Since my camera never moves, I'm trying to detect when my player leaves the camera bounds. I was thinking this could be achieved by adding a collider to the left and right of the camera bounds and firing a ray from my player every update to see if they are still inside the camera bounds or not.
Then I noticed that you can get the pixel width of the camera using pixelWidth. Is there a way I could calculate without physics if my player has left on the screen on either the right or left hand side?

Here's what I do (roughly). Note that this code only checks the top and bottom of the screen, because in my game the player never leaves the center of the screen (horizontally). Also, I'm using a ratio because I want the player to be able to get to a certain point before the camera starts to follow him- I never want the player to completely leave the screen.. so there's a bit of an edge 'safe frame' that I'm checking.
