... unless he did something. ( In my case integrate his account with steam , he can't access Forum 4 lets say. ). I know how to do the if thingy , but where do I place/post it? Like , I need something that won't let a user access a specific forum unless the if statement is met.

Nodes are usually restricted with group permissions:

Admin CP -> Applications -> Display Node Tree -> Permissions

And users can be conditionally placed into groups based on certain criteria using promotions:

Admin CP -> Users -> User Group Promotions

Is it possible to restrict using a code? I need it to check if the user has done something , if no then it won't let him enter. If yes then well , he can enter. I know the piece of code for that but where do I put it to restrict a certain forum?

Done what? Try setting up a usergroup promotion, the options are plentiful, and then you can set permissions for that user group.
