How do i make a jump without platform behaviour?

Im having some trouble with the jumping mechanic, and i cant do it with platform behaviour because then everything goes bad. How do i make my character jump & fall without platform behaviour?

Thanks for your help.

I am not sure why would you want that, but making sophisticated platform behaviour might be difficult. I’m new to gd but I did gravity in scratch so, basically u need a grav var set to -1 can be tweaked and make the variable v. Make it that v is always changed by grav and if jumping you can change v by like 15. Moreover u can make stuff solid by shifting y up if glitching through it. I’m not sure but that is the basic concept sorry if I’m wrong
