DarkRP - Certain jobs walk through enitity

I am trying to write a script that stops players from walking through props, but a certain job is allowed to go through the prop/entity. I know how to make the entity and stuff. I just need help with the function that stops/allows ceratin jobs to pass through. Thanks in advanced! Please don’t post comments about how I’m a noob. I really don’t care and just want the answer. I also forgot to say, I am not asking for anyone to just tell me everything (I hate people like that) if there is a wiki for this that would be cool, or a script that has this. That would work also.

Is it a special entity or all entities/props?

It is a specific entity. For example: A door that is see through then some jobs can come in, but some can’t.
