please do research before posting, there are plenty of videos on youtube telling you how to do this exact thing, I will link one here but please avoid doing this in the future. Unless you are encountering a scripting error, or need something explained, a video should be enough. Here it is: https://www.youtube.com/watch?v=ByFcI_QGrPg&list=PL5EhU_PzfEF5FNwsX8-aC5qUfT8lCGPlG
