Legacy GM How can I run through platforms with a jump?



Like in Snow Bros and Bubble Bobble
And please be very specific if you don't know how to do it in Drag'N Drop. I mean: What Action, what Event, what is the function of each variable and stuff like that.
Thanks by the way

There are several ways to do this, most of the easy ones require you to check collisions yourself. (A hacky one I used back in the days was to have the jumpthrough objects change to a completely transparent sprite mask when the player was below them and to a normal mask when the player was above them... easily led to glitches if enemies or other players could also jump around, but it's super-easy to make)

I also recommend checking out MariaEngine, my big general-purpose platform game engine. Jumpthrough blocks is one of the core features.
