How do I make it so that when my player (has rigid body) walks into a door (has rigid body) to open?

I already have the player, and door rigid bodys attatched as well as the hinge setup properly, but how it won’t work. What do I do?

If I were you, I might consider using some kind of OnTriggerEnter event to make the door open. Otherwise the only things i can think of are that your player is not using enough force to push (either he is too slow or he is too light) or that the door is too heavy. Also make sure the door is not kinematic.
