The documentation is your friend.

The forums are also your friend. Don’t let legend411 scare you off, there are actually plenty of people here willing to help, even answering simple questions. Then there are those like him who just yell at people, “Google it!”. One time I entered an entirely empty thread which was suppose to have a fun story inside. Legend411 was nasty for no reason, scared the guy off, and the moderator locked the thread after giving legend411 a lashing.

When asking questions though, it helps to be as specific as possible unless you purposefully want to have broadened answers.
Besides importing assets, you can also INSTANTIATE gameobjects. That’s more than likely not what you are talking about, unless you want to create bullets after a gun fires.

Just type in INSTANTIATE in the documentation, to find out some code.
