wait a second before say path is valid?
hey folks! i want to set a bool to true as soon as a navmesh agent finds a valid path. this works fine but he sould wait some seconds before set the bool to true cause you might want to change something in the last seconds. currently it looks like this:
void CheckPath()
{
agent = GetComponent<NavMeshAgent>();
NavMeshPath path = new NavMeshPath();
agent.CalculatePath(target.position, path);
if (path.status == NavMeshPathStatus.PathComplete)
{
//wait 3 seconds
Path =true;
Debug.Log("PathComplete");
}
else
{
Path =false;
//set timer back to 3 seconds
Debug.Log("PathInvalid");
}
i know i could use some co routines or IEnumerator but i have no clue how i could use it in the sample above? can somebody help me please? thanks!
Change the void to a IEnumerator type:
//void CheckPatch() {
IEnumerator CheckPath() {
When you want a delay, instruct the coroutine to wait:
yield return new WaitForSeconds(3f);
Also instead of calling CheckPath() directly, it will need to be called with StartCoroutine()
StartCoroutine(CheckPath());
So the yield will count down from 3 on. And. What will happen when the path turns false again during this 3 seconds?

if....
StartCoroutine(WaitPath(3.0F));
...
IEnumerator WaitPath(float waitTime)
{
yield return new WaitForSeconds(waitTime);
Path =true;
}
