Im making a 1-1 replica of mario bros but i need to find a way to make the sprites not bounce up and down, but side to side.

If you give your sprites only a horizontal velocity, they should only bounce side to side I think. Do you have an example for what you mean exactly?

Well i need the sprite to also have ay velocity because the enemy needs gravity

Ah I see! Well there are two solutions to this:

> Either make the enemies not fall off their platforms (make them go back and forth like [_ **this game** _](https://makecode.com/_KzTcdaCEH3rE))

Or

> You can have invisible walls around your tilemap and have a check if they’re hitting a wall-left or wall-right instead of bounce on wall (Like [_ **this game** _](https://makecode.com/_FXm2CH4h9PMa) – The downside of this is they’ll be turning before reaching the actual edge).
