do loop while (condition);
• | loop | – | Executes once, then executes condition. | |
• | condition | – | If condition executes true, it then loops back and executes loop again. |
Any of the statements can be null statements. A do...while loop is slightly faster than a while or for loop, and requires fewer bytes of memory than a while or for loop.
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
//Counts from 1 to 5 default { state_entry() { integer olf; do llSay(0, (string) (++olf)); while(olf<5); } }
//Counts from 0 to 4 default { state_entry() { integer olf; do llSay(0, (string)olf); while((++olf)<5); } }
