Hi, welcome to the forum!
This would be a difficult project even for an experienced Unity programmer. However, there are certainly lots of tutorials to get you going. Check the ones on the Asset Store and the Teaching section of the forum. Also, there is plenty of stuff on YouTube and the internet generally.
oops, thx andee for ur help
