How do I change Collider Radius of other objects from script

Unity Engine

I want to change the Collider Radius of a set of same objects, but I want to do it from other script.
What I have tried is this :

GameObject.FindGameObjectWithTag(“InvisPoint”).GetComponent().radius = 1f;

my purpose is to change the collider size depending on camera size(orthographic camera)
So the colliders will have steady size with reference to the screen as I change camera size. Any ideas?

If you want the colliders to be the a size proportional to the camera, you just do it as such.

// this would make it 25% of the camera size all the time
float proportionalRadius = camera.orthographicSize * 0.25f
GameObject.FindGameObjectWithTag(“InvisPoint”).GetComponent().radius = proportionalRadius;

Is that what you are asking?
