I Have 2 types of Sprite Renderer GameObjects that user can spawn and place in world

1. Window
2. Block

• blocks are basic elements
• windows act as containers for blocks so user can group together similar blocks

how can i do such that blocks outside window appear below any window and blocks that are part of window (placed inside window) appear above that window.

• 1 I suppose you would then go through the sortingOrder and calculate and update them accordingly whenever the user modifies the window groupings – derHugo Commented Mar 3 at 10:47

To draw a block above glass if it is a child, set the sorting order property based on whether the glass is a parent of the block. For instance it could be something as simple as (and it goes without saying that this is pseudocode so don't use it):

var child = transform.GetChild(0);
if (child && child.CompareTag("block")){
GetComponent<SpriteRenderer>().sortingOrder = -1;
}

You would place such a script on all glass objects and ensure that all block objects are tagged with "block".
