Learn 2D layer sorting with Sorting Layer and Order in Layer.
Sprite Sorting and Layers
In 2D games, object depth is primarily managed through draw ordering rather than the Z axis. Sorting Layer establishes broader category layers (like Background, Foreground), while Order in Layer determines draw priority within that layer.
// Setting sorting layer and order via code
SpriteRenderer sr = GetComponent<SpriteRenderer>();
sr.sortingLayerName = "Characters";
sr.sortingOrder = 5;This guarantees that characters appear in front of backgrounds and behind foreground foliage.
Layer Ordering Logic
Layers render sequentially: The top-most Sorting Layer renders first at the back, while the bottom-most layer in the project settings renders in front.
// Layer stack example:
// 1. Background (Floor) -> Order: 0
// 2. Characters (Player) -> Order: 10
// 3. Foreground (Grass) -> Order: 20A well-planned sorting structure provides a flawless sense of depth in 2D scenes.
Practice Print sorting layer information
Assign "Foreground" to layer and 5 to order. Print Layer: Foreground | Order: 5 to the console.
Starter code
using System;
class Program
{
static void Main()
{
// layer ve order değerlerini tanımlayıp yazdır
}
}Sample solution
using System;
class Program
{
static void Main()
{
string layer = "Foreground";
int order = 5;
Console.WriteLine("Layer: " + layer + " | Order: " + order);
}
}Expected output
Layer: Foreground | Order: 5
Questions and answers
Review the lesson questions together with their answers. To test yourself, solve the lesson interactively.
1 Between two sprites in the same Sorting Layer, which one is rendered in front?
- The one with a numerically higher Order in Layer value Correct answer
- The one positioned at the very top of the Hierarchy list
- The one taking up more disk space in file size
- The one with a lower or negative Order in Layer value
Explanation: Objects with higher Order in Layer values are always drawn on top of lower ones.
2 Set layer order
sr.____ = 10;sr.sortingOrder = 10;Explanation: The sortingOrder property on SpriteRenderer governs rendering priority within a layer.
