Platformer Help Please!

Hello, I am making a platformer type game. It involves you a fellow Stickman citizen who is a security guard working for the underground tunnel. Basically, you get locked out of the security office and now need to find the key card. For some reason, when trying to get on the road, the stairs block me from going up. However, I have a solution but I do not know how to do it.

Basically the solution goes like this: When on specific object, you should be able to stand on it. If you press the “S” button/crouch button. You go through the object and end up underneath the object.

Is there a way to do that.

Is the object you stand on a platform object? If so, change the type to “Jumpthru platform”:

When the down key is pressed the player will drop through. If you have a specific key for doing this, you can include a “Simulate down key press” on the player object:
