Sprite Renderer displays sprite in Scene

The Sprite Renderer component shows a 2D image on a GameObject by assigning a sprite and setting display options.

Execution Sample

Unity

var sr = gameObject.AddComponent<SpriteRenderer>();
sr.sprite = mySprite;
sr.color = Color.red;
sr.flipX = true;
sr.sortingOrder = 5;

This code adds a Sprite Renderer, sets its sprite image, changes color to red, flips it horizontally, and sets its draw order.

Execution Table

Step	Action	Property Changed	Value Set	Effect
1	Add SpriteRenderer component	Component added	SpriteRenderer	GameObject can now display a sprite
2	Assign sprite image	sprite	mySprite	Sprite image is set to display
3	Change color	color	red	Sprite color changes to red tint
4	Flip horizontally	flipX	true	Sprite is flipped left-right
5	Set sorting order	sortingOrder	5	Sprite draws above lower order sprites
6	Render frame	Display	Sprite with red tint, flipped, order 5	Sprite visible in scene with all settings

💡 All properties set, Sprite Renderer displays sprite with specified settings

Variable Tracker

Property	Initial	After Step 2	After Step 3	After Step 4	After Step 5	Final
sprite	null	mySprite	mySprite	mySprite	mySprite	mySprite
color	white	white	red	red	red	red
flipX	false	false	false	true	true	true
sortingOrder	0	0	0	0	5	5

Key Moments - 3 Insights

Why does the sprite not show if I forget to assign the sprite property?

Without assigning the sprite (see step 2 in execution_table), the Sprite Renderer has no image to display, so nothing appears.

What happens if I set flipX to true after setting the sprite?

As shown in step 4, flipX flips the sprite horizontally without changing the sprite image itself.

How does sortingOrder affect which sprite appears on top?

Sprites with higher sortingOrder values (step 5) draw over sprites with lower values, controlling visual layering.

Visual Quiz - 3 Questions

Look at the execution_table, what is the color property after step 3?

A white

B blue

C red

D null

💡 Hint

Check the 'color' property value in the variable_tracker after step 3

At which step does the sprite get flipped horizontally?

A Step 4

B Step 3

C Step 2

D Step 5

💡 Hint

Look at the 'flipX' property change in the execution_table

If sortingOrder was set to 0 instead of 5, what would change?

A Sprite would not be visible

B Sprite would draw below sprites with sortingOrder 5

C Sprite color would change

D Sprite would flip vertically

💡 Hint

Refer to the explanation of sortingOrder effect in key_moments and execution_table step 5

Concept Snapshot

Sprite Renderer component:
- Attach to GameObject to show 2D images
- Assign sprite property to set image
- Use color to tint sprite
- flipX/flipY to flip image
- sortingLayer and sortingOrder control draw order
- Changes appear immediately in scene

Full Transcript

The Sprite Renderer component in Unity lets you display 2D images on GameObjects. First, you add the component to your GameObject. Then you assign a sprite image to the sprite property. You can change the color to tint the sprite, flip it horizontally or vertically using flipX or flipY, and control which sprites appear on top by setting sortingLayer and sortingOrder. Each step changes the component's properties, and the sprite updates visually in the scene. If you forget to assign a sprite, nothing will show. Flipping changes the image orientation without changing the sprite itself. Sorting order determines layering when multiple sprites overlap.
