Scale collider from one side for 2d Object
This is sliding stairs through which a player character can climb up and down: 
Now above big stair remain in continuous motion (up and down) so that player climbing area becomes bounded for some time.
For this reason, I require to reduce box collider size from the top side. Normally if I resize collider then it reducing the size from both ends but I want to reduce the size from the top side. Give me your side suggestion to achieve this.
