so I found the “steps for beginners” page on construct and went to the platformer section and I learned that when making the platformer on construct you are able to adjust the gravity, jump height, speed, etc. I learned also that there are a few special behaviors that you can add to make different kinds of platforms you can add the “jump-thru” behavior to make it so that the player character can pass through the platform from underneath but when standing on top the platform will act like a solid (link for the page).
