Switches in Update question

Hello. I want to do something only once in Update(), and I'm using boolean switches to do so.
My question is: is there any better/elegant way to do so? Like not adding ton of bool variables ad hoc.

 

Without knowing what you want to do, it's impossible to tell you. Update runs every frame no matter what. Unless, you turn the gameobject or script off. But, if you are trying to check for a bool to become true, then run code and set it back to false, then you have to have the bool. Or, at least you have to have a conditional check to determine when that single execution must happen.

But again, without knowing what you want to do, it's impossible to offer real alternatives to your use case.

 

Show us your code, we could better assess your situation that way. Otherwise anything we say is just conjecture.

 

Thanks for reply. So, there is no universal alternative? That's is what I wanted to know.

 

if statements, switches, and branching in general are fundamental aspects of coding. If there was a universal replacement, they wouldn't be there.

As for your specific use case... we don't know, since we don't know your specific use case. Show us, even show an example, and maybe then we can.

But so far we only know "do something only once in update"... what does that even mean? If I wanted to do something only once, I wouldn't do it in Update, I would do it when it's called for (such as Start, Awake, OnCollisionEnter, whatever moment upon which the "once" is supposed to happen, etc).
