How can i hide weapon behind character sprite while he is looking up?(Top-down shooter)

Question

I'm brand new to unity and trying to learn it making little project that contains everything i have learnt. I really enjoy top-down shooters like Enter the Gungeon and i decided to take it as basis for my test project. I have already made character controller and weapon facing the mouse position and now i want weapon sprite to change an order in sorting layer when my character is looking up to hide the weapon behind character sprite. alt text

I have this very handsome orange square and was trying to do the same thing with my current knowledge using SpriteRenderer.sortingOrder in if statement with .transform.rotation.z but it doesn't work for some reason.

 if (gunTransform.rotation.z < 150f && gunTransform.rotation.z > 32f)
         {
             gunSpriteRenderer.sortingOrder = 0;
         }
         else
         {
             gunSpriteRenderer.sortingOrder = 2;
         }

Please show me what goes wrong here or suggest another solution of my problem. I will be very grateful.)

That is because gunTransform.rotation.z returns values between -1 and +1. What you want to use is gunTransform.eulerAngles.z, which returns values from 0 to 360. To see this in action, you can use a Debug-Message, like so:

 float angle = gunTransform.eulerAngles.z;
 
 Debug.Log(angle);
 
 if (angle < 150f && angle > 32f)
 {
     gunSpriteRenderer.sortingOrder = 0;
 }
 else
 {
     gunSpriteRenderer.sortingOrder = 2;
 }

You can read more about rotation here: Transform.rotation.

Off-topic but maybe relevant / useful to you is that there it says: "To rotate a Transform, use Transform.Rotate, which uses Euler Angles.".

I had better check how does code works before using it by myself. Thank you, buddy, you helped a lot.
