Wait_For_Event( num_seconds_timeout ) | |
---|---|
Parameters: | |
Name | Type |
num_seconds_timeout | Integer |
Explanation | |
The primary access to a script's event queue. If there is an event waiting, the function immediately returns with the event (could be a string, int, struct, etc). | |
If no event is waiting, the script sleeps for num_seconds_timeout or until a new event arrives. If the timeout is reached, the function returns 0. | |
if timeout is 0, returns immediately | |
Return values | |
object on event recv, 0 on timeout |
