 ## Parameters
 
-* the **sprite** you want to change
-* the kind of [number](/types/number) you want to change for the sprite, like
-    * ``x``, how far up or down the sprite is on the screen (`0`-`4`)

-    * ``direction``, which way the sprite is pointing (this works the same way as the [turn](/reference/game/turn) function)
-    * ``brightness``, how bright the LED sprite is (this works the same way as the [brightness](/reference/led/brightness) function)
-    * ``blink``, how fast the sprite is blinking (the bigger the number is, the faster the sprite is blinking)
+* **property**: the property of the **Sprite** you want to change, like:
