Center an object in Ortographic view

Questions & Answers
1

Hi, I have a complicated problem to solve:
I have a rectangular GameObject (a wall) that have to be centered inside an ortographic camera. It has to be zoomed in as much as possible but at the same time i need that he has a fixed padding from the sides of the screen (for example, from the wall at the edge of the screen there must always be a minimum of 60 px).
The width of the wall is variable and therefore the size parameter must be recalculated each time after the wall resizing.
I found this code to resize the wall height in order to fit the entire screen:

Camera.main.orthographicSize = target.renderer.bounds.extents.y;

I tried to modify the code as follows but did not get a proper solution:

public void changeOrthoSize () {
	GameObject wall = GameObject.FindGameObjectWithTag("Wall");
	float orthoSize;
	float rulerPadding = 60;
	if (wall.renderer.bounds.extents.x > wall.renderer.bounds.extents.y){
		// divide by 2 the x size to catch the y size
		if (wall.renderer.bounds.extents.x * 0.6f >= wall.renderer.bounds.extents.y){
			orthoSize = wall.renderer.bounds.extents.x * 0.6f + rulerPadding * 0.5f;
		} else {
			orthoSize = wall.renderer.bounds.extents.y + rulerPadding;
		}
	} else {
		orthoSize = wall.renderer.bounds.extents.y + rulerPadding;
	}
	Camera.main.orthographicSize = orthoSize;
}

Anyone have any suggestions for this problem?
Thanks in advance

You could try the following:

Cast a ray from the center of the object towards your camera (make it give you screen coordinates) and use this coordinate to center in on the screen.

Find the corners of the wall facing the camera, and cast a ray from them towards the camera. Change the camera’s FoV depending on wether the four corner coordinates are on the screen (you could also add/substract your padding pixels to each X and Y value).
