make 2 objects on 2d to collide with each other

Im just looking to get to 2d characters to avoid passing through each other , i tried adding rigidbody2d, box colliders ,but wasnt succesful.

I just want a normal collision like a 2d rpg … but also I want the collision to trigger an event with ontriggerenter2D

thank you for the help

You need 2d colliders (not trigger) and 2d rigidbodys on both objects and set IsKinematic on one of the Rigidbodys. You can always use OnColisionEnter2D to call an event
