What's the simplest way to create 2D colliders that will stop the player? Is there a good example available? I'm trying to make a game that involves what's basically a top-down view of a character navigating a simple maze. Currently I have inputs that move the player by adding to his position in the Translate component and I've tried all sorts of combinations of adding 2D Rigidbodies and Physicsbodies and 2D Colliders and Physics shapes and even turning on gravity and just letting my character "fall" but nothin I seem to do stops the player from just passing freely through everything. The Spaceship example seems to be the closest I get but it only uses collision to destroy things or stop the game and never actually has anything stop anything else from moving. Is there a simple way to create walls that a player can't go through or do I need to do something like using the hit detection to stop the player programatically?
