Not to be confused with llStringTrim.
this function will trim a string if it is too long.
Function <lsl> string StringTruncate(string text, integer length) {
if (length < llStringLength(text)) return llGetSubString(text, 0, length - 2) + "…";
// else return text;
} </lsl>
Example <lsl> string StringTruncate(string text, integer length) {
if (length < llStringLength(text)) return llGetSubString(text, 0, length - 2) + "…";
// else return text;
}
default {
state_entry() { // llSay(PUBLIC_CHANNEL, "Hello, Avatar!"); } touch_start(integer num_detected) { llSay(PUBLIC_CHANNEL, StringTruncate("my name Ulrik Ulrik", 11)); }
} </lsl> simpler code You don't need a user function for this exercise, as you can just use llGetSubString(). If you request a length longer longer than the string actually is, it will return the full string. (Omei Qunhua) <lsl> default {
state_entry() { string text = "abcdefghijklmnopqrstuvwxyz"; llSay(0, "<" + llGetSubString(text, 0 , 33) + ">" ); // outputs <abcdefghijklmnopqrstuvwxyz> llSay(0, "<" + llGetSubString(text, 0, 9) + ">" ); // outputs <abcdefghij> }
} </lsl>
