Suspends the coroutine execution for the given amount of seconds.
WaitForSeconds can only be used with an yield statement in coroutines.
function Start() {
// Prints 0
Debug.Log (Time.time);
// Waits 5 seconds
yield WaitForSeconds (5);
// Prints 5.0
Debug.Log (Time.time);
}You can both stack and chain coroutines.
The following example will execute Do but will continue after calling Do immediately:
function Start() {
Do();
Debug.Log ("This is printed immediately");
}
function Do() {
Debug.Log ("Do now");
yield WaitForSeconds (5); //Wait for 5 seconds
Debug.Log ("Do 5 seconds later");
}The following example will execute Do and wait until it is finished before continuing its own execution:
//Chain Coroutine
function Start() {
//The below line is similar to the yield Do(); only if you are using Unity JavaScript. However, if you use C#, you must use StartCoroutine. (For more details in the Appendix C)
yield StartCoroutine(Do());
Debug.Log ("This is printed after 5 seconds");
Debug.Log ("This is after the Do coroutine has finished execution");
}
function Do() {
Debug.Log ("Do now");
yield WaitForSeconds (5); //Wait for 5 seconds
Debug.Log ("Do 5 seconds later");
}
