while( condition ) loop
| • | condition | – | If this executes as true then loop is executed. | |
| • | loop | – | Can be either a single statement, a block statement, or a null statement. |
Any of the statements can be null statements.
Specification
| Type | Condition |
|---|---|
| integer | True if it is not zero. |
| float | True if it is not zero.[1] |
| string | True if its length is not zero. |
| key | True only if it is a valid key and not NULL_KEY. |
| vector | True if the vector is not ZERO_VECTOR. |
| rotation | True if the rotation is not ZERO_ROTATION. |
| list | True if the length is not zero. Note that correct behavior is only seen with Mono-compiled scripts; LSO-compiled scripts incorrectly resolve to false if the list is non-empty: BUG-230728 |
Examples
//single statement
integer a = 0;
integer b = 10;
while(a < b)
llOwnerSay((string)(a++));
//block statement
integer a = 0;
integer b = 10;
while(a < b)
{
llOwnerSay((string)a);
++a;
}
//null statement
integer a = 0;
integer b = 10;
while(a++ < b);
