drawings secondary cameras in specifics places

Questions & Answers

I have the world coordinates and pixel size of a section of the screen that I want to draw a camera viewport over. Think minimap. I hand placed the normalized viewport rect for the designed aspect ration but need to support many different aspect ratios. since the rect for displaying a camera is normalized… a .25 width is different between different aspect ratios.

I cannot, for the life of me figure out how to get a specific world position and pixel height/width to convert to a normalized viewport that works in any aspect ratio. I only really need to adjust the width.

Here is what I have so far… totally doesn’t work

Camera miniCamera = GetComponent<Camera>();
		
Vector3 pos = Camera.main.WorldToScreenPoint( 
	new Vector3(myPosition.x - (myWidth/2f), 0f, 0f));
		
miniCamera .pixelRect= new Rect(pos.x, miniCamera.rect.y, imgSprite.width, imgSprite.height);

Solved it finally. Here is my solution. I got caught up on having to cast the Screen sizes to floats. :frowning:

Camera camera = GetComponent<Camera>();
		
Vector3 pos = Camera.main.WorldToViewportPoint(
	new Vector3(buttonSprite.transform.position.x - (imgSprite.width/2f),
	0f, 0f));

float scaledWidth = (Camera.main..orthographicSize*2f) * 
	((float)Screen.width / (float)Screen.height);
		
camera.rect = new Rect(
	pos.x,
	camera.rect.y,
	imgSprite.width/scaledWidth,
	camera.rect.height);
