the forums. Easiest thing to do is hit the QOUTE button and the code is formatted correctly there. And also, you only need 5(oops! You need 6 spaces) spaces in the string. From: Haruki Watanabe Then, Jesse's solution is - as expected - way smoother than mine Been buggin me all afternoon, should still be a better way.

*lol* yeah - we're all waiting for the BBCode to come back... what about:
// I use x's here instead of spaces. Use as many spaces as your XY-Text has chars
string space = "xxxxxxxxxx";
string word = "hi!";
integer wordLength = llGetStringLength(word);
integer spaceLength = llGetStringLength(space);
// if the extra space should be added at the end, use this
integer pos = (spaceLength - wordLength)/2;
// if the extra space should be added at the beginning, use this
integer pos = llCeil((spaceLength - wordLength)/2);
word = llInsertString(llGetSubString(space, 0, wordLength - 1), pos, word);
// you could wrap that up into one command (which makes it less readable, though)
word = llInsertString(llGetSubString(space, 0, wordLength - 1), (spaceLength - wordLength)/2, word);
man - it's very early and I didn't have any sleep yet - don't even know if this is working |
