# x (property) Get or set the horizontal center position of a sprite on the screen. ## Get Get the horizontal center position of the sprite. ```block let mySprite: Sprite = null let horz = mySprite.x ``` ### Returns * a [number](/types/number) that is the current horizontal center position of sprite on the screen. ## Set ```block let mySprite: Sprite = null mySprite.x = 0 ``` ### Parameter * **value**: the new horizontal center position for the sprite on the screen. ## Sprite locations The sprite image forms a rectangle with some number of pixel columns. The **x** postion of the sprite is the horizontal location of the center column of the sprite's pixels on the screen. The **x** position of the sprite can have a value that is greater than the width of the screen. It can also have a value that is less than the left side of the screen (the left of screen is `0` and the value of the **x** position of the sprite in this case is negative). When this happens, some or all of the sprite isn't visible on the screen. ## Example #example Set the sprite **x** and **y** locations to `64`. Have the sprite say what it's **x** value is. ```blocks namespace SpriteKind { export const Example = SpriteKind.create() } let mySprite = sprites.create(img` 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 2 2 2 2 2 2 2 2 2 2 2 2 7 7 7 5 7 2 2 2 2 2 2 2 2 2 2 7 4 7 7 5 5 7 2 2 2 2 2 2 2 2 7 4 4 7 7 5 5 5 7 2 2 2 2 2 2 7 4 4 4 7 7 5 5 5 5 7 2 2 2 2 7 4 4 4 4 7 7 5 5 5 5 5 7 2 2 7 4 4 4 4 4 7 7 5 5 5 5 5 5 7 7 4 4 4 4 4 4 7 7 5 5 5 5 5 5 7 7 4 4 4 4 4 4 7 7 5 5 5 5 5 7 8 8 7 4 4 4 4 4 7 7 5 5 5 5 7 8 8 8 8 7 4 4 4 4 7 7 5 5 5 7 8 8 8 8 8 8 7 4 4 4 7 7 5 5 7 8 8 8 8 8 8 8 8 7 4 4 7 7 5 7 8 8 8 8 8 8 8 8 8 8 7 4 7 7 7 8 8 8 8 8 8 8 8 8 8 8 8 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 `, SpriteKind.Example) mySprite.x = 64 mySprite.y = 64 mySprite.say("I'm centered at x:" + mySprite.x) ``` ## See also #seealso [y](/reference/sprites/sprite/y), [left](/reference/sprites/sprite/left), [right](/reference/sprites/sprite/right), [top](/reference/sprites/sprite/top), [bottom](/reference/sprites/sprite/bottom)
