I am checking if the player is on the right or left wall for wall climbing. Everything worked perfectly until I made objects that heal the character. My game is crashing when the character is colliding with the box which drops healing object. But I am already checking if the collision object is null. That would be great if someone could help me.

    ok, where is the code for the new thing you added that you know is causing the problem???
    because it's not in the screenshot.

    could you post a screenshot of the error message? if it's "crashing" it means it's throwing an error, and the error is very specific as to what the problem is, so just read what the error says. post it here if you don't understand.

        You have an object without a collider, your code isn’t ready for this.

        Instead of this:

        If check_left.get_collider().is_in_group

        Do this:

        If check_left.get_collider()!=null and   check_left.get_collider().is_in_group
