Finding array of current state game objects

[SpyderMike002]

If I have 20 of the same game object in the scene but it can be in different states, what is the best way to find objects based on the current state?

For example my current stat is something like:
I have 20 game objects named “business” and each business maybe be a type (10 options) and either running or not running.

Right now I have the business change its tag to “lumbermill is running” and on my character I findgameobjectwithtag to create an array of all of the current lumbermills that are running.

This method is working but as I keep increasing the business types I’m dealing with alot of tags. I really don’t want to make each one an individual game object. Is there a better way?

Make a MonoBehaviour to identify them and use FindObjectsOfType() to find them all.

Ideally only use that finder function once, at start of level, or perhaps when you know one was added / removed, eg, ideally not every single Update() loop.

You could also do it with an interface, which you would implement in a MonoBehaviours.

How can I detect/catch the SendMessageOptions.RequireReceiver error message?

SendMessage is kind of antiquated. The way to do things today is to make an interface. That way you say “is there this interface?” and check if it’s not null, then call the method you want if it is. Don’t be afraid, it’s pretty simple, and it’s way more powerful. Here, soooper-quickly: // stick this in its own file, usually IMyInterface.cs public interface IMyInterface { void MyMethod( int arg1, string arg2); } Now, in whatever Monobehaviors you have, you implement that interface, which ba…

Looks reasonable... you might get some benefit by extracting common methods into some kind of interface, which is a pattern that works really well with Unity and MonoBehaviors. MBs can then implement specific interfaces and be found because they implement those interfaces. For instance, you might have an IAttackable interface that can represent a target that can be attacked. Some of its methods might be "what can hurt you?" and "you have been attacked by ..." This also means when a projectile …
