Description

Suspends the coroutine execution until the supplied delegate evaluates to true.

WaitUntil can only be used with a yield statement in coroutines.

Supplied delegate will be executed each frame after script MonoBehaviour.Update and before MonoBehaviour.LateUpdate. When the delegate finally evaluates to true, the coroutine will proceed with its execution.
