# Barricade selection
What's a good way to implement a selection system.
Our barricades will need to be selected, which require a UI with buttons leading to refunding and an inventory selection
Since the barricade selector was already made by my peer, it was rather simple to implement, all i needed to do was use the currently selected barricades position to move the UI and make it use the selectedbarricade access
After this i had to make it so the UI always faced the camera, this makes it so you can always click it.
`transform.LookAt(target.position);`
This caused a slight issue, it would be mirrored.
This can be fixed by using the following formula instead:
`transform.LookAt(2 * transform.position - target.position);`
