Question How Can I Keep an Object Inside a Bounding Box While Rotating the Camera Around It?

Please see the attached image for better details on what I'm trying to achieve.
I have a camera that can rotate around a target object, but I want it to keep the object with a screen space bounding box by moving back and forth.

I'm pretty new at C# and not sure how to achieve this, any help or guidance would be greatly appreciated!

 

Camera stuff is pretty tricky... you may wish to consider using Cinemachine from the Unity Package Manager.

There's even a dedicated forum: https://forum.unity.com/forums/cinemachine.136/

 

I agree with @Kurt-Dekker, just use Cinemachine, there are a ton of tutorials on it on YouTube, and it achieves exactly what you need very easily.

Now if still want to do it manually via calculations, you need to calculate the frustrum size: https://docs.unity3d.com/Manual/FrustumSizeAtDistance.html

Thank you for this suggestion. I know how to do a simple raycast to check distance, but how can I raycast the perimeter of an object?

 

Thank you. This is a new concept to me but it seems like the right direction. I'll look into it.
