I'm a beginner programmer... I need help with collision in my program.

[Guest_imported]

i'm attempting to program a game at the present, and I need help with the collision... I don't want the character to be able to walk through characters on the screen... how can I make it so that if they are at that certain coordinate, they get "sent back" to they're previous coordinate (the one they were at right before hitting the obstacle). Thanks.
