How to check if the player is at the top of the ladder?

Hello, I am making a 2.5D game and I need to check if the player is on top of the ladder. Here is how my code works:

  • ladders are trigger colliders
  • if the player touches the ladder,
  • then allow vertical movement (climbing the ladder)

I want the player to be able to stand on top of the ladder and be able to jump off it. So how do I check if the player is at the top or not?

Put another trigger at the top of the ladder.
