hello…
Apologies for the beginner question, but I’m stumped.
In extending the space shooter project I would like to introduce new coroutines I have added to the game. For example, when the Player reaches a certain score, one or more running coroutines will stop and one or more will start.
Additional when the Player Character has an OnTriggerEnter() collision with a particular Object with the ‘LevelSwtich’ script, one or several coroutines will stop and another will begin.
What I’d like to do is continually update a method called UpdateLevel() which resides in start(). Meaning I’ve placed the IENumerator coroutines within other methods, such as MainLevel(), that will be called or stopped within UpdateLevel() given certain conditions.
How do I do this?
THANKS!!!
