After Getting an animated player sprite, I then coded a one way platform so that the player can go between floors by jumping up and landing on the platform (Jump strength was increased due to stairs being unfinished). I did this by using a platform effector and set the surface arc to 180 so the player would be ignored when passing underneath the platform.

After setting up the one way platform and completing the stairs, I then coded the drop down mechanic when the user holds S for 0.5 seconds, allowing the player to move down a level. The code for this changes the effector’s rotational offset to 0 (from 180) when the key S is detected pressed down for 0.5 seconds. I then reset the rotational offset when the player stopped pressing s so the user could jump back up to the platform
