set Position
Set the center position of a sprite on the screen.
sprites.create(null).setPosition(0, 0)Parameters
- x: the new horizontal center position for the sprite on the screen.
- y: the new vertical center position for the sprite on the screen.
Sprite locations
The sprite image forms a rectangle with some number of pixel rows and columns. The x postion of the sprite is the horizontal location of the center column of the sprite’s pixels on the screen. The y postion of the sprite is the vertical location of the center row of the sprite’s pixels.
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.
Similarly, the y position of the sprite can have a value that is greater than the height of the screen. It can also have a value that is less than the top side of the screen (the top of screen is 0 and the value of the y position of the sprite in this case is negative).
Example
Set the sprite x and y locations to 64. Have the sprite say what it’s x and y values are.
namespace SpriteKind {
export const Example = SpriteKind.create()
}
let mySprite = sprites.create(img`
