How can I do a enemy follow the player?

I everyone! First, sorry for my bad english, i'm still learning it. I'm from Brazil and it's my first post in the forum :p

I'm making a "car police chase" game, that the player need to run, and the cop cars will try colide with the player.

But i have a question, how can i do the cops follow the player, and at the same time, the cops avoid the solid objects?

Thank you!

Try pathfinding.

Sorry for the delay, I was busy.

Thanks for the help, now I'm understanding how it works. (y)
