Half scenes with static elements, other with spawn

Question

I have 2D game, where half scene with spawn enemies and (for example) other half scene, where I want use static enemies and other elements.

I thought to create sript that after some time (for example 10 seconds), will stop spawn scripts , and run the movement of other elements.

So. Maybe there is a reasonable solution to this problem.

[UPDATE]

I need the most sensible solution of such a problem, I do not mean to do this, but how to make it better.

1) Can make static elements, which will be a certain time, just stand behind the camera, and then move ... or programmatically create static elements, over time, in advance of known locations...Or download the entire stack of elements over time.

2) Or can completely abandon this idea. A striking example is the Subway Surf, there static scenes (layout) are created in random order.

P.s. I hope I have explained my problem

Answer 1

Just learn to use "Invoke", it's extremely simple.

Invoke( "YourOtherRoutine", 10f );

So after ten seconds it will run the other routine. That routine could easily stop one script running, start another script running, or, whatever it is you want to do. There are tens of thousands of examples of Invoke() and InvokeRepeating() on the usual Unity forums, etc.
