# Platforms

#### The simplest obstacles are made using the ‘**Mover**’ component. So let’s place a platform that will move back and forth, which can help you jump a gap that’s too wide. Play around with placement until you’re happy, then + add the Mover to it.

Now you can alter the direction the platform will move in, and its speed. Make sure to select ‘**Yes**’ to ‘**Auto-Start**,’ otherwise you will have to create more logic to make it move. 

Selecting ‘**Yes**’ on ‘**Yo-yo**’ will ensure the platform will move **constantly** back and forth, instead of once in one direction.
