set Velocity
Set the horizontal and vertical velocities of a sprite.
sprites.create(null).setVelocity(0, 0)Sprites that aren’t projectiles are created without any motion. Every sprite has vx and vy properties which are its horizontal and vertical speeds.
You can set both of the speeds at once to make a sprite move in any direction.
Parameters
- vx: the new horizontal velocity (speed) for the sprite.
- vy: the new vertical velocity (speed) for the sprite.
Example
Create a sprite to bounce off the sides of the screen. Set the vx and vy
velocities to 50.
let mySprite = sprites.create(img`
