equalize different degrees

Without knowing more about your project it's hard to guess how it's all set up, but mathematically:

Since the direction of object2 is opposite to that of object1, first you need to reverse it:

Say object1 is 270 degrees, then 360-270=90.

Now you need to add the offset w$$anonymous$$ch is 90:

object2 degrees = 90-90 = 0

Say object1 is 45 degrees, then 360-45=315.

Now you need to add the offset w$$anonymous$$ch is 90:

object2 degrees = 315-90 = 225

That said, my answer is rather abstract, and I t$$anonymous$$nk @Defetysta 's answer is indeed the easiest and most pragmatic.

I t$$anonymous$$nk easiest solution would be to create empty GameObjects, make them parents of your objects and rotate them the same way around.
